Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Why choose Bitcoin Cash?

Some of you might be coming to this sub, and wondering why so many people support Bitcoin Cash. This is directly answered in the pinned FAQ, and also briefly goes over the history of the sub. Now onto why Bitcoin Cash has huge potential when it comes to changing the world:
Bitcoin Cash was created with the purpose of bringing economic freedom to everyone all across the globe. With the current banking, financial, and payment systems, there are many issues when it comes to the usability of money. These issues are:
- Sending money across the globe without having to pay high fees (percentage fees), and waiting days or even weeks for your transfer to go through
- Having payment options like Visa and Mastercard that help deal with high-volume business, but having to pay a flat fee ($0.15), and a fee of 2%-3% per purchase
- Having full control over your money, so the government can't devalue your savings by printing more money for their personal interests
- Being able to use your money however you like, without having to get permission from an intermediary, middleman, or financial institution
- Being able to know how much money will be circulating at any given time in the future
- Paying high fees (4%+) for converting currency when travelling
Let's take a look at how Bitcoin Cash solves these problems:
Remittance
When it comes to sending money across the globe from one bank account to another, often times the fees will be very high because when your bank is sending money, it has to go through several intermediary banks that each take from the initial amount of money, making the process slow, and expensive. Currently, Western Union is advertising "free" transfers of currency across the globe. Seems like a good deal, right? Well here's the thing: they're tricking you into thinking that transfers are free when they're actually making money off of the exchange rate. We believe that money (digital cash) should be as frictionless as possible, and that a user shouldn't have to deal with transfer fees, and have to get permission to transfer their money from one bank to another. Currently, the fees on Bitcoin Cash are only $0.0007, and we plan on keeping them that low.
Payment Systems
When it comes to traditional payment systems, like Visa, Mastercard, and American Express, credit card companies often charge a 2%-3% fee on every transaction that takes place, and a transaction can take anywhere from 24-36 hours to confirm, and go into a merchant's bank account. These payment systems are both slow and expensive. With Bitcoin Cash, your funds are available instantly for you to spend, but if you want to take extra security measures, you can always wait ~10 minutes for a confirmation to go through.
Control Over Your Own Money
With the banking system as we currently know it, one of the biggest problems is the lack of control your have over your own money. Every year, people are forced to pay taxes to politicians only to have their money basically wasted on providing effectively nothing to them. Bitcoin Cash solves this problem by giving you full control over your money. Making a wallet does not require anyone to give ID, personal information, or anything that could potentially lead to the government having any say in what you can do with your hard-earned money. Another issue with traditional currencies is the inflationary nature of them. This is another form of taxation that doesn't appear to be as bad as taxing, but it's just a different way of taking money from the hands of citizens. When the government prints more money, your savings get devalued, meaning that the government has effectively stolen money without physically "stealing" it. With Bitcoin Cash, the inflation relies on a purely mathematical system in which the maximum number of Bitcoins will always be 21 million. With mathematical certainty, you can always be sure of the exact supply of Bitcoins based on the block number. I made a graph that helps illustrate this with >99.99997% accuracy on how many Bitcoin Cash will be in circulation based on the block height. This works for Bitcoin, and Bitcoin SV too. You can check the accuracy by putting the block height/number in the brackets of the second expression.
Currency Conversion
Have you ever travelled to another country where you had to convert to the local currency in order to be able to use it? If so, you would've realized that conversion rates can often be very high, and it is impractical to do unless you're converting a large sum of money. Our idea is to increase merchant adoption so that Bitcoin Cash can have its own economy, so it doesn't matter where in the world you are, you can always use Bitcoin Cash, and not have to worry about conversion fees. If you want to "convert" to another currency, you can always use SLP tokens that will eventually come in a variety of local fiat currencies in the near future. Tether USDT is already planning to make SLP tokens too. This is also a great alternative if you aren't sure whether you want to put your money into crypto, and want to stick with fiat instead. Think of SLP tokens as "paper" tokens on top of Bitcoin Cash that can be sent and received for fractions of a penny!
How to use Bitcoin Cash for Buying Goods and Services
Right now, there are many ways you can use Bitcoin Cash, including local usage, and online usage. If you want to see which merchants near you accept Bitcoin Cash, you can check using map.bitcoin.com and see which local merchants are accepting Bitcoin Cash. If you want to buy things online, you can use purse.io, and get 30% off on any Amazon purchase, so you contribute to the economy of growing Bitcoin Cash, and get a great deal for any item you want to buy!
TL;DR: Bitcoin Cash is sound money which you have full control over your own money, and allows you to send any amount of money, anywhere in the world, instantly, and practically for free. If you have any additional questions, feel free to comment.

small passive income while browsing the web

Introduction
If you were on the internet in the late 1990s, you might remember companies like "AllAdvantage" that promised to pay you to browse the web. You could install a program that tracked your browsing and showed you targeted ads at the top of the screen, then "AllAdvantage" would give you a cut of the ad revenue you generated.
These schemes largely disappeared after the dot-com crash. But Brendan Eich, the creator of the JavaScript programming language and cofounder and former CTO of Mozilla, thinks his company Brave Software has found a way to revive that old idea.
What is it?
Brave makes a browser based on Google Chrome that blocks tracking scripts and other technologies that spy on your online activity. As a result, it also blocks many web ads; if you visit any website using the Brave browser, you won’t see any ads. But Brave will give users the option to see ads that Eich says will respect your privacy. The ads will appear as desktop notifications, he says, not as replacements for the ads the Brave browser blocks. So you still won’t see ads on any website, but you might see them on the right lower corner of your screen. If you choose to see these ads, you’ll get 70 percent of the revenue they generate.
Eich hopes Brave can solve two of the web's most vexing problems the privacy and revenue problem by turning the traditional digital advertising model on its head. Today, ad networks pay sites for ad space and web browsers like Brave and Chrome deliver content from those publishers to users. Brave is trying to put the browser in the center of the advertising experience. Instead of paying publishers directly, ad networks would pay Brave, which will pass part of the money to users and keep a cut for itself.
By handling advertising in the browser on your device, Brave says it will be able to target ads without sending your data to the cloud, and protect your privacy. When you interact with an ad on Brave, the browser sends notice to the company's servers, but doesn't include any identifying information. Eich sees four sets of winners: browser makers get paid; users get paid, and get more privacy; advertisers can target pitches without running afoul of European privacy regulations; and publishers can survive in a world where many users are installing ad blockers.
Publishers and ad networks might bristle at the idea of putting browser makers in the middle of their business. But in recent years browsers have taken a more active role in shaping the web, instead of merely displaying a website’s content. Chrome now blocks ads on a small number of sites with particularly egregious advertising practices, while browsers like Firefox and Safari have added privacy protections. Meanwhile, browser plugins are giving users more control over their experience. There are Chrome extensions, for example, that let you change Facebook's color scheme, or change the way images are displayed on Pinterest. And of course there are extensions that block all ads.
Trying to win advertisers and publishers to a new model isn't Brave's only challenge. It also needs users. Eich says Brave has 15 million users and is growing.
Brave will give users a 70 percent cut of its advertising revenue, which Eich estimates could work out to about $10 a month. Brave will pay users with its own bitcoin-style "cryptocurrency” called Basic Attention Tokens or BAT, which has traded for as little as 24 cents over the past 12 months, according to CoinMarketCap. You can exchange the BAT you have received for viewing ads into USD, EUR, GBP, CHF and many more currencies.
The company offers a service through the cryptocurrency exchange Uphold to allow users to change, sell and buy BAT or donate it to publishers, and for publishers to exchange the BAT they receive for dollars. Advertisers like HomeDepot or recent campaigns included brands such as Verizon, Newegg, Chipotle, and PayPal/Honey, in addition to earlier campaigns by Amazon, Harry’s Razors, Intel, CBS, KIND snacks, Logitech, Lenovo, Grubhub, Belkin, Quickbooks, Evernote and some of cryptocurrency related companies, will be able to buy ads either with BAT or with traditional currencies.
Eich says Brave opted to create its own tokens using the Ethereum cryptocurrency platform in part to avoid regulatory requirements, such as verifying users' identifies, that partners like Uphold are better equipped to handle.
Estimated revenue? (depending on the country you live in the revenue can be higher or lower)
I made around 3oo$ so far this year using 3 devices, just for viewing some ads.
5 months so far july is not included if you calculate it down for 1 device, 100$/5months = 20$ a month just for viewing ads, you would need to buy risky stocks worth of 2000$ to get the same amount per month.
can only recommend everyone to try it, not every country has the same number of advertisers so you probably get the most out of it when you live in the USA.
If you are interested here is a quick guide how to set it up to get the max amount out of Brave:

Wisdom Chian:AccountState

In the current block chain world, there are mainly two ways of record preservation, UTXO mode and Account mode. Bitcoin adopts UTXO model, Ethereum/EOS adopts Account model, and WisdomChian also adopts Account model. Today we will explain in detail why WisdomChian also adopted the account model.
Before introducing the UTXO model and the Account balance model, we have to first introduce the most important concepts and data structures in their two or even all block chain applications, that is, Block. The block chain is actually made up of a list of growing chains, which contains many records, that is, blocks.
📷
UTXO model
In the UTXO model, transactions only represent changes in the UTXO collection. The concept of accounts and balances is a higher abstraction on the UTXO collection. The concept of accounts and balances only exists in wallets. Let's look at some examples to understand the difference.
First, Bitcoin UTXO can not be partially expended. If a user wants to spend 0.5 Bitcoins, but he has 1 Bitcoins in his UTXO collection.He has to send half a Bitcoin to himself to get change at the same time as he sends half a Bitcoin to someone else. If he doesn't send it to himself, he will pay 0.5 Bitcoin to the miner.
📷
Second, Bitcoin itself does not store account balances. Users only need to sign these UTXO with the private key to spend Bitcoins. The digital wallet makes the Bitcoin blockchain look like it has the function of user account balance. This is not the case.
How visual wallets work in Bitcoin
Bitcoin's UTXO system works well, partly because digital wallets can help to accomplish most of the work related to transactions. Including but not limited to:
a) Processing UTXO
b) Storage key
c) Set transaction costs
d) Provide change address
e) Aggregated UTXO (display available, pending and total balance)
Trading in the UTXO model is similar to paper currency. Each account shows how much money it has by calculating the sum of all the paper money (UTXO) in the wallet (corresponding to the wallet address). When we want to spend money, we need to use one or more UTXO with enough cost and we may get a new UTXO. Each UTXO can only be used once, because once UTXO is expended, it will be deleted from the UTXO pool.
All in all, we know that:
Bitcoin blockchain does not store account balance
Bitcoin Wallet Holds secret key
If it is included in the transaction, it will cost the entire UTXO (in some cases, the change is in the form of a new UTXO).
WisdomChain
WisdomChain adopts the same Account transaction structure as ETH. Unlike Ethernet, there are two very different data in Ethernet: permanent data and temporary data. An example of permanent data is a transaction, which, when fully confirmed, will be recorded in the transactiontrie and will never change. An example of temporary data is the balance on a specific Ethereum account address. The balance of the account address is stored in statetrie and will be changed whenever the transaction of the particular account changes. In Ethereum, permanent data (such as mined transactions) and temporary data (such as account balances) are stored separately. Ethereum uses trie data structure to manage data.
And about WisdomChain, when the transaction is initiated, the node will calculate the status information after transaction based on the current state information and transaction content in the virtual machine, and store the relevant hash value of the state information along with the transaction. When the transaction is packaged by a miner, the remaining nodes store data on the Merkletrees to ensure that the state information of their nodes and other nodes in the network is consistent.
So WisdomChain's records are kept like banks. Similar to using ATM / debit cards, banks track the amount of each debit card. When we need to spend money, the bank checks its records to make sure we have enough balance before confirming the transaction.
Of course, WisdomChain uses the Account transaction structure, which inevitably leads to the problems of the Account transaction structure itself. First, there is no dependency between Account model transactions, so the problem of replay attacks needs to be solved. Second, for the realization of lightning network, Plasma and so on, users need more complex Proof mechanism to produce evidence. The state transfer of sub chains to the main chain requires more complicated protocols.

Guide for novice crypto investors

Bitcoin is a decentralized system, any user of which could control the movement of their own funds. You can use the currency to make transactions, pay for purchases, receive transfers, and exchange it for cash. For transactions, a special address is used, encrypted with a 16-character key. The buyer decodes the code to transfer bitcoins to the specified address.

Bitcoin Mining

Mining is a process that ensures the security of the BTC system, which adds new blocks to the blockchain in chronological order (new transactions). Blocks are added when the codes are decrypted, the transaction is completed, and bitcoins are transferred or exchanged.
The main cryptocurrency is generated by miners using software that solves cryptographic problems. The reward for a new block is agreed by all network participants, but usually amounts to 12.5 bitcoins. Part of the user fees for transactions also goes to reward the miners. Cryptographic tasks become more complex every year to prevent inflation (mining complexity).

Features of the transaction

  1. Anonymity. The address that Bitcoin is sent to consists of 30 characters. You can track the flow of transactions, but the address is not always associated with a real person.
  2. Security. The balance of bitcoins is fixed in a cryptographic system with a public key. Only the owner of a private key can send cryptocurrency to other addresses.
  3. Unable to cancel. It is no longer possible to cancel the transaction after the transaction has been completed.
  4. Deregulation. Everyone can use cryptocurrency.
  5. Coverage and speed. Information about the transaction is transmitted incredibly quickly, and confirmation is received within a few minutes. No one knows the buyer’s physical location.

Where to buy Bitcoin?

There are Deposit systems that use crypto-exchanges. So, to buy Bitcoin, you will first need to top up your balance, buy the digital currency itself, and then withdraw it to your Bitcoin wallet, paying a Commission for withdrawing coins. The cheapest method of buying is buying on the stock exchange. The exchange rate is as close as possible to the market rate.

BTC rate

The current exchange rate of the coin is calculated based on the average price on the largest currency exchanges. For example, you can track the exchange rate on our Bitniex exchange. The Bitcoin exchange rate is constantly changing, during the day it can change by 10% in one direction or another.

The choice of crypto-currency wallet

A cryptocurrency wallet is a place where digital currency will be stored. The most secure method of storage is using paper or electronic wallets.

TOP secure cryptocurrency wallets

These wallets are one of the most secure crypto wallets in the world:

What is Delegated Harvesting and how does it work?

What is Delegated Harvesting and how does it work?

https://preview.redd.it/030pghigzkg51.png?width=1024&format=png&auto=webp&s=ee51e1f5bb87938ab610ee07951ad4daed798a20

Delegated harvesting lets you passively earn block rewards on-chain

Symbol has a noteworthy economic system that allows you to passively earn coin rewards just as if you were mining. This is better than staking rewards given by exchanges since you don’t need to put your coins on an exchange and you are earning actual block rewards.
On most other blockchains you have to operate a node in order to earn block rewards. That can be expensive and difficult for casual users. With our delegated harvesting system, your rights to earn rewards are based on how many XYM coins you are holding, but Symbol lets you delegate those rights to someone else’s node so they will earn rewards on your behalf. You’ll earn on-chain block rewards even when your computer is turned off, and the rewards are sent to you instantly, the moment they are earned. It requires a minimum balance of 10,000 XYM, and you can do it easily through a dashboard. Here’s how it all works.

Let’s chain some blocks

A quick block reward review: the process of adding transactions and other data to a blockchain is called creating blocks, and it’s what every computer in the network is trying to do. Blockchains pay a coin reward to the first account to create a new accepted block. The reward is called a block reward. If new coins are created to pay the block reward, it’s called mining. Symbol doesn’t create new coins for block rewards so it uses the term harvesting instead, but it’s nearly the same as mining.

We want proof

What’s the point of all this mining and harvesting? The problem is that anyone can join the network anonymously, so we would expect cheaters sending false data so they can spend the same coins twice or make other fake transactions. If we don’t know who is trustworthy, how do we choose who gets “write access” to account balances?
Bitcoin and many early protocols use a Proof of Work (POW) system. In POW every computer in the network is processing calculations as fast as possible until someone gets the right number. Whoever gets it first creates the next block. POW is effective at discouraging cheaters because it’s expensive to buy and power all the machines needed to mine profitably. Anyone who could make such a mining investment won’t want to risk being rejected.

Not that proof, different proof

The biggest drawback of POW is its insatiable consumption of electricity. It’s estimated that bitcoin alone consumes a quarter percent of global energy production. Unfortunately, that’s not a side effect, it’s the point; the more expensive it is to create blocks, the harder it is for bad actors to take over. In the early days users could mine POW coins on a laptop, but today it’s so expensive that only large industrial operators are competitive.
The most popular alternative system is Proof of Stake. POS is well-tested and has proven secure at large scale, and best of all, it requires no special energy usage. In a POS system, the protocol chooses an account at random to be the next block creator. However, an account’s chance of being chosen depends on the number of coins it holds. So users with the highest account balances have the highest chances of creating new blocks. This is a good way to ensure security, but one downside is that it encourages hoarding.

Proof of stake plus

Symbol uses a Proof of Stake Plus (POS+) system, which adds a few weighting factors on top of Proof of Stake to incentivize a healthier economic system. For example, POS+ gives an advantage to accounts that have many recent transactions in order to encourage network usage. So if you need to pay a lot of transaction fees, that expense can be offset somewhat by higher block rewards.
This addresses the hoarding problem, but not the expense and difficulty of running a node. We want everyone to participate in harvesting whether or not they are paying to run a node. Owning a minimum of 10,000 XYM automatically gives you the right to harvest, so the idea is to use your earning rights on someone else’s node. This is where delegating your stake comes in.

Keep your keys in your pocket

The tricky part is that if you gave a node operator direct access to your stake, they would be able to see your private key and possibly take your funds. Symbol solves this problem by creating a proxy account with a different private key that’s used only for delegated harvesting. This allows you to delegate your harvesting rights to any available node without allowing them access to your account.

There’s no minimum holding time or obligations for your coins, and you can spend them just as easily as non-delegated accounts as long as your balance is 10,000 or above. If your account drops below 10,000 it will simply stop harvesting with no side effects. If the node you are working with is going down a lot or otherwise annoying you, just use the dashboard to stop delegating or switch your delegation to another node any time you like.

What’s in a block reward?

There’s one more detail: any node that you have delegated to will keep 25% of the rewards earned by your delegated stake. This is their incentive to keep their node running. If you don’t like giving them a cut, you need to run your own node. Now the good part: every block reward on the Symbol public chain will contain new tokens added for inflation, incentives for early adopters, and will also contain all transaction fees paid. 100% of transaction fees are returned to harvesters in block rewards. The system is estimated to provide about 3% to 4% returns for delegated harvesters, although rewards could be lower or higher if there are a lot of transaction fees paid.

A quick hypothetical example

Let’s say there are 1 billion XYM tokens staked on the Symbol public chain. Your account balance is 20,000. This gives you about a 1 in 50,000 chance to be the harvester of any given block. Blocks are created every 15 seconds, which adds up to 5,760 blocks per day. Your account would be expected to harvest a block reward about once every 8.7 days.

Configuration of delegated harvesting

The Symbol public chain has a requirement of 10,000 XYM minimum balance for delegated harvesting, but if you are running your own Symbol blockchain you can change it to any token and any amount you want. You can also change the inflation rate, transaction fees, and other economy settings. In a corporate private network there is usually little need for decentralization and incentives since everyone on the network will be known and trusted. In this type of private chain you can even remove transaction fees. However, since Symbol is open-source, it’s also simple to run your own public version configured with any requirements you need.

On-chain staking rewards

Staking rewards are becoming more common on exchanges, and many users are coming to expect it. That’s good because staking rewards provide more opportunity for users to earn coins and encourage new users to enter the industry. Unfortunately these custodial exchanges and wallets require users to give up their keys. It’s nearly always more secure to hold tokens off exchanges, especially if holding long term. Symbol and its original version NEM are unique in their method of allowing users to delegate their stakes and earn rewards without giving up custody and without any risk of sharing their private keys. Delegated harvesting on Symbol is likely to be the best way in the blockchain industry for users to earn on-chain staking rewards without the chore and expense of running a node.

Delegated harvesting lets you passively earn block rewards on-chain

Symbol has a noteworthy economic system that allows you to passively earn coin rewards just as if you were mining. This is better than staking rewards given by exchanges since you don’t need to put your coins on an exchange and you are earning actual block rewards.
On most other blockchains you have to operate a node in order to earn block rewards. That can be expensive and difficult for casual users. With our delegated harvesting system, your rights to earn rewards are based on how many XYM coins you are holding, but Symbol lets you delegate those rights to someone else’s node so they will earn rewards on your behalf. You’ll earn on-chain block rewards even when your computer is turned off, and the rewards are sent to you instantly, the moment they are earned. It requires a minimum balance of 10,000 XYM, and you can do it easily through a dashboard. Here’s how it all works.

How Bitcoin Mining Works

When you hear about bitcoin “mining,” you envisage coins being dug out of the ground. But bitcoin isn’t physical, so why do we call it mining?
Similar to gold mining, bitcoins exist in the protocol’s design just as the gold exists underground, but they haven’t been brought out into the light yet, just as the gold hasn’t yet been dug up.
The bitcoin protocol stipulates that a maximum of 21 million bitcoins will exist at some point. What miners do is bring them out into the light, a few at a time. Once miners finish mining all these coins, there won’t be more coins rolling out unless the bitcoin protocol changes to allow for a larger supply. Miners get paid in transaction fees for creating blocks of validated transactions and including them in the blockchain.
To understand how bitcoin mining works, let’s backtrack a little bit and talk about nodes. A node is a powerful computer that runs the bitcoin software and fully validates transactions and blocks. Since the bitcoin network is decentralized these nodes are collectively responsible for confirming pending transactions.
Anyone can run a node—you just download the free bitcoin software. The drawback is that it consumes energy and storage space – the network at time of writing takes hundreds of gigabytes of data. Nodes spread bitcoin transactions around the network. One node will send information to a few nodes that it knows, who will relay the information to nodes that they know, etc. That way, the pending transaction ends up getting around the whole network pretty quickly.
Some nodes are mining nodes,usually referred to as miners. These chunk outstanding transactions into blocks and add them to the blockchain. How do they do this? By solving a complex mathematical puzzle that is part of the bitcoin program, and including the answer in the block.
The puzzle that needs solving is to find a number that, when combined with the data in the block and passed through a hash function (which converts input data of any size into output data of a fixed length, produces a result that is within a certain range.
For trivia lovers, this number is called a “nonce”, which is an abbreviation of “number used once.” In the blockchain, the nonce is an integer between 0 and 4,294,967,296.
How do they find this number? By guessing at random. The hash function makes it impossible to predict what the output will be. So, miners guess the mystery number and apply the hash function to the combination of that guessed number and the data in the block. The resulting hash starts with a certain number of zeroes. There’s no way of knowing which number will work, because two consecutive integers will give wildly varying results. What’s more, there may be several nonces that produce the desired result, or there may be none. In that case, the miners keep trying but with a different block configuration.
The difficulty of the calculation (the required number of zeros at the beginning of the hash string) is adjusted frequently, so that it takes on average about 10 minutes to process a block.
Why 10 minutes? That is the amount of time that the bitcoin developers think is necessary for a steady and diminishing flow of new coins until the maximum number of 21 million is reached (expected some time in 2140).
The first miner to get a resulting hash within the desired range announces its victory to the rest of the network. All the other miners immediately stop work on that block and start trying to figure out the mystery number for the next one. As a reward for its work, the victorious miner gets some new bitcoin.
At the time of writing, the reward is 6.25 bitcoins per block, which is worth around $56,000 in June 2020.
However, it’s not nearly as cushy a deal as it sounds. There are a lot of mining nodes competing for that reward, and the more computing power you have and the more guessing calculations you can perform, the luckier you are.
Also, the costs of being a mining node are considerable, not only because of the powerful hardware needed, but also because of the large amounts of electricity consumed by these processors.
And, the number of bitcoins awarded as a reward for solving the puzzle will decrease. It’s 6.25 now, but it halves every four years or so (the next one is expected in 2024). The value of bitcoin relative to cost of electricity and hardware could go up over the next few years to partially compensate for this reduction, but it’s not certain.
If you’ve made it this far, then congratulations! There is still so much more to explain about the system, but at least now you have an idea of the broad outline of the genius of the programming and the concept. For the first time we have a system that allows for convenient digital transfers in a decentralized, trust-free and tamper-proof way.

Harmony Updated Economics

Dear Harmony community,
After careful consideration we have updated the economic model of our network ahead of our upcoming open staking launch. In this new model, the total reward across the network (issuance plus transaction fees) will remain constant regardless of average block time and staking ratio. The goal of this change is to achieve a higher staking ratio, to simplify the model and to create a path to 0 issuance, all of which we believe will bring long term benefits for Harmony.
 
TLDR:
 
Why aim for a higher staking ratio?
A higher staking ratio is beneficial for two reasons. First, the staking ratio is a barometer for the health of a PoS chain. A high staking ratio (above 60%) means that the network is highly secure since mounting a 33% attack would require at least 20% of the token supply. Just as important, a high staking percentage signals a large and loyal community that is committed to the project for the long term. If 60% or more tokens are bonded in the staking contract, you know that a majority of tokens belong to HODLers.
The second benefit of a higher staking ratio is that it creates organic demand for the ONE token. In the long run adoption of on-chain applications will drive network usage and demand for ONE, but the first major use case and demand driver for the token will be staking. We believe that higher staking yields will lead to more desire to stake ONE, thus driving more demand.
 
Why is simplicity important?
Bitcoin demonstrates the power of simplicity. The economic model is so simple you can express it in one sentence: “Issuance halving every 4 years until a maximum supply of 21 million.” The simplicity of Bitcoin’s economic model makes it easy for people to understand so that it’s easy to onboard new community members. The more understandable the model is, the easier it is to spread. Conversely the more complicated the economics are, the less likely the protocol is to reach mass adoption.
For this reason, we strived to create an economic model that could also be explained in one sentence. Here’s ours: “Issuance plus transaction fees set to 441M ONE per year.” An advantage of this simple model is that it becomes easy for validators to project their future rewards and it becomes easy for token holders to project future circulating supply. This predictability gives the protocol a stable economic base for our stakeholders to rely on.
 
Transaction fees
One of the potential problems of Bitcoin’s economic model is that it is unclear if or when transaction fees will be able to compensate for the decreasing block reward issuance. This presents a potential time bomb within the protocol. For any protocol to survive in the long term, it will need to bring in enough transaction fees to at least sustain the cost of operating and securing the network. However, it’s nearly impossible to predict when transaction fees will be adequate to sustain a network in place of issuance.
Our model solves this problem by allowing transaction fees to offset issuance. Thus as network usage increases, issuance decreases by the same amount. When the network is fully mature and can sustain itself on transaction fees alone, issuance will naturally fall to zero. Rather than trying to predict the future, we structure our model so that it adjusts automatically when the timing is right. This way we get the benefit of a stable source of funding to secure the network while also maintaining the potential to have a finite supply of ONE tokens like Bitcoin.
 
Differences from the old model
You might be wondering how this new model is different from the old one. The old model had a variable issuance. As the percentage of tokens staked increased, the annual issuance decreased from ~500M at 0% to 0 ONE at or above 80%. With the new model’s constant issuance of 441M, the reward is slightly smaller at staking ratios of less than 10% but significantly higher at higher staking ratios greater than 10%.
This means that the rewards are more generous! Stakers and validators should be excited that there will be more rewards to be claimed.
 
Why did we change the model?
We changed the model because the assumptions and judgments underlying the original model changed. As John Maynard Keynes said, “When the facts change, I change my mind. What do you do?”
Initially we wanted to have as low an issuance as possible while maintaining reasonable security so that we could minimize inflation. However, we realized that the potential harm from inflation would pale in comparison to the benefits of creating a strong community of validators and stakers in the early stages of the network. Furthermore, we realized we could put a cap on long term inflation by using transaction fees as a way to offset issuance. Therefore we decided that increasing issuance was a worthwhile trade off.
Another assumption in the old model was that staking was inherently competitive with use cases that rely on collateralization such as DeFi. We wanted a lower staking ratio so that a portion of token supply would remain unstaked for these applications. Since then, a new concept called “staking derivatives” shows promise to eliminate this competition as it would allow for derivatives representing staked tokens to be used as collateral instead.
Finally, the original model issued a constant amount of ONE per block. However, we now realize that our block time will decrease over time as we optimize the protocol but this would in turn increase issuance in the old model. So we designed the new reward system such that reward per block will adjust with a change in the time between blocks to keep annual rate of issuance constant.
 
Join the discussion
If you are curious to learn more about our economic model we encourage you to check out our spreadsheet and to join the discussion by replying to this post. If you are a validator or delegator and want to see what this new economic model will mean for your rewards, we are creating a staking calculator which you can use to explore your staking rewards under different circumstances.

How Blockchain.com harms the cryptocurrency community

How Blockchain.com harms the cryptocurrency community
This post has been written to draw Blockchain.com's attention to the issues of its product.
Blockchain.com (formerly Blockchain.info) was founded in 2011 and with no doubt has helped the Bitcoin community to create a block explorer and has proven itself as a valuable service. Millions of people from all over the world use their wallet. However, time goes on, Bitcoin develops, but one of the main cryptocurrency companies not only slows down the process of its development, but also discredits the usability of cryptocurrencies. Why is that? We have tried to explain that in this post.
https://preview.redd.it/i0yk7qraqkw41.jpg?width=1024&format=pjpg&auto=webp&s=963dc18551d2900bca456bfa3a6cfd3636c7c93c

1. Lack of Segwit Address Support

This is the most painful problem for our service. To receive cryptocurrency we use segwit addresses by default. If a customer contacts our support, we can of course change an address in an order to P2SH (the one that begins with number "3"), but it reduces the usability of the service. Why don't we use P2SH by default? It is less beneficial both for us and for our client, as the cost of the consolidation of the transaction is taken into account when calculating the exchange rate. With a high network load and with orders for a small amount, the commission becomes significant. To compare — segwit addresses (or Bech32 that starts with "bc1") are 15% more advantageous than P2SH.
Segwit (Segregated Witness) was activated in 2017. At the end of the same year the CEO of Blockchain.info announced its support starting from (most likely) 2018. We can understand certain fears at the beginning of the way, as the company's security system is for sure not that bad. However more than 2 years have passed since then and that is a lot for the crypto world.

2. Using Legacy (P2PKH) Addresses Only

As of now only a P2PKH address (that starts with number "1") is used in the Blockchain.com wallet to receive cryptocurrency. Why is that bad? It is unfavorable for the users of this wallet. They spend 29% more than those using P2SH addresses.

3. Confusion with PAX and USD Digital

Changing the names of the currencies from one to another only in a Blockchain.com wallet is a rather strange decision. The key problem is that nowhere in the wallet are there any clues that this is an ERC-20 PAX token on the Ethereum blockchain. New wallet users will most likely be confused by this.
We sometimes get questions: "do we have USD Digital to buy or to sell?" and our technical support is forced to explain that it is PAX.

4. Incompetence of mobile application developers

In fact, this post was inspired by this particular problem. We will not focus on performance or shortcomings, we will just tell you about the main issue.
It is worth starting with questions. What problem does a mobile application solve when a person needs to pay for something? What is the best way to fill in the recipient address and the payment amount on the smartphone? Answer: QR code.
Scanning the QR code in this application is done not just badly, but also in such a way that creates maximum number of problems for a user.
The fact is that in the Android application when scanning code with the bitcoin:
?amount=, the value of the amount to be inserted in the corresponding field may differ from the encoded value by 1-100 Satoshi! Our team simply does not understand how this was implemented.
Do not believe? Try it yourself. Amount to insert — 0.00143452 BTC
bitcoin:3LAxDr5CxwBJT4tCejV8rpAXETz7bUH3tG?amount=0.00143452
After receiving information on such a problem from our users, we began to monitor updates to this application. After 2 updates had come out, the problem was not fixed.
And what about iOS? When scanning a QR code with a sum in iOS , the sum value is simply not inserted into the field! No comments. Bravo!
Blockchain.com wallet has different currencies, not just Bitcoin. Let's try Ethereum. You want to scan QR codes for Ethereum payment with the relevant sum? There is no such possibility. The application will respond with an "Invalid address" to all such codes:
  • eth:
    ?amount=
  • ether:
    ?amount=
  • ethereum:
    ?amount=
For BitcoinCash, the task of identifying the amount in the line is also an impossible task. Line with wallet bitcoincash:qpk0689rt3xkzlw8ap4yy72amp2zpws6zujkcgavptconsidered true, but with the amount bitcoincash:qpk0689rt3xkzlw8ap4yy72amp2zpws6zujkcgavpt?amount=0.1 — "Invalid address"
But there are applications that understand all such formats, or at least one of them. The string parsing function is pretty trivial and should not be a problem for the developer.
This article has been written based on the experience of using the application of the members of our team (who have used it for many years) and our users.
We encourage Blockchain.com to fix at least 3 of the 4 problems that we covered in this article. We still hope that the company will work on the bugs and will earn back trust of its users.
In the meantime — use other applications! ;)

ACIS-mining and its 3 best algorithms

ACIS-mining and its 3 best algorithms
Hello. 👋🏻 Today we will tell you about ACIS-mining and its 3 best algorithms.
📌 With the advent of ASICs for mining, it became possible to mine Bitcoin in much larger quantities than using video cards. ASIC is an integrated circuit specialized to solve a specific problem, in our case, only for bitcoin mining. These schemes are many times more profitable than video cards, because with more power (hash calculation speed) they consume much less energy. This served as a good reason to create a cryptocurrency mining business.
📌 In bitcoin and other blockchain systems, the complexity of mining depends on how quickly the miners find the block. Compared with the GPU and CPU, specialized #ASIC miners solve #PoW puzzles better and are therefore able to quickly find new blocks.
📌 Since PoW is still the preferred mining consensus mechanism, we propose to take a multiple algorithm approach. Instead of trying to use algorithms which are ASIC resistant, we propose to use algorithms which have had ASIC miners for quite some time. These are: #SHA256, #Scrypt, and #X11.
🔹 The SHA-256 algorithm has a number of advantages over other information protection technologies. Over the years of use in the cryptocurrency industry, he has shown his resistance to various hacking attempts.
🔹 Scrypt is a cryptocurrency mining algorithm that was previously interesting to many single miners in view of its resistance to the so-called “hardware attack”. The speed of creating blocks in a Scrypt-based blockchain is about 30 seconds. The hashrate, like Ethash, is measured in Megahash per second. Scrypt, first of all, became popular due to its use in Litecoin #cryptocurrency.
🔹 X11 is an encryption algorithm in which eleven are used instead of one function. This means that this technology can provide a high degree of security, because in order to harm the system, an attacker will have to crack all 11 functions, which is very unlikely, because the changes made will be visible after breaking the first function, and developers will have a lot of time to protect the system before the hacker reaches the eleventh function.
Since these miners are already in wide use, the distribution of mining should be fair and even. Furthermore, the use of three different algorithms results in a far less chance of any single person gaining a majority hash rate share. Lastly, we use the Multishield difficulty adjustment algorithm to prevent difficulty spike issues resulting from burst mining.

The impact of Dash on the PYRK platform

The impact of Dash on the PYRK platform
Greetings! 👋🏻 Today we will tell you about the impact of Dash on the PYRK platform.
🔗 PYRK is a privacy centric cryptographic currency based on the work of Bitcoin, Dash, and Digibyte. #PYRK is officially a fork of Dash v0.12.3.4 with Multi-Algorithm mining and Multishield difficulty adjustment taken from Digibyte.
🔗 Dash is based on a distributed registry. Operations in DASH are recorded in the #blockchain. However, unlike Bitcoin, a transaction is divided into several parts, which are mixed with parts of other transactions and are recorded in the blockchain in this form. As a result, an outside observer sees in his blockchain a salad of transactions that are extremely difficult to track. It is practically impossible to calculate the sender and receiver of a specific transaction.
🔗 DASH #security depends on the owners of the system nodes (#masternodes). This problem was solved by redistributing the mining commission. When a new block of records appears in the blockchain, the commission is divided into three parts. 45% goes to miners, 45% goes to master nodes and another 10% goes to the cryptocurrency insurance fund.
🔗 Masternode owners also make decisions about the future of #DASH. This saves cryptocurrency from the dictates of miners and maintains the unity of the community of developers and users of cryptocurrency.
🔗 Also, PYRK uses PrivateSend and InstantSend originally developed by DASH. #PrivateSend is a term used to describe both mixing technology and Dash's private transactions. #InstantSend uses a masternode network to capture transaction inputs for an additional fee, and this makes the transaction instantly secure. PYRK Instant Transactions utilize Masternode quorums, users are able to send and receive instant irreversible transactions.

A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.
