#Reddcoin ($RDD) Core Wallet Release 3.0.1 - PosV v2 SuperMajority Consensus Upgrade at 45.6% - Required Upgrade

Reddcoin (RDD) Core Wallet v3.0.1 - January 09, 2020
Version 3.0.1 is the official release version of Reddcoin Core. It is available for download at Reddcoin Core's Github repository here: https://github.com/reddcoin-project/reddcoin/releases/tag/v3.0.1
This release features PoSV v2.supermajority activation and new staking ruleset (and minor misc fixes). v3.0.1 is still not yet MacOS Catalina compatible. We are still working and should have that fix issued very soon. Sincere apologies to our Mac-using ReddHeads.
It is particularly important that all users upgrade, as once PoSV v2 is enforced, version 4 blocks will be rejected from the network entirely.
Therefore v3.0.1 is a "strongly recommended" update for all users. Note: If you have already installed v3.0.0, this upgrade is not required. If you have not yet upgraded from v2.0.x or earlier, this is a REQUIRED upgrade. Please install the newest version v3.0.1 to avoid losing functionality during supermajority activation of PoSV v2.
Reddcoin Core version 3.0.1 is now available from: https://github.com/reddcoin-project/reddcoin/releases Release Notes are available here and replicated below in this announcement: https://github.com/reddcoin-project/reddcoin/blob/mastedoc/release-notes.md
This is a new major version release of Reddcoin.
Previously, the original and subsequent versions of Reddcoin were taken from a fork of the Litecoin code base.
With the release of Reddcoin V2.0.0, the code was based directly from a fork of Bitcoin. This allows for better source control and feature implementation from upstream changes into the future
With the release of Reddcoin V3.0.0, the PoSV stake reward has been improved to allow for a target 5% network growth, in process re-incentivizing individual network stakers and providing for integrated dev support.
Upgrading to this release is strongly recommended and required for continued operation. Once a supermajority of 90% is reached, old wallets will no longer accept the new v5 blocks.
Please report bugs using the issue tracker at github:
https://github.com/reddcoin-project/reddcoin/issues
How to Upgrade
If you are running an older version of Reddcoin, shut it down. Wait until it has completely shut down (which may take a few minutes for older versions). Run the installer (on Windows) or just copy over /Applications/Reddcoin-Qt (on Mac) or reddcoind/reddcoin-qt (on Linux).
Start wallet. All done!
Reddcoin v3.0.0 introduced an updated PoSV method to better distribute staking rewards and target a overall 5% network growth. Staking and relay policy enhancements 
To implement PoSV v2, Reddcoin Core's block templates are now for version 5 blocks only. When PoSV v2 consensus (Supermajority 9000/10000) is reached, only v5 blocks will be accepted by the network.This equates to approximately 90% of blocks being generated over 1 week period. Status at any time may be viewed in node debug.log

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Groestlcoin EasyVanity 2020

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:

If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

[Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

This tutorial has been updated: https://www.reddit.com/reddCoin/comments/a0wn1v/updated_staking_reddcoin_core_client_gui_wallet/.
   

Intro

I want to stake Reddcoins on my Raspberry Pi, but there is no easy to install package for the Reddcoin Core client. I found some tutorials (mentioned at the bottom, under 'credits'), but I still struggled to get the result I wanted. It took some small adjustments, but I got the GUI Wallet of Reddcoin Core working on my Raspberry Pi Model 3B. See the steps below. :).

Even though Raspbian is the primary OS for the Raspberry Pi, it seems that it's not possible to build and compile the Reddcoin wallet software for Raspbian Stretch. However, I got the wallet compiled using Ubuntu MATE.

Start Here for Much Wallet WOW!

EDIT 2017-02-10: A word about Nodes

There is a discussion about nodes that came up today, where it seems I'm discouraging people from running the full QT/Core client. Yes and No. What I'm trying to make sure people understand is how things work, and that it is NOT mandatory to run a client in order to use Dogecoins (and yes, I realise that browser-based tools like coinb.in and wallet sweepers are 'clients' by strict definition).
That said, more nodes is absolutely a good thing for the network. Preferrably full nodes. How do you run a full node? Just run Core/QT and open up Port 22556 on your router so it can connect to more than 8 peers. What will it cost you? You need your machine to be on 24/7/365, you need enough storage for the full blockchain (currently about 20Gb. Bitcoin is over 120Gb) and enough bandwidth to keep it in sync and share blocks with peers. A couple of Gb a month, most likely. This is best done with a desktop on a wired broadband link. Or maybe a hosted VM in the cloud. :)

EDIT 2017-01-09: Wallets WITHOUT Clients

Since I started helping people on /BitcoinBeginners, I'm getting a lot of questions about how to use wallets without running clients or trusting third parties. So here are a couple of resources that will make that possible, and not just for Dogecoin:
Multi-Coin Wallet Generator Now supporting 129 currencies! Coinb.in Start by setting the currency, found in the gear wheel in the Broadcast tab. Dogecoin Wallet Sweeper Redeem 'paper' wallets containing up to about 100 UTXOs. Bitinfo Charts My favourite block explorer, handles a bunch of cryptos.
Using these resources, it is possible to hold, receive and spend coins in various currencies, without having to run QT or a 'lite' client. You can also download and run the pages on your own device.

EDIT 2016-11-23: SEMANTICS about MINING! :P

Even though there is already a section on mining below, it has been suggested given the huge number of posts on the subject that this needs to be made clearer. Since people get their panties in a twist over the word 'dead', lets change that...

MINING IS DEAD!

MINING DOGECOIN IS UNPROFITABLE!

Put simply, there is no way to mine Dogecoin and make a profit because of the massive hashpower provided by industrial-scale Litecoin miners. Mining Doge directly stopped being viable when our hashrate exploded with the introduction of AuxPoW. Mining with CPU's and GPU's died when ASICs were introduced. And mining with a laptop WILL kill your laptop and cost you a fortune to repair or replace. Mining Litecoin with an exchange that also mines Doge and others will earn less than the electricity consumed, and you won't recover your costs. Probably ever, but certainly not in any reasonable time.
Mining other currencies may be a thing, but that's beyond our scope here. This is /Dogecoin, not /GetRichMiningCryptos after all. If you want to mine the newest scamcoin for fun and profit, look elsewhere for advice. :/
Oh, and most important:

READ BEFORE YOU POST!

At any given time, there are half a dozen posts on the frontpage just like the one you're about to write, where the answers have already been given. Read them. Don't make people waste their time repeating themselves because you were too lazy to bother reading stuff. :P
So there I was, having a quiet Sundy arvo bludge, as you do, when 42points turned up on Facebook and asked me to write a new sticky post for /dogecoin. Why would he do this, when he should be having a bludge himself, I hear you ask? Well, seems he was doing exactly that, and wanted to fob off the work he’s too slack to do himself. ;) Ah well, being a sucker for punishment, I’ll grudgingly oblige I guess.
OK, first things first.

From peoplma
I was wondering if you could add just a couple things. A link to the coinomi android wallet, it's probably the best one out there. And a sentence somewhere along the lines of "if you need help with any dogecoin software you are welcome to make a post, but PLEASE include your OS, version number of the client, and any relevant transaction IDs that you are willing to share" if you can fit that in somewhere.
Also, if you want to link to Prohashing, I'm pretty sure it's the only Scrypt mining pool that will actually pay out in doge. The others I know of pay out in litecoin or bitcoin. And it's a profit switching multipool, so gives a better return than just mining ltc/doge.
And there's these two wiki articles I thought would be helpful to link /dogecoin/wiki/technical for those technically minded newbies or intermediate users who want to dig a little deeper. And maybe a link to /dogecoin/wiki/dogecoincoreguide next to the link for dogecoin core.
From pts2002
Finally a proper sticky post! Here's some other stuff you could add:
zpool.ca mining pool - You can get paid in pretty much any coin, and you can mine in multiple algos (currently mining lyra2v2 with my GPU). Doing about 500Ð/day
shapeshift.io exchange - My favourite exchange, quick and easy. No registration required!
Also, you should add some blockchain explorers!
chain.so - Support for bitcoin, litecoin and doge.
dogechain.info - Official blockchain explorer. Includes a wallet (already mentioned). Live update currently not working (?)
EDIT: Here's another thing I found!
preev.com currency value calculator - Easy way to check the value of your dogecoins (or bitcoins, or litecoins, or peercoins)!

RaiBlocks AMA Summary!

I posted this under /cryptocurrency and /cryptomarkets as well! Might be less useful under this subreddit... but I'm using it for purposes of helping people become aware of this coin.
Summation of RaiBlocks lead developer AMA. I'm very excited about this coin, and if you're asking why I did this...I'm trying out my AMA consolidating script that I wrote for fun :) I'm interested in seeing what people think about this coin! You can read the responses directly from this link: https://www.reddit.com/RaiBlocks/comments/7ko5l7/colin_lemahieu_founder_and_lead_developer_of/
 
What are your top priorities atm? Both in developing areas itself and in terms of integration?
 
The top priorities right now are:
These basically need to happen in a sequence because each item isn't useful unless the previous one is complete.
 
 
Do you have any plans to have your source code peer reviewed? By peer review I mean sending your source code down to MIT for testing and review.
Where do you see Raiblocks 5-10 years from now? (For instance do you envision people using a Raiblocks mobile phone app to transfer value between each other, or buy stuff at the store?
 
We definitely need peer and code reviews and we're open to anyone doing this. We have ideas for people in universities that want to analyze the whitepaper or code so we'll see what comes of that. In my opinion code security guarantees can only be given with (eyes * time) and we need both.
I'd like to see RaiBlocks adopted as an internet RFC and basically become an ubiquitous background technology like http. I think you're probably right and a mobile app would be the most user-friendly way to do this so people don't need to carry around extra cards in their wallet etc.
 
 
Is there a list of the team readily available? Are there firm plans to expand, and if so, in which directions?
The roadmap indicated a website redesign scheduled for November 2017. Is there an update?
 
We have about 12 people in the core team; about half are code and half are business developers. On the redesigned website we're going to include bios for sure, no one in our team is anonymous. I think we have pretty good coverage of what we need right now, we could always use more people capable of contributing to the core code.
The website design is well underway, we wanted to streamline and add some more things to it so it took longer than originally estimated. It'll looking like after the new year we'll have it ready.
 
 
Would you ever consider renaming the coin to simply "Rai" or any other simplified form other than RaiBlocks?
2. What marketing strategy do you think will push XRB forward from now on as a fully working product. Instant and free, the green coin, "it just works" coin, etc?
3. Regarding security, is "quantum-proofing" a big concern at the moment and how do you guys plan to approach this when the time comes. And how possible would it be for bad actors to successfully implement a 51% attack.
 
  1. Yea there are a few difficulties people have pointed out with our name. People don't know if it's "ray" or "rye". "Blocks" doesn't have a meaning to a lot of people and the name reference might be too esoteric to be meaningful. I'm not prideful so I'm not stuck on a particular name, we'll take a look at what our marketing and business developers say peoples' impressions are and if they have any naming recommendations.
  2. Our marketing strategy is to focus on complete simplicity. Instant and free resonates with enthusiasts and mass adoption will only come when using xrb is absolutely the same experience as using a banking or other payment app. People aren't going to tolerate jargon or confusing workflows when sending or receiving payments.
  3. Quantum computing is going to be an amazing leap for humanity but it's also going to cause a lot of flux in cryptography. The plan I see is the similar to what I did in selecting the cryptographic algorithms we're using right now: look for leaders in academia and industry that have proven implementations and use those as they recommend migration based on computing capability. Quantum vulnerabilities can be an issue in the future but a vulnerable implementation would be an issue right now.
 
 
Hi Colin, lately XRB has been getting frequently compared to and contrasted with Iota. I was hoping that you could give us your thoughts on the differences between the two and what your general vision for the future of Raiblocks is.
 
It's flattering to be compared to IOTA, they have a very talented team building ambitious technology. When looking at design goals I think one thing we're not attempting to approach is transferring a data payload, we're only looking to be a transfer of value.
There are lots of ideas and technology to be developed in the cryptocurrency space and I want RaiBlocks to solve one section of that industry: the transfer of value. I think the best success would be if RaiBlocks was adopted as the global standard for this and crypto efforts could move to non-value-transfer use-cases.
 
 
Do you see XRB becoming the new payment method for commerce. As in, buying coffee, groceries, etc? Do you have plans for combating the HODL mentality so this currency can actually be used in the future of buying and selling?
 
Being a direct transactional payment method is our goal and we're trying to build software that's accessible to everyone to make that happen. I see holding as a speculative tactic anticipating future increases and you're right, it's not in line with day-to-day transactions. I think as market cap levels off to a more consistent value the reason for holding and speculating goes away and people can instead focus on using it as a value exchange.
 
 
Are you planning to expand the RaiBlocks team over the next 12 months? If so, what types of positions are you hoping to fill?
 
Right now we have about 12 people, half core and half business developers. I think this count is good for working on what we're doing right now which is getting wallets and exchanges worked on. Ideally people outside our team will start developing technology around xrb taking advantage of the network effect to build more technology faster than we could internally. That being said we're going to look in a few months to see if there's anything out there people aren't developing that should be and we'll see what people we need to make it happen.
 
 
At what point did you make the decision to make RaiBlocks your full time job? What was the decision making process like?
 
It was after the week where the core team met here in Austin to brainstorm our next steps. I saw how much enthusiasm there was from crypto-veterans with having a working system capable of being scaled up to what's needed for massive adoption and it seemed the risk needed to be taken.
It was hard decision to make, working in the crypto and finance is rough and I like using my leisure time to work on inventions. Of all the projects ideas I have this one seemed to have a high chance of success and the benefits of having a working, decentralized currency would be huge.
 
 
Hi Colin, what prevents great cryptos like XRB from being listed on bigger exchanges?
 
It's good to understand where the biggest headaches for exchanges lie: support tickets, operations, and development. If a technology is different from what they already have, that takes development time. If the software is new and not widely run, that's potential operations time to fix it which results in support tickets and community backlash. Adding BitCoin clones or Ethereum ICO coins is easy because they don't have these associated risks or costs.
 
 
What can the average RaiBlocks-Fan do to help XRB getting adopted / growing / expanding?
 
I think the best thing an average fan could do is word of mouth and telling people about RaiBlocks. More people being aware of it means there's the possibility someone who's never heard of it before would be interested in contributing as a vendor, developer, exchange etc.
Good advertising or marketing will never be able to reach everyone as well as someone reaching out within their own network.
 
 
Ray or Rye?
 
Ray hehe. It comes from https://en.wikipedia.org/wiki/Rai_stones Lots of people don't know the answer though >_<
 
 
Are you looking at incorperating a datamarket like iota in the future? Given the speed of the network a data exchange for highly accurate sensors could be a game changer.
Further more, are there any plans to increase the Dev team in the future? I read on the FAQ you'd like RaiBlocks to be somewhat of a protocol which is a huge ambition. A Dev from say the Mozilla foundation or other could further cement this ambitious project.
 
Transmitting data payloads is something we probably won't pursue. The concern is adding more features like this could cause us to make decisions that compromise the primary focus points of low-cost and speed for transferring value.
We can add people to the dev team though I think we'll get the most traction by teaching teams in these other organization how to use RaiBlocks so they can be the experts on the subject in their companies.
 
 
Does the actual RaiBlocks version require "Each node in the network must be aware of all transactions as they occur" part? This was in the old white paper and is asked here:
https://www.reddit.com/RaiBlocks/comments/7ksl81/some_questions_regarding_raiblocks_consensus/?st=jbdmgagc&sh=d1c93cca
 
If a node wants to independently know the balances of all accounts in the system, it must at a minimum have storage to hold accounts and all their balances. In order to know all balances it must either listen to transactions as they're happening or bootstrap from someone else to catch up as what happens on startup.
 
 
There is no incentive to run nodes. Some people will do it because it is cheap as fuck (as I read an raspberry pie can run it). But I think not many people will do it.
1. How important are the nodes in terms of further scaling?
2. On which network conditions where the 7000 transactions met?
3. What happens if the transactions per day tenfolds but the nodes don't?
4. How much better will Rai scale if someone sets up, lets say, 100 nodes with awesome hardware and network?
5. How many nodes could be enough for visa level scaling?
6. Which further improvements can be made for Rai IF there needs to be other improvements than setting up new nodes? Are there other concepts like 2nd layer solutions planned?
7. How will Rai defend network attacks?
I know there is an PoW part. But since there a also large attacks on high cap coins on which people invest millions of $ to congest a network..Is it possible that the Rai network will be unusable for several days because of this?
 
I think the out-of-protocol incentives to running a node are under-referenced yet I see them as the primary driving factor for participating as a whole. Node rewards come at the expense of other network participants and in this closed loop the incentives aren't enough to keep a cryptocurrency alive. Long-term there needs to be a system-level comparative advantage to what people are already using for a transfer of value. If someone is using xrb and it saves them hundreds or thousands of dollars per month in fees and customer irritation in delayed payments, they have a direct monetary incentive to using xrb and a monetary incentive in the health of the system.
1) More nodes provides transaction and bootstrapping redundancy. More representatives provides decentralization.
2) The 7k TPS was a profile how fast commodity hardware could eat transactions. All of the real-world limits are going to be something hardware related, either bandwidth, IO, or CPU.
3) The scaling is more related to the hardware the nodes are using rather than the node count. If there was 10x increase in transactions it would use 10x the bandwidth and IO as nodes observe transactions happening.
4) If someone made 100 representative nodes the network would be far more decentralized though the tx throughput would be unchanged since that's a per-node requirement.
5) Scaling to Visa will have high bandwidth and IO requirements on representatives associated with doing 10k IOPS. Datacenter and business class hardware will have to be enough to handle the load.
6) Second layer solutions are always an option and I think a lot of people will use them for fraud protection and insurance. Our primary focus is to make the 1st layer as efficient and high speed as possible so a 2nd layer isn't needed for daily transactions.
7) Defending against network attacks will be an ongoing thing, people like breaking the network for lulz or monetary gain i.e. competing cryptos. If there are attacks we haven't defended against or considered it'll be a matter of getting capable people to fix issues.
 
 
Are you open to changes to the name? (Rai)
What are your plans with regards to marketing?
 
I'm open to it, people get confused on ray/rye pronunciation, not the greatest first impression.
As far as timing I think marketing works best after a more user friendly wallet and integration in to more exchanges otherwise we're sending traffic to something people can't use. We're going to start by focusing on the initial adopters which will likely be enthusiasts and going forward work on the next set of users that aren't enthusiasts but want to drive savings for their business through lower payment processing costs.
 
 
A recent tweet(https://twitter.com/VitalikButerin/status/942961006614945792) from Vitalik Buterin. Could this be a case with testing the scalability of RaiBlocks as well and in reality we wouldn't come close to 7000tx/s?
 
I think he's definitely right, a lot of the TPS numbers are synthetic benchmarks usually on one system. The biggest thing hindering TPS are protocol-specific limits like hard caps or high contention design. The next biggest thing will be bandwidth and then disk IO. Some of these limits can be improved by profiling and fixing code instead of actual limits in the hardware.
We want to get better, real world numbers but our general opinion is that the RaiBlocks protocol is going to be limited by hardware, rather than design.
 
 
Are you planning to add a fiat gateway to the main website and mobile wallet?
 
If we can make it happen for sure, that seems like a very user-focused feature people would want.
The difficulty at least in the US is the money-transmitter licenses which are hard to obtain. More than likely if this functionality was added it'd be a partnership with an established financial company that has procedures in place to operate within countries' regulations.
 
 
I saw a post on /iota that claims that their quantum resistance is a main benefit over raiblocks. Can you go into detail about this? explain any plans you have to let XRB persevere through upcoming quatum revolution?
 
I think everyone with cryptography in their programs is keeping an eye on quantum cryptography because we're all in the same boat. I don't have cryptanalysis credentials so I didn't feel comfortable building an implementation and instead chose to use one off-the-shelf from someone with assuring credentials.
There are some big companies that have made small mistakes that blow up the usefulness of the entire algorithm, it's incredibly easy to do. https://arstechnica.com/gaming/2010/12/ps3-hacked-through-poor-implementation-of-cryptography/
 
 
Hello Colin, is any security audit to the source code planned?
 
We don't have one contracted though both internally and externally this is an important thing people want completed.
 
 
Do you have plans to radically change the interface of the desktop wallet, and to develop a universal, cross-platform, clean and simple UX design for the wallet? This will be huge for mass adoption in my humble opinion
 
I completely agree, we do plan on completely redoing the desktop wallet, both from a UX standpoint and maintainability so UI code doesn't need to be in C++. This could also remove out dependency on QT which is the least permissive license in the code right now.
I write code better than I design GUIs ;)
 
 
It seems like Raiblocks is aiming to be a true currency with it's lacking of transaction fees and fast confirmation times, which is great! If Raiblocks can add some kind of support for privacy then I think it got the whole picture figured out in terms of being "digital cash". Do you currently have any plans to implement privacy features into RaiBlocks?
If Raiblocks is unable to do this, it will still be a straight improvement over things like LTC which are currently being used as currency, but I don't think it will be able to become THE cryptocurrency without privacy features.
 
I love the concept of privacy in the network and it's a hard thing to do right. Any solution used would need to be compatible with our balance-weighted-voting method which means at least we'd have to know how much weight a representative has even if we're hiding actual account balances.
To be fully anonymous it would have to be hide accounts, amounts, endpoints, and also timing information; with advanced network analysis the timing is the hardest thing to hide. Hopefully some day we can figure out an efficient privacy solution though the immediate problem we can solve is making a transactional cryptocurrency so we're focusing on that.
 
 
Could you provide an analysis on the flaws of RaiBlocks? Is it in any way, shape, or form at a disadvantage compared to a blockchain based ledger like bitcoin? There has to be drawbacks, but I haven’t found any.
Do you plan on expanding the dev team and establishing a foundation? Also, how much money is in the development pool?
 
One drawback is to handle is our chain-per-account model and asynchronous updates it takes more code and design. This means instead of one top-block hash for everything there's one for each account. This gives us the power of wait-free asynchronous transactions at the cost of simplicity.
After we finish up things like the wallet, website, and exchange integration we'll be looking at seeing what dev resources we need to build tech if no one else is already working on a particular thing. We have about 6 million XRB right now so we've made the existing dev funds go a long way. If something expensive to build came along and dev funds wouldn't cut it we could look at some sort of external funding.
 
 
How big of a problem is PoW for exchanges and what are potential solutions?
 
Considering how much exchanges stand to make through commission I don't see the cost as a barrier, it's just an abnormal technology request compared to other cryptocurrencies.
We're working on providing a service exchanges can use in the interim until they set up their own infrastructure to generate the work. Other options are containers people can use on cloud services to get the infrastructure they need until they want to invest in their own.
 
 
It's my understanding that since everything works asynchronously, in the case of double spending there is a chance a merchant would receive the block that would be later invalidated and have it shown in it's wallet, even if a little later (1 minute?) the amount would correct when the delegates vote that block invalid. Is there any mechanism to avoid this? Maybe tag the transactions in the wallet as "confirming" and then "confirmed" after that minute? Is there actually any certain way for a wallet to know, in a deterministic/programable way, at what moment a transaction is 100% legit? (for example if the delegates are DoS'ed I guess that minute could be much longer). I know this is an improbable case, but still...
 
Yea you're hitting a good point, the consensus algorithm in the node is designed to wait for the incoming transaction to settle before accepting it in to the local chain for the exact reason you listed, if their transaction were to be rolled back the local account would be rolled back as well.
We can trend the current weight of all representatives that are online and voting and make sure we have >50% of the vote weight accounted for before considering it settled.
 
 
Hey Colin, will you eventually have support for a Trezor or other hard wallet?
 
Yea we'll definitely work with companies like Trezor that are interested in being a hardware wallet for xrb. It's just a matter of making sure they support the signing algorithms and integrating with their API.
 
EDIT: I'm getting a lot of messages asking me how to buy XRB. I used this guide which was very helpful: https://www.reddit.com/RaiBlocks/comments/7i0co0/the_definitive_guide_to_buying_and_storing/
In short -- buy BTC on coinbase, open up an account on bitgrail, transfer that BTC from coinbase to bitgrail, then trade your BTC for XRB. It's a pain right now because it's such a new coin, but soon it will be listed on more exchanges, and hopefully on things like shapeshift/changelly. After that it will be much easier... but until then, the inconvenience is what we have to pay in order to get into XRB while its still early.
EDIT: BAD SCRIPT, BAD!

[ELI5] Extracting Privkeys from QT/Core

We have a constant stream of people coming back after abandoning Dogecoin and the sub in 2014 when the price fell. These people all have old versions of QT and are now basically trying to recover their coins, presumably to cash out and abandon us again. This is causing strain for the network, as far more people are trying to leech blocks than seed them.
The thing is, none of this is necessary. Especially if you're just going to dump coins. With resources such as https://coinb.in/#settings all you need are your private keys, and you can create, sign and broadcast transactions yourself. No client required, let alone one as resource-hungry as QT.

"So, how do I get my keys?"

First of all, lets talk about data management. The overwhelming majority of coins are not lost through theft, especially direct theft of wallets (as distinct from wholesale thefts/scams/implosions like Moolah, GAW, MtGox, Cryptsy, and even our own beloved Dogetipbot). Most coins are lost because people forget about their wallets and do silly things like reformat hard drives, lose passwords and so on.
So, everyone should have a wallet list. Here is a sample bit of HTML that gives you a page with two columns of wallets, one for local wallets you would withdraw coins to, the other the third-party wallets you would deposit coins to third parties through (do note that many services use temporary addresses generated for deposits which expire after 24h or so). A page like this is how I manage my 100+ wallets, and I have copies on my network and hidden online. Such a page makes it easy to at least keep track of all your wallets, for a trivial amount of work to set up.
 
 Sample - Twitter Fr DFXXz9gq3WkgJaHn9tXRChMhFQcwm4Y251 To DByYgzd4ec5Ku9vPag8XqoBfyRpsoj8Xs3 @TipDoge Sample - Backslash Fr DSDyv83VC1QtEnmJ4ATKFn5Sw3iC12VLmX To D9MsxSyJe5Mq7fWFRpC7zQQt1gexHccN4w Backslash To DJ3GL68kw8vh99RvxnEmQKE8A3cWRoEEqo Backslash Faucet Sample - Block.io To DE5QamzWVnxK2HmCS61cUsrn9iwgTArunU Block.io 

"OK, great, so now I have a list of my wallets. Now what?"

Now you're going to need the private keys for each of those wallets. Obviously you're not going to store these in a public place though. So you will need a separate file, which can just be plain text. Copy each of those addresses into it.
Now go ahead and fire up QT. If you haven't synced it in 3 years, its going to take forever, but that doesn't matter. You don't actually need the blockchain for this, so you don't have to wait for it to catch up.
Open up the console which is in the Help menu. Then give the command dumpprivkey with the wallet address you want the key to. Then use the up-arrow key to bring that command back, replace the address with the next one, and keep going until you have them all.
It will look something like this:
 13:05:18 Welcome to the Dogecoin RPC console. Use up and down arrows to navigate history, and Ctrl-L to clear screen. Type help for an overview of available commands. 13:11:06 dumpprivkey D9xDcRthB6XP4vRGqiyKdDfVJ7CWhYuBBi 13:11:06 6KEcssuq1wWUrFVmMF8yDxHuAdQMiRezz53zDxADLmyoXnix7iM 13:12:00 dumpprivkey DUDARNrGHVTFcCgriwRWgDQJPKDuDQr9jg 13:12:00 6JNk6NNFZcr49fbsD2jcTfTxFLjJKq9DHQ5JU8CYeZ2Cz6JdKMY 13:12:25 dumpprivkey DG6xnwCT6BXePaySqU85XocobZmhbJczQH 13:12:25 6JNXFv95Mp9SzehHw9jojjdxHRNPeh77qCsRbaNwJZMp9MKCAu3 
Yes, those are real wallets. But don't bother trying to steal my coins, I just generated them on https://walletgenerator.net/ and they're empty.
That's basically it. All you need to do is add some descriptions of what the wallets are, pretty up the format to your liking, and save copies in multiple, secure places, including printed out.

Remember, if you lose your keys, OR someone else sees them, you lose your coins!

If those were my real wallets above, you could use the keys and spend my coins. So obviously, don't let anyone else, especially annoying little brothers, get their grubby hands on them. But also make sure they can be discovered if anything happens to you. That's why the printed copies... nobody is going to go trolling through your porn or warez collection on the offchance there's something valuable in there. But they will look in your safe or wherever you store other important documents. Just be sure to leave a note as to what they are and how to use them. Remember the woman who came here a couple years ago who had found a USB stick with 110 BTC in a locked wallet.dat on it from her dead husband? I sometimes wonder if she ever got the money. Don't be her. Or him.

"OK, great. Now I have my keys. What now?"

Well, you can spend coins using https://coinb.in/#settings from any wallet you have the keys to. First step is to choose the network. Dogecoin (mainnet) obviously. Then go to Transaction in the +New menu. Enter your address and hit the Load button. It will pull in the first 100 transactions. Now enter the address to pay, and the amount.
Note the Transaction Fee box!
You want this amount to be zero. Depending on whether you're moving coins to another of your wallets to consolidate them (a very good idea.. go read the UTXO ELI5, which you will find a couple pages into https://www.reddit.com/dogecoin/comments/4yts6h/start_here_for_much_wallet_wow/ - Yes, I'm going to make you work for it, cos there's tons of useful stuff there you need to know), or paying someone else, you may want to select which inputs to use.
Once you're happy with the transaction, go ahead and submit it. You will now get a block of text, which is the raw, unsigned transaction. Copy this. Go to the Sign tab. Paste it. Add your private key and Submit to sign it.
After a little bit, you will get a signed transaction. Copy it. Go to the Broadcast tab, paste it and hit Submit.
That's it. It should go into the next block in a minute or two. Yes, even without paying a mining fee. Our network is so lightly loaded that there are no contention issues like the Bitcoin people have to put up with.

"That's it? So why do I need QT?"

You don't. The process above is all that's involved in spending coins. Everything else is window dressing. So there is no need to run QT, or any other client. Oh, and since you can download the site and run it locally (mostly offline), there is no security issue beyond the usual keyloggers/spyware that can compromise anything. And by knowing how to do this, you are much better protected from accidental loss than someone who blindly trusts black boxes they don't understand.
Oh, one final thing... if you really want to help the network by seeding rather than leeching, go ahead and run a full node. Instructions are in that link above. AND you may want to help seed the bootstrap file torrent from a couple of days ago. Just because YOU don't need it, doesn't mean others don't, right?

RaiBlocks AMA Summation!

Summation of RaiBlocks lead developer AMA. I'm very excited about this coin, and if you're asking why I did this...I'm trying out my AMA consolidating script that I wrote for fun :) I'm interested in seeing what people think about this coin! You can read the responses directly from this link: https://www.reddit.com/RaiBlocks/comments/7ko5l7/colin_lemahieu_founder_and_lead_developer_of/
 
What are your top priorities atm? Both in developing areas itself and in terms of integration?
 
The top priorities right now are:
These basically need to happen in a sequence because each item isn't useful unless the previous one is complete.
 
 
Do you have any plans to have your source code peer reviewed? By peer review I mean sending your source code down to MIT for testing and review.
Where do you see Raiblocks 5-10 years from now? (For instance do you envision people using a Raiblocks mobile phone app to transfer value between each other, or buy stuff at the store?
 
We definitely need peer and code reviews and we're open to anyone doing this. We have ideas for people in universities that want to analyze the whitepaper or code so we'll see what comes of that. In my opinion code security guarantees can only be given with (eyes * time) and we need both.
I'd like to see RaiBlocks adopted as an internet RFC and basically become an ubiquitous background technology like http. I think you're probably right and a mobile app would be the most user-friendly way to do this so people don't need to carry around extra cards in their wallet etc.
 
 
Is there a list of the team readily available? Are there firm plans to expand, and if so, in which directions?
The roadmap indicated a website redesign scheduled for November 2017. Is there an update?
 
We have about 12 people in the core team; about half are code and half are business developers. On the redesigned website we're going to include bios for sure, no one in our team is anonymous. I think we have pretty good coverage of what we need right now, we could always use more people capable of contributing to the core code.
The website design is well underway, we wanted to streamline and add some more things to it so it took longer than originally estimated. It'll looking like after the new year we'll have it ready.
 
 
Would you ever consider renaming the coin to simply "Rai" or any other simplified form other than RaiBlocks?
2. What marketing strategy do you think will push XRB forward from now on as a fully working product. Instant and free, the green coin, "it just works" coin, etc?
3. Regarding security, is "quantum-proofing" a big concern at the moment and how do you guys plan to approach this when the time comes. And how possible would it be for bad actors to successfully implement a 51% attack.
 
  1. Yea there are a few difficulties people have pointed out with our name. People don't know if it's "ray" or "rye". "Blocks" doesn't have a meaning to a lot of people and the name reference might be too esoteric to be meaningful. I'm not prideful so I'm not stuck on a particular name, we'll take a look at what our marketing and business developers say peoples' impressions are and if they have any naming recommendations.
  2. Our marketing strategy is to focus on complete simplicity. Instant and free resonates with enthusiasts and mass adoption will only come when using xrb is absolutely the same experience as using a banking or other payment app. People aren't going to tolerate jargon or confusing workflows when sending or receiving payments.
  3. Quantum computing is going to be an amazing leap for humanity but it's also going to cause a lot of flux in cryptography. The plan I see is the similar to what I did in selecting the cryptographic algorithms we're using right now: look for leaders in academia and industry that have proven implementations and use those as they recommend migration based on computing capability. Quantum vulnerabilities can be an issue in the future but a vulnerable implementation would be an issue right now.
 
 
Hi Colin, lately XRB has been getting frequently compared to and contrasted with Iota. I was hoping that you could give us your thoughts on the differences between the two and what your general vision for the future of Raiblocks is.
 
It's flattering to be compared to IOTA, they have a very talented team building ambitious technology. When looking at design goals I think one thing we're not attempting to approach is transferring a data payload, we're only looking to be a transfer of value.
There are lots of ideas and technology to be developed in the cryptocurrency space and I want RaiBlocks to solve one section of that industry: the transfer of value. I think the best success would be if RaiBlocks was adopted as the global standard for this and crypto efforts could move to non-value-transfer use-cases.
 
 
Do you see XRB becoming the new payment method for commerce. As in, buying coffee, groceries, etc? Do you have plans for combating the HODL mentality so this currency can actually be used in the future of buying and selling?
 
Being a direct transactional payment method is our goal and we're trying to build software that's accessible to everyone to make that happen. I see holding as a speculative tactic anticipating future increases and you're right, it's not in line with day-to-day transactions. I think as market cap levels off to a more consistent value the reason for holding and speculating goes away and people can instead focus on using it as a value exchange.
 
 
Are you planning to expand the RaiBlocks team over the next 12 months? If so, what types of positions are you hoping to fill?
 
Right now we have about 12 people, half core and half business developers. I think this count is good for working on what we're doing right now which is getting wallets and exchanges worked on. Ideally people outside our team will start developing technology around xrb taking advantage of the network effect to build more technology faster than we could internally. That being said we're going to look in a few months to see if there's anything out there people aren't developing that should be and we'll see what people we need to make it happen.
 
 
At what point did you make the decision to make RaiBlocks your full time job? What was the decision making process like?
 
It was after the week where the core team met here in Austin to brainstorm our next steps. I saw how much enthusiasm there was from crypto-veterans with having a working system capable of being scaled up to what's needed for massive adoption and it seemed the risk needed to be taken.
It was hard decision to make, working in the crypto and finance is rough and I like using my leisure time to work on inventions. Of all the projects ideas I have this one seemed to have a high chance of success and the benefits of having a working, decentralized currency would be huge.
 
 
Hi Colin, what prevents great cryptos like XRB from being listed on bigger exchanges?
 
It's good to understand where the biggest headaches for exchanges lie: support tickets, operations, and development. If a technology is different from what they already have, that takes development time. If the software is new and not widely run, that's potential operations time to fix it which results in support tickets and community backlash. Adding BitCoin clones or Ethereum ICO coins is easy because they don't have these associated risks or costs.
 
 
What can the average RaiBlocks-Fan do to help XRB getting adopted / growing / expanding?
 
I think the best thing an average fan could do is word of mouth and telling people about RaiBlocks. More people being aware of it means there's the possibility someone who's never heard of it before would be interested in contributing as a vendor, developer, exchange etc.
Good advertising or marketing will never be able to reach everyone as well as someone reaching out within their own network.
 
 
Ray or Rye?
 
Ray hehe. It comes from https://en.wikipedia.org/wiki/Rai_stones Lots of people don't know the answer though >_<
 
 
Are you looking at incorperating a datamarket like iota in the future? Given the speed of the network a data exchange for highly accurate sensors could be a game changer.
Further more, are there any plans to increase the Dev team in the future? I read on the FAQ you'd like RaiBlocks to be somewhat of a protocol which is a huge ambition. A Dev from say the Mozilla foundation or other could further cement this ambitious project.
 
Transmitting data payloads is something we probably won't pursue. The concern is adding more features like this could cause us to make decisions that compromise the primary focus points of low-cost and speed for transferring value.
We can add people to the dev team though I think we'll get the most traction by teaching teams in these other organization how to use RaiBlocks so they can be the experts on the subject in their companies.
 
 
Does the actual RaiBlocks version require "Each node in the network must be aware of all transactions as they occur" part? This was in the old white paper and is asked here:
https://www.reddit.com/RaiBlocks/comments/7ksl81/some_questions_regarding_raiblocks_consensus/?st=jbdmgagc&sh=d1c93cca
 
If a node wants to independently know the balances of all accounts in the system, it must at a minimum have storage to hold accounts and all their balances. In order to know all balances it must either listen to transactions as they're happening or bootstrap from someone else to catch up as what happens on startup.
 
 
There is no incentive to run nodes. Some people will do it because it is cheap as fuck (as I read an raspberry pie can run it). But I think not many people will do it.
1. How important are the nodes in terms of further scaling?
2. On which network conditions where the 7000 transactions met?
3. What happens if the transactions per day tenfolds but the nodes don't?
4. How much better will Rai scale if someone sets up, lets say, 100 nodes with awesome hardware and network?
5. How many nodes could be enough for visa level scaling?
6. Which further improvements can be made for Rai IF there needs to be other improvements than setting up new nodes? Are there other concepts like 2nd layer solutions planned?
7. How will Rai defend network attacks?
I know there is an PoW part. But since there a also large attacks on high cap coins on which people invest millions of $ to congest a network..Is it possible that the Rai network will be unusable for several days because of this?
 
I think the out-of-protocol incentives to running a node are under-referenced yet I see them as the primary driving factor for participating as a whole. Node rewards come at the expense of other network participants and in this closed loop the incentives aren't enough to keep a cryptocurrency alive. Long-term there needs to be a system-level comparative advantage to what people are already using for a transfer of value. If someone is using xrb and it saves them hundreds or thousands of dollars per month in fees and customer irritation in delayed payments, they have a direct monetary incentive to using xrb and a monetary incentive in the health of the system.
1) More nodes provides transaction and bootstrapping redundancy. More representatives provides decentralization.
2) The 7k TPS was a profile how fast commodity hardware could eat transactions. All of the real-world limits are going to be something hardware related, either bandwidth, IO, or CPU.
3) The scaling is more related to the hardware the nodes are using rather than the node count. If there was 10x increase in transactions it would use 10x the bandwidth and IO as nodes observe transactions happening.
4) If someone made 100 representative nodes the network would be far more decentralized though the tx throughput would be unchanged since that's a per-node requirement.
5) Scaling to Visa will have high bandwidth and IO requirements on representatives associated with doing 10k IOPS. Datacenter and business class hardware will have to be enough to handle the load.
6) Second layer solutions are always an option and I think a lot of people will use them for fraud protection and insurance. Our primary focus is to make the 1st layer as efficient and high speed as possible so a 2nd layer isn't needed for daily transactions.
7) Defending against network attacks will be an ongoing thing, people like breaking the network for lulz or monetary gain i.e. competing cryptos. If there are attacks we haven't defended against or considered it'll be a matter of getting capable people to fix issues.
 
 
Are you open to changes to the name? (Rai)
What are your plans with regards to marketing?
 
I'm open to it, people get confused on ray/rye pronunciation, not the greatest first impression.
As far as timing I think marketing works best after a more user friendly wallet and integration in to more exchanges otherwise we're sending traffic to something people can't use. We're going to start by focusing on the initial adopters which will likely be enthusiasts and going forward work on the next set of users that aren't enthusiasts but want to drive savings for their business through lower payment processing costs.
 
 
A recent tweet(https://twitter.com/VitalikButerin/status/942961006614945792) from Vitalik Buterin. Could this be a case with testing the scalability of RaiBlocks as well and in reality we wouldn't come close to 7000tx/s?
 
I think he's definitely right, a lot of the TPS numbers are synthetic benchmarks usually on one system. The biggest thing hindering TPS are protocol-specific limits like hard caps or high contention design. The next biggest thing will be bandwidth and then disk IO. Some of these limits can be improved by profiling and fixing code instead of actual limits in the hardware.
We want to get better, real world numbers but our general opinion is that the RaiBlocks protocol is going to be limited by hardware, rather than design.
 
 
Are you planning to add a fiat gateway to the main website and mobile wallet?
 
If we can make it happen for sure, that seems like a very user-focused feature people would want.
The difficulty at least in the US is the money-transmitter licenses which are hard to obtain. More than likely if this functionality was added it'd be a partnership with an established financial company that has procedures in place to operate within countries' regulations.
 
 
I saw a post on /iota that claims that their quantum resistance is a main benefit over raiblocks. Can you go into detail about this? explain any plans you have to let XRB persevere through upcoming quatum revolution?
 
I think everyone with cryptography in their programs is keeping an eye on quantum cryptography because we're all in the same boat. I don't have cryptanalysis credentials so I didn't feel comfortable building an implementation and instead chose to use one off-the-shelf from someone with assuring credentials.
There are some big companies that have made small mistakes that blow up the usefulness of the entire algorithm, it's incredibly easy to do. https://arstechnica.com/gaming/2010/12/ps3-hacked-through-poor-implementation-of-cryptography/
 
 
Hello Colin, is any security audit to the source code planned?
 
We don't have one contracted though both internally and externally this is an important thing people want completed.
 
 
Do you have plans to radically change the interface of the desktop wallet, and to develop a universal, cross-platform, clean and simple UX design for the wallet? This will be huge for mass adoption in my humble opinion
 
I completely agree, we do plan on completely redoing the desktop wallet, both from a UX standpoint and maintainability so UI code doesn't need to be in C++. This could also remove out dependency on QT which is the least permissive license in the code right now.
I write code better than I design GUIs ;)
 
 
It seems like Raiblocks is aiming to be a true currency with it's lacking of transaction fees and fast confirmation times, which is great! If Raiblocks can add some kind of support for privacy then I think it got the whole picture figured out in terms of being "digital cash". Do you currently have any plans to implement privacy features into RaiBlocks?
If Raiblocks is unable to do this, it will still be a straight improvement over things like LTC which are currently being used as currency, but I don't think it will be able to become THE cryptocurrency without privacy features.
 
I love the concept of privacy in the network and it's a hard thing to do right. Any solution used would need to be compatible with our balance-weighted-voting method which means at least we'd have to know how much weight a representative has even if we're hiding actual account balances.
To be fully anonymous it would have to be hide accounts, amounts, endpoints, and also timing information; with advanced network analysis the timing is the hardest thing to hide. Hopefully some day we can figure out an efficient privacy solution though the immediate problem we can solve is making a transactional cryptocurrency so we're focusing on that.
 
 
Could you provide an analysis on the flaws of RaiBlocks? Is it in any way, shape, or form at a disadvantage compared to a blockchain based ledger like bitcoin? There has to be drawbacks, but I haven’t found any.
Do you plan on expanding the dev team and establishing a foundation? Also, how much money is in the development pool?
 
One drawback is to handle is our chain-per-account model and asynchronous updates it takes more code and design. This means instead of one top-block hash for everything there's one for each account. This gives us the power of wait-free asynchronous transactions at the cost of simplicity.
After we finish up things like the wallet, website, and exchange integration we'll be looking at seeing what dev resources we need to build tech if no one else is already working on a particular thing. We have about 6 million XRB right now so we've made the existing dev funds go a long way. If something expensive to build came along and dev funds wouldn't cut it we could look at some sort of external funding.
 
 
How big of a problem is PoW for exchanges and what are potential solutions?
 
Considering how much exchanges stand to make through commission I don't see the cost as a barrier, it's just an abnormal technology request compared to other cryptocurrencies.
We're working on providing a service exchanges can use in the interim until they set up their own infrastructure to generate the work. Other options are containers people can use on cloud services to get the infrastructure they need until they want to invest in their own.
 
 
It's my understanding that since everything works asynchronously, in the case of double spending there is a chance a merchant would receive the block that would be later invalidated and have it shown in it's wallet, even if a little later (1 minute?) the amount would correct when the delegates vote that block invalid. Is there any mechanism to avoid this? Maybe tag the transactions in the wallet as "confirming" and then "confirmed" after that minute? Is there actually any certain way for a wallet to know, in a deterministic/programable way, at what moment a transaction is 100% legit? (for example if the delegates are DoS'ed I guess that minute could be much longer). I know this is an improbable case, but still...
 
Yea you're hitting a good point, the consensus algorithm in the node is designed to wait for the incoming transaction to settle before accepting it in to the local chain for the exact reason you listed, if their transaction were to be rolled back the local account would be rolled back as well.
We can trend the current weight of all representatives that are online and voting and make sure we have >50% of the vote weight accounted for before considering it settled.
 
 
Hey Colin, will you eventually have support for a Trezor or other hard wallet?
 
Yea we'll definitely work with companies like Trezor that are interested in being a hardware wallet for xrb. It's just a matter of making sure they support the signing algorithms and integrating with their API.
 
EDIT: I'm getting a lot of messages asking me how to buy XRB. I used this guide which was very helpful: https://www.reddit.com/RaiBlocks/comments/7i0co0/the_definitive_guide_to_buying_and_storing/
In short -- buy BTC on coinbase, open up an account on bitgrail, transfer that BTC from coinbase to bitgrail, then trade your BTC for XRB. It's a pain right now because it's such a new coin, but soon it will be listed on more exchanges, and hopefully on things like shapeshift/changelly. After that it will be much easier... but until then, the inconvenience is what we have to pay in order to get into XRB while its still early.
EDIT: BAD SCRIPT, BAD!
