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!

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!

Transcript from Ravencoin Open Developer Meeting - Nov. 16, 2018

Tron at 2:03 PM

Topics: Messaging (next phase) UI 2.2 - Build from develop - still working out a few kinks Mobile - Send/Rcv/View Assets - In progress Raven Dev Kit -Status

RavencoinDev at 2:04 PM

Hey Everybody! Let's get started!Thanks Tron for posting the topics.Tron is going talk about Messaging Plans.Let's start there.

Chatturga at 2:06 PM

It looks like this channel is not connected to the IRC. One moment

RavencoinDev at 2:07 PM

Well, we going to move forward as the tech guys fix the IRC connections.

Tron at 2:07 PM

I wanted to have a doc describing the messaging, but it isn't quite ready.I understand this isn't going to IRC yet, but I'm starting anyway.

RavencoinDev at 2:08 PM

Look for it soon on a Medium near you.

Tron at 2:08 PM

Summary version: Every transaction can have an IPFS hash attached.

Vincent at 2:09 PM

any plans for a 'create IPFS' button?

RavencoinDev at 2:09 PM

Yes

Vincent at 2:09 PM

on asset creatin window also?

RavencoinDev at 2:09 PM

Yes

Vincent at 2:09 PM

sweet

Tron at 2:09 PM

IPFS attachments for transactions that send ownership token or channel token back to the same address will be considered broadcast messages for that token.The client will show the message.Some anti-spam measures will be introduced.If a token is in a new address, then messages will be on by default.The second token in an address, the channel will be available, but muted by default.

RavencoinDev at 2:11 PM

That way I can't spam out 21b tokens and then start sending messages to everybody.

Tron at 2:11 PM

We'd like to have messaging in a reference client on all six platforms.

corby at 2:11 PM

Hi!

Tron at 2:11 PM

Photos will not be shown. Messages will be "linkified"

RavencoinDev at 2:12 PM

and plain text.We'll start with the QT wallet support

Tron at 2:12 PM

Any other client is free to show any IPFS message they choose.The messaging is fully transparent.

Rikki RATTOE at 2:13 PM

ok, so messaging isn't private

Tron at 2:13 PM

Anyone could read the chain and see the messages.

RavencoinDev at 2:13 PM

No, never was planned to be private

MSFTserver-mine more @ MinerMore at 2:13 PM

irc link should be fixed

Tron at 2:13 PM

It is possible to put encrypted content in the IPFS, but then you'd have to distribute the key somehow.

RavencoinDev at 2:13 PM

Thanks MSFT!

Chatturga at 2:13 PM

Negative

Tron at 2:14 PM

Core protocol changes Extend the OP_RVN_ASSET to include for any transfer: RVNT <0xHH><0x12><0x20><32 bytes encoding 256 bit IPFS hash> 0xHH - File type 0x00 - NO data, 0x01 - IPFS hash, 0x02 through 0xFF RESERVED 0x12 - IPFS Spec - Using SHA256 hash 0x20 - IPFS Spec - 0x20 in hex specifying a 32 byte hash. …. (32 byte hash in binary)

corby at 2:14 PM

By it's nature nothing on chain is private per se. Just like with wallets you'd need to use crypto to secure messaging between parties.

Tron at 2:14 PM

Advantages: This messaging protocol has the advantage of not filling up the blockchain. The message information is public so IPFS works as a great distributed store. If the messages are important enough, then the message sender can run nodes that "PIN" the message to keep a more durable version. The message system cannot be spoofed because any change in the message will result in a different hash, and therefore the message location will be different. Only the unique token holder can sign the transaction that adds the message. This prevents spam. Message clients (wallets), can opt-in or opt-out of messages by channel. Meta-message websites can allow viewing of all messages, or all messages for a token. A simple single channel system is supported by the protocol, but a channel could be sub-divided by a client to have as many sub-channels as desired. There are no limits on the number of channels per token, but each channel requires the 5 RVN fee to create the channel.

RavencoinDev at 2:14 PM

So, somebody could create their own client and encrypt the data on the blockchain if they wished.

corby at 2:15 PM

Wow Tron types fast

Rikki RATTOE at 2:15 PM

yeah there was some confusion in the community whether messaging would be private and off chain

Tron at 2:15 PM

Anti-Spam Strategy One difficulty we have is that tokens can be sent to any Ravencoin asset holder unsolicited. This happens on other asset platforms like Counterparty. In many cases, this is good, and is a way for asset issuers to get their token known. It is essentially an airdrop. However, combined with the messaging capabilities of Ravencoin, this can, and likely will become a spam strategy. Someone who wants to send messages (probably scams) to Ravencoin asset holders, which they know are crypto-savvy people, will create a token with billions of units, send it to every address, and then message with the talking stick for that token. Unless we preemptively address this problem, Ravencoin messaging will become a useless spam channel. Anyone can stop the messages for an asset by burning the asset, or by turning off the channel. A simple solution is to automatically mute the channel (by default) for the 2nd asset sent to an address. The reason this works is because the assets that you acquire through your actions will be to a newly generated address. The normal workflow would be to purchase an asset on an exchange, or through a ICO/STO sale. For an exchange, you'll provide a withdrawal address, and best practice says you request a new address from the client with File->'Receiving addresses…'->New. To provide an address to the ICO/STO issuer, you would do the same. It is only the case where someone is sending assets unsolicited to you where an address would be re-used for asset tokens. This is not 100% the case, and there may be rare edge-cases, but would allow us to set the channels to listen or silent by default. Assets sent to addresses that were already 'on-chain' can be quarantined. The user can burn them or take them out of quarantine.

RavencoinDev at 2:18 PM

Okay, let me know when/if you guys read through all that. 📷📷2

corby at 2:18 PM

To be clear this is a client-side issue -- anyone will be able to send anything (including messages) to any address on chain..

RavencoinDev at 2:18 PM

It'll be in the Medium post later.

Tron at 2:19 PM

@corby The reference client will only show messages signed by the issuer or designated channels.Who is ready for another wall of text? 📷

corby at 2:19 PM

I hear that's the plan 📷 just pointing out that it is on the client in these cases..

Tron at 2:20 PM

Yes, any client can show anything gleaned from the chain.Goal: A simple message format without photos. URL links are allowed and most clients will automatically "linkify" the message for valid URLs. For display, message file must be a valid json file. { "subject":"This is the optional subject", "message": "This is required.", "expires": 1578034800 } Only "message" is required {"message":"Hello world"}

bhorn at 2:21 PM

expires?

Vincent at 2:21 PM

discount coupon?

Tron at 2:21 PM

If you have a message that worthless (say after a vote), just don't show the message.

bhorn at 2:21 PM

i see - more client side operation

corby at 2:21 PM

/expires

Tron at 2:22 PM

Yep. And the expiration could be used by IPFS pinners to stop worrying about the message. Optional

RavencoinDev at 2:22 PM

If the client sees a message that is expired it just won't display it.

Vincent at 2:23 PM

will that me messaged otherwise may cause confusion?"expired'

RavencoinDev at 2:23 PM

YesWe'll do our best to make it intuitive.

Tron at 2:24 PM

Client handling of messages Pop-up messages or notifications when running live. Show messages for any assets sent to a new address - by default Mute messages for assets sent to an address that was already on-network. Have a setting to not show messages older than X IPFSHash (or 8 bytes of it) =

Rikki RATTOE at 2:25 PM

will there be a file size limit for IPFS creation in the wallet?

RavencoinDev at 2:25 PM

We'll also provide updated documentation.

Tron at 2:26 PM

Excellent question Rikki. Here are some guidelinesGuidelines: Clients are free to show or not show poorly formed messages. Reference clients will limit message display to properly formed messages. If subject is missing, the first line of the message will be used (up to 80 chars). Standard JSON encoding for newlines, tabs, etc. https://www.freeformatter.com/json-escape.html Expiration is optional, but desired. Will stop showing the message after X date, where X is specified as Unix Epoch. Good for invites, voting requests, and other time sensitive messages that have no value after a specific date. By default clients will not show a message after X blocks (default 1 year) Amount of subject shown will be client dependent - Reference client may cut off at 80 chars. Messages longer than 15,000 (about 8 pages) will not be pinned to IPFS by some scanners. Messages longer than 15,000 characters may be rejected altogether by the client. Images will not be shown in reference clients. Other clients may show any IPFS content at their discretion. IPFSHash is only a "published" message if the Admin/Owner or Channel token is sent from/to the same address. This allows for standard transfers with metadata that don't "publish".Free Online JSON Escape / Unescape Tool - FreeFormatter.comA free online tool to escape or unescape JSON strings

RavencoinDev at 2:26 PM

We're hoping to add preferences that will allow the user to customize their messaging experience.

Tron at 2:27 PM

Also, happy to receive feedback from everyone.

corby at 2:27 PM

In theory though if you maintain your own IPFS nodes you should be able to reference files of whatever size right?

Steelers at 2:27 PM

How about a simple Stop light approach - Green (ball) New Message, Yellow (Ball) Expiring Messages, Red (Ball) Expired Messages

RavencoinDev at 2:27 PM

Yes please! That's the point of sharing it here

Chatturga at 2:27 PM

Fixt

push | ravenland.org at 2:28 PM

Thanks @Tron can you provide any details of the coming 'tooling' at the end of november, and what that might enable (apologies as I am a bit late to meeting if this has been asked already)

VeronicaBOT at 2:28 PM

sup guys

Tron at 2:28 PM

Sure, that's coming.

RavencoinDev at 2:28 PM

That's the Raven WebDev Kit topic coming up in a few mins.

push | ravenland.org at 2:29 PM

oki 📷 cheers

RavencoinDev at 2:29 PM

Questions on messaging?

Jeroz at 2:30 PM

Not sure if I missed it, but how fast could you send multiple messages in succession?

BruceFenton at 2:30 PM

Some kind of sweep feature or block feature for both tokens and messages could be useful Certain messages will be illegal to possess in certain jurisdictions If someone sends a picture of Tiennneman tank man in China or a message calling for the overthrow of a ruler it could be illegal for someone to have There’s no way for that jurisdiction to censor the chain So some users might want the option to purge messages or not receive them client side / on the wallet

Tron at 2:30 PM

Messages are a transaction.

RavencoinDev at 2:30 PM

So it'll cost you to spam messages.They can only send a hash to that picture and the client won't display anything not JSON

corby at 2:31 PM

purge/block is the age old email spam

Tron at 2:31 PM

The Reference client - other clients / web sites, etc can show anything they wish.

RavencoinDev at 2:31 PM

You can also burn a token if you never want to receive messages from that token owner.

UserJonPizza|MinePool.com|Mom at 2:32 PM

Can't they just resend the token?

Tron at 2:33 PM

Yes, but it would default to mute.📷2

RavencoinDev at 2:33 PM

meaning it would show up in a spam foldetab

bhorn at 2:33 PM

is muting available for the initial asset as well?

RavencoinDev at 2:33 PM

Something easy to ignore if muted.

Tron at 2:33 PM

@bhorn Yes

BruceFenton at 2:33 PM

Can users nite some assets and not others?

Tron at 2:33 PM

@bhorn It just isn't the default.

BruceFenton at 2:33 PM

Mute

RavencoinDev at 2:33 PM

YesYou can mute per token.

BruceFenton at 2:34 PM

Great

Tron at 2:34 PM

And per token per channel.

Jeroz at 2:34 PM

channels are the subtokens?

BruceFenton at 2:34 PM

What’s per token per channel mean ?

Tron at 2:34 PM

The issuer sends to the "Primary" channel.Token owner can create channels like "Alert", "Emergency", etc.These "talking sticks" are similar to unique assets.📷1ASSET~Channel

RavencoinDev at 2:37 PM

Okay, we have a few more topics to cover today.Tron will post more details on Medium and we can continue discussions there.

Jeroz at 2:38 PM

Ah, I missed channel creation bit for each token with the 5 RVN / channel cost. It makes more sense to me now.

RavencoinDev at 2:38 PM

The developers are working towards posting a new version 2.2 that has the updated UI shown on twitter.

Vincent at 2:39 PM

twit link?

RavencoinDev at 2:39 PM

The consuming of large birds (not ravens) might slow the release a bit.So likely the week after Thanksgiving.

[Dev] Blondfrogs at 2:39 PM

The new UI will contain: - New menu layout - New icons - Dark mode - Added RVN colors

Dan1666 at 2:39 PM

+1 Dark mode

RavencoinDev at 2:39 PM

DARK MODE!

Dan1666 at 2:40 PM

so pleased about that

RavencoinDev at 2:40 PM

I can honestly say it'll be the nicest crypto wallet out there.

[Dev] Blondfrogs at 2:40 PM

A little sneak peak, but this is not the final project📷📷6📷3

!S1LVA | MINEPOOL at 2:40 PM

Outstanding

Dan1666 at 2:41 PM

reminds me of Sub7 ui for those that might remember

UserJonPizza|MinePool.com|Mom at 2:41 PM

Can we have an asset count at the top?

[Dev] Blondfrogs at 2:41 PM

Icons will be changing

Vincent at 2:41 PM

does the 'transfer assets' have a this for that component?

Tron at 2:41 PM

Build from develop to see the sneak preview in action.There may be small glitches depending on OS. These are being worked on.

Rikki RATTOE at 2:41 PM

No plans for the mobile wallet to show an IPFS image I'm assuming? Would be a nice feature if say a retail store could send a QR coupon code to their token holders and they could scan the coupon using their wallet in store

[Dev] Blondfrogs at 2:42 PM

@Vincent That will probably be a different section added later📷1

RavencoinDev at 2:42 PM

Yes, Rikki we do want to support messaging.Looking into how that would work with Apple and Google push.

push | ravenland.org at 2:42 PM

sub7📷1hahaoldschoolit so is similar aswell

[Master] Roshii at 2:43 PM

Messages are transactions no need for any push

Tron at 2:43 PM

@Rikki RATTOE There's a danger in showing graphics where anyone can post anything without accountability for their actions. A client that only shows tokens for a specific asset could do this📷1

RavencoinDev at 2:43 PM

True, unless you want to see the messages even if you haven't opened your wallet in a week.

Rikki RATTOE at 2:44 PM

the only thing I was thinking was if you simply linked the image, somebody could just copy the link and text it off to everyone and the coupon isn't all that exclusive

UserJonPizza|MinePool.com|Mom at 2:44 PM

Maybe a mobile link-up for a easy way to see messages by just importing pubkey(edited)

RavencoinDev at 2:45 PM

Speaking of mobileWe are also getting close to a release of mobile that includes the ability to show assets held, and transfer them.Roshii has been hard at work.📷6📷1

Vincent at 2:46 PM

can be hidden also?

RavencoinDev at 2:47 PM

We're still finalizing the UI design but that is on the list of todos📷1

Under at 2:47 PM

Could we do zerofee mempool messaging that basically gets destroyed after it expires out of the mempool for real-time stealth mode messaging

corby at 2:48 PM

That's interesting!

RavencoinDev at 2:49 PM

There are other solutions available for stealth messaging, that's not what the devs had intended to build. It does sound cool though @Under

Under at 2:50 PM

📷 we’ll keep up the good work. Looking forward to the db upgrades. Will test this weekend

RavencoinDev at 2:50 PM

Thanks!That leaves us with 10 minutes for the Dev Kit!Corby has been working on expanding some of the awesome work that @Under has been doing.

corby at 2:52 PM

Yes -- all of the -addressindex rpc calls are being updated to work with assets

RavencoinDev at 2:52 PM

Hopefully we'll be able to post the source soon once the initial use cases are all working.

corby at 2:52 PM

so assets are being tied into transaction history, utxos, etc

RavencoinDev at 2:52 PM

The devs want to provide a set of API's that make it easy for web developers to build solutions on top of Ravencoin.VinX is investigating the possibility of using Ravencoin to power their solution.

corby at 2:53 PM

will be exposed via insight-api which we've forked from @Under

[Master] Roshii at 2:53 PM

Something worth bringing up is that you will be able to get specific asset daba from full nodes with specific message protocols.

corby at 2:54 PM

also working on js lib for client side construction of asset transactions

Tron at 2:55 PM

Dev Kit will be an ongoing project so others can contribute and extend the APIs and capabilities of the 2nd layer.📷3📷3

RavencoinDev at 2:55 PM

Will be posted soon to the RavenProject GitHub.

corby at 2:55 PM

separate thing but yes Roshii that is worth mentioning -- network layer for getting asset data

RavencoinDev at 2:55 PM

Again want to give thanks to @Under for getting a great start on the project

push | ravenland.org at 2:56 PM

Yes looking forward to seeing more on the extensive api and capabilities, is there a wiki on this anywhere tron?(as to prevent other people replicating eachothers work?)

RavencoinDev at 2:56 PM

The wiki will be in the project on GitHub

push | ravenland.org at 2:56 PM

im guessing when the kit is released, something will appear, okok cool

RavencoinDevat 2:57 PM

Any questions about the Web DevKit?

well, what kind of support will it give us, that would be nice, is this written anywhereI'm still relatively new to blockchain<2 yearsso need some hand holding i suppose 📷

bhorn at 2:58 PM

right, what are initial use cases of the devkit?

push | ravenland.org at 2:58 PM

i mean im guessing metamask like capabilitysome kind of smart contract, some automation capabilitiesrpc scriptsstuff like thiseven if proof of concept or examplei guess im wondering if my hopes are realistic 📷

RavencoinDev at 2:59 PM

You can see the awesome work that @Under has already don that we are building on top of.

push | ravenland.org at 2:59 PM

ok, sweet, that is very encouragingthanks @Under for making that code public

corby at 3:00 PM

It will hopefully allow you to write all sorts of clients -- depending on complexity of use case you might just have js lib (wallet functions, ability to post txs to gateway) or a server side project (asset explorer or exchange)..(edited)

Tron at 3:00 PM

Yeah, thanks @Under .

Secure paper wallet tutorial

This is my handout for paranoid people who want a way to store bitcoin safely. It requires a little work, but this is the method I use because it should be resistant to risks associated with:
  1. Bad random number generators
  2. Malicious or flawed software
  3. Hacked computers
If you want a method that is less secure but easier, skip to the bottom of this post.
The Secure Method
  1. Download bitaddress.org. (Try going to the website and pressing "ctrl+s")
  2. Put the bitaddress.org file on a computer with an operating system that has not interacted with the internet much or at all. The computer should not be hooked up to the internet when you do this. You could put the bitaddress file on a USB stick, and then turn off your computer, unplug the internet, and boot it up using a boot-from-CD copy of linux (Ubuntu or Mint for example). This prevents any mal-ware you may have accumulated from running and capturing your keystrokes. I use an old android smart phone that I have done a factory reset on. It has no sim-card and does not have the password to my home wifi. Also the phone wifi is turned off. If you are using a fresh operating system, and do not have a connection to the internet, then your private key will probably not escape the computer.
  3. Roll a die 62 times and write down the sequence of numbers. This gives you 2160 possible outcomes, which is the maximum that Bitcoin supports.
  4. Run bitaddress.org from your offline computer. Input the sequence of numbers from the die rolls into the "Brain Wallet" tab. By providing your own source of randomness, you do not have to worry that the random number generator used by your computer is too weak. I'm looking at you, NSA ಠ_ಠ
  5. Brain Wallet tab creates a private key and address.
  6. Write down the address and private key by hand or print them on a dumb printer. (Dumb printer means not the one at your office with the hard drive. Maybe not the 4 in 1 printer that scans and faxes and makes waffles.) If you hand copy them you may want to hand copy more than one format. (WIF and HEX). If you are crazy and are storing your life savings in Bitcoin, and you hand copy the private key, do a double-check by typing the private key back into the tool on the "Wallet Details" tab and confirm that it recreates the same public address.
  7. Load your paper wallet by sending your bitcoin to the public address. You can do this as many times as you like.
  8. You can view the current balance of your paper wallet by typing the public address into the search box at blockchain.info
  9. If you are using an old cell phone or tablet do a factory reset when you are finished so that the memory of the private keys is destroyed. If you are using a computer with a boot-from-CD copy of linux, I think you can just power down the computer and the private keys will be gone. (Maybe someone can confirm for me that the private keys would not be able to be cached by bitaddress?)
  10. To spend your paper wallet, you will need to either create an offline transaction, or import the private key into a hot wallet. Creating an offline transaction is dangerous if you don't know what you are doing. Importing to a client side wallet like Bitcoin-Qt, Electrum, MultiBit or Armory is a good idea. You can also import to an online wallet such as Blockchain.info or Coinbase.
Trusting bitaddress.org
The only thing you need bitaddress.org to do is to honestly convert the brainwallet passphrase into the corresponding private key and address. You can verify that it is doing this honestly by running several test passphrases through the copy of bitaddress that you plan on using, and several other brainwallet generators. For example, you could use the online version of bitaddress, and brainwallet and safepaperwallet and bitcoinpaperwallet. If you are fancy with the linux command line, you can also try "echo -n my_die_rolls | sha256sum". The linux operating system should reply with the same private key that bitaddress makes. This protects you from a malicious paper wallet generator.
Trusting your copy of bitaddress.org
Bitaddress publishes the sha1 hash of the bitaddress.org website at this location:
https://www.bitaddress.org/pgpsignedmsg.txt
The message is signed by the creator, pointbiz. I found his PGP fingerprint here:
https://github.com/pointbiz/bitaddress.org/issues/18
"527B 5C82 B1F6 B2DB 72A0 ECBF 8749 7B91 6397 4F5A"
With this fingerprint, you can authenticate the signed message, which gives you the hash of the current bitaddress.org file. Then you can hash your copy of the file and authenticate the file.
I do not have a way to authenticate the fingerprint itself, sorry. According to the website I linked to, git has cryptographic traceability that would enable a person to do some research and authenticate the fingerprint. If you want to go that far, knock yourself out. I think that the techniques described in this document do not really rely on bitaddress being un-corrupt. Anyway, how do we know pointbiz is a good guy? ;-)
There are a lot of skilled eyes watching bitaddress.org and the signed sha1 hash. To gain the most benefit from all of those eyes, it's probably worthwhile to check your copy by hashing it and comparing to the published hash.
"But we aren't supposed to use brainwallets"
You are not supposed to use brainwallets that have predictable passphrases. People think they are pretty clever about how they pick their passphrases, but a lot of bitcoins have been stolen because people tend to come up with similar ideas. If you let dice generate the passphrase, then it is totally random, and you just need to make sure to roll enough times.
How to avoid spending your life rolling dice
When I first started doing this, I rolled a die 62 times for each private key. This is not necessary. You can simply roll the die 62 times and keep the sequence of 62 numbers as a "seed". The first paper address you create would use "my die rolls-1" as the passphrase, the second would be "my die rolls-2" and so on. This is safe because SHA256 prevents any computable relationship between the resulting private key family.
Of course this has a certain bad security scenario -- if anyone obtains the seed they can reconstruct all of your paper wallets. So this is not for everyone! On the other hand, it also means that if you happen to lose one of your paper wallets, you could reconstruct it so long as you still had the seed.
One way to reduce this risk is to add an easy to remember password like this: "my die rolls-password-1".
If you prefer, you can use a technique called diceware to convert your die rolls to words that still contain the same quantity of entropy, but which could be easier to work with. I don't use diceware because it's another piece of software that I have to trust, and I'm just copy/pasting my high entropy seed, so I don't care about how ugly it is.
Why not input the dice as a Base 6 private key on the Wallet Details tab?
Two reasons. First of all, this option requires that you roll the die 99 times, but you do not get meaningful additional protection by rolling more than 62 times. Why roll more times if you don't have to? Second, I use the "high entropy seed" method to generate multiple private keys from the same die rolls. Using the Base 6 option would require rolling 99 times for every private key.
I'm a big nerd with exotic dice. How many times to roll?
Put this formula in Excel to get the number of times to roll: "=160*LOG(2,f)" where f = number of faces on the die. For example, you would roll a d16 40 times. By the way, somewhat unbelievably casino dice are more fair than ordinary dice
The "Change address" problem:
You should understand change addresses because some people have accidentally lost money by not understanding it.
Imagine your paper wallet is a 10 dollar bill. You use it to buy a candy bar. To do this you give the cashier the entire 10 dollar bill. They keep 1 dollar and give you 9 dollars back as change.
With Bitcoin, you have to explicitly say that you want 9 dollars back, and you have to provide an address where it should go to. If you just hand over the 10 dollar bill, and don't say you want 9 dollars back, then the miner who processes the transaction gives 1 dollar to the store and keeps the remainder themselves.
Wallet software like Bitcoin-Qt handles this automatically for you. They automatically make "change addresses" and they automatically construct transactions that make the change go to the change address.
There are three ways I know of that the change problem can bite you:
  1. You generate a raw transaction by hand, and screw up. If you are generating a transaction "by hand" with a raw transaction editor, you need to be extra careful that your outputs add up to the same number as your inputs. Otherwise, the very lucky miner who puts your transaction in a block will keep the difference.
  2. You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the paper wallet. The change is not in the paper wallet. It is in a change address that the wallet software generated. That means that if you lose your wallet.dat file you will lose all the change. The paper wallet is empty.
  3. You import a paper wallet into a wallet software and spend part of it, and then think that the change is in the change address that the wallet software generated. If the transaction did not need to consume all of the "outputs" used to fund the paper wallet, then there could be some unspent outputs still located at the address of the paper wallet. If you destroyed the paper wallet, and destroyed the copy of the private key imported to the wallet software, then you could not access this money. (E.g. if you restored the software wallet from its seed, thinking all of the money was moved to the wallet-generated change addresses.)

The hot paper wallet problem
Your bitcoin in your paper wallet are secure, so long as the piece of paper is secure, until you go to spend it. When you spend it, you put the private key onto a computer that is connected to the internet. At this point you must regard your paper wallet address as hot because the computer you used may have been compromised. It now provides much less protection against theft of your coins. If you need the level of protection that a cold paper wallet provides, you need to create a new one and send your coins to it.
Destroying your paper wallet address
Do not destroy the only copy of a private key without verifying that there is no money at that address. Your client may have sent change to your paper wallet address without you realizing it. Your client may have not consumed all of the unspent outputs available at the paper wallet address. You can go to blockchain.info and type the public address into the search window to see the current balance. I don't bother destroying my used/empty paper wallet addresses. I just file them away.
Encrypting your private key
BIP 0038 describes a standardized way to encrypt your paper wallet private key. A normal paper wallet is vulnerable because if anyone sees the private key they can take the coins. The BIP38 protocol is even resistant to brute force attacks because it uses a memory intensive encryption algorithm called scrypt. If you want to encrypt your wallets using BIP38, I recommend that you use bitcoinpaperwallet because they will let you type in your own private key and will encrypt it for you. As with bitaddress, for high security you should only use a local copy of this website on a computer that will never get connected to the internet.
Splitting your private key
Another option for protecting the private key is to convert it into multiple fragments that must be brought together. This method allows you to store pieces of your key with separate people in separate locations. It can be set up so that you can reconstitute the private key when you have any 2 out of the 3 fragments. This technique is called Shamir's Secret Sharing. I have not tried this technique, but you may find it valuable. You could try using
