}}
=Introduction=This section of the wiki aims to help document the development work done related to the Ravencoin networkand provide information for developers who want to build software and tools using Ravencoin.
Open weekly or fortnightly Every two weeks developer meetings take place on the Ravencoin Community discord server #development-meetings channel (https://discord.gg/jn6uhur). An archive of the dev chat meetings is available on IRC check Reddit (in the side panel) https://www.ravencointalkreddit.orgcom/r/postRavencoin/ravencoin-open-developer-meeting-9816968?pid=1305079154.
IRC: Several dev meeting summaries are available at https://webchatwww.freenoderavencoinplatform.netcom/?channels=ravencoin-dev
Archive of the conversation on the 10th Aug 2018 on Reddit httpsFor Ravencoin network details, see:* [http://www.redditravennodes.com/ Ravennodes.com] for node statistics.* [https://rvnstats.info/ Ravenstats.info] for mining difficulty, asset, hashrate, supply, block times, and more.* [https://rravencoin.network/Ravencoin.network] for transactions, addresses, pool stats, rich list, and more.* [https:/comments/96at36/irc_log_from_ravencoin_open_developer_meeting_augwww.ravencoinburn.org/Ravencoinburn.org] for a quick overview of burned Ravencoin.
Looks like future dev chats will be available on discord=Ravencoin platform development===Phase 1 - Ravencoin launch & mining algorithm - Jan 3rd, 2018==In addition to the [https://ravencoin.org/wp-content/uploads/2018/03/X16R-Whitepaper.pdf X16R algorithm], most of the core code changes are in [https://github.com/RavenProject/Ravencoin/blob/master/src/chainparams.cpp the chainparams] file.
The details are broken down on the wiki page: '''[[Chainparams]]'''. If you are looking to port existing Bitcoin applications to include Ravencoin - there are some useful parameters available from work done in the [https://github.com/brian112358/ledger-wallet-chrome/commit/303f5030059c805d808c83466275e078d06afbb5 Ledger integration code on GitHub]. Summarized on the wiki page: '''[[Ledger integration]]''' If you are looking for typical parameters needed for wallet integration - there is a summary on the '''[[Wallet integration]]''' page. It's worth mentioning, whilst we all try to keep these pages up to date, the RavenProject code on GitHub could change and these pages could become out of sync. Please validate on [https://github.com/RavenProject/Ravencoin https://github.com/RavenProject/Ravencoin]. =Core Code=Dark Gravity Wave - Aug 20th, 2018 == Ravencoin forked to include the Dark Gravity Wave difficulty adjustment to protect itself against hash rate attacks. The problem and solution to the problem was explained [https://medium.com/@tronblack/ravencoin-dark-gravity-wave-1da0a71657f7 here]. ==Phase 2&4 - Assets, Subassets & Unique assets - Nov 5th, 2018 ==Asset [https://medium.com/@tronblack/ravencoin-asset-faq-e0d04d460e9b FAQ] written by Tron on Medium ===Asset info for Main Net===Assets (cost 500 RVN):* Burn address: https://ravencoin.network/address/RXissueAssetXXXXXXXXXXXXXXXXXhhZGt* Token name - Must be unique* Number of tokens - From 1 to 21 billion* How divisible? - From not divisible to 8 decimal places (0.00000001)* Reissuable (yes/no)* Include meta-data (agreement, company, contact, etc) Subassets (cost 100 RVN):* Burn address: https://ravencoin.network/address/RXissueSubAssetXXXXXXXXXXXXXWcwhwL* Token name - Must be unique when combined with token* Number of tokens - From 1 to 21 billion* How divisible? - From not divisible to 8 decimal places (0.00000001)* Reissuable (yes/no) Unique Assets (cost 5 RVN) - create one-of-a-kind assets:* Burn address: https://ravencoin.network/address/RXissueUniqueAssetXXXXXXXXXXWEAe58* ART#VenusDeMilo* CAR#<VIN number>* COOLGAME#SwordOfThor Reissuing an Asset (cost 100 RVN):* Burn address: https://ravencoin.network/address/RXReissueAssetXXXXXXXXXXXXXXVEFAWu* Reissuing an asset lets you issue more, change decimal places, change ipfs hash, and/or change reissuability.
Currently organized into the phases ===Global burn address===If you want to get rid of [httpsfor example assets you do not want. You can send them to a global burn address://github.com/RavenProject/Ravencoin/tree/master/roadmap the roadmap] - this structure will probably change as the project matures.
==Phase 1==https://ravencoin.network/address/RXBurnXXXXXXXXXXXXXXXXXXXXXXWUo9FV
In addition to == New Mining Algorithm X16Rv2 - Oct 1st, 2019 ==[https://medium.com/@tronblack/ravencoin-asic-thoughts-e6c0079609e6 As it became evident that X16R ASICs were developed and mining Ravenvoin in July 2019], the X16R mining algorithm was adapted with a small modification to X16Rv2. This adaptation involved adding an extra hashing algorithmto three of the 16 existing ones, most of which greatly reduces the core code changes are in times an ASIC can be used (~3.5%). X16Rv2 was implemented using an [https://github.com/RavenProjectbitcoin/Ravencoinbips/blob/master/src/chainparamsbip-0099.cpp the chainparamsmediawiki#asic-reset-hardfork ASIC-reset-hardfork] file.
Development progress and code is available here: https://github.com/RavenCommunity ==Phase 3 - Dividends/Rewards - Feb 7th, 2020==Rewards, also sometimes called dividends, provides a way to send tokenized assets or RVN to token holders by percentage of tokens held. Dividend support can be done without modifying the protocol. Rewards do not require a consensus protocol change, and the rpc calls exist to be able do rewards already. These capabilities just make it native and easy-to-use from the client. ===Resources===* [https://github.com/RavenProject/Ravencoin/tree/master/roadmap/rewards The details are broken down Roadmap for Rewards is here on Github] ===Use examples===* Reward shareholders with profits (denominated in RVN)* Reward membership holders* Reward those that contributed the wiki page: most to a shared project and earned special tokens ==Phase 5 - Messaging, OIP, and Restricted Assets - Feb 7th, 2020==A message is "broadcast" if an owner token or channel token is sent in a transaction to the same address with the addition of an IPFS hash and an optional expiration date. The message isn't really broadcast in the sense of being transmitted to nodes, but rather each node will independently detect the special transaction type and display the message. Message display is subject to some heuristic anti-spam rules.  === IPFS Integration ===IPFS (Interplanetary File System) is used by Ravencoin for issuance meta-data, messaging, and transaction meta-data. Ravencoin must interact with IPFS in order to show messages because the message content is stored on IPFS. IPFS access should be on by default, but should be able to be turned off with a flag. A two phase approach will allow Ravencoin to use IPFS natively, but it will also use existing IPFS proxies. === OIP Integration ==='''[[Chainparams]](NEW)'''Open Index Protocol allows for richer meta data and will get support in Ravencoin in addition to IPFS. You can find more on what you can do with OIP [https://oip.wiki/Main_Page here]. You will have to choose between adding OIP or IPFS meta data. Fortunately, OIP metadata also allows for adding IPFS.
If you are looking to port existing Bitcoin applications === Restricted Assets ==='''(NEW)''' Restricted assets will be a new kind of assets that come with tags. The issuer can send tags to include Ravencoin - addresses that tell the entire chain that the asset can go there are some useful parameters available from work done in . The purpose of these restrictions is to limit the transferability of a token to known good actors, but without revealing the identity of the actors to anyone other than the [https://githuboriginal entity that verifies their identity.com/brian112358/ledger-wallet-chrome/commit/303f5030059c805d808c83466275e078d06afbb5 Ledger integration code on GitHub]Only when legally required to do so, would the verifier reveal the identity.
Summarised on It introduces 2 token types:* One starts with a $ and represents a completely new token type which is a Restricted Asset. Restricted Assets only move to Tagged addresses.* The other starts with a # and is a Tag. Tags tokens can only be transferred by the wiki page: '''[[Ledger integration]]'''issuer. Tag tokens can be sent or revoked only by the Tag issuer.
If you are looking Restricted assets offer a solution to SEC compliance for typical parameters needed security tokens: Ravencoin will allow for wallet integration appending externally- there validated trust from interested parties such as regulators, through intermediate Qualifiers such as KYC/AML provider consortia, down to individual addresses. Issuers of assets can leverage the tags to manage how their assets can move about the chain. In this way, affirmation of an address’ status (such as KYC/AML compliant, accredited investor, or current subscriber) is possible without exposing or replicating the addressee’s Personally Identifiable Information (PII), and where the burden of establishing and maintaining trust in these qualifying tags is a summary on borne primarily by the regulated entities and regulators that require such information in the '''[[Wallet integration]]''' pagefirst place.
It's worth mentioning, whilst we all try to keep these pages up to date, the ===Resources===* [https://medium.com/@tronblack/ravencoin-kaaawww-2f72077aece Messaging is decribed in the KAAAWWW! protocol]. * [https://github.com/RavenProject code on GitHub could change and these pages could become out of sync.

==Phase 2 - Assets =Use examples===* Send information about your token.* Send alerts relevant to your project.* Send information about a shareholder vote.* Use Raven messaging for other systems.
Asset testnet live== New Mining Algorithm KAWPOW (May 6th 2020) ==To battle ASICs in the long term, Ravencoin developers are developing a new hashing algorithm: KAWPOW, which is a variant of ProgPOW with parameters specifically for Ravencoin. Check The change will be implemented using an [[testnethttps://en.bitcoin.it/wiki/BIP_0099#ASIC-reset_hardfork ASIC reset hardfork ]] for .

Asset FAQ written An open source kawpowminer by Tron on Medium Ravencoin community devs is here: https://mediumgithub.com/@tronblackRavenCommunity/kawpowminer/ravencoin-asset-faq-e0d04d460e9breleases
==Phase 3==More info on mining here: https://medium.com/@jeroz9009/ravencoin-tutorial-kawpow-mining-748158f63e11
Rewards== BIP44 Seed Words in Raven Core Wallets (May 6th 2020) ==Ravencoin core is going to default to using BIP44 starting with version 4. The iOS and Android RVN Wallet is already BIP44, and Mango Farms web wallet is also BIP44.If you’ve already created a wallet before the version 4 release, then it will continue to use just the BIP32 HD derivation and should be backwards compatible with your existing wallet.dat file. If Ravencoin core does not find a wallet.dat, it will prompt you and give you 12-words to write down as your backup. You should still encrypt your wallet and never forget your password.
==Phase 4==See: https://blog.ravencoin.email/post/ravencoin-bip44
Unique assets==Phase 6 - Voting (Aim: Q4 2020 or later)==Ravencoin will support voting. Creating a vote will create vote tokens. These vote tokens are identical to normally issued tokens, except that they are created in exact qty and units as an already issued token. Vote tokens move just like regular tokens up until the block height when the vote expires. This allows vote token holders to send their vote to a delegate that might have better information about the topic and therefore cast a more informed vote. The feature will also allow voting by percentage of ownership. Second tier web voting can be built on top of this protocol.
==Phase 5=Resources===[https://github.com/RavenProject/Ravencoin/tree/master/roadmap/voting The Roadmap for Voting is here on Github]
Messaging===Example===Issue a special vote token to every holder of your token.* Send to <address X> to vote for X proposal* Send to <address Y> to vote for Y proposal
==Phase 67 - Compatible Mode (Kawwwmeleon)=='''04/01/2019 Dev Meeting update'''
VotingThe idea is to allow ravend to act as a daemon that looks like a single coin/token/asset. To realize this, the ravend daemon should be reconfigurable to listen to a transfer RPC call such as senttoaddress or sendfrom, but in this case it would be for a specific asset and not Ravencoin. This would allow easy asset integration into existing systems.
===Example===
The config for the asset FREE_HUGS might look like:
{"port":2222, "asset":"FREE_HUGS", "rpcuser":"hugger", "rpcpass":"gi3afja33"}
==Appendix==So, sendtoaddress on the new port (non-RVN port) would send FREE_HUGS.
From =Using the roadmap document Ravencoin platform===Dev Kit==The Ravencoin Dev Kit is available and maintained at https://github.com/RavenDevKit. The dev kit contains e.g., * A JavaScript Ravencoin library, * An Extensible full node,* A full stack for Ravencoin blockchain- based applications, * A Ravencoin blockchain explorer UI,* A Ravencoin blockchain API for web wallets,* Ravencoin Message Verification and Signing for Ravencore,* Interface to the bitcoin P2P network for Ravencore,* Tools for running a local Ravencore development node,* Website for https://ravencoin.com,* A client library to connect to Ravencoin RPC commands in JavaScript,* Debian packaging for working with assets:Ravencore, * A helper to add tasks to gulp,* x16r library for Ravencore,* Treat a collection of Buffers as a single contiguous partially mutable Buffer.
==Asset control=='' Current commands are as of v2.2.0. Be sure to check the QT wallet on github for up to date commands '' issue(to_address, asset_name, qty, to_address, change_address, units=1, reissuable=false, has_ipfs, ipfs_hash)
Issue an asset with unique name. Unit as 1 for whole units, or 0.00000001 for satoshi-like units. Qty should be whole number. Reissuable is true/false for whether additional units can be issued by the original issuer.
issueunique (root_name, asset_tags, ipfs_hash, to_address, change_address)
Creates a unique asset from a pool of assets with a specific name. Example: If the asset name is SOFTLICENSE, then this could make unique assets like SOFTLICENSE:38293 and SOFTLICENSE:48382 This would be called once per unique asset needed.
reissue (reissue asset_name, qty, to_address, change_address, reissuable, new_unit, new_ipfs )
Issue more of a specific asset. This is only allowed by the original issuer of the asset and if the reissuable flag was set to true at the time of original issuance.
transfer (asset_name, qty, to_address)
This sends assets from one asset holder to another.
listassets (assets, verbose, count, start)
This lists assets that have already been created.
listmyassets ( asset, verbose, count, start )
Lists your assets.
listassetbalancesbyaddress (address)
Lists asset balance by address.
listaddressesbyasset (asset_name)
Lists addresses by asset.
getassetdata (asset_name)
Lists asset data of an asset.
issuefrom(from_address, to_address, qty, units, units=1, reissuable=false)Detailed Asset Support == ===General===Issue an asset with unique name from a specific address -- allows control The Ravencoin network consists of which address/private_key is used to issue the asset. Unit as 1 for whole units, or 0.00000001 for satoshi-like units. Qty should be whole number. Reissuable is true/false for whether additional units can be issued by the original issuernodes communicating on port 8767.
The asset information is available by request on the network. Specify a list of asset names to request information about each asset. Requests for information on up to 512 assets can be made per request. Return messages will be sent separately. Asset not found information may be grouped together for optimization. Information about each asset is important for:* Asset creation because assets must be unique* Asset display because the asset information contains the number of decimal places to display.* Asset meta-data display - Requires the IPFS hash to show additional information about the asset.* Asset re-issue status to prevent reissuance attempts on a locked asset.* Asset qty issued to prevent reissuance attempts on a fully issued (21 billion) asset. There are three networks:<br /> Mainnet which uses a network identifier '''RAVN'''<br /> Testnet which uses a network identifier '''RVNT'''<br /> RegTest which uses a network identifier '''CROW'''<br /> issuemore An additional command has been added to the network for asset support. This can be used by SPV nodes to get information about assets without interacting with a centralized API or a Remote Procedure Call. ===Network call getassetdata(to_address)===The following is the specification for this new network call - available starting with network version 70018 Example 1: Request for asset name that doesn't exist Request -> getassetdata HEADER: 43524f5767657461737365746461746110000000571db430 DATA: 010e4241445f41535345545f4e414d45 Data Breakdown: 01 - Varint size of the vector 0e - Size of element = e.g. 14 Bytes 4241445f41535345545f4e414d45 - Name of asset = e.g. "BAD_ASSET_NAME" -------------------------------------------------------------------- Response -> asstnotfound HEADER: 43524f57617373746e6f74666f756e6410000000571db430 DATA: 010e4241445f41535345545f4e414d45 Data Breakdown: 01 - Varint size of the vector Oe - Size of element = e.g. 14 Bytes 4241445f41535345545f4e414d45 - Name of asset = e.g. "BAD_ASSET_NAME" Example 2: Request for asset name that does exist, asset_name, qty)and an asset that doesn't exist Request -> getassetdata HEADER: 43524f576765746173736574646174611d0000004a54c291 DATA: 020c41535345545f4a4552454d590e4241445f41535345545f4e414d45 Data Breakdown: 02 - Varint size of the vector 0c - Size of element = e.g. 12 Bytes 41535345545f4a4552454d59 - Name of asset = e.g. "ASSET_JEREMY" 0e - Size of element = e.g. 14 Bytes 4241445f41535345545f4e414d45 - Name of asset = e.g. "BAD_ASSET_NAME" -------------------------------------------------------------------- First Response -> assetdata HEADER: 43524f576173736574646174610000001d000000200a58aa DATA: 0c41535345545f4a4552454d5900e1f50500000000 00010000f5010000 Data Breakdown: 0c - Size of name = e.g. 12 Bytes 41535345545f4a4552454d59 - Name of asset = e.g. "ASSET_JEREMY" 00e1f50500000000 - Amount = e.g. 100000000 00 - Units = e.g. 0 01 - Reissuable = e.g. 1 00 - hasIPFS = e.g. 0 00 - Size of IPFS hash f5010000 - Block height Second Response -> asstnotfound HEADER: 43524f57617373746e6f74666f756e6410000000571db430 DATA: 010e4241445f41535345545f4e414d45 Data Breakdown: 01 - Varint size of the vector Oe - Size of element = e.g. 14 Bytes 4241445f41535345545f4e414d45 - Name of asset = e.g. "BAD_ASSET_NAME" Examples 3: Request for asset name that contains an IPFS HASH Request -> getassetdata HEADER: 43524f5767657461737365746461746118000000e6218523 DATA: 011641535345545f4a4552454d595f574954485f49504653 Data Breakdown: 01 - Varint size of the vector 16 - Size of element = e.g. 22 Bytes 41535345545f4a4552454d595f574954485f49504653 - Name of asset = e.g. "ASSET_JEREMY_WITH_IPFS" -------------------------------------------------------------------- Response -> assetdata HEADER: 43524f5761737365746461746100000049000000cb345766 DATA: 1641535345545f4a4552454d595f574954485f4950465300e1f50500000000000101221220da203afd5eda1f45deeafb70ae9d5c15907cd32ec2cd747c641fc1e9ab55b8e8f6010000 Data Breakdown: 16 - Size of name = e.g. 22 Bytes 41535345545f4a4552454d595f574954485f49504653 - Name of asset = e.g. "ASSET_JEREMY_WITH_IPFS" 00e1f50500000000 - Amount = e.g. 100000000 00 - Units = e.g. 0 01 - Reissuable = e.g. 1 01 - hasIPFS = e.g. 0Issue more 22 - Size of IPFS hash - 34 Bytes 1220da203afd5eda1f45deeafb70ae9d5c15907cd32ec2cd747c641fc1e9ab55b8e8 - IPFS hash data f6010000 - Block height ==IPFS - InterPlanetary File System==You can add a specific document to an assetas metadata for any purpose, such as instructions, a low-res image of a piece of art that is represented by the token, your website, etc. This Messaging will also support IPFS. Currently, there is only allowed by not (yet) IPFS support directly in the Raven wallet.
