=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.
=Ravencoin platform development=
The details are broken down on the wiki page: '''[[Chainparams]]'''.
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].
==Phase 2&4 Dark Gravity Wave - AssetsAug 20th, Subassets & Unique assets 2018 == Asset testnet live. Check [[testnet]] for more details, and [[Testnet-technical]] for details about the anatomy of a Ravencoin asset transaction script.

== 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 algorithm to three of the 16 existing ones, which greatly reduces the times an ASIC can be used (~3.5%). X16Rv2 was implemented using an [https://github.com/bitcoin/bips/blob/master/bip-0099.mediawiki#asic-reset-hardfork ASIC-reset-hardfork]. 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 Roadmap for Rewards is here on Github] ===Use examples===* Reward shareholders with profits (denominated in RVN)* Reward membership holders* Reward those that contributed the 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.
* Send information about your token.
* Send alerts relevant to your project.
* Use Raven messaging for other systems.
==Phase 6 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. The change will be implemented using an [https://en.bitcoin.it/wiki/BIP_0099#ASIC-reset_hardfork ASIC reset hardfork ]. For more info on how to mine, see https://minermore.com/docs/help/ravencoin_fork/ An open source kawpowminer by Ravencoin community devs is here: https://github.com/RavenCommunity/kawpowminer/releases More info on mining here: https://medium.com/@jeroz9009/ravencoin-tutorial-kawpow-mining- Voting748158f63e11 ==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. See: https://blog.ravencoin.email/post/ravencoin-bip44
==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.
===Resources===
[https://github.com/RavenProject/Ravencoin/tree/master/roadmap/voting The Roadmap for Voting is here on Github]
===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 7 - Compatible Mode(Kawwwmeleon)==Allows newly created assets '''04/01/2019 Dev Meeting update''' The idea is to allow ravend to appear exactly act as a daemon that looks like RVNa single coin/token/asset. To realize this, LTCthe ravend daemon should be reconfigurable to listen to a transfer RPC call such as senttoaddress or sendfrom, or Bitcoin but in this case it would be for a specific asset and not Ravencoin. This would allow easy asset integration into exchangesexisting systems. ===Example===The config for the asset FREE_HUGS might look like: {"port":2222, wallets"asset":"FREE_HUGS", explorers"rpcuser":"hugger", etc."rpcpass":"gi3afja33"} This speeds adoption into So, sendtoaddress on the larger crypto ecosystemnew port (non-RVN port) would send FREE_HUGS.
=Using the Ravencoin platform=
==Dev Kit=='' Current commands are as of Oct 13thThe 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, 2018* Website for https://ravencoin. Be sure com,* A client library to connect to check the QT wallet on github Ravencoin RPC in JavaScript,* Debian packaging for up Ravencore, * A helper to add tasks to date commands ''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 (asset_name, qty, to_address, change_address, units, reissuable, 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.
getassetdata (asset_name)
Lists asset data of an asset.
== Detailed Asset Support ==
===General===
The Ravencoin network consists of nodes 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 />
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.

==IPFS - InterPlanetary File System==
You can add a document to an asset as metadata for any purpose. Such , such as instructions, a low-res image of a piece of art that is represented by the token, your website, etc. Messaging will also support IPFS.
Currently, there is not (yet) IPFS support directly in the Raven wallet. However, you can upload content to e.g., https://globalupload.io/ and add the hash of the content to the asset that you are creating.

= Testnet =
This testnet network will be a completely independent secondary blockchain for testing purposes only, in which all tokens will have no intrinsic value and will not be traded on exchanges. The purpose of a testnet is to test features and functionality before introducing those features and functionality to the main blockchain. It is a playground to experiment and test different features with almost no cost to transact or mine blocks. During this testing phase, the Ravencoin blockchain itself will continue to maintain the same operation and functionality it has today.
To run your current wallet in testnet mode(Windows):
# First shutdown your current full client wallet.
# Create a shortcut to your raven-qt.exe with this in # Right click the shortcut, choose details and add '-testnet' to the target field. Example: <br /> <pre>"C:\Users\<username>\Path\to\executable\raven-qt.exe" –testnet</pre>
# Open the wallet by clicking on the shortcut you just made, and let the blockchain sync fully
