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 [[Wallet integration]https://github.com/bitcoin/bips/blob/master/bip-0099.mediawiki#asic-reset-hardfork ASIC-reset-hardfork]''' page.

(20 Aug 2018) In addition to asset functionality being on available to test on testnet ==Phase 5 - Messaging, OIP, and Restricted Assets - Ravencoin Feb 7th, 2020==A message is "broadcast" if an owner token or channel token is forking sent in a transaction to include Dark Gravity Wave to protect itself against the same address with the addition of an IPFS hash rate attacks - exchanges and mining pools need to upgrade as soon as possible 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 latest wallet release, users as soon as they want message. Message display is subject to use their coinssome heuristic anti-spam rules. [[Forks_and_updates]]
Asset costs:=== IPFS Integration ===* Asset IPFS (Interplanetary File System) is used by Ravencoin for issuance meta- 500 RVN* Subasset - 100 RVN* Unique asset data, messaging, and transaction meta- 5 RVNdata. 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.
Pay your token holders in RVN=== Restricted Assets ==='''(NEW)''' Restricted assets will be a new kind of assets that come with tags. Turn your profits into RVN and The issuer can send out tags to Ravencoin addresses that tell the entire chain that the asset can go there. The purpose of these restrictions is to all holders limit the transferability of your a token by percentage heldto known good actors, but without revealing the identity of the actors to anyone other than the original entity that verifies their identity. Only when legally required to do so, would the verifier reveal the identity.
Dividend support 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 done without modifying transferred by the protocolissuer. We can add it to a version of the software that Tag tokens can be used sent or revoked only by the payer, without requiring others to upgrade (i.e., a soft fork)Tag issuer.
If you require this functionality ask in #dev channel on discord Restricted assets offer a solution to SEC compliance for security tokens: Ravencoin will allow for appending externally-validated trust from interested parties such as regulators, through intermediate Qualifiers such as there is a python script KYC/AML provider consortia, down to get owners individual addresses. Issuers of assetscan 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 borne primarily by the regulated entities and someone could write code to loop through owners paying to their addressregulators that require such information in the first place.
Broadcast a message to all of your token holders.===Use examples===
Second tier web voting can be built on top of this protocol.

=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 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].

===Global burn address===If you are looking want to port existing Bitcoin applications get rid of for example assets you do not want. You can send them to include Ravencoin - there are some useful parameters available from work done in the [httpsa global burn address://github.com/brian112358/ledger-wallet-chrome/commit/303f5030059c805d808c83466275e078d06afbb5 Ledger integration code on GitHub].
==Phase 2&4 3 - Assets & Unique assets 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.
==Phase 3 - Dividends/Rewards= OIP Integration ==='''(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.

== 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-748158f63e11 == 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.

==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.
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. ===Network call getassetdata()===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, 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. 0 22 - Size of IPFS hash - 34 Bytes 1220da203afd5eda1f45deeafb70ae9d5c15907cd32ec2cd747c641fc1e9ab55b8e8 - IPFS hash data f6010000 - Block height ==IPFS - InterPlanetary File System==You can add a document to an asset as 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. 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. ==Other documentation==Atomic Swapsswaps: https://github.com/RavenProject/Ravencoin/blob/master/doc/atomicswaps.md Issue assets in bulk: https://github.com/RavenProject/Ravencoin/tree/master/assets/tools = 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# 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 {| class="wikitable"! Read this section carefully: BE SAFE AND DON'T CONFUSE YOUR MAINNET WALLET WITH THE TESTNET WALLET! |-| Don't worry, this will not interfere with your regular Raven wallet, just make sure both wallets are not running at the same time. For those who are technically inclined, running in testnet mode does not overwrite any of the blockchain data or wallet files of Ravencoin’s main network. Instead, it will create a subfolder named testnet3 inside your data folder where all testnet related data and wallets reside.
