The Raven is a highly symbolic creature that is mentioned in a variety of cultures with varied purposes . One of the meanings is that of transformation.
As Ravencoin is a fork of the Bitcoin code it could very well be this meaning that the developers wanted to express. It is with this imagery that we introduce Ravencoin.
Ravencoin is a new project that was announced on October 31st, 2017 and debuted on Bitcoin’s 9th birthday on January 3rd, 2018 with the release of software for mining.
Ravencoin is more than a fork of the Bitcoin code it is a project that builds upon the original vision of Bitcoin but with added new features which extend the functionality and the intrinsic value of the coin organically.
Ravencoin: Clone of bitcoin that will be used for assets. Improved bitcoin built for assets
Ravencoin is a free open source platform designed for the specific use case of transferring assets such as token-backed assets from one holder to another.
While it may seem that with the development of the great blockchains such as Bitcoin and Ethereum, transferring assets between different parties is already a solved issue, it is not exactly the case. Neither Bitcoin nor Ethereum were specifically designed for facilitating ownership of additional assets, do to the fact that they simply focused their attention in other features.
Ravencoin is built on a fork of the Bitcoin code. It has been implemented with a smaller block reward of one minute (the block reward is the only way that new coins are created and it is an incentive for miners to add hash power to the network), and the addition of asset creation and message capabilities.
If you are a crypto-lover, and we are sure you are because you are reading this right now. You will agree that blockchain tech will indeed change global economic paradigm as we know it nowadays.
However being able to send wealth transactions in a matter of seconds, internationally and with no third parties involved, is just the tip of the iceberg that this new revolution represents.
In the same path of unstoppable evolution, Ravencoin will implement the way assets owners operate with their wells. It will allow them to handle efficiently the transfer of their assets to another parties.
To live this world order revolution without losing any keypoint:
Despite the success and widespread adoption of Bitcoin and Ethereum, neither of these blockchains have been specifically designed to facilitate the ownership of additional assets on top of the tokens that are transacted throughout their respective networks.
In Bitcoin, the original rules governing the blockchain and protocol must be adhered to and so this means that Bitcoin nodes are not able to register that assets are being embedded into tokens.
This means that for every asset transaction made on the Bitcoin network, there must be an accompanying bitcoin transaction fee, even if the transaction is to simply send the asset.
This has a result of unnecessary transaction fees whenever assets are transferred. Additionally, the other major disadvantage is that assets can easily be ‘destroyed’ if they are sent to an exchange or wallet.
For Ethereum the network is not able to natively recognize smart contract tokens and this can cause some confusion due to multiple ERC20 tokens with identical names. The only distinguishing factor between contracts with identical names is the contract hash and this can confuse users or be used with malicious intent to scam others.
As Ravencoin will be running on a decentralized model with independent miners to support the stability of the blockchain combined with ASIS-resistance the coin will have a good chance of staying in the hands of individuals and not centralized by one party or a group of parties that can collude to shape the outcome of an event, a vote or even the price of the coin itself.
The solution to the above issues is to create a Bitcoin-like system that is completely asset aware so that it recognizes when tokens have been designed as assets.
With a view to solve the problem, Ravencoin will bring to life the said:
“Keep it simple stupid”
by focusing on creating one thing, just one specific thing… a bitcoin-like system , totally aware about when tokens are designed as assets (Based on PoW but with a new mining algorithm, x16r).
This provides three advantages:
Ok, now we understand the problem (the proposed one, between the many existing issues) that needs to be solved in current blockchain and we know the solution that Ravencoin is committed to develop in order to transcend that limitation.
So… whats next?. We need to go deep into their tech… it seems boring, but we will take care of that. Only in that way we will really have knowledge and foundations to take decisions about the project.
Ravencoin bring us the following features:
Before we describe what X16R is we will first provide details behind what other coins have implemented for their algorithms.
In the search to create and implement algorithms that are ASIC resistant (meaning that purpose built mining machines with high hash rates could not be developed) which in turn reduces the chances of centralization via large mining farms, projects have tried a variety of tactics to hinder this centralization (like we see with Bitcoin mining).
The first approach was to adopt memory intensive algorithms like those used by both Scrypt and Equihash. This requirement for additional in memory calculations reduces the performance of the ASIC to more onpar of the GPU based mining with the same algorithm
Another approach that was undertaken, was Dash’s approach, which was to adopt the X11 algorithm. This is the use of 11 chained hashing algorithms (hence the name) in an effort to slow down the creation of ASIC hardware.
This did not prevent the design of a special purpose ASIC so once there was an ASIC for X11, others added more hashing algorithms to create additional algorithms that were named X13, X15 and X17. This makes it more difficult to create an ASIC but because the algorithms are in roughly the same order its difficult but not impossible to create an ASIC.
What Ravecoin is doing is called X16r and that implementation like the others described previously use 16 algorithms for the hashing (see table below). The key difference is they have added algorithm reordering. It is this reordering based on the results from the previous block that provides more ASIC resistance than other hashing algorithms.
Previous Block Hash: 0000000000000000007e8a29f052ac2870045ae3970270f97da00919b8e86287
The final 8 bytes: 0x7da00919b8e86287 determines what the next 16 hashes should be.
Phase 1 — Complete
Ravencoin (RVN) is a Proof of Work coin built on the Bitcoin UTXO model. As with other Bitcoin derivatives, RVN coins are distributed to persons augmenting the Raven network by mining Raven.
UTXO — UNSPENT TRANSACTION OUTPUT DEFINITION
The Unspent Transaction Output is key to bitcoin as this is how bitcoin keeps track of inputs and outputs on the blockchain. First let’s look at how a bank works.
Assume Tom is with Bank A and has a balance of $5,000 and assume that Alice who does all her banking with Bank B has no balance.
Tom wants to send $2,000 dollars to Alice. To do this Tom asks his bank to send $2,000 to Bank B in Alice’s name.
The actual transaction has Tom’s balance reduced by $2,000 from $5,000 to $3,000 and Alice’s balance increases from $0 to $2,000.
Taking this to the Bitcoin blockchain:
Tom has received inputs in the amount of 5 BTC. This is from 4 transactions (inputs)
In this example, Tom wants to send Alice 2 BTC. The blockchain, unlike banks, is not aware of balances as in the example above so the transaction is recorded as :
Phase 2 — Assets (in progress)ASIC RESISTANCE
ASIC Resistance — A published commitment to continual attempts at ASIC resistance. If ASICs are created for x16r, then we will, at a specific block number, modify one of the algorithms to add Equihash, EthHash or similar efforts to increase the resistance to ASIC miners for Raven.
UNIQUE ASSET SUPPORT
Ravencoin will be a hard fork that extends Raven to include the ability to issue and transfer assets. The expected release of asset capabilities will be approximately seven months after the release of RVN. Raven will be extended to allow issuing, reissuing, and transfer of assets. Assets can be reissuable or limited to a set supply at the point of issuance.
The cost to create assets will be 500 RVN to create any qty of an asset. Each asset name must be unique. Asset names will be limited to A-Z and 0–9, ‘‘ and ‘.’ and must be at least three characters long. The ‘.’ and the ‘‘ cannot be the first, or the last character, or be consecutive.
Examples of valid assets:
Examples of invalid assets:
A..B (consecutive punctuation)
The RVN used to issue assets will be sent to a burn address, which will reduce the amount of RVN available.
Asset transfers require the standard RVN transaction fees for transfer from one address to another.
Metadata about the token can be stored in IPFS. Initially this cannot be changed. If there is a demand, the system can be updated to allow updating the metadata by the token issuer.
Reward capabilities will be added to allow payment (in RVN) to all holders of an asset. Payments of RVN would be distributed to all asset holders pro rata. This is useful for paying dividends, dividing payments, or rewarding a group of token holders.
Example: A small software company issues an asset GAMECO that represents a share of the project. GAMECO tokens can be traded with others. Once the software company profits, those profits can be distributed to all holders of GAMECO by sending the profits (via RVN) to all holders of GAMECO.
Raven may increase the blocksize from 1 MB to X MB to allow for more on-chain transactions.
Phase 3 — Rewards
The reward system will allow for the creation of tokens that sit on the Raven blockchain. These tokens can be created and then sent to people as a reward for doing something or as a way to raise funds. The funds raised can then be used to send any currency on the raven blockchain to another party.
Phase 4 — Unique Assets
Once created, assets can be made unique for a cost of 5 RVN. Only non-divisible assets can be made unique. This moves an asset to a UTXO and associates a unique identifier with the txid. From this point the asset can be moved from one address to another and can be traced back to its origin. Only the issuer of the original asset can make an asset unique.
The costs to make unique assets will be sent to a burn address.
Some examples of unique assets:
Phase 5 — Messaging
Messaging to token holders by authorized senders will be layered on top of the Phase 3 unique assets. See KAAAWWW Protocol for additional information.
Phase 6 — Voting
Voting will be accomplished by creating and distributing parallel tokens to token holders. These tokens can be sent to RVN addresses to record a vote.
Dubbed a community coin. Anyone can contribute and add to the project.
The number of developers involved is uncertain, however there were 430 Bitcoin developers who made over 14,000 commits according to Github.
