Ravencoin is a blockchain specifically dedicated to the creation and peer-to-peer transfer of assets. Just as Monero is solely focused on privacy, Ravencoin specializes in asset transfer – nothing more, nothing less. Although you can exchange assets over other blockchains, like Bitcoin and Ethereum, that’s not their intended purpose. And the lack of specialization leads to problems that are specific to transferring assets. Ravencoin enables you to create and trade any real-world (e.g., gold bars, land deeds) or digital (e.g., gaming items, software licenses) assets on a network with only that in mind. Ravencoin doesn’t have an established team. It’s an open-source project led by the core developers: RavoncoinDev, Tron, and Chatturga (discord usernames). Bruce Fenton, Board Member of The Bitcoin Foundation, advises the team. The core developers launched Ravencoin on January 3rd, 2018 and Fenton kicked off the launch with a Tweet announcing the start of mining. The project gained some notoriety when Overstock CEO Patrick Byrne announced that his company had made a multi-million dollar investment into the team. Since then, the team has been building out the core functionality of asset support and rewards capabilities. The release of the Ravencoin mainnet and increase in activity on the platform should help the price. Any news of notable companies or financial institutions utilizing the platform should also have a positive effect. Ravencoin offers just one thing: tokenized asset transfer. And that singular focus isn’t a bad thing. When projects attempt to solve a bunch of problems at once, they often create a bunch of half-baked solutions. Ravencoin is avoiding that. As a young project with seemingly endless competition, it’s difficult to predict how successful Ravencoin will be. An active community and backing from one of the most respected names in online retail are positive indicators, though. There’s a clear trend toward the tokenization of all types of assets. However, we have yet to see whether or not Ravencoin will be leading that change.
Beam Mimblewimble is a scalable, fungible, and confidential cryptocurrency based on the Mimblewimble implementation. WHY BEAM? Core features include complete control over your privacy, All transactions are private by default, No addresses or other private information are stored on the blockchain, Superior scalability due to compact blockchain size, Opt-in Auditability, Support online and offline transactions, atomic swap, hardware wallets integration. Governance model No premine, No ICO. Backed by Treasury Establishing a non-profit foundation to govern the protocol after Mainnet launch How does it work? Wallets’ owners create new transaction using secure channel either online or offline Both wallets participate in signing the transaction using Schnorr protocol Wallet sends transaction to node Each transaction contains a list of Inputs and Outputs represented by Pedersen Commitments, as well as explicit fees and kernels. Each transaction also contains non-interactive zero knowledge range proof to verify that the output transaction value is positive Transaction is verified by the node Each transaction is verified with respect to the recent blockchain state which is stored as a Merkle Tree. The root hash of the tree is recorded in block header along with a proof of work. In addition, each node periodically creates compacted history to allow ‘fast sync’ of new and existing nodes. Transaction is added to the mining pool A block is mined every minute and is sent back to the node for verification and distribution. Mined blocks containing the new transactions are sent to the known peers A valid block that is extending the longest chain is accepted as a new Tip and propagated further until full consensus is reached. Fast sync When a new node connects to the network for the first time it can request compacted history containing only system state and blockchain headers. There is no need to retrieve the entire transaction history.
