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.
Released to the public in 2014, Reddcoin is a decentralized social cryptocurrency that allows anyone to instantly send & receive RDD (its native cryptocurrency) payments on social networks with no transaction fees. It’s essentially the blockchain version of Venmo, Facebook Money, or Snapchat's Snapcash, all of which allow you to easily transfer money to friends and family via their respective social media platforms. However, unlike these major social media networks that require you to use their native platform to send and receive money, Reddcoin allows you to seamlessly integrate its payment features on multiple platforms like Reddit, Facebook, Twitter, and more. Reddcoin is a social cryptocurrency that can be integrated with many different social media platforms for sending/receiving money with zero fees. It’s a peer-to-peer open-source cryptocurrency forked from Litecoin. It dedicates much of its efforts to facilitate the “tipping” of small amounts of RDD on social networks, done in a similar fashion to “liking” a post on FB. The PoSV algorithm is a new take on PoS which encourages both ownership (stake) and activity (velocity). Its tipping system has already been enabled on Twitter, Reddit, Twitch, and Justin.TV. Reddcoin was created on January 20, 2014, as a PoW cryptocurrency. On February 2, 2014, after raising $100,000 through their Initial Public Coin Offering (IPCO), Reddcoin was released to the public. On April 29, 2014, they announced that Reddcoin would transition from PoW to PoSV. In 2017, Reddcoin made an official announcement listing their team members, including developers John Nash and Leonard Simonse. In subsequent Tweets, they’ve publicly announced the additions of developers such as Bradley Ploof and James Tweeg. They’ve been active in updating the community via Twitter, but if you’d like to keep informed directly on the teams project progress, check out their GitHub or Trello (which includes the project roadmap).
