CoinPoker is a worldwide cryptocurrency-based online poker room that’s launching its ICO this November. We’re operating with Ethereum Smart Contracts and once the room will have been launched, we’re going to ensure full transparency via the use of blockchains. The RNG will be visible on blockchains, and the players will be able to see it after the game. That together with the pain-free transactions thanks to cryptocurrency will solve many of the problems that online poker has been facing. • Transactions will be immediate + accessible worldwide; • RnG will be visible for transparency; • Anonymity will be guaranteed; • Fair play at the tables will be ensured. + HUGE Grand Opening Events with awesome prizes (15% of tokens distributed during the ICO will be returned during these tournaments). What makes us different from other ICOs? Well, for one, we’ve got our MVP (minimum viable product, in our case – an app) ready to go, and we’ll be launching our MVP with play money before our actual ICO start!
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.
