Amoveo (VEO) is a highly scalable proof-of-work blockchain driven by its community and aimed for prediction markets, investment and insurance contracts, and various derivatives, such as stable coins. Amoveo is a blockchain meant for enforcement of investment and insurance contracts. Amoveo contracts are enforced using state-channels. This means fees are low, contracts are nearly instant and can support a global audience. Amoveo has oracle technology. Amoveo can learn facts about our world and enforce the outcome of contracts that are governed by these facts. This, for example, enables you to bet on the price of Amazon shares. The variables that define how to participate in Amoveo can be modified by the Amoveo community using a built-in process. This way Amoveo will always stay optimally tuned to produce the best results.
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.
