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.
Aion is a revolutionary multi-tier blockchain platform that has been created to solve the pressing issue of limited operability between existing blockchains while still remaining capable of handling its own applications. It supports custom blockchain architectures, and it provides cross-chain interoperability. The Aion project comes at a very appropriate period, in a time where there’s an ever-growing number of blockchains.Thus, interoperability is more important now that it ever has been. Interoperability will expand the horizons of multiple other blockchain platforms, not to mention those of enterprise-oriented companies. The project is led by Matthew Spoke, the CEO of Nuco and board member on the EEA. Other big names include Jin Tu, Nuco’s CTO, who has more than 15 years of experience in enterprise engineering and more than four years in the blockchain industry, and Peter Vessenes who has co-founded the Bitcoin Foundation. The token is the blockchain’s power-source. It’s used for securing the network, for creating new blockchains, as well as for monetizing inter-chain bridges. AION token is actually an ERC-20 token. In fact, the token is first offered as an ERC-20 token on the Ethereum blockchain, and only then it can be changed to the official AION network token. When that happens, the token can freely stream between two blockchains. The best thing about this is that investors are not required to change their Aion Ethereum token (ERC-20) for the Aion-1 token, as they will always be interchangeable. In order to buy AION, you will need to first purchase another cryptocurrency, preferably Bitcoin or Ethereum. Fortunately, AION is supported by some very popular crypto exchanges out there such as BitForex, Binance, Ethfinex, Liqui, and Bancor Network. There's a good chance that Aion, with its unique approach of solving interoperability issues, will become somewhat of a necessity for the cryptosphere in the following period.
