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.
What is DAG? In more traditional blockchains, the host provides the food/drinks (i.e resources) for this party. And when the guests arrive, the amount of resources can only accommodate so many people, the portions are small and then everything eventually runs out and the party ends. Think Constellation DAG like a potluck (a party where everyone brings food/drinks). With every added guest (node to the network), the more resources the party has to keep going. This is the nature of Constellation, a distributed system that scales horizontally. Is Constellation a Blockchain? Not exactly. Although inspired by the principles of decentralization, many standard blockchains such as Bitcoin and Ethereum face scalability issues. This is why the next, generation of decentralized networks such as Hashgraph, IOTA, and Constellation have turned to DAG. What is a Microservice? “Microservices” is an approach to application development in which a large application is built as a suite of modular services. Each module supports a specific business goal and uses a simple, well-defined interface to communicate with other sets of services. Uber, for example, is not a singular app purse. It is a unified app which means it is a single interface that brings together their driver app, their rider app, and their corporate team app.
