How it works?

How it works?
Wallets’ owners create new transaction using secure channel either online or offline Wallet sends transaction to node Transaction is verified by the node Transaction is added to the mining pool Mined blocks containing the new transactions are sent to the known peers Fast sync
Both wallets participate in signing the transaction using Schnorr protocol 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 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. A block is mined every minute and is sent back to the node for verification and distribution. A valid block that is extending the longest chain is accepted as a new Tip and propagated further until full consensus is reached. 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.
