A blockchain bridge is a connector that connects two homogeneous or heterogeneous blockchains to allow data, value, and assets to flow across blockchains. The Wanchain bridge solution is implemented via Storeman nodes. A Storeman mechanism is a component node that is used to listen to events on multiple blockchains and processes and relays the transaction to the corresponding blockchains. A storeman node may have multiple running programs to form a cluster and each shares part of the secret for unlocking the accounts that stage the cross-chain values. The storeman mechanism will support staking that allows users to lock a portion of their assets through a smart contract to fund the running node and receive a reward for the cross-chain transaction.
