Alliance chain multi-chain system based on Snowman consensus and interaction and deployment method thereof

The invention provides a Snowman consensus-based alliance chain multi-chain system and an interaction and deployment method thereof, and the system comprises a platform chain of a main network, a contract execution chain, a subnetwork, a verifier module, and a Snowman consensus module. According to the method, a transaction is verified by using the Snowman consensus, all nodes in the network do not need to reach the consensus, and only a part of nodes need to be verified successfully. And the verification efficiency of the network cannot be reduced due to increase of the number of nodes. On the basis of a Snowman consensus protocol, it is verified that one sub-network can be added into a plurality of different sub-networks, so that sharing security can be achieved among the sub-networks, and the TPS of the whole alliance chain system architecture can be infinitely expanded while the block chain of the user can be customized and the number of chains can be transversely expanded according to user requirements.
