The MBC Protocol (Multi-Blockchain Communication) is the cross-chain communication protocol of ME Network, derived from the IBC protocol of the Cosmos network and compatible with its native standards. It supports interconnection and interoperability between ME Network and Rollup chains, multiple Rollup chains, and chains within the Cosmos ecosystem. Core functions include cross-chain data transmission, asset transfer, and contract calls, ensuring security through Byzantine fault tolerance and authentication mechanisms, while supporting unique scenarios such as cross-chain DID message communication.
