"Spark Chain Network", a new blockchain infrastructure led by the China Academy of Information and Communications Technology, and AntChain jointly announced that the blockchain domain name service system (BCDNS) and relay service (Relayer) developed in cooperation between the two parties have been open sourced, and developers can directly access these resources through the GitHub community. BCDNS blockchain domain name service can be regarded as a digital identity system used to bind unique identities between different chains; while the relay network is the core role of blockchain cross-chain communication, responsible for securely and reliably delivering messages from the source chain to the target chain.

In the future, "Spark Chain Network" and AntChain will continue to explore and research different heterogeneous chain security cross-chain mechanisms based on the IEEE-P3205 standard in the cross-chain field. Based on the characteristics of different heterogeneous chains, the security authentication mechanism of their on-chain messages will be realized (such as SPV verification, endorsement signature verification, message consensus signature, etc.) to solidify the foundation for trustworthy authentication of cross-chain messages under heterogeneous chains.
