Patent attributes
Disclosed herein are computer-implemented methods; computer-implemented systems; and non-transitory, computer-readable media, for sending cross-chain messages. One computer-implemented method includes storing, through consensus of blockchain nodes of a first blockchain network, an authenticable message (AM) associated with a first account to a blockchain associated with the first blockchain network, where the AM comprises an identifier of the first blockchain network, information of the first account, information of a recipient of the AM, and content of the AM. The AM and location information is transmitted to a relay to be forwarded to the recipient located outside of the first blockchain network, where the location information identifies a location of the AM in the blockchain and the recipient includes one or more accounts outside of the first blockchain network.
