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 an authenticable message (AM) associated with a first account to a blockchain associated with the first blockchain network, where the AM is generated based on a protocol stack comprising an outer-layer protocol, a middle-layer protocol, and an inner-layer protocol, the outer-layer protocol comprises an identifier (ID) of an originating blockchain network and the middle-layer protocol, the middle-layer protocol comprises information of the sending account and the inner-layer protocol, the inner-layer protocol comprises an ID of a destination blockchain network, information of a receiving account associated with the destination blockchain network, and message content. The AM and location information is transmitted to a relay to be forwarded to the second account associated with the second blockchain network.
