Embodiment 1
[0065] A dynamic cross-chain message forwarding system, such as figure 1 As shown, it includes message originating chain, relay chain, and message target chain.
[0066] The message originating chain is the originator of cross-chain messages, including multiple blockchain nodes. The message initiation chain node is responsible for sending the cross-chain message to the relay chain node in the corresponding relationship between the inter-chain nodes.
[0067] The relay chain is the relay party of cross-chain messages, including multiple blockchain nodes. The relay chain node is responsible for receiving the cross-chain message from the initiating chain node, verifying the correctness of the cross-chain message, signing the cross-chain message, and broadcasting and aggregating the signature by dynamically dividing the group after signing. After the number of signatures aggregated by nodes reaches the threshold, the aggregated signatures and messages are sent to the nodes corre...
Embodiment 2
[0074] A dynamic cross-chain message forwarding method, such as image 3 shown, including:
[0075] Step 301: Each node of the message initiation chain sends a cross-chain message to the relay chain node. Each node of the message initiation chain selects the relay chain node to send the cross-chain message according to the corresponding relationship between the chain nodes when the message is transmitted between the chains.
[0076] Step 302: The relay chain node receives the cross-chain message from the initiating chain, performs message verification, and signs the message after the verification is passed.
[0077] Step 303: Each node of the relay chain negotiates a consistent random number as a dynamic factor, divides groups based on the dynamic factor, and establishes a corresponding relationship between nodes sending messages between groups.
[0078] Each node negotiates a consistent random number as the dynamic factor.
[0079] In some embodiments, the cross-chain mess...
