To overcome the challenging problem of the inability of hashed timelock contract to realize cross-chain asset transfers, an improved cross-chain protocol based on miners is proposed. The protocol incorporates elliptic curve cryptography during the atomic swap process, enabling miners to generate and lock transactions on the target chain, thereby completing cross-chain asset transfers. Additionally, a competitive selection algorithm and a reward-punishment algorithm for miner nodes are integrated into the protocol to implement a new proof-of-coin-trust consensus mechanism. Finally, the protocol’s smart contracts and their functional capabilities are described in detail. Simulation results based on Ethereum show that cross-chain asset transfer is safely completed, and honest miners are motivated to actively participate in cross-chain transactions.
