The invention discloses a cross-chain transaction supervision method, device and equipment and a storage medium. The cross-chain transaction supervision method comprises the steps of: calling a first gateway to obtain a supervision public key and cross-chain information of a cross-chain transaction, and randomly generating a transaction key; calling the first gateway to generate cross-chain transaction information according to the transaction key, the supervision public key and the cross-chain information, and sending the cross-chain transaction information to a relay chain, wherein the cross-chain transaction information comprises zero-knowledge proof information and supervision information; and calling a relay chain to verify the zero-knowledge proof information, if the verification is passed, calling a supervision terminal to obtain supervision information, decrypting the supervision information to obtain a decryption result, and supervising the cross-chain transaction information according to the decryption result. According to the cross-chain transaction supervision method and the device, the relay chain is called to verify the zero-knowledge proof information, and after the verification is passed, the supervision terminal is called to decrypt the supervision information, so that the authenticity of the transaction key can be ensured on the premise of not leaking the transaction key, and the effective supervision of the cross-chain transaction is further realized.
Description
technical field [0001] This application relates to the technical field of blockchain, and specifically relates to a cross-chain transaction supervision method, device, equipment and storage medium. Background technique [0002] Technically, blockchain is a decentralized database and distributed ledger technology. From a commercial perspective, it is a value network. The more effective nodes connected in this value network and the wider the distribution, the greater the value superposition that may be generated. Cross-chain technology is the key to realizing the value network. The most basic meaning of cross-chain is to realize the circulation of value and solve the problem of value islands between different chains. [0003] In the application scenario of cross-chain transactions, it is usually necessary to verify the validity of the initiated cross-chain transaction, that is, to verify the signature of the cross-chain transaction. In the cross-chain transaction signature ve...
