Abstract

This application is applicable to the field of blockchain technology, and in particular relates to a verification method, device, relay chain node and medium for cross-chain transaction supervision. The method obtains the relay ciphertext and the first supervision ciphertext, and decrypts the relay ciphertext in the trusted execution environment to obtain the transaction key, and then encrypts the obtained transaction key to obtain the second supervision ciphertext, Perform the first verification on the second regulatory ciphertext and the first regulatory ciphertext. If the verification is passed, send the first regulatory ciphertext and transaction ciphertext to the regulator. Since the regulator obtains the transaction key through the first regulatory ciphertext, Therefore, verifying the first supervision ciphertext sent by the transaction initiator before the cross-chain transaction can ensure the authenticity of the first supervision ciphertext, effectively realize the supervision of cross-chain transactions, and avoid the occurrence of illegal transactions.

Description

technical field [0001] The present application belongs to the field of blockchain technology, and in particular relates to a verification method, device, relay chain node and medium for cross-chain transaction supervision. Background technique [0002] At present, different application systems are configured with different blockchains, and data interaction between different blockchains is usually required due to business requirements. Data interaction between different blockchains is usually called cross-chain transactions. In the cross-chain transaction, the transaction information is encrypted by the transaction key agreed upon by both parties. Therefore, the third party cannot obtain the transaction information. At this time, if the regulator wants to supervise the cross-chain transaction, the transaction initiator needs to provide the transaction to the regulator. key, so that the supervisor can decrypt the ciphertext of the transaction to obtain the transaction informat...
