Blockchain-based smart contract calling method and apparatus, and electronic device

摘要

Based on the blockchain, a target transaction containing call data used to initiate a call of a smart contract is received, and at least a portion of the call data is a data digest of the target data stored in a third-party storage system interconnected with the blockchain. digest). Target data corresponding to the data digest is queried from a third-party storage system. Query results containing encrypted target data returned by the third-party storage system are received. A key used to decrypt the encrypted target data is obtained, and the encrypted target data is decrypted based on the key. Content verification is performed on the decrypted target data. If the verification is successful, the smart contract is invoked to perform smart contract calculations on the calling data. After the smart contract calculation is completed, the calculation result is stored in the distributed database of the blockchain.
