Abstract

The invention discloses a secure transaction execution method based on a smart contract. The method comprises the following steps: deploying a blockchain node service; receiving the original transaction voucher information for uplink storage; enabling each transaction processing node to sign a smart contract and deploy the smart contract to the blockchain; recording the encrypted transaction voucher information on a transaction data alliance chain based on the smart contract; judging whether a contract is deployed on a blockchain for a current smart contract, analyzing transaction parameters corresponding to the smart contract, checking the identity compliance, security and authority of the transaction parameters of the smart contract, packaging the smart contract, and enabling an execution end to call the smart contract and execute the smart contract; sending the effective consensus information to other transaction processing nodes, determining that the smart contract is effective, and performing uplink evidence storage. According to the invention, the information security is ensured, the requirements of the bank for transaction checking and account checking and clearing are met, the processing efficiency of each link in the transaction process is improved, the default risk caused by human factors is reduced, and the cost reduction and benefit increase of an industrial chain are promoted.

Description

technical field [0001] The content of the present invention relates to the field of computer technology, in particular to a smart contract-based secure transaction execution method. Background technique [0002] "Blockchain" may refer to any of several types of computer-based electronic distributed ledgers. They include consensus-based blockchain and transaction chain technologies, permissioned and permissionless ledgers, shared ledgers and their variants. A blockchain is a peer-to-peer electronic ledger implemented as a computer-based decentralized distributed system consisting of blocks, which in turn consist of transactions and other information. In some examples, a "blockchain transaction" refers to an input message that encodes a structured set of field values ​​including data and conditional sets, where the fulfillment of the conditional set is a prerequisite for writing the field set into the blockchain data structure . Each block contains the hash of the previous ...
