Embodiment Construction

[0031] Attached below figure 1 and figure 2 , to further describe the specific embodiments of the present invention.

[0032] The embodiment of the present invention discloses a transaction verification method based on block chain and smart contract, such as figure 1 shown, including the following steps:

[0033] S1: The smart contract for constructing transaction authenticity verification is published to the blockchain, and the blockchain is synchronized to each node. The nodes include multiple nodes including e-commerce platforms, payment platforms, and logistics platforms.

[0034] Blockchain (Blockchain) is composed of a series of data blocks generated by cryptographic methods, each block contains the hash value (hash) of the previous block, and is connected from the genesis block (genesis block) to the current block to form a block chain. The blockchain is also a distributed database system involving nodes. It is essentially a decentralized database ledger that recor...

Abstract

A transaction authenticity verification method and system based on block chain and intelligent contract iare disclosed. The method includes: S1. The intelligent contract verified by transaction authenticity is constructed and published to block chain. The node comprises a plurality of nodes including an e-commerce platform and a payment platform as a logistics platform. S2, the e-commerce platform, the payment platform and the logistics platform respectively publish the corresponding transaction records, the payment records and the logistics records as the dynamic transaction data to the blockchain, wherein the dynamic transaction data carries the transaction parameters including the order identification information; S3: the intelligent contract of the node obtains the corresponding orderidentification information according to the dynamic transaction data which meets the verification condition of the authenticity of the starting transaction, finds out the corresponding transaction records, payment records and logistics records through the order identification information, verifies the authenticity of the transaction, and gives the authenticity result of the transaction accordingto the verification result; S4: The block chain synchronizes the transaction authenticity result to each node.

Description

technical field [0001] The invention belongs to the technical field of financial data processing, and in particular relates to a transaction authenticity verification method and system based on block chains and smart contracts. Background technique [0002] With the popularization of computer information technology, especially the widespread use of the Internet, the entire trading activity has also realized electronic operations. The two sides of the transaction often conduct transactions through the Internet without the two parties "meeting each other". The traditional face-to-face exchange or direct face-to-face transaction method is gradually being replaced by e-commerce. E-commerce has the advantages of high efficiency, speed, convenience, no borders, and no time difference. Therefore, it is loved by merchants and has developed rapidly. It has now become an important way of commodity transactions. [0003] The e-commerce model is generally that the buyer places an order...
