Abstract

The invention provides a supply chain transaction privacy protection system based on a block chain. The system comprises core enterprise node equipment used for encrypting payable amount committed bya core enterprise to a first-level supplier to obtain a confidential transaction, signing the confidential transaction and uploading signed transaction data to a supply chain platform based on the block chain; first-level supplier node equipment used for receiving the confidential transaction, decrypting the confidential transaction and outputting the decrypted confidential transaction to the first-level supplier; and a supply chain platform which is based on the block chain and is used for storing the transaction data. The invention further provides a supply chain transaction privacy protection method based on the block chain, block chain node equipment and a storage medium. According to the invention, the plaintext payable amount of the core enterprise can be encrypted into the confidential transaction and uploaded, only two transaction parties can decrypt the amount of money in the confidential transaction, and the transaction privacy is protected from being leaked.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain-based supply chain transaction privacy protection system, method and related equipment. Background technique [0002] The existing blockchain-based supply chain system connects core enterprise node equipment, supplier node equipment, factoring business node equipment, and bank node equipment through blockchain. When core enterprise node equipment, supplier node equipment, factoring business node equipment, and bank node equipment join the blockchain-based supply chain system as blockchain nodes, they need to be authorized to join. The credibility of the data is enhanced through the chaining of transaction data such as accounts receivable, bill certificates, and mortgaged goods certificates. [0003] However, there are often commercial secrets in these transaction data, and the clear text of the transaction data is uploaded to the chain, resulting in the d...
