Abstract

The invention discloses a supply chain transaction privacy protection system based on a block chain, and the system comprises core enterprise node equipment which is used for encrypting payable committed by a core enterprise to a first-level supplier to obtain a confidential transaction, and uploading signed transaction data to a supply chain platform based on the block chain; first-level suppliernode equipment used for performing range certification on split transactions in confidential transactions based on a supervisible Bulletproof algorithm, and sending an obfuscation request to the obfuscation service provider node equipment; obfuscation service provider node equipment which is used for obfuscating the split transaction into other transactions equivalent to the split transaction based on a supervisible proving obfuscation algorithm; a supply chain platform based on the block chain used for storing the received transaction data; and supervision mechanism node equipment used for tracking confusion of the transaction data. The invention further provides a supply chain transaction privacy protection method based on the block chain and related equipment. According to the invention, transaction privacy can be protected from being leaked, and transaction supervision is realized at the same time.

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...
