Problems solved by technology

The former often needs to deploy a new blockchain network for each privacy contract logic, which consumes a lot of money; although the latter only needs to deploy a blockchain network, the authority control logic is more complicated

Abstract

The invention discloses a method for protecting a privacy contract based on an alliance block chain. The method defines a set of API interfaces dedicated to privacy contracts in the block chain platform, and the user of the block chain platform calls the API interface to the transfer node. Initiate the deployment of a privacy contract and various operation requests. After the transfer node is responsible for synchronizing the request to all designated participant nodes, the transfer node will reconstruct a public transaction, and then the public transaction will pass through the normal block The on-chain process is recorded in the public ledgers of all blockchain nodes. Finally, the participants in the privacy contract will also record the corresponding privacy contract requests in their respective privacy ledgers, and execute the contract logic to update the privacy ledgers in their respective privacy ledgers. state. This method realizes contract-level privacy protection and enriches the diversity and scalability of privacy protection in the blockchain system.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a privacy contract protection method based on alliance blockchain. Background technique [0002] Blockchain technology is essentially a decentralized distributed ledger database. The nodes in the blockchain collectively maintain a reliable and consistent copy of the database in a decentralized manner. In layman's terms, blockchain technology refers to a way for all people to participate in bookkeeping. The transaction confirmation on the blockchain is completed by all nodes on the blockchain, and the consensus algorithm ensures its consistency. All nodes maintain a public The public ledger is visible to any node on the blockchain, thus ensuring that it cannot be forged and tampered with. [0003] A smart contract is a computer protocol designed to disseminate, verify or enforce a contract in an informational manner, automatically executed by a computer system. Smart contracts a...
