Embodiment Construction

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further elaborated.

[0016] The private use authorization method of blockchain digital assets based on zero-knowledge proof of the present invention comprises the following steps:

[0017] User registration steps: users who need to issue digital assets on the blockchain register according to the smart contract;

[0018] Digital asset registration steps: After registration, users register their own digital assets according to the smart contract;

[0019] Digital asset authorization steps: When a registered user needs to anonymously authorize part or all of his registered digital assets to one or more registered users, the registered user generates a token on the blockchain according to the smart contract. Authorization records, and send the generated authorization records to authorized users;

[0020] Authorizat...

Abstract

The invention discloses a private use authorization method for blockchain digital assets based on zero knowledge proof. The private use authorization method comprises the following steps: a user registration step; a digital asset registration step; a digital asset authorization step; and an authorization certification step. According to the invention, the digital assets can be published on the blockchain, but owners of the digital assets are hidden; and meanwhile, the use authorization of the digital assets can be carried out on the chain, but authorized purchasers, owners and digital asset information are hidden.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for authorizing private use of block chain digital assets based on zero-knowledge proof. Background technique [0002] In the blockchain system designed with the UTXO model represented by Bitcoin, the flow of each UTXO is open, and the guarantee of anonymity is realized by hiding the correspondence between the person and the address. Once an address and person The corresponding relationship of the person is exposed, and with some on-chain data analysis tools, basically all the transaction records and funds of this person can be traced. In smart contract blockchains such as Ethereum, although the virtual machine can provide a Turing-complete programming language to implement arbitrary logic, all transaction data in the block is also public. The development of zero-knowledge proofs has led many users to try to realize private transactions on the blockchain. The Night...
