Abstract

The present application provides a blockchain data protection method, apparatus, system and computer readable storage medium, which are applied to the field of blockchain technology. The present application provides a blockchain data protection method, apparatus, system and computer readable storage medium, which are applied to the field of blockchain technology. The method includes: 1) the firstblock chain node performs homomorphic encryption on the encrypted data to obtain the encrypted ciphertext; 2) the first blockchain node uploads a request that calculates the encrypted ciphertext to the blockchain system; 3) the second blockchain node acquires the request from the blockchain system; 4) the second blockchain node acquires the encrypted ciphertext according to the request; 5) the second blockchain node calculates the obtained encrypted ciphertext and uploads the calculation result to the blockchain system. The method can protect the blockchain data and increase calculation and processing efficeincy on the blockchain data.

Description

technical field [0001] The present application relates to the technical field of block chain, and specifically, the present application relates to a block chain data protection method, device, system and computer-readable storage medium. Background technique [0002] In the past 20 years, we have witnessed the rapid development of the Internet, which has brought us great convenience in life. However, Internet applications are becoming more and more centralized, and resources are mostly controlled by large enterprises (such as Google, Facebook, Twitter, etc.). In order to use these applications, users must entrust their private information to the management of enterprises and give them complete trust. The current Internet is rife with identity theft, spam, advertising, hackers, and more. [0003] Blockchain technologies such as Bitcoin and Ethereum provide the basis for building a completely decentralized Internet application. The underlying technology of the blockchain bu...
