Method and device for realizing privacy block chain based on FPGA

Abstract

One or more embodiments of the invention provide a method and a device for realizing a private blockchain based on an FPGA. The method comprises the following steps: a client deploys a circuit logic configuration file to an FPGA structure at a blockchain node, wherein the circuit logic configuration file is used for enabling the FPGA structure to be realized as a trusted execution environment of the blockchain node; the client receives an authentication result returned by the FPGA structure, the authentication result is signed by an authentication root key deployed in the FPGA structure, and apublic key corresponding to the authentication root key is public; and the client confirms that the circuit logic configuration file is successfully deployed on the FPGA structure under the conditions that the authentication result passes signature verification and the authentication result contains content related to the circuit logic configuration file.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular to a method and device for implementing a privacy blockchain based on FPGA. Background technique [0002] Blockchain technology is built on top of transmission networks such as peer-to-peer networks. Network nodes in the transmission network use chained data structures to verify and store data, and use distributed node consensus algorithms to generate and update data. [0003] At present, the two biggest challenges in the technology of enterprise-level blockchain platforms are privacy and performance, and it is often difficult to solve these two challenges at the same time. Most solutions trade for privacy by losing performance, or pursue performance with little regard for privacy. Common encryption technologies to solve privacy problems, such as Homomorphic encryption and zero-knowledge proof, are highly complex, poor in versatility, and may...
