Problems solved by technology

[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 without much consideration for privacy
Common encryption technologies to solve privacy problems, such as Homomorphic encryption and zero-knowledge proof, have high complexity, poor versatility, and may cause serious performance loss

Abstract

One or more embodiments of the present specification provide a method and node for realizing contract calling in a block chain and a storage medius. The method comprises that a first block chain nodeexecutes a plaintext-type smart contract in a trusted execution environment to determine a smart contract called by the plaintext-type smart contract; when the called smart contract is a privacy type,the first block chain node decrypts the called smart contract; the first block chain node determines a calling condition of the called smart contract; and when the calling condition is met, the firstblock chain node executes the called smart contract in the trusted execution environment.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular to a method, node, and storage medium for implementing contract invocation in the blockchain. 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. Nodes in these blockchain networks sometimes need to be increased. [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...
