Abstract

The Hyperledger Fabric or smart contracts in blockchain are generally designed for the purpose of common coding languages that are notable by probable developers and coders, like Golang. Because of the loopholes in developing improvement particulars for smart Contracts utilizing all-purpose coding language, there exists frequently occurred risks related to hyperledger fabric. It will promote numerous problems and possible security risks to the clients after the smart cards are being circulated into hyperledger fabric. In spite of the fact that there already exists some possible risk identification methodologies for Hyperledger Fabric, the precision and inclusion of the methodologies are restricted. In reaction to such issues, this paper sums up three sorts of expected risks in the Hyperledger’s smart contract: Logical Security, Non-deterministic, and Security of Personal Data. To identify such kinds of possible risks, a static strategy of analysis which is centered on FD (Functional Dependency) and AST (Abstract Syntax Tree) has been proposed in the paper. Simultaneously, an identification framework that can precisely find the area of possible risks in the Hyperledger Fabric’s smart contract is designed to produce advancement ideas for the recommendation of the developers of smart contracts.
