Hypeleger Fabric Smart Contract Vulnerability Detection Technology: An Overview

Abstract

Smart contracts are one of the most successful applications of blockchain technology, providing the foundation for a wide range of real-world blockchain applications and occupying a crucial position within the blockchain ecosystem. Hyperledger Fabric, as a influential permissoned blockchain system, warrants in-depth research into the security of its smart contracts. This paper begins by elucidating the sources of security threats to Hyperledger Fabric smart contracts, detailing specific security threats in terms of language inconsistency, external inconsistency, read-write logic, and system security. Subsequently, it provides an overview of research progress in smart contract vulnerability detection techniques, covering feature code matching, symbolic execution, fuzz testing, and intermediate code representation. Based on existing work, it summarizes current methods for detection and evaluation. Finally, drawing upon the summary of existing research efforts, it discusses the challenges faced and potential avenues for future research in the domain of Hyperledger Fabric smart contract vulnerability detection.Related research also facilitates the extension to other heterogeneous permissioned blockchains.
