Abstract

The hyperledger fabric is a modular blockchain framework used by private companies to develop blockchain-based products, solutions, and applications using plug-and-play components. Smart contracts running in this framework are created by implementing chaincode for IT Development. When implementing the chaincode, there may be a security weakness that is the root cause of the security vulnerability in the code. If the chaincode with the security weakness is completed and a block is created, the chaincode with the inherent security weakness creates a security threat because the contract cannot be modified arbitrarily.The hyperledger fabric is a modular blockchain framework used by private companies to develop blockchain-based products, solutions, and applications using plug-and-play components.
