Blockchain technology has emerged as a transformative tool for industries seeking enhanced transparency, security, and trust in multi-party transactions. Beyond its origins in cryptocurrencies, blockchain (particularly through smart contracts) enables automated, tamper-resistant agreements that minimize the need for central intermediaries. However, practical integration of blockchain into enterprise environments poses challenges related to scalability, regulatory compliance, data privacy, and interoperability with legacy systems. This thesis focuses on Hyperledger Fabric, a leading permissioned blockchain framework designed to meet the stringent requirements of industrial applications. We provide a systematic analysis of Fabric’s architecture, emphasizing its modular structure, robust identity management, and support for customizable smart contracts (chaincode).
