Blockchain technology is an easily accessible distributed data management system in which blocks linked in a chain that keep tamper-proof transaction records. Unlike other databases, it includes different technological systems such as peer to peer network, distributed ledger, cryptography, consensus mechanism and smart contract. While blockchain brings visibility, security, trust environment and transparency to the supply chain of companies to ensure sustainability, on the other hand, blockchain innovations come together with emergent technologies to provide scalable data management, decentralized networking, automation, predictive performance, real-time traceability that significantly affect productivity and profitability. While this study addresses about the shortcomings of the existing supply chain and improvements coming from blockchain technology to the supply chain, it also focuses on the structure of blockchain technology, how it works, where it is used and future predictions of it.
