In the 21st century, technology and business have become intertwined, leading to the emergence of blockchain technology as a key player in various industries. One sector that has seen a major shift due to blockchain is supply chain management. This article looks at the impact of blockchain on supply chains, exploring the mechanisms behind this transformation and the advantages it brings to businesses around the world. Blockchain, which was initially developed as the underlying technology for Bitcoin, is a digital ledger system that records and stores data in a secure and transparent manner. It is decentralized, meaning that it is not controlled by any single entity, and it is immutable, meaning that the data stored in it cannot be changed or tampered with. By using blockchain technology, businesses can streamline their supply chain processes, making them more efficient and secure.
