Blockchain is a decentralized digital ledger that allows for secure and transparent peer-to-peer transactions without the need for intermediaries such as banks or government institutions. It consists of a chain of blocks that contain transactional data and are linked together using cryptographic techniques to ensure immutability and tamper-proofing. Each block contains a unique code, or hash, that is created based on the data it contains and the hash of the previous block in the chain, creating a continuous and unbroken record of transactions. This technology has the potential to revolutionize many industries, including finance, healthcare, and supply chain management, by enabling faster, more secure, and more efficient transactions.
