Blockchain

Blockchain is a distributed digital ledger technology that securely records and verifies transactions across multiple computers in a network. Each transaction is grouped into a block, which is linked in chronological order to the previous block, forming a chain. This structure ensures transparency and immutability, as once a block is added to the chain, it cannot be altered without the consensus of the network. Blockchain eliminates the need for a central authority by enabling peer-to-peer transactions, where participants can verify and validate information independently. It is most commonly associated with cryptocurrencies like Bitcoin, but its applications extend to various sectors, including supply chain management, healthcare, finance, and more, where secure and transparent transaction records are essential.
