Blockchain

Blockchain is a decentralized and distributed digital ledger technology that records transactions across multiple computers in a way that ensures the recorded data cannot be altered retroactively without the consensus of the network participants. Each transaction is stored in a “block,” which is linked to the previous block, forming a “chain.” This structure provides transparency, security, and integrity, as it allows participants to verify and audit transactions without the need for a central authority. Blockchain is often associated with cryptocurrencies like Bitcoin but has potential applications in various fields, including supply chain management, healthcare, finance, and more, due to its ability to provide a secure, immutable record of transactions and information.
