A blockchain is a decentralized, distributed ledger technology that records transactions across a network of computers. Each transaction, or "block," is securely linked to the previous one, forming a chain of blocks. Blockchains are immutable, transparent, and secure, making them ideal for recording transactions and data in a tamper-proof manner.

A blockchain is a decentralized, distributed ledger technology that records transactions across multiple computers in a way that is secure, transparent, and resistant to modification. It is most commonly known as the technology behind cryptocurrencies like Bitcoin, but it has applications beyond digital currencies, such as supply chain management, voting systems, and identity verification.
