A blockchain is structured as a decentralized, distributed ledger that records transactions across a network of computers. Each block in the chain contains a list of transactions, a timestamp, and a reference to the previous block, creating a chronological and immutable record of all transactions. The network of computers, or nodes, work together to validate and add new blocks to the chain through a consensus mechanism, such as proof of work or proof of stake. This structure ensures that the blockchain is secure, transparent, and resistant to tampering or fraud. **
