A blockchain is a decentralized, distributed digital ledger that records transactions on multiple computers in a secure and transparent way.
Each block in the chain contains a cryptographic hash of the previous block, a timestamp, and transaction data. Once a block is added to the chain, it cannot be modified or deleted.
This creates a tamper-proof system that can be used to securely and transparently record and verify a wide range of transactions, from financial transactions to supply chain management to voting.

A blockchain is a decentralized, digital ledger that records transactions in a secure and transparent manner. It uses cryptography to ensure the integrity of the data and is maintained by a network of computers. It is often associated with cryptocurrencies like Bitcoin but has many potential applications beyond that.
