Blockchain is a decentralized digital ledger that is used to record transactions in a secure and transparent way. It is essentially a chain of blocks that contain information about transactions, and is maintained by a network of computers rather than a single central authority. 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 altered without also altering all subsequent blocks, making the blockchain extremely secure and resistant to tampering.
The decentralized nature of the blockchain makes it particularly useful for transactions that require trust between parties who do not necessarily know or trust each other. Blockchain technology is most commonly associated with cryptocurrencies such as Bitcoin, but it has potential applications in a wide range of industries including finance, supply chain management, and even voting systems
