I've been hearing a lot about blockchain lately. Can you explain what it is?

Blockchain is an immutable digital ledger that records transactions in a secure, decentralized way. It's made up of blocks of data that are linked together using cryptography and stored on a network of computers. Each block contains a timestamp, transaction details, and a link to the previous block. This makes it virtually impossible to tamper with or corrupt any data stored within the chain. The technology behind blockchain has many potential applications, such as cryptocurrency payments, smart contracts, and supply chain management.
