Blockchain technology is a distributed database that is used to maintain a continuously growing list of records, called blocks. Each block contains a timestamp, a transaction record, and a reference to the previous block. Once a block is added to the chain, it cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
Blockchain technology is important because it provides a secure and transparent way to record transactions. It is being used in a variety of applications, including cryptocurrency, supply chain management, and healthcare.
