Blockchain is a digital ledger technology that allows for the creation of a
decentralized and secure database. In simple terms, it is a system for recording and
storing data that is difficult to hack or alter.

In a blockchain network, multiple participants or nodes maintain an identical copy of the
ledger, which is updated and verified through a consensus mechanism. This means that
each transaction is recorded and validated by the network, and once it is confirmed, it cannot
be altered or deleted.

The data stored on a blockchain can be anything from financial transactions to digital
identity information or even medical records. The most well-known application of
blockchain technology is Bitcoin, a decentralized digital currency that allows for secure and
anonymous transactions
