What is a blockchain technology?

Blockchain technology is a digital ledger that stores data in a decentralized, distributed, and immutable public network. It is used to record and track transactions securely, including financial transactions, contracts, assets, or any other form of valuable data. It works as a peer-to-peer network, which means users can view and access the same data across the entire network. All participants in the network can not only see past transactions but also authorized changes to these records.
