What is blockchain?

Blockchain is a decentralized, distributed ledger technology that allows for the secure and transparent recording of transactions. It is a digital database that is used to store and record transactions that are made using cryptocurrencies, such as Bitcoin. In a blockchain, each transaction is recorded as a “block” and added to the database in a linear, chronological order. This allows for the creation of a transparent and secure record of transactions that is resistant to tampering and revision.
