Blockchain gained popularity with the popularity of cryptocurrency. Blockchain is the technology behind cryptocurrency. It is a digital decentralized, public ledger of all cryptocurrency transactions. Blockchain is set of completed blocks which are continuously growing and is recorded as per the transaction.
Originally developed as the accounting method for the virtual currency Bitcoin, blockchains - which use what's known as distributed ledger technology (DLT) - are appearing in a variety of commercial applications today.
The blockchain is perhaps the main technological innovation of Bitcoin. Bitcoin isn't regulated by a central authority. Instead, its users dictate and validate transactions when one person pays another for goods or services, eliminating the need for a third party to process or store payments. The completed transaction is publicly recorded into blocks and eventually into the blockchain, where it's verified and relayed by other Bitcoin users. On average, a new block is appended to the blockchain every 10 minutes, through mining.
