What’s Blockchain Technology?


Blockchain technology is a type of Distributed Ledger Technology (DLT). A distributed ledger is a database to record, shares, and synchronize digital data. This database is shared and duplicated across a network of computers. Those participating in the network can update the data or records in the ledger. It operates without the need for a central authority.

Blockchain organizes data into blocks chained together in an immutable form. Blockchain uses decentralization and cryptographic hashing. This helps in making the history of any digital asset unalterable and transparent.
