What is Blockchain?

Blockchain is a type of database. Distributed and shared. Information is stored in blocks linked with cryptography.

 Blockchains used for tokens and coins are decentralized. That means that no single person can take control of it.

It can be controlled only collectively.

 Commonly, blockchains are used as a ledger for transactions.

Information added to the blockchain is permanently recorded and irreversible.
