# Basic Info

*A **blockchain** is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The decentralised database managed by multiple participants is known as Distributed Ledger Technology (DLT).*

{% hint style="info" %}
Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a *hash.*
