what is the blockchain , A blockchain, as it relates to cryptocurrency, is a digital ledger of all transactions. This public record is decentralized, meaning it is not subject to control by any one entity. Instead, it is distributed across a global network of computers. Each “block” in the chain contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin, the first and most well-known cryptocurrency, was created in 2009 as a decentralized way to send money without the need for a third party like a bank or credit card company.

A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere
