What Is a Block in Bitcoin?

A block is a record of some or all of the most recent Bitcoin transactions that have not yet been recorded in any prior blocks. Blocks are “stacked” on top of each other in the Bitcoin blockchain.

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.

Blocks are organized into a linear sequence over time (also known as the block chain). 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.

The first transaction in a block is called a coinbase transaction and is used to collect newly minted bitcoins and any transaction fees paid by the sender. A single coinbase transaction can create multiple new bitcoins, all of which are owned by the miner who created the block.
