Explore the Bitcoin blockchain block by block
Bitcoin transactions are grouped into blocks. Each accepted block references the previous block, producing the chain of records commonly called the Bitcoin blockchain.
Use the search box above with a block height or block hash to inspect a particular block. The explorer provides the information needed to examine when the block was mined and which transactions were included.
Understanding block height
Block height is the position of a block in Bitcoin's chain. The height increases as new valid blocks are added. A recently mined block sits near the current block height shown in the live network panel.
Block height is often easier to use than a full block hash when discussing a particular point in Bitcoin history.
Blocks, transactions and confirmations
When a transaction is first included in a valid block, it receives one confirmation. Every valid block added after it increases the depth of that transaction in the blockchain.
Exploring a block therefore provides both transaction-level information and broader context about Bitcoin's chain at a specific height.
Frequently Asked Questions
What is Bitcoin block height?
Block height is the numerical position of a block in the Bitcoin blockchain.
Can I search using a block hash?
Yes. A full Bitcoin block hash can be opened in the block explorer.
How are confirmations related to blocks?
A transaction receives its first confirmation when it is included in a block, with additional blocks increasing its confirmation depth.
