Block Height
A blockchain is a collection of blocks linked together in an immutable, chronological order.
A blockchain is a collection of blocks linked together in an immutable, chronological order. Beginning at zero with the Genesis block, all blocks are numbered in ascending order. This number is known as a block’s height.
The current block height is simply the number of blocks in the blockchain minus one. Block height can be used as a reference to a point in time within a blockchain. For example, Bitcoin halvings occur at specific block heights (every 210,000 blocks).
Additionally, special Bitcoin transactions can be timelocked until a certain block height.
Block Height is a fundamental concept in Bitcoin's architecture that plays a critical role in how the Bitcoin network processes and validates transactions. Onramp's glossary explains Block Height and other core Bitcoin concepts to give investors a deeper understanding of how Bitcoin works.
