What does "block height" refer to in blockchain?

Block height refers to the number of blocks in a blockchain from the genesis block (the first block in the chain) to a specific block. It is used to track the chronological order of blocks in the blockchain and is an important metric for determining the current state of the blockchain network.

In blockchain, the block height refers to the position of a specific block within the blockchain's linear sequence of blocks. Each block added to the blockchain has a unique block height, which represents its position in the chain, with the initial block being designated as block height 0 or block 1 (depending on the blockchain). The block height serves as a chronological indicator, providing the order in which blocks were added to the blockchain and facilitating the identification of specific blocks within the chain's history.
