Block Height
blockchain
The position of a block in a blockchain, counted from the genesis block at height zero.
1
definition
Block height is the number assigned to a block based on how many blocks came before it. The genesis block has height 0, the next block has height 1, and every new accepted block increases the chain tip height by one.
2
usage
Block heights are used to reference upgrades, halvings, snapshots, and historical events because they are unambiguous within a chain. During synchronization issues or forks, different nodes may temporarily report different tip heights.
