Block Height

Definition ∞ Block height refers to a block’s position within a blockchain’s sequential order. It represents the total number of blocks preceding a specific block in a distributed ledger, starting from the genesis block. This numerical identifier serves as a unique timestamp and an ordered reference point for all transactions contained within that block. Higher block heights signify a greater accumulation of verified transaction data and network activity, indicating the chain’s progression.
Context ∞ News often references block height to indicate specific network upgrades or forks, which are frequently activated at predetermined block numbers. Monitoring block height provides a real-time indicator of a blockchain’s operational progress and confirms the finality of transactions up to that point. Discussions around network congestion or processing speeds often cite the rate at which block height increases, offering insight into network health.
