Description: Block height in a blockchain refers to the total number of blocks that have been added to the chain since its inception. Each block contains a set of transactions and is linked to the previous block, thus forming a continuous sequence. Block height is a crucial indicator for understanding the state of the chain, as it reflects how many transactions have been processed and confirmed. As new blocks are added, the block height increases, which can also influence the security and integrity of the network. For example, in various blockchain networks, block height is used to determine mining difficulty and the estimated time for confirming new transactions. Additionally, block height can be a factor in implementing updates or forks in the network, as certain changes may be scheduled to activate at a specific block. In summary, block height is a fundamental concept in blockchain technology, as it provides information about network activity and its evolution over time.
