Block Height

Block height is a measure of the length of a blockchain and refers to the number of blocks that have been added to the blockchain. Each new block added to the chain increases the block height by one.

Block height is an important metric for blockchain users and developers, as it provides a way to track the progress of the blockchain and verify that transactions have been properly recorded. When a user makes a transaction on the blockchain, they can check the block height to ensure that the transaction has been added to the blockchain and is considered valid.

Block height can also be used to measure the security of a blockchain. As the block height increases, the difficulty of altering past transactions also increases, making the blockchain more secure and resistant to attacks.

In some cases, block height can also be used to determine the fork status of a blockchain. When two or more versions of the blockchain exist, each with a different set of blocks, the version with the highest block height is generally considered the valid chain.

Block height can vary between different blockchain networks, depending on the block size, block time, and other factors.
