The block height is the number of blocks following the very first one on the blockchain. The very first block is referred to as the genesis block. A genesis block always has a height of zero when nothing follows it. The longer the blockchain is, the higher the quantity of the block height.
The block height of a particular block is defined as the number of blocks preceding it in the blockchain. A blockchain is an encrypted database that records a ledger of transactions sequentially in data structures known as blocks. Blockchains are used as the underlying technology for cryptocurrencies such as Bitcoin.
Block height can either reference the location of a transaction that has been completed in the past’s location in the blockchain, or refer to the present length or size of a blockchain. A block height chart is indicative of how steadily new blocks are being discovered on the blockchain as time passes, amid varying mining difficulty levels.
As of April 2021, the block height for the Bitcoin blockchain exceeds 677,350 blocks, with approximately 144 new blocks added daily.
