Block height, as it pertains to cryptocurrency, refers to the current number block in a blockchain. The genesis block, which is the very first block in any blockchain, has a block height equal to zero. Therefore, the block height is always a positive integer greater than zero.
A block is simply a collection of individual transactions such as Alice sends 1 bitcoin to Bob. When transactions are bundled together, the bundle then becomes referred to as a block.
As well as containing a batch of transactions, each block will contain a cryptographic hash and a timestamp in order to ensure the integrity of the block, as well as the entire blockchain.
