Genesis Block

Published on August 30th, 2021

The genesis block is the first block in any blockchain-based protocol. It is the basis on which additional blocks are added to form a chain of blocks, hence the term blockchain. This block is sometimes referred to Block 0. Every block in a blockchain stores a reference to the previous block.

In the case of Genesis Block, there is no previous block for reference. In technical terms, it means that the Genesis Block has it’s “previous hash” value set to 0. This means that no data was processed before the Genesis Block.
