Genesis Block

Simple Definition of Genesis Block
  • The Genesis Block, also known as Block 0, is the very first block upon which additional blocks in a blockchain are added.
  • It is effectively the ancestor that every other block can trace its lineage back to since every block references the one preceding it.
  • A blockchain starts with a known state. This is a simple matter of an initialized universe in which nothing has happened. It is often referred to as the genesis block.
