Detailed explanation-1: -The Genesis Block was simply the first block of bitcoin (BTC) to be mined. You might see it called Block 0 or Block 1. It’s still there today and will remain there as long as any computer runs the Bitcoin software.
Detailed explanation-2: -The genesis block is the first block of a blockchain. • It is created by the blockchain founder or the first miner on the network. • The genesis block does not reference any previous block, as there are no previous blocks in the chain.
Detailed explanation-3: -A second way to identify a block is by its position in the blockchain, called the block height. The first block ever created is at block height 0 (zero) and is the same block that was previously referenced by the following block hash 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f .
