Genesis Block
The genesis block is the first block in a new blockchain, and it is created when the blockchain is first launched. It typically contains a small amount of data, such as the time the block was mined and the initial block reward for miners.
The genesis block is hardcoded into the software of the cryptocurrency and is not mined like other blocks, but rather created as a part of the software. The data in the genesis block is also important for the network’s consensus mechanism and security.
