Private net allows the creation of an entirely new blockchain. This is different from testnet or mainnet in the sense that it uses its on-genesis block and network ID. In order to create private net, three components are needed: Network ID. The Genesis file. Data directory to store blockchain data. Even

to have the same genesis file and network ID, they may connect to your private net. The chance of having the same network ID and genesis block is very low, but, nevertheless, disabling node discovery is good practice, and is recommended.

This is the first block in the network and does not point to any previous block. The Ethereum protocol performs checking in order to ensure
