This is the first block, and in it the creators of Ethereum were at liberty to say “To start, the following accounts all have X units of my cryptocurrency.” This section describes how to pre-allocate ether in the genesis block. In previous tutorials, we have learned how to create a private Ethereum network, mine new blocks, and collect mining rewards. By default, the total Ether value of the network starts with no pre-allocation Ethers.
