From what I have understood, the number property from the genesis file represents the block number (to match block structure). So, logically, it should be 0x0 because the genesis file is the first block (block 0).

What would happen if I put something else ? Would the initialization of the chain fail ? Would the chain start at block X ?

  • Which number are you talking about? Is this for a private network or main chain?
