Are you quite certain that the order here is correct?

I don't think the ordering matters, it seems like the root hash result is the same either way.

Ok, I don't think there will be any difference unless there are either suicides or empty touch-deletes involved. In those cases, true signals to use state-clearing rules, meaning that this will be incorrect for e..g frontier rules. So if you provide a genesis where frontier is disabled, this will not be correct. A more correct approach would be to use

  statedb.Commit(chainConfig.IsEIP158(block.Number())

Actually, it's already hardcoded to true as is, so I'm fine with this

statedb.IntermediateRoot(true)
fmt.Println(string(statedb.Dump()))
}
