Function ethcore_light::cht::start_number [] [src]

pub fn start_number(cht_num: u64) -> u64

Get the starting block of a given CHT. CHT 0 includes block 1...SIZE, CHT 1 includes block SIZE + 1 ... 2*SIZE More generally: CHT N includes block (1 + N*SIZE)...((N+1)*SIZE). This is because the genesis hash is assumed to be known and including it would be redundant.
