so we have:
TX1 + TX2, TX3 + TX4, TX5 + TX5
Then the next round:
TX1TX2 + TX3TX4, TX5TX5 + TX5TX5
Then,
TX1TX2TX3TX4 + TX5TX5TX5TX5
and finally the root is,
TX1TX2TX3TX4TX5TX5TX5TX5
Is this how to do it?
Thanks,
Ryan
Small correction: when there are an odd number of elements in a level, the last one is hashed after appending it to itself. So usually hash6 of one level is H(hash12+hash13) of the level below, but it can be H(hash12+hash12) if hash12 is the last one.
