Assume a wallet that sends double spend of the coin spent for services =
with higher fees to some of its nodes simultaneously.
Merchants will catch and reject most of the attempts, but that will not =

Miner will see a mixed picture and will struggle to act =93honestly=94 =
on a statistical measure.
