miner(dodgytx)opcheck='imlegit' ->RoadchainSWlite -> otherSWlite-> otherSWlite ->otherSWlite -> otherSWlite

roadchain does no checks and on the data and see's the fraudproof opcode 'itslegit'.. and accepts it and relays it on.. now 4 people have dodgy information.. for no reason.. they cant use it but the 2000 people using the SWlite keep passing it on.. all blindly thinking its valid..

And it's worse, as now it will be essentially free for an attacker to create unbounded numbers of invalid transactions, and the medium-weight SegWit wallets will blindly relay them throughout the network, clogging it up with crap.

shhhhhhh i wanted roadchain to realise it all by himself. Cheesy

next time write 'spoilers'
