As an example Attacker sends me 10,000 Bitcoin in trade for $1 billion USD, however secretly begins mining a sequence the place the ten,000 Bitcoin was despatched to himself.
After I launch the $1 billion USD, he broadcasts his heavier chain, undoing the transaction and conserving my $1 billion.
In response, I broadcast a child-pays-for-parent transaction from “my” UTXO on the shorter chain: the one which Attacker undid. I connect an especially giant payment, for instance, 100 Bitcoin.
My hope is that sincere miners would see that this youngster transaction is invalid on the longest chain, however it could be legitimate in the event that they mine on the shorter chain. Then, this may induce extra hash energy to come back on-line to reap the extraordinarily worthwhile charges, which might overpower and undo Attacker’s re-org.
Does the sport concept on this make sense? How excessive would my payment must be to ensure that sincere miners to find out that the EV of attempting to mine on the shorter chain is price it?
