I'm expecting shenanigans with tomorrow's dividend payments due to the new "malleability bots". Since the dividend payments are normally sent using a chain of unconfirmed transactions, any transaction that has a mutated version confirmed will invalidate all the transactions further down the chain.

He (or anyone else) could not completely protect against this other than sending one group, then wait for confirms, then send the next group, etc, but maybe it is possible to improve the odds? What if the final transaction in the chain had a higher than usual fee? Wouldn't that encourage a rational miner to mine the whole chain instead of piecemeal?

Otherwise, he (or anyone else) would have to watch the confirms and, if it gets off track, reissue all the dependent transactions. That sounds like a pain in the butt to me. Of course, I have no idea what his internal system is for generating and broadcasting the payments. It is possible that he has already considered the mischievousness of others.

Any thoughts?

Submit the entire chain by directly connecting to the largest mining pools. The malleated transactions will be seen as double spends and not accepted into mempool.
