many pools accept P2SH addresses as users , but don't give shares for work, because can verify and recognize only P2PKH and give shares .
Kano isn't such pool. CKpool code accept P2SH. Am I right?
Sorry, I've no idea what you mean by "but don't give shares for work"
I mean that some pools use p2pool similar code and when username is P2SH address starting with 3 , work made by that miner don't go in db for payments , and all work shares go to pools owners
In the payout for our first block (325306), someone had a 3* payout address.
