I can't remember...

Can anyone help what is the cryptocurrency that has the option to revoke (or something like that) a transaction if the second party in the transaction did not fulfill his trade?

I read that type of cryptocurrecy before but I can't remember what was that coin....
I believe I read that in this forum website.

Thanks in advance for any replies.

To me it sounds like you're looking for the term multisig escrow / wallet!
