Not to be confused with ethereum smart contracts where the code can be complex and encoded logic decides what is allowed, not a intermediary human being.
As far as I can tell, this is basically a job board for contractors who want to be paid in Bitcoin. There is a bit of innovation with the "proof of funds" meaning that the contractor can be sure-ish that the money they are meant to be paid actually exists. There are no further guarantees, and disputes are handled by humans.
As it stands we just handle processing of multi-sig contracts
