gmaxwell was talking about colored coins[1] in IRC recently. They are potentially interesting in the context of distributed bonds[2], which I am currently pursuing with pybond[3]. Here is the problem I am trying to solve, does the crowd have an answer? 1. Alice transfers a 1-satoshi colored coin to Bob. 2. Bob transfers 100 BTC to Alice. May be restricted to 1 txout, if that eases implementation details. 3. Steps #1 and #2 happen as an atomic unit, all-or-none. 4. Alice and Bob must both approve this atomic transfer of coins, with appropriate signatures. Is this possible within the current bitcoin system? As far as I can see, the answer is "no" but maybe I'm missing something. My best guess to the answer is "possible, but requires a new SIGHASH_* type"?
