https://bitcointalk.org/index.php?topic=297147.0Would you consider implementing the hop protocol. It is a radical modification.
Similar goals to bitshares and mastercoin, but hop will actually work. Bitshares and mastercoin are failures in progress.
I think you need hop to oust bitcoin from the leaderboard. Lock-in is significant now. Marginally superior tech will lose to the incumbent, bitcoin.
Offer anything less than hop and you will be competing for second place. Why not aim higher?
