I’m kind of surprised there’s no open source exchange with much traction yet. I think Buttercoin was the first attempt but they pivoted then failed. It looks like there’s a few others but only a few small exchanges use them: https://www.reddit.com/r/Bitcoin/comments/37ku14/open_source_exchanges_blinktrade_vs_wlox_vs/ https://www.reddit.com/r/Bitcoin/comments/37ku14/open_source... Something that provides the core features of an exchange with focus on excellent security and proof-of-solvency built-in would give small exchanges (like BitGrail) a competitive advantage. Additional benefits would include having a standard API others could more easily write tools for, and opportunity to experiment with things like instant cross-exchange transfers using payment channel / Lightning Network. That said, it’s a pretty big undertaking. To do it well it would probably take a funded (or already successful) exchange or other company with related business model willing to do it.
