> Btw, their matching engine is on GitHub and it's a good read! But it hasn't been updated in 2 years... They could definitely open source parts of their current stack if they want to help bitcoin, maybe seeking a "Docker effect". It would be an AWESOME farewell. Bitpay knows how important this is, they are opensourcing a lot of cool stuff... Edit: I've just realised they open sourced a newer matching engine built with scala (I was looking at the old node-based) https://github.com/buttercoin/engine

Nope, although PartTimeLegend is obviously quite disgruntled for some reason I've never entirely been clear on. Nobody was removed from the project on GitHub for over a year after there was last active development. We only took people off of it when some started acting in a disruptive or aggressive manner. Anyone that still wanted to work on that project (buttercoin/buttercoin) was invited to let us know and we would give them access or transfer the repo to them. That repo was the initial open source attempt at a better trade engine in node. It suffered from too-many-cooks syndrome after being started as an announce-first project. There was no clear direction, some people wanted it to be a distributed market, etc. After a couple of months, we thought it would be best to start from scratch with a small team on a focused implementation in S

cala. That's available at http://github.com/buttercoin/engine. The other contentious point was bitcoins that were donated. We posted a couple of times over the course of the year that anyone who had donated should get in touch with us to have their coins returned as the original project looked dead. Nobody contacted us, so we decided the best course of action was to simply return the coins to the address they came from. That irritated a couple of people, but I still think it was the right thing to do, especially as the person who had originally collected donations had left and there was no clear governance setup for their use. The original impetus for the project was to create a more robust and secure way for people to access bitcoin liquidity. Specifically in the US, since that's where people seemed to be having the hardest time getting money in and out of other platforms. In that respect we've succeeding. We're also still committed to open sourcing as much as we can and will continue to expand the buttercoin/engine repo.

Paul started the effort to build an open source trade engine and had buttercoin.com lying around. We joined up with him a couple of days after he announced the idea and started working on it. Cedric and I already had an interview lined up for YC, but we all thought it was a good enough idea to add Paul and change the idea we were applying with. Unfortunately things didn't work out and the original open source effort died off when we decided to start with a fresh implementation. We just recently release the engine we're using (with some minor tweaks) under an MIT license here: https://github.com/buttercoin/engine. We'll be backporting a bit more functionality until we can actually run it in production.
