I believe I've worked through all those little details over the last year and a half while coding it, and there were a lot of them. The functional details are not covered in the paper, but the sourcecode is coming soon. I sent you the main files. (available by request at the moment, full release soon)

Since 2007. At some point I became convinced there was a way to do this without any trust required at all and couldn't resist to keep thinking about it. Much more of the work was designing than coding. Fortunately, so far all the issues raised have been things I previously considered and planned for.

I don't know anything about any of the bug trackers. If we were to have one, we would have to make a thoroughly researched choice. We're managing pretty well just using the forum. I'm more likely to see bugs posted in the forum, and I think other users are much more likely to help resolve and ask follow up questions here than if they were in a bug tracker. A key step is other users helping resolve the simple stuff that's not really a bug but some misunderstanding or confusion. I keep a list of all unresolved bugs I've seen on the forum. In some cases, I'm still thinking about the best design for the fix. This isn't the kind of software where we can leave so many unresolved bugs that we need a tracker for them.

I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party.

It's very attractive to the libertarian viewpoint if we can explain it properly. I'm better with code than with words though.

Total circulation will be 21,000,000 coins. It'll be distributed to network nodes when they make blocks, with the amount cut in half every 4 years. first 4 years: 10,500,000 coins next 4 years: 5,250,000 coins next 4 years: 2,625,000 coins next 4 years: 1,312,500 coins etc... When that runs out, the system can support transaction fees if needed. It's based on open market competition, and there will probably always be nodes willing to process transactions for free.

Receivers of transactions will normally need to hold transactions for perhaps an hour or more to allow time for this kind of possibility to be resolved. They can still re-spend the coins immediately, but they should wait before taking an action such as shipping goods.

Subscription sites that need some extra proof-of-work for their free trial so it doesn't cannibalize subscriptions could charge bitcoins for the trial.

I'm sure that in 20 years there will either be very large transaction volume or no volume.

I wish rather than deleting the article, they put a length restriction. If something is not famous enough, there could at least be a stub article identifying what it is. I often come across annoying red links of things that Wiki ought to at least have heard of. The article could be as simple as something like: "Bitcoin is a peer-to-peer decentralised /link/electronic currency/link/." The more standard Wiki thing to do is that we should have a paragraph in one of the more general categories that we are an instance of, like Electronic Currency or Electronic Cash. We can probably establish a paragraph there. Again, keep it short. Just identifying what it is.
