That was the answer back then at least. Q: Is it a large cost to keep doing C89? A: The only cost is fo...

# Introduction In spirit of the conversation happening today earlier, I'll give some motivation. In general there is a disconnect between academic researchers and people who work in open-source software. It's a pity because these two groups are interested in bitcoin, they love difficult questions a...

# Introduction I wanted to talk about things that have been leaking out over other conversations because sometimes people get frustrated that their stuff doesn't get merged. This is not a new problem. It's an issue that has been going on for a long time. It can be frustrating. I don't have the answ...

See instead for a full transcript of a similar talk. # Far far future In the far far future, we could get rid of this weird paper notation scheme and do a security proof directly for the specification. Presumably that is much harder than anything else in my slides. But this would rule out a lot o...

Introduction There was an announcement earlier this morning that announced the open-source project implementing Stratum v2 is ready for testing now. Spiral has been contributing to this project for a few years. There's a few other companies funding it as well. It's finally ready for testing. Hist...

# Previous talks # Introduction and motivation Can we turn down the lights? "Going dark" is a nice theme for the talk. I also have dark coffee. Okay. We're going to talk a little bit about [bip324]( This is a BIP that has had a long history. We even have a page about the history. It all s...

# Web of Trust Some of the public key server operators interpreted GDPR to mean that they can't operate public key infrastructure anymore.
