This is a talk I did for the Information Security Group<\/a> at Royal Holloway,<\/a> out in Egham. It’s intended as a basic overview of the engineering and computer science problems of blockchain and smart contract promises.<\/p>\n

You’ll see the blockchain and Bitcoin bits at the start are a compressed version of my April talk to the Berenberg blockchain conference.<\/a> I figured I could speed it up for a comp sci audience \u2014 though one questioner asked what git<\/a> was.<\/p>\n

We got video! Starting from the microphone on the camera and the voice recorder on my phone, I’ve compressed and equalised it a bit in Audacity<\/a> to make the sound usable.<\/p>\n

We had twenty minutes of questions! Some of these aren’t clear at all, even after tweaking. But at least you can hear my answers. (Though listening back, in some cases I couldn’t hear the question properly, so answered something that wasn’t quite the question. Sorry about that.)<\/p>\n
