BTC: 19, 500 appx
Ripple XRP: .71
Etherium: $701.61

This show starts with a survey of the blockchain landscape, how coins are mined, and how the US government views it.

Scott discusses the promise of blockchain as a disruptive technology.

Jeff says distributed databases have certain unsolveable problems with the durability / latency tradeoff.

How eventual consistency ends up rendering sequences of transactions that are impossible.

What is the source of truth in information. A look at relativity in physics and why computers can be similar.

How does Moore’s law affect blockchain?

What’s the solution to the central math problem keeping cryptocurrency?

What’s the Discrete Log Problem, and what does it mean for it to fail?

How blockhain may be more useful for bespoke or closed-system applications.

How to reappropriate mining gear profitably.

How many of the world’s decisions need to be replaced by machine learning algorythms given today’s technology?

Ian’s rant on drivers and why drivers need to be replaced by algorythms.

How and why to locate a data center.
