Cryptocurrencies were supposed to destroy the traditional monetary system. Ten years on, where are we?
Bitcoin has been wildly successful, but as a financial game–not as a medium of exchange.


Your data is not property. It’s a piece of who you are.

The Facebooks and Googles of the world are getting rich off your data. Market researchers at PwC estimate that in 2018, companies that collect personal data to use for targeted advertising brought in $178 billion in revenue. Data brokers last year earned a further $21 billion. And these numbers are only trending up. By 2025, PwC expects the global data economy to be worth more than $400 billion.

So it’s about time we get in on the action, right?



hand-holding guide to the Simple MultiSig Wallet, with plenty of screenshots

In this article I’m going to introduce a typical use-case for a MultiSig wallet, and then walk you through how to execute multisig transactions using Christian Lundkvist’s Simple MultiSig Wallet. I’ll be using the user interface for the Simple MultiSig Wallet that I wrote — it’s completely free to use and available on IPFS:

The walk through will have lots of screenshots. I know that format can be tedious for some people — but if you’re setting up a MutiSig Wallet with large sums of ETH it can be re-assuring to actually see how the screens will look.



Does game theory apply to real life? It’s easy to fall into one of two errors:

  1. Thinking that human interactions can be precisely modeled by a 2×2 payout matrix, and being shocked by the vagaries of human psychology.
  2. Thinking that since humans aren’t rational game theory doesn’t apply to them, and being shocked when they follow incentives in predictable patterns after all.

Of course, human behavior is a combination of both elements: the mathematical structure of payoffs, incentives, and equilibria, the idiosyncrasies of culture, mood, and personality. Understanding both sides can be quite a superpower. I know people who made millions and bankrupted competitors by tweaking some small features of a public auction. This stuff is hard, but it works.

I took every available class on the math of game theory as an undergrad. Since then, I’ve been catching up on the squishy human part of the equation. There’s plenty of great research in this area, but the best way to learn about people is to observe them in their habitat. So when my friend Spencer told me that he’s organizing a live game theory party, I jumped at the opportunity.

I will break with tradition by not repeating the descriptions of common games that you’ve heard 100 times before, nor by deriving the rational strategies and equilibria. If you need to catch up on the math you can follow the links to Wikipedia etc. Weiterlesen
