All you never wanted to know about the Banking System and why it keeps crashing Economics.

Clairvoyance 🔮
Jacky
Based on the world´s first, and as far as we know still the only accurate double entry bookkeeping based simulation of the banking system, we will talk through how fractional reserve banking really works from a network perspective, and how it has influenced both economic activity and economic theory in many unappreciated ways. If you want to be able to predict what the central banks will do next, and how to make sensible financial decisions despite this, this is the talk to you. Inflation is back, and it´s still the same. We´ll also talk about ways to contribute to the development of economic models and simulations that are based on real economies, and not on a 30 year practice of fitting a very short mathematical ruler, to a very long curve.
It all started innocently enough, with an attempt to build a simple banking simulation in python of the standard Economics 101 textbook description of the banking system. This failed to work as soon as loan repayments were put in. The next version was a little more complicated, agent based, and used double entry book keeping, and the version after that added some simple economic features like widget producers and households (which actually makes it as sophisticated as "sophisticated economic models" (it´s still nowhere complete though), and has been used to enlighten/confuse several classes of computer science students at Reykjavik University in Iceland. Along the way we learnt how money gets created and destroyed, how several different kinds of bank regulation actually worked, identified several positive feedback loops in the financial system, how international money transfers don´t actually transfer money, and why it was probably inevitable cryptocurrency would re-invent fractional reserve banking right after they reinvented its book keeping.

This is a submission for a keynote talk at MCH2022. The Internet is both a familiar, comfortable place as well as a bottomless rabbit hole you can lose yourself in. The Internet has always been like this from its inception, the difference now is the scale and consequences are almost immeasurable - and it tests the limits of human imagination. When you look into the mirror of the Internet what you see reflected back depends on what you are looking for. It has become largely a reflection of ...

Have you ever forgotten a passphrase or lost a hardware token? Lost access to enough Bitcoin to buy a pizza or two? Encryption is fundamental to securing our liberties, but key and password management remain difficult even for professionals, let alone the general public. This talk presents Passcrow, an Open Source project attempting to address one of crypto's largest usability issues: password and key recovery in a decentralized environment.

Thanks to DNSSEC and DANE, it is possible to automatically verify user@domain.name identities by checking with domain.name servers. The real problem however, is integration with existing protocols, instead of inventing something completely new and perhaps web-only. The purpose of our work on Realm Crossover mechanisms has been to design generic solutions that extend many different application protocols, without changing their protocol specs.
