Once that’s established, you need to protect the keys and other secrets attached to this identity, such as passwords and cryptographic keys. In this blog post I will write about my own personal approach to this with some recommendations. … Continue reading Securing your digital home – part 3: keys and other secrets
Fungible currency is, or must be, a cornerstone of a democratic and free society. In this blog I will explore what a fungible currency is and why Bitcoin and Ether currently are lacking in this respect. What does “fungible” mean? Goods or items in a collection are “fungible” if all of the items have the … Continue reading Fungibility – why Bitcoin or Ether aren’t the most democratic currencies yet
If you thought blockchain and cryptocurrencies are the most avant-garde or anarchist technologies of today, I will say you’re wrong. There’s an even bigger and bolder idea out there that I’ve been following for a while — it’s called Urbit. I must admit that I didn’t fully understand Urbit, until recently when I started playing … Continue reading What is Urbit?

All passwords were … Continue reading Padlock – my new password manager
Having a basic understanding of encryption and digital signatures has become important as history has repeatedly taught us that we can’t trust everyone on the Internet (e.g. Internet service providers, email services etc.). This blog post will try to explain in a non-technical way how encryption and digital signatures work and why something called “private … Continue reading Non-technical explanation of encryption and digital signatures
I have for the longest of times been a Firefox user. I love what Mozilla, the foundation behind Firefox, has done to bring more freedom, transparency, privacy and security to the web.
