Today we’ll talk about cognitive biases that influence our perception of everything. As our unconsciousness can affect our thought and judgment, it will be good to follow some core principles.

You can hardly find a person today who haven’t ever heard of blockchain with its promise of security, immutability and transparency. Decentralized, distributed, tokenised networks are now top of mind for nearly every business leader. We can see businesses and even entire governments investing in blockchain initiatives. While more and more decentralised apps are entering the market, I decided to take a closer look at what it takes to create a UX design for blockchain and how to do it right.
