It’s more about devs than companies. Each element has its own enthusiasts, and a strong open source culture. You know the bitcoin ones well, I’m sure. The others are similar in spirit, and passion, and usefulness.
The way open source is funded is so interesting. Grants etc. But I personally love the idea of funding companies with break-out sovereignty tech. Maybe that's not possible within the guardrails of incoroporation? Ie the state captures the essence of these tech at limited liability. Do you see any companies actually breaking out into growth phase? It will be all about how you analyse them I think
