This is the blog of 20[] (pronounced ‘20 squares’), a company focused on employing compositional techniques in game theory and mechanism design to model and simulate complex systems, with particular attention to crypto.

As research moves fast in crypto, this blog will serve as a repository for ideas that we are happy to share, but that are not yet sedimented or mature enough to be turned into full-flagged academic papers.


We are strong advocates of cooperation and we want to keep this blog as open and plural as possible. We plan to have guest posts by friends and colleagues working in the broader crypto ecosystem and beyond. Hopefully, they will start appearing soon. Feel free to ping us if you think you have something interesting to say that you want to see published here!
