Onosendai is cyberspace built on the Nostr protocol. The “rules” are enforced with physics (proof-of-work).
I thought many people here would find this project very interesting.
There is an inverse relationship between the power one has in cyberspace and the speed at which one can use their power, and this is scaled by your hardware’s capacity for hashing. One can cast powerful events slowly or weak events quickly. This tradeoff is controlled simply by proof-of-work, which is the thermodynamic aspect of cyberspace.
