Achi is a new and the first truly decentralized cryptocurrency based on a Proof of Space (PoSp) and Proof of Time (PoT) consensus algorithm with independent Timelords and unique K=32 plots.

Achi features zero prefarming and dynamically sized difficulty and block sizes. It provides transactional functionality from get go, it incentivises independent timelords and farmers to secure the blockchain cooperatively. It is not compatible on farming level with existing corporate blockchains. It is coded as how Proof of Space and Proof of Work blockchain should have been done in the first place.

All the free spirted people of the world are invited to join and to move forward together as farmers, timelords, users, and developers. Together we have this opportunity to innovate. Together we can create and maintain the first truly decentralised and independent currency of the word!

My grand goal for this project is simply The Good of The Mankind.
