Hypercerts Foundation
Head of Engineering

To solve the challenges we face this century, we need scalable and sustainable financing models for public goods that reward contributors for the positive impact they create.

Hypercerts are a new protocol for funding and rewarding positive impact. Every hypercert is a public claim on a discrete piece of work and impact resulting from that work. Projects can create hypercerts and distribute them to contributors. Funders can own hypercert fractions — and the rights that come with them. Impact evaluators can create value for projects and funders by assessing the quality of hypercerts and offering ratings.

Hypercerts create interoperability by serving as a single, open, shared, decentralized database for impact claims and funding mechanisms. This allows funders and projects to create a scalable, interoperable and transparent funding environment for innovative public goods.

Did you ever feel, as though you had something inside you that was only waiting for you to give it a chance to come out? Some sort of extra power that you aren't using - you know, like all the water that goes down the falls instead of through the turbines?

Scientist & Writer

They cannot be worthy of the respect and admiration of the people unless they add to the virtue of obedience some other virtues—the virtues of manliness, of truth, of courage, of willingness to risk positions, of the willingness to risk criticism, of the willingness to risk the misunderstanding that so often comes when people do the heroic thing.

Real estate cannot be lost or stolen, nor can it be carried away. Purchased with common sense, paid for in full, and managed with reasonable care, it is about the safest investment in the world.




Diamond cannot be polished without friction. Gold cannot be purified without fire. Good people go through trials, but don’t suffer. With that experience their life becomes better, not bitter.





We must not cease from exploration and the end of all our exploring will be to arrive where we began and to know the place for the first time.
