The zase Foundation is a non-profit dedicated to privacy-preserving and verifiable computation: cryptographic research and open-source tools that keep what you compute confidential, while letting the result be checked by anyone who needs to trust it.
Two problems sit at the heart of the Foundation's work. Privacy: metadata — who talks to whom, when, and from where — leaks more than message contents ever did, and a global passive observer reconstructs lives from it. Verifiability: computation is expensive, but checking a result can be cheap — so a result should be able to travel with a succinct proof that it is correct. We study the cryptography for both and release it openly.
Authenticated, key-committing encryption; sender anonymity via ring signatures; threshold authorization; continuous-time mix-style cover traffic. The building blocks of metadata-resistant systems.
"Computing is expensive; verifying can be cheap." We research certificates that let an untrusted party prove a result is correct without redoing the work.
Apache-2.0 source, public specifications, a pinned toolchain and reproducible builds, and a supply-chain-audited dependency tree.
A non-profit steward, not a company. The work answers to its users and to the research, never to a cap table or an exit.
We state plainly what is proven, what is assumed, and what still needs external audit. Hand-rolled cryptography is not relied upon until reviewed.
The smallest system that solves the problem has the smallest attack surface. We delete more than we add.
