About Us
QEDIT is a team of cryptographers, protocol engineers, and formal-methods specialists who design, audit, and prove the cryptography behind systems that move real value
Founded in 2016, QEDIT is an applied cryptography firm. We design cryptographic protocols, audit the systems that implement them, and prove them correct with machine-checked proofs.
Our team combines world leading cryptographers, protocol engineers, and formal-methods specialists, working across zero-knowledge proofs, privacy-preserving protocol design, and formal verification.
We co-founded ZKProof, the open industry-and-academia initiative standardizing zero-knowledge proofs, and we continue to help shape how the field is specified and verified. The work we take on is the kind where correctness cannot fail - and where a proof, not a test suite, is the standard of evidence.
