Kryptik is building the next generation of security, privacy, and anonymity.


Kryptik offers software development and consulting in the following areas. For more information, send inquires to

Mix Networks: Taken together, the Kryptik team has decades of experience building provably anonymous high-latency anonymity networks. Mix networks solve the “metadata problem,” in which nearly all existing systems leak massive amounts of transactional data that can be incredibly personal and valuable to an adversary.

Unlinkable Authentication: Authentication is a fundamental building block of nearly all technological systems. The hallmark of current authentication practice is low security, horrible user experience, and bad privacy practices. Kryptik’s technology allows for a smooth user experience, increased security, and protection of personal information.

Secure Attribute Attestation: As technological systems grow more complicated and involve data that traverses institutional boundaries, it is becoming more important to be able to verify the assertions made by other organizations. Unfortunately, current methods of doing this are often a privacy nightmare, in which far more personal information is shared than is desirable or necessary. Kryptik’s technology allows for the attestation of attributes in a way that maximizes privacy and minimize data sharing and leakage.

Signed Merkle Trees: Will the blockchain hype ever end? Who knows, but at Kryptik, we prefer to not use to B-word. We build technology that uses signed Merkle trees with decentralized certification. You can call it what you want.
