Distributed Nullifiers

Distributed Nullifiers is enabled by TACEO:OPRF. TACEO's production service for computing threshold Oblivious Pseudo-Random Functions (OPRFs).

A nullifier derived from a single secret is only as safe as that secret. TACEO's distributed approach requires a threshold of independent MPC nodes to cooperate before any nullifier can be evaluated, so no single party - including TACEO - can link or deanonymize your users even if user secrets are compromised partially compromised. Beyond nullifiers, TACEO:OPRF can serve any use case requiring distributed, verifiable pseudorandomness.

In production for World and zkPassport.
