•TACEO Network implements verifiable Threshold OPRF (vOPRF) using a two-secret model for generating nullifiers, where users blind inputs, MPC nodes apply secret shares, and users unblind the output for unlinkable nullifier seeds.[1]
•The network features three layers including a Cryptographic Coordination Layer for job assignment and state management, combining MPC with coSNARKs for verifiable computations on encrypted data shares.[2]
•TACEO provides developer tools like coCircom and coNoir DSL extensions, allowing logic to compile automatically into MPC + coSNARK workflows for privacy-preserving smart contracts across chains.[2]

•vOPRF protocol: User blinds input by hashing to elliptic curve point and multiplying random blinding factor β; MPC nodes collaboratively multiply secret key shares onto blinded point Q' = k · Q; user unblinds with β⁻¹ to get nullifier seed n = H'(x, (β⁻¹ · Q')).[1][6]
•Computations use threshold MPC on encrypted input shares across node committees, with no single node seeing full data; outputs verified via Zero-Knowledge Proofs of correctness.[1][2]
•Integration in World ID includes Discrete Logarithm Equality Proofs (DLog) to verify OPRF nodes used committed public key, preventing node learning of user leafIndex.[6]
•Supports programmable cryptography via DSLs (coCircom, coNoir) that auto-compile user-defined functions into secure MPC + coSNARK circuits.[2]
