TACEO

TACEO is a privacy computing provider focused on zero-knowledge proofs and multi-party computation (MPC). Its core product, the TACEO Network, is a distributed privacy execution layer that enables multiple parties to compute jointly without exposing raw data.

Specific offerings include: TACEO:OPRF, a privacy-preserving identity verification service that generates nullifiers for identity systems without leaking sensitive information; TACEO:OMap, for storing and retrieving private shared state; TACEO:Match, for distributed identity matching; and Merces, an on-chain finance solution providing private payments and compliance checks.

Market pain points: traditional MPC protocols lack the performance needed for production-grade applications, while blockchain's public transparency leaves transaction data exposed. TACEO combines MPC with zero-knowledge proofs to ensure verifiable computation while preventing any single node from accessing complete data, resolving the tension between privacy and compliance.

In the past six months (2026-03-07 to 2026-09-07), TACEO:OPRF entered public beta, operated by 8 independent node operators. Merces launched on testnets including Base, Arc, and Plasma, supporting private ERC-20 transfers. Performance improved significantly: MPC protocols are now four orders of magnitude faster, core OPRF computation takes ~130ms, end-to-end latency including ZK proofs is 1-3 seconds, and the network sustains over 300 transactions per second.
