TACEO
TACEO GmbH
TACEO builds a privacy layer for public blockchains based on multi-party computation (MPC) and coSNARKs: it combines Multiparty Computation and zero-knowledge proofs to create "Private Shared State" — encrypted shared data you can compute on, update and prove correct without ever exposing it. It offers services such as OPRF (private identifiers), OMap (encrypted lookup), proof generation and private set intersection, aimed at confidential payments, identity verification and AI agents. Its MPC network has supported biometric verification for over 14 million World ID (formerly Worldcoin) users.

Strengths
- Advanced, verifiable cryptography (MPC + coSNARKs/zero-knowledge), non-custodial by design
- Real large-scale adoption: MPC network behind World ID biometric verification (14M+ users)
- Team of cryptography researchers (Graz University of Technology) backed by well-known funds (a16z CSX, Archetype)
- Self-custody: funds stay in your wallet — the platform cannot touch them.
Weaknesses
- B2B/developer infrastructure: not a product usable by an end consumer
- Early-stage (2025 seed): maturity and adoption still building outside flagship use cases
- No financial licence (it is a technology layer, not a regulated intermediary)
- No notable sovereignty drawback documented.
Verdict
Score 3.6/5, solid profile. In its favour: advanced, verifiable cryptography (MPC + coSNARKs/zero-knowledge), non-custodial by design. The trade-off to weigh: b2B/developer infrastructure: not a product usable by an end consumer.
On the Sovereignty lens the score is 5.0/5 (outstanding): the strength is fund control (5.0/5).
Promp's editorial rating based on real fees and net annual cost. Promp reviews third-party products independently.
"Sovereignty" rating: score computed on privacy/anonymity (30%), fund control (20%), censorship resistance (20%), trustless/auditability (20%) and costs (10%). Same data, different weights.
FAQ
Does TACEO custody my funds or data?
No. It is a cryptographic compute layer (MPC + zero-knowledge): it processes encrypted data without exposing it and does not hold user funds. Its "Private Shared State" design is non-custodial.
Can an individual use it?
Not directly: TACEO is infrastructure for developers, protocols and companies integrating privacy into their applications. An individual only encounters it indirectly, e.g. as a user of a service like World ID.
