Privacy Services on the TACEO Network
The TACEO Network provides privacy services that applications can integrate today, with production deployments across key use cases. Each service is designed for a specific class of privacy-preserving computation.
TACEO:OPRF
Oblivious Pseudorandom Function
Use when you need:
- Generate nullifiers on low-entropy data
- Privacy-preserving uniqueness checks
- Private set membership primitives (e.g. PSI-style protocols)
- Identity-based rate limiting or eligibility checks
Perfect for:
- Anonymous credentials and pseudonymous identities
- Working with low entropy identifiers
- Builder codes and private access / eligibility systems
- Identity-based rate limiting
TACEO:Proof
Private Proof Delegation
Use when you need:
- Generate ZK proofs without exposing witness data to a single party
- Scale proof generation beyond client devices
- Mobile/web app proof generation
- Outsourced Groth16-based proof generation
Perfect for:
- DeFi applications with private transactions
- Identity systems requiring proof of credentials
- Gaming with hidden state verification
- Scalable ZK proofs
TACEO:Match
Distributed Biometric Matching
Use when you need:
- Population-scale uniqueness checks without centralizing templates
- Cross-organization deduplication without sharing biometric databases
- Anonymous identity verification - prove a match without revealing which identity
- Sybil resistance backed by irrevocable biometric uniqueness
Perfect for:
- Proof-of-uniqueness systems and anonymous credential issuance
- Cross-border or cross-org fraud detection and deduplication
- Privacy-preserving KYC and biometric verification
- Any workload where biometric templates cannot be centralized
TACEO:OMap
Private Reads & Writes
Use when you need:
- Private reads and writes on shared state without revealing access patterns
- Confidential key-value storage across multiple parties
- Verifiable state updates with threshold security
- Data structures where no single node should learn contents or access patterns
Perfect for:
- Confidential registries and private allowlists
- Multi-party applications with shared secret state
- Private order books or hidden auction state
- Any workload requiring oblivious data access across organizations

Integration Patterns
Direct API Integration
Integrate TACEO services through service-specific APIs to add privacy-preserving computation directly into your application flow. This is the most common pattern for proof delegation, uniqueness checks, eligibility checks, and related offchain privacy workflows.
Smart Contract Integration
Use TACEO services alongside smart contracts when private computation needs to produce outputs that are verified, committed, or enforced onchain. In this model, confidential execution happens offchain, while contracts handle job sequencing, result verification and other application logic.
