The TACEO stack

Three layers, one stack

Network

The distributed MPC infrastructure underneath.

  • Independent operators
  • Multiparty computation
  • Collaborative SNARKs

Services

Four cryptographic services, exposed as APIs.

  • TACEO:Proof
  • TACEO:OPRF
  • TACEO:OMap
  • TACEO:Match

Solutions

Composition of services on the same network.

  • TACEO Merces
  • TACEO Identity

Four services

Four cryptographic services, callable as APIs.

  • TACEO:Proof

    Live on the TACEO Network

    Private proof delegation

    Outsource coSNARK generation to the TACEO Network. Your application gets a succinct, publicly verifiable proof, no single party ever sees the witness.

  • TACEO:OPRF

    Live in production with 18M+ users

    Oblivious pseudorandom function

    Generate unique, unlinkable identifiers from a user's input, without any party learning the input. The basis of anti-Sybil checks and pseudonymous identity. Construction published in the OPRF paper.

  • TACEO:OMap

    Deployed, onboarding initial applications

    Oblivious map

    Private key-value state. Read and update balances or registries without revealing the access pattern, so every access looks identical from outside.

  • TACEO:Match

    Live in production

    Distributed biometric uniqueness

    Match biometric templates across the network without any single party ever holding one. Pairs with TACEO:OPRF in identity workflows that need biometric verification. Based on the construction published in the iris-biometrics paper, co-authored with the World team.

Composition

Which services power which solution.

Two solutions, composed from these services.

Same network underneath every one.

  • TACEO Merces

    Finance, Agents
    Merces ProtocolTACEO:OMapTACEO:Proof

  • TACEO Identity

    TACEO:OPRFTACEO:MatchTACEO:Proof

TACEO:Proof underpins every solution. CoSNARKs make every service output publicly verifiable onchain.

All of it runs on the TACEO Network

Want to compose your own?

The services compose into anything that needs verifiable computation on data no one should see: dark pools and private swaps, private payroll, pooled confidential data for joint computation across competitors, anti-Sybil checks with custom claims.

Tell us what you're solving. We'll build it with you.
