TACEO develops cryptographic infrastructure for private computation on blockchain networks. The company builds a compute network for Private Shared State (PSS) that enables verifiable collaboration directly on encrypted data using Multi-Party Computation (MPC) and collaborative SNARKs (coSNARKs). The TACEO Stack consists of three main components: the TACEO Network, which provides MPC and coSNARKs infrastructure for private shared state; TACEO Services, which offers foundational primitives including proof generation, Oblivious Pseudorandom Functions (OPRF), and Oblivious Map (OMap) services; and TACEO Tooling, which provides developer tools to run Circom and Noir circuits in MPC environments. The company's core services include TACEO:OPRF for generating persistent, unlinkable user identifiers without compromising secret keys; TACEO:OMap for verifiable storage and retrieval of confidential shared state; and TACEO:Proof for outsourcing complex zero-knowledge proof generation to the network. TACEO targets blockchain applications across multiple sectors including decentralized finance (DeFi) for confidential trading and dark pools, collaborative AI for privacy-preserving machine learning, data ownership solutions for encrypted dataset computations, and gaming for hidden moves with verifiable outcomes. The company collaborates with Aztec to build private shared state capabilities on Ethereum. The team includes cryptography researchers and engineers from Graz University of Technology, with expertise in threshold cryptography, zero-knowledge protocols, and post-quantum cryptography.
