Node Operators

The network is operated by independent node operators running MPC infrastructure. Node operators are currently permissioned, high-reputation parties to ensure reliability and security for production workloads.

For each service instance, computation is assigned to a committee of nodes rather than a single operator.

This committee model is what enforces distributed trust:

  • no single operator can unilaterally access full private inputs
  • no single operator can produce a valid result alone
  • threshold participation is required for successful execution

As the network expands, participation is expected to broaden while preserving threshold-based security guarantees.

Security Model​

The TACEO Network is built on threshold MPC protocols designed to protect data during computation.

At a high level, the security model assumes:

  • fewer than the configured threshold of nodes collude in a given committee
  • node operators run approved protocol implementations correctly
  • service and governance controls are operated according to network policy

Under these assumptions, private inputs remain confidential and outputs are produced through protocol-level distributed execution.

In practical terms, security combines cryptographic guarantees with operational controls, including committee diversity, controlled service deployment, and active infrastructure monitoring.
