T3N is decentralized by design, offering resilience and censorship resistance while maintaining data privacy and strict regulatory compliance from day one. It achieves this through a multi-region topology that keeps regulated data inside its required jurisdiction, all while operating as a single, interoperable network. T3N is accessible through:

Connections
-----------
  Cluster 1  <-->  Cluster 2   (cross-region threshold key sharing)
  Cluster 1  <-->  Regional Storages    (in-region storage)
  Cluster 2  <-->  Regional Storages    (remote access to Region 1 storages)

​
Trusted Execution Environment (TEE) Clusters

TEE clusters are the computational layer of T3N. Each TEE cluster is geographically distributed and consists of multiple TEE nodes. Each node holds a key share of the overall threshold key for the whole network. All confidential data processing is performed inside each node’s Trusted Execution Environment (TEE) - secure computational enclaves within processors that deliver enhanced security beyond conventional operating systems.

​
Regional Storage

TEE nodes and storage are co-located within regions to meet data residency requirements. T3N is storage technology agonistic. Any storage solution can be integrated with T3N to serve different requirements. Currently,it supports two storage options: Content-Addressable Storage (CAS) and Regulatory Vault.

​
Content-Addressable Storage (CAS)

CAS is a storage system that stores data based on its content rather than its location. It’s a pluggable external storage backend for large data values.

​
Regulatory Vault

The Regulatory Vault is secure, centralized storage managed by Terminal 3 for regulated partners. It securely holds sensitive KYC data (passports, liveness videos, etc.) specifically for compliance and enforcement purposes. By providing immutable auditability, it acts as a verifiable system of record to prove to regulators that all KYC requirements were met.
