A DPI that connects DPIs
SETHU enables reusable, privacy-preserving proofs with uniform validity semantics and auditability. Selective disclosure, governed agentic automation, and purpose-bound data minimisation.SETHU enables reusable, privacy-preserving proofs with uniform validity and auditability.
Court-grade trust for digital proofs
Government-backed, consortium-managed infrastructure. Reusable proofs, credential anchoring, and open standards for wallet interoperability across ecosystems.
Agentic automation with accountability
AI agent registration and negative-event logging on the blockchain. Purpose limitation, minimisation, and policy intercepts for proof requests and tool calls.
Mission
SETHU (Semantic Electronic Trust Harbour Utility) is a trusted digital harbour for interoperable trust services. The SETHU Foundation operates the horizontal infrastructure and court-grade trust layer for the Unified Wallet ecosystem. Government-backed, consortium-managed, public–private blockchain.
Value: Reusable proofs; DID binding (identity hash, virtual ID, fallback); credentials in JWT and AnonCreds; ledger anchoring (Hedera, optional Hyperledger Fabric); AI blockchain services (registration anchoring, negative-event logging on request from TokCredAI); open standards for wallet interoperability. TokCredAI operates AI studio and runtime; SETHU anchors agent registration and logs negative events to the blockchain. We open-source the standards so others can connect to and leverage SETHU.
What we operate
Ledger Network
Hedera Hiero domestic + anchoring to Hedera public; optional Hyperledger Fabric. State writes, mirror read, proofs for global verifiers.
AI blockchain services
Anchor AI agent registration to the blockchain on request; log negative events from the integrating platform's AI runtime to the blockchain on request.
Decentralised IDs
DID issuance and binding to identity hash, virtual ID, or fallback. Credentials in JWT and AnonCreds. Government ID integration and Firebase fallback.
Semantic Layer
Shared schemas, computable policy, programmable journeys. Purpose limitation and data minimisation.
Selective disclosure
Proofs are purpose-bound and time-bound. Derived proofs (e.g. “over 18”, “meets threshold”) without full document sharing. Credentials supported in both JWT (e.g. SD-JWT) and AnonCreds formats. Consent as code; data minimisation; right to erasure supported.
Design principles
Citizen agency & privacy
Minimise disclosure, preserve user control. Purpose-bound, time-bound, consent-driven sharing. Resident-centric data minimisation.
Interoperability & modularity
Open, modular building blocks. Complements identity systems, document wallets, payment rails, and sector connectors. Connects DPIs without replacing them.
Techno-legal regulation
Machine-enforceable guardrails. Purpose limitation, minimisation, accreditation constraints. Policy intercepts proof requests and tool calls.
Monopoly resistance
Multi-operator design, transparent accreditation, portability rules, independent oversight. No single operator or agent platform as gatekeeper.
