The Only Trust-Native Technology for AI-Based Application Development

A purpose-built stack where authorization is language primitives, and security and auditablity are ensured by design.

The NOUMENA stack

Four layers, one coherent model. Each layer builds on the guarantees of the layer below. Choose the products you need and use them together or independently.

Layer 4

NOUMENA Cloud

Managed Infrastructure

Auth, Observability, Scaling

Layer 3

NOUMENA Adapters

Integrating external technologies

Blockchain Adapter, HTTP Connector, Mail Connector

Layer 2

NPL Runtime

Execution Engine

Transactions, Persistence, Audit, APIs

Layer 1

NPL Language

Foundation

Protocols, Parties, Permissions, State Machines

Why NOUMENA

Security, compliance, and correctness. Structural guarantees by design.

Traditional approachNOUMENA approach
Authorization scattered across servicesCompiler-enforced permissions: if it compiles, the permission model is correct
Manual state management, partial updatesTransactional execution: atomic operations, no inconsistent states
Audit trails bolted on after the factAutomatic audit logging: every action captured to a tamper-proof trail
Security reviews as archeological expeditionsSecurity as grammar: parties and permissions are language primitives
APIs drift from business logicGenerated APIs: REST endpoints, OpenAPI specs, and TypeScript clients from your protocols
Product

NPL and Runtime

Deterministic language plus secure execution engine. The foundation layer.

NPL (Noumena Protocol Language) is a deterministic, domain-specific language where parties, permissions, and protocols are first-class constructs. The Runtime executes NPL code with transactional guarantees.

Authorization is not a library. It is grammar. Define who can do what directly in your protocol definitions. The compiler verifies your permission model; the runtime enforces it.

Parties and permissions

Authorization is grammar, not library code. Define who can do what directly in your protocol definitions.

Finite state machines

Model workflows as explicit states and transitions. No hidden states, no impossible transitions.

Transactional execution

Atomic state changes. Either everything succeeds or nothing changes.

Automatic persistence

Protocol instances stored with full version history. No ORM, no migrations required.

@api to REST endpoints

Annotate protocols and get production-ready APIs with OpenAPI specs and TypeScript clients.

Complete audit trail

Every permission check, every state change, logged automatically.

Code example

@api
protocol[issuer, holder] SimpleToken(var balance: Number) {

    permission[issuer] mint(amount: Number) {
        balance = balance + amount
    }

    permission[holder] transfer(to: Party, amount: Number)
        requires balance >= amount {
        balance = balance - amount
    }

    permission[issuer] burn(amount: Number)
        requires balance >= amount {
        balance = balance - amount
    }
}

What you get: Compile-time verification that only issuer can mint/burn. Runtime enforcement of balance checks. Automatic audit trail. Generated REST API with proper authorization.

Best for: Complex multi-party workflows, high-stakes transactions, regulated environments requiring fine-grained access control and complete audit trails.

Product

NOUMENA Adapters

Connect NPL to external systems. HTTP APIs, email, and blockchain networks.

Adapters extend NPL protocols beyond their own runtime. Call external REST APIs, send transactional emails, or integrate with blockchain networks and payment rails. Each adapter is fully integrated with NPL's permission model and audit trail.

HTTP Connector

Connect NPL protocols to any REST API. Trigger webhooks, fetch data, and orchestrate third-party services directly from your protocol logic.

  • Outbound REST calls from NPL actions
  • Configurable authentication (API keys, OAuth, mTLS)
  • Automatic retry and circuit-breaker patterns
  • Request/response mapping to NPL types

Mail Connector

Send transactional and notification emails from NPL protocols via any SMTP server. Template-driven, audit-logged, and fully integrated with the permission model.

  • SMTP integration with TLS support
  • Template-based email composition
  • Attachment support from protocol data
  • Delivery tracking in audit trail

NOUMENA Pulse

Blockchain Adapter

Digital asset middleware connecting NPL applications to blockchain networks, payment systems, and financial infrastructure. One interface for multiple chains.

  • Multichain support (EVM, Stellar, Polkadot, Cardano, Near)
  • Wallet abstraction and key management
  • Lifecycle services: issuance, redemption, transfer, settlement
  • KYC/compliance hooks and regulatory alignment
