Orchestration Protocols Across Distributed TEEs

Coordinating Secure, Multi-Node Execution at Scale for Global Governance Workloads

4.10.1 Why Orchestration is Critical in a Distributed TEE Network

NSF is designed to operate across:

• Geographically distributed enclaves

• Multi-tenant governance domains

• Time-sensitive, simulation-triggered clauses

• Jurisdiction-scoped infrastructure

To support this, the system must provide secure, verifiable, and efficient orchestration of:

• Clause dispatch

• Input binding

• Execution scheduling

• Result aggregation

• CAC rollup formation

• Redundancy and failover

• Governance-bound load distribution

This requires orchestration protocols that balance:

Objective	Requirement
Security	Trusted enclave attestation, scoped execution, replay protection
Scalability	Load-balanced task distribution across global compute nodes
Finality	Deterministic result agreement, with quorum-based output validation
Auditability	Traceable execution lineage across nodes and time
Governance compliance	Domain- and jurisdiction-specific policy enforcement

4.10.2 NSF Orchestration Components

Component	Function
Scheduler	Accepts clause jobs, validates scope, assigns to TEE nodes
Runtime Coordinator	Initiates secure execution across TEEs with enclave hash validation
Input Resolver	Prepares bound input bundles from the Data and Credential Layers
Proof Aggregator	Collects CACs, verifies enclave attestations, assembles rollups
Governance Filter	Ensures execution only occurs under valid DAO/treaty parameters
Fallback Router	Handles node failure, retries, and rerouting of time-sensitive clauses

All components are modular, crypto-enforced, and DAO-governed.

4.10.3 Clause Dispatch Workflow

1. Trigger Event (sensor, simulation, or DAO proposal) activates a clause

2. Scheduler checks:

   • Clause registry

   • Execution permissions

   • Node availability

3. Input Resolver gathers:

   • Sensor values

   • Simulation outputs

   • Credential states

4. TEE Node Selection:

   • Match jurisdictional requirements

   • Validate attestation hash

   • Assign enclave job

5. Execution begins with encrypted payload

6. CAC is generated and signed

7. Proof Aggregator assembles result

8. Rollup Coordinator finalizes multi-CAC bundle

4.10.4 Secure Job Routing and Isolation

NSF routing ensures:

• Job tokens are cryptographically signed

• Payloads are encrypted with enclave-specific keys

• Execution permissions are scoped to job

• Output trace includes job ID and dispatch metadata

Job token example:

{
  "job_id": "clause-exec-0x7812...",
  "clause_id": "WHO::[email protected]",
  "runtime_scope": {
    "jurisdiction": "IDN",
    "dao": "PandemicDAO",
    "trigger_type": "simulation"
  },
  "expiration": "2025-05-01T00:00Z",
  "signature": "0xDEADBEEF..."
}

4.10.5 Execution Redundancy and Consensus Models

Depending on clause priority and risk class, NSF supports:

Execution Mode	Use Case	Quorum
Single-exec TEE	Low-risk, routine clauses	1/1
Multi-exec quorum	Financial / treaty-triggered clauses	2-of-3, 3-of-5
ZK Rollup verifier set	Privacy-critical clauses	All verifiers agree on output hash
Sovereign override model	Disputed clauses	DAO + jurisdiction vote required

This prevents single-node attacks, enforces clause-level consensus, and enables risk-tiered reliability.

---

4.10.6 Dynamic Load Balancing

Schedulers use:

• Job class weightings

• Jurisdictional capacity

• Historical node reliability

• Latency / edge proximity

• TEE attestation freshness

Jobs may be:

• Rescheduled if enclave validation fails

• Paused under high-risk simulation forecast

• Clustered for clause collocation (e.g., flood + health triggers)

---

4.10.7 Governance and Policy Constraints in Orchestration

Every orchestration step checks:

• Clause governance configuration

• DAO permissions

• Clause expiration window

• Credential policy bindings

• Execution window constraints

Failure to pass any check results in:

• Rejection of job

• Governance alert

• Logging to Audit Layer

Example policy: “No clause executions for financial actions may run on non-sovereign nodes.”

---

4.10.8 Rollup Integration and Proof Anchoring

After execution:

• CACs are submitted to Rollup Coordinator

• Merkle root is built

• Aggregate proof is signed by quorum

• State commitment is anchored (optional):

  • On-chain

  • In treaty records

  • In global registry layer

The rollup becomes the source-of-truth for audit and downstream credentials.

---

4.10.9 Failure Handling and Reconciliation

Failures in orchestration (e.g., job dropped, node crash, timeout) are resolved via:

• Retry from fallback node (with new nonce)

• DAO-signed override

• Execution freeze and dispute creation

• Temporal deactivation of affected clause (safe-mode fallback)

Reconciliation actions are:

• Logged

• Verifiable

• Replayable

• Governing body notifiable

4.10.10 Orchestration as a Verifiable Public Compute Fabric

The NSF Orchestration Layer transforms distributed, privacy-sensitive enclaves into:

• A deterministic governance machine

• A public compute mesh for digital policy execution

• A verifiable substrate for multilateral trust

Every clause. Every agent. Every jurisdiction. All orchestrated, all attestable—by design.
