Role of verifier nodes
Verifier nodes perform four primary functions in the Kwala network:| Function | Description |
|---|---|
| Re-compute workflow logic | Independently execute workflow logic based on the original user intent |
| Compare outputs | Compare actual output of executor nodes with expected outcome |
| File disputes | Submit disputes to Kalp Chain’s arbitration contract in case of deviation |
| Periodic auditing | Run periodically or via randomly assigned rounds for high-value workflows |
Verification process
Execution proof retrieval
Verifier nodes retrieve execution proofs submitted by executor nodes from Kalp Chain. These proofs contain all inputs, outputs, and state transitions from the workflow execution.
Intent reconstruction
The verifier retrieves the original user-signed workflow intent from the chain and reconstructs the expected execution path.
Independent re-computation
Using the same inputs and trigger data, the verifier independently re-computes the workflow logic to determine the expected outcome.
Result comparison
The verifier compares its computed result against the executor’s submitted proof. Any discrepancy triggers the dispute process.
Security guarantees
Verifier nodes provide several security guarantees to the Kwala network:- Non-repudiation: Users cannot deny their signed intents
- Execution fidelity: Executors cannot deviate from defined workflows
- Transparency: All verifications are recorded on-chain
- Accountability: Malicious actors face economic penalties
