LuxDA Conformance Test Suite

Abstract

This LP defines the conformance test suite for LuxDA Bus implementations, including wire format test vectors and simulation harnesses.

Motivation

This specification formalizes the component design, ensuring consistent implementation across the LuxDA ecosystem.

Specification

1. Test Categories

Category	LPs Covered	Test Count
Header Format	011	50
Block Format	012	30
Relay Protocol	020-022	40
DA API	030-033	60
Storage	040-042	40
Chat Protocol	060-063	80
TFHE	070-075	50
Tokenomics	080-082	20

2. Wire Format Vectors

{
  "header_format_v1": [
    {
      "description": "minimal valid header",
      "input": {
        "namespaceId": "0x0000000000000000000000000000000000000001",
        "seq": 1,
        "timestamp": 1704067200000,
        "blobCommitment": "0x0000...",
        "blobLen": 0
      },
      "expectedBytes": "0x01000000...",
      "expectedHash": "0xabcd..."
    }
  ],
  "mls_welcome_v1": [...],
  "tfhe_sidecar_v1": [...]
}

3. Simulation Harnesses

type SimulationConfig struct {
    // Network topology
    NumNodes     int
    NumRelays    int
    NumDAOps     int

    // Behavior
    MessageRate  int  // per second
    BlobSizes    []int
    FailureRate  float64

    // Duration
    Duration     time.Duration
}

type SimulationResult struct {
    MessagesDelivered int
    AverageLatency    time.Duration
    DASuccess         float64
    Errors            []SimError
}

4. Interoperability Tests

interop_matrix:
  - implementations: [go-luxda, rust-luxda, ts-luxda]
    tests:
      - header_encoding
      - relay_gossip
      - da_dispersal
      - mls_welcome
      - tfhe_encrypt

5. Test Execution

# Run all conformance tests
lux-test conformance --suite all

# Run specific LP tests
lux-test conformance --lp 011

# Run with specific implementation
lux-test conformance --impl go-luxda

# Generate test report
lux-test conformance --report json > results.json

6. Certification

Implementations passing all tests receive certification:

LuxDA Bus Conformance Certificate
Implementation: go-luxda v1.0.0
Date: 2026-01-02
Tests Passed: 370/370
Version: LP-6499 v1.0.0

---

LP-6499 v1.0.0 - 2026-01-02

Rationale

The design follows established patterns in the LuxDA architecture, prioritizing simplicity, security, and interoperability.

Backwards Compatibility

This specification introduces new functionality and does not modify existing protocols. It is fully backwards compatible with existing implementations.

Security Considerations

Implementations must validate all inputs, enforce access controls, and follow the security guidelines established in the LuxDA Bus specification.
