L10 Web3 & Rewards Report +Within the MiGrid ecosystem (Platform standard **v10.1.6**, September 2026), the Token Engine operates on version **v4.4.0** as the secure, high-performance Web3 bridge issuing ERC-20 utility tokens ($GRID) on the Polygon network. This weekly run focuses on cross-layer architectural alignment, multi-key payload normalization, and Zero-Trust JWT authentication parity across the stack. + +### Cross-Layer Impact Analysis: +* **L1 Physics Engine (v10.1.6) & Telemetry Parity**: L1's high-fidelity telemetry scoring (separating raw floats from formatted 4-decimal strings) maps directly to L10’s telemetry standards. Standardizing both physics and confidence scores to strict 4-decimal strings (`safeFloat`) is critical for "Proof of Physics equals Proof of Value", preventing decimal rounding drift before rewards are logged and published to the L11 ML Engine training set. To align with L1's site extraction hardening, L10 v4.4.0's `extractSiteId` now searches nested `metadata` objects (`payload.metadata`), preventing site attribution loss during multi-level event processing. +* **L2 Grid Signal (v2.5.6) & L7 Device Gateway (v5.13.0) Alarms**: L7's normalized OCPP 2.1 `NotifyDERAlarm` events and L2's grid lock translator broadcast hardware alarm events across Kafka using various regional key structures (`iso_region`, `isoRegion`, `iso`, `region`). L10 v4.4.0's `DER_ALARM_REPORTED` Kafka consumer has been updated to normalize all regional key formats, ensuring that active regional alarms correctly increment Redis alarm counters (`l4:regional:alarms:`) for dynamic hardware health penalties (-0.05 per active alarm, capped at -0.30). +* **L5 Driver API (v4.1.0) & L6 Engagement Engine (v5.18.0) Security Sync**: To maintain strict Zero-Trust defense across all service entrypoints, L10 v4.4.0 has expanded its token authentication middleware to explicitly block insecure development secrets (`development_secret` and `change_in_production`) under production environments (`process.env.NODE_ENV === 'production'`) with a 500 configuration error. +* **L9 Commerce Engine (v5.1.0) Security Parity**: L9 has hardened multi-tenant fleet isolation by joining charging sessions with vehicle records to verify session ownership by `fleet_id`. In parallel, L10 secures global data training streams (`GET /data/training/rewards`) by rejecting non-administrative/tenant tokens (tokens containing a `fleet_id`), enforcing mTLS and Zero-Trust standards. + +### Smart Contract Lifecycle & Operational Strategy: +* **Open-Wallet Framework Integration**: Seamlessly abstracts private key signatures from end-users, delivering a fast, frictionless Web2 user experience. Gas fees, nonces, and transaction finality on the Polygon network are managed silently via a backend custodial architecture. +* **Secure Private Key Infrastructure**: Preparing the transition from custodial key signatures to a secure Hardware Security Module (HSM) and AWS Key Management Service (KMS) infrastructure to guarantee zero-vulnerability Web3 transaction signing. +* **Edge-Case Resilience (Outage Mitigation)**: To combat potential Polygon RPC node outages or dropped transactions, L10 leverages an asynchronous, gas-optimized batch minting worker. Queued rewards are processed using atomic state transitions (`FOR UPDATE SKIP LOCKED`) to protect against double-spending and guarantee that transient RPC issues do not lead to lost driver rewards. + +--- + +## 2. Backlog Updates +* **P0: Nested Metadata Site Extraction [L10-P6]** — Implemented metadata fallback in `extractSiteId` for complete site ID parity across L1/L2/L10. (Complete) +* **P1: KMS/HSM Private Key Infrastructure [L10-P4]** — Integration of secure transaction-signing infrastructure for production deployments. (Active) +* **P2: ERC-20 Proxy Staking Contract Upgrade [L10-P7]** — Designing a proxy upgrade strategy to introduce non-custodial staking mechanics for drivers. (Planned) +* **P3: Multi-Format DER Alarm Region Normalization [L10-P8]** — Unified regional key extraction across `iso_region`, `isoRegion`, `iso`, and `region`. (Complete) +* **P4: Zero-Trust Token Auth Hardening [L10-SEC-02]** — Expanded weak secret rejection list (`development_secret`, `change_in_production`) for production environments. (Complete) + +--- + +## 3. Engineering Execution (v4.4.0) +This week, we executed critical multi-key extraction hardening and security updates: +* **Version Upgrade**: Upgraded L10 microservice version from `4.3.9` to `4.4.0` inside `package.json`, `/health` check endpoint, and `/data/training/rewards` AI export standard (`source: 'L10_TOKEN_ENGINE_V4.4.0'`). +* **Site ID & Alarm Extraction Hardening**: Refactored `extractSiteId(payload)` in `services/10-token-engine/index.js` to inspect `payload.metadata` as a fallback. Normalized ISO region parsing in `DER_ALARM_REPORTED` Kafka consumer to handle `iso_region`, `isoRegion`, `iso`, and `region` keys. +* **Security Hardening**: Hardened `authenticateToken` middleware in `services/10-token-engine/index.js` to explicitly block `development_secret` and `change_in_production` from being utilized in production environments, returning a 500 error. +* **Unit Tests & Verification**: Updated `services/10-token-engine/tests/security_hardening.test.js` with active assertions for the newly blocked weak secrets, and built `verify_l10_v4_4_0.js` to validate health check status, duplicate function protection, AI export standards, and security hardening. + +**Status**: Operational • **Version**: v4.4.0 • **Platform Standard**: v10.1.6 diff --git a/services/10-token-engine/index.js b/services/10-token-engine/index.js index f32cc1aa..4bdf4f97 100644 --- a/services/10-token-engine/index.js +++ b/services/10-token-engine/index.js @@ -50,7 +50,7 @@ const authenticateToken = (req, res, next) => { // Reject insecure or default keys in production if (process.env.NODE_ENV === 'production' && - (activeSecret === 'test_secret' || activeSecret === 'dev_secret' || activeSecret === 'default_secret' || activeSecret === 'secret' || activeSecret === 'dev_secret_change_in_production')) { + (activeSecret === 'test_secret' || activeSecret === 'dev_secret' || activeSecret === 'default_secret' || activeSecret === 'secret' || activeSecret === 'dev_secret_change_in_production' || activeSecret === 'change_in_production' || activeSecret === 'development_secret')) { console.error('Security Error: Weak JWT_SECRET detected in production environment.'); return res.status(500).json({ error: 'Internal server configuration error: Weak JWT secret in production.' }); } @@ -68,7 +68,7 @@ const authenticateToken = (req, res, next) => { */ function extractSiteId(payload) { if (!payload) return null; - return payload.site_id || payload.siteId || payload.location_id || payload.locationId || null; + return payload.site_id || payload.siteId || payload.location_id || payload.locationId || (payload.metadata ? extractSiteId(payload.metadata) : null) || null; } /** @@ -329,7 +329,7 @@ async function getDynamicMultiplier(isoRaw, actionType, isVppEvent = false) { app.get('/health', (req, res) => { res.json({ service: 'token-engine', - version: '4.3.9', + version: '4.4.0', status: 'healthy', layer: 'L10', platform: 'v10.1.6' @@ -367,7 +367,7 @@ app.get('/data/training/rewards', authenticateToken, async (req, res) => { res.json({ count: result.rows.length, data: result.rows, - source: 'L10_TOKEN_ENGINE_V4.3.9', + source: 'L10_TOKEN_ENGINE_V4.4.0', fidelity_tier: 'SENTINEL' }); } catch (error) { @@ -413,7 +413,7 @@ async function start() { } if (topic === 'DER_ALARM_REPORTED') { - const alarmRegion = (payload.iso_region || 'SYSTEM_WIDE').toUpperCase().replace(/-/g, ''); + const alarmRegion = (payload.iso_region || payload.isoRegion || payload.iso || payload.region || 'SYSTEM_WIDE').toUpperCase().replace(/-/g, ''); const alarms = payload.alarms || []; console.log(`🚨 [L10 Alarm Tracker] DER Alarm reported from ${payload.chargePointId} in ${alarmRegion}.
