AITBC Feature Gap Roadmap

Executive Summary

The AITBC platform is architecturally complete with all services running, but functionally incomplete. The platform has 35+ feature contexts in the coordinator API, 4 external services (wallet, blockchain-node, marketplace, edge-api), and 264+ registered routes — but many endpoints are stubs returning 200 with empty/mock data.

Service Health Overview

Service	Port	Routes	Working	Stubbed	Status
Coordinator API	8011	264+	~85%	~15%	✅ Mostly Working
Wallet Service	8015	12	12	0	✅ Working
Blockchain Node	8006	20+	20	0	✅ Working
Marketplace	8102	15	15	0	✅ Working
Edge API	8103	30	25	5	✅ Mostly working
AI Engine	8013	8	8	0	✅ Working
GPU Service	8014	10	8	2	✅ Working

Critical Decision Point

The platform needs real blockchain integration — currently wallets are SQLite-only and transactions are mock-signed. Without this, users cannot:

• Create on-chain wallets
• Send/receive tokens
• Stake or participate in consensus
• Execute real DeFi operations

---

Critical Blockers (Cannot Use Platform)

These 8 gaps prevent any meaningful use of the platform:

1. No Real Blockchain Wallet Creation

Aspect	Current	Required	Effort
Problem	Wallets stored in SQLite only; no on-chain addresses	Real key generation + address registration on blockchain	Medium
Impact	Users can't receive tokens or interact with contracts	Full wallet lifecycle management	High
Files	apps/wallet/src/app/keystore/persistent_service.py	Needs blockchain RPC integration
Scenarios Blocked	S01, S02, S14, S26

Technical Details:

• create_wallet() generates keys but doesn't register on chain
• Address derivation exists but no blockchain account creation
• Wallet addresses are not indexed by the blockchain node

Implementation Path:

1. Add blockchain RPC call to register_account(address) in wallet creation flow
2. Ensure blockchain node indexes the new account
3. Update wallet service to track on-chain balance separately from off-chain

---

Testing Strategy

Per-Feature Checklist

Before marking any feature "working":

1. Unit Tests: Core logic tested in isolation
2. Integration Tests: Service-to-service communication
3. End-to-End Tests: Full user flow (CLI → API → Blockchain)
4. Multi-Node Tests: All 3 nodes (genesis, aitbc1, gitea-runner)
5. Documentation: Updated with working examples

Scenario Coverage

Each scenario should have automated test:

# Run specific scenario test
./scripts/workflow/44_comprehensive_multi_node_scenario.sh --scenario S01

# Or run scenario directly via CLI
aitbc-cli scenario run S01 --verify
