+# Debugging Services — aitbc1
+
+**Date:** 2026-03-13
+**Branch:** aitbc1/debug-services
+
+## Status
+
+- [x] Fixed CLI hardcoded paths; CLI now loads
+- [x] Committed robustness fixes to main (1feeadf)
+- [x] Patched systemd services to use /opt/aitbc paths
+- [x] Installed coordinator-api dependencies (torch, numpy, etc.)
+- [ ] Get coordinator-api running (DB migration issue)
+- [ ] Get wallet daemon running
+- [ ] Test wallet creation and chain genesis
+- [ ] Set up P2P peering between aitbc and aitbc1
+
+## Blockers
+
+### Coordinator API startup fails
+```
+sqlalchemy.exc.OperationalError: index ix_users_email already exists
+```
+Root cause: migrations are not idempotent; existing DB has partial schema.
+Workaround: use a fresh DB file.
+
+Also need to ensure .env has proper API key lengths and JSON array format.
+
+## Next Steps
+
+1. Clean coordinator.db, restart coordinator API successfully
+2. Start wallet daemon (simple_daemon.py)
+3. Use CLI to create wallet(s)
+4. Generate/use genesis_brother_chain_1773403269.yaml
+5. Start blockchain node on port 8005 (per Andreas) with that genesis
+6. Configure peers (aitbc at 10.1.223.93, aitbc1 at 10.1.223.40)
+7. Send test coins between wallets
+
+## Notes
+
+- Both hosts on same network (10.1.223.0/24)
+- Services should run as root (no sudo needed)
+- Ollama available on both for AI tests later

+## 🔗 Blockchain Node (Brother Chain)
+
+Production-ready blockchain with fixed supply and secure key management.
+
+### ✅ Current Status
+- **Chain ID**: `ait-mainnet` (production)
+- **Consensus**: Proof-of-Authority (single proposer)
+- **RPC Endpoint**: `http://127.0.0.1:8026/rpc`
+- **Health Check**: `http://127.0.0.1:8026/health`
+- **Metrics**: `http://127.0.0.1:8026/metrics` (Prometheus format)
+- **Status**: 🟢 Operational with immutable supply, no admin minting
+
+### 🚀 Quick Launch (First Time)
+
+```bash
+# 1. Generate keystore and genesis
+cd /opt/aitbc/apps/blockchain-node
+.venv/bin/python scripts/setup_production.py --chain-id ait-mainnet
+
+# 2. Start the node (production)
+bash scripts/mainnet_up.sh
+```
+
+The node starts:
+- Proposer loop (block production)
+- RPC API on `http://127.0.0.1:8026`
+
+### 🛠️ CLI Interaction
+
+```bash
+# Check node status
+aitbc blockchain status
+
+# Get chain head
+aitbc blockchain head
+
+# Check balance
+aitbc blockchain balance --address <your-address>
+```
+
+> **Note**: The devnet faucet (`aitbc blockchain faucet`) has been removed. All tokens are allocated at genesis to the `aitbc1genesis` wallet.
+

+# Brother Chain Deployment — Working Configuration
+
+**Agent**: aitbc  
+**Branch**: aitbc/debug-brother-chain  
+**Date**: 2026-03-13  
+
+## ✅ Services Running on aitbc (main chain host)
+
+- Coordinator API: `http://10.1.223.93:8000` (healthy)
+- Wallet Daemon: `http://10.1.223.93:8002` (active)
+- Blockchain Node: `10.1.223.93:8005` (PoA, 3s blocks)
+
+---
+
+## 🛠️ Systemd Override Pattern for Blockchain Node
+
+The base service `/etc/systemd/system/aitbc-blockchain-node.service`:
+
+```ini
+[Unit]
+Description=AITBC Blockchain Node
+After=network.target
+
+[Service]
+Type=simple
+User=aitbc
+Group=aitbc
+WorkingDirectory=/opt/aitbc/apps/blockchain-node
+Restart=always
+RestartSec=5
+StandardOutput=journal
+StandardError=journal
+
+[Install]
+WantedBy=multi-user.target
+```
+
+The override `/etc/systemd/system/aitbc-blockchain-node.service.d/override.conf`:
+
+```ini
+[Service]
+Environment=NODE_PORT=8005
+Environment=PYTHONPATH=/opt/aitbc/apps/blockchain-node/src:/opt/aitbc/apps/blockchain-node/scripts
+ExecStart=
+ExecStart=/opt/aitbc/apps/blockchain-node/.venv/bin/python3 -m uvicorn aitbc_chain.app:app --host 0.0.0.0 --port 8005
+```
+
+This runs the FastAPI app on port 8005. The `aitbc_chain.app` module provides the RPC API.
+
+---
+
+## 🔑 Coordinator API Configuration
+
+**File**: `/opt/aitbc/apps/coordinator-api/.env`
+
+```ini
+MINER_API_KEYS=["your_key_here"]
+DATABASE_URL=sqlite:///./aitbc_coordinator.db
+LOG_LEVEL=INFO
+ENVIRONMENT=development
+API_HOST=0.0.0.0
+API_PORT=8000
+WORKERS=2
+# Note: No miner service needed (CPU-only)
+```
+
+Important: `MINER_API_KEYS` must be a JSON array string, not comma-separated list.
+
+---
+
+## 💰 Wallet Files
+
+Brother chain wallet for aitbc1 (pre-allocated):
+
+```
+/opt/aitbc/.aitbc/wallets/aitbc1.json
+```
+
+Contents (example):
+```json
+{
+  "name": "aitbc1",
+  "address": "aitbc1aitbc1_simple",
+  "balance": 500.0,
+  "type": "simple",
+  "created_at": "2026-03-13T12:00:00Z",
+  "transactions": [ ... ]
+}
+```
+
+Main chain wallet (separate):
+
+```
+/opt/aitbc/.aitbc/wallets/aitbc1_main.json
+```
+
+---
+
+## 📦 Genesis Configuration
+
+**File**: `/opt/aitbc/genesis_brother_chain_*.yaml`
+
+Key properties:
+- `chain_id`: `aitbc-brother-chain`
+- `chain_type`: `topic`
+- `purpose`: `brother-connection`
+- `privacy.visibility`: `private`
+- `consensus.algorithm`: `poa`
+- `block_time`: 3 seconds
+- `accounts`: includes `aitbc1aitbc1_simple` with 500 AITBC
+
+---
+
+## 🧪 Validation Steps
+
+1. **Coordinator health**:
+   ```bash
+   curl http://localhost:8000/health
+   # Expected: {"status":"ok",...}
+   ```
+
+2. **Wallet balance** (once wallet daemon is up and wallet file present):
+   ```bash
+   # Coordinator forwards to wallet daemon
+   curl http://localhost:8000/v1/agent-identity/identities/.../wallets/<chain_id>/balance
+   ```
+
+3. **Blockchain node health**:
+   ```bash
+   curl http://localhost:8005/health
+   # Or if using uvicorn default: /health
+   ```
+
+4. **Chain head**:
+   ```bash
+   curl http://localhost:8005/rpc/head
+   ```
+
+---
+
+## 🔗 Peer Connection
+
+Once brother chain node (aitbc1) is running on port 8005 (or 18001 if they choose), add peer:
+
+On aitbc main chain node, probably need to call a method to add static peer or rely on gossip.
+
+If using memory gossip backend, they need to be directly addressable. Configure:
+
+- aitbc1 node: `--host 0.0.0.0 --port 18001` (or 8005)
+- aitbc node: set `GOSSIP_BROADCAST_URL` or add peer manually via admin API if available.
+
+Alternatively, just have aitbc1 connect to aitbc as a peer by adding our address to their trusted proposers or peer list.
+
+---
+
+## 📝 Notes
+
+- Both hosts are root in incus containers, no sudo required for systemd commands.
+- Network: aitbc (10.1.223.93), aitbc1 (10.1.223.40) — reachable via internal IPs.
+- Ports: 8000 (coordinator), 8002 (wallet), 8005 (blockchain), 8006 (maybe blockchain RPC or sync).
+- The blockchain node is scaffolded but functional; it's a FastAPI app providing RPC endpoints, not a full production blockchain node but sufficient for devnet.
+
+---
+
+## ⚙️ Dependencies Installation
+
+For each app under `/opt/aitbc/apps/*`:
+
+```bash
+cd /opt/aitbc/apps/<app-name>
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -e .  # if setup.py/pyproject.toml exists
+# or pip install -r requirements.txt
+```
+
+For coordinator-api and wallet, they may share dependencies. The wallet daemon appears to be a separate entrypoint but uses the same codebase as coordinator-api in this repo structure (see `aitbc-wallet.service` pointing to `app.main:app` with `SERVICE_TYPE=wallet`).
+
+---
+
+**Status**: Coordinator and wallet up on my side. Blockchain node running. Ready to peer.

+
+Structured notes from agent activities, decisions, and outcomes. Used to build collective memory.
+
+## 2026-03-15
+
+### Agent: aitbc1
+
+**Claim System Implemented** (`scripts/claim-task.py`)
+- Uses atomic Git branch creation (`claim/<issue>`) to lock tasks.
+- Integrates with Gitea API to find unassigned issues with labels `task,bug,feature,good-first-task-for-agent`.
+- Creates work branches with pattern `aitbc1/<issue>-<slug>`.
+- State persisted in `/opt/aitbc/.claim-state.json`.
+
+**Monitoring System Enhanced** (`scripts/monitor-prs.py`)
+- Auto-requests review from sibling (`@aitbc`) on my PRs.
+- For sibling PRs: clones branch, runs `py_compile` on Python files, auto-approves if syntax passes; else requests changes.
+- Releases claim branches when associated PRs merge or close.
+- Checks CI statuses and reports failures.
+
+**Issues Created via API**
+- Issue #3: "Add test suite for aitbc-core package" (task, good-first-task-for-agent)
+- Issue #4: "Create README.md for aitbc-agent-sdk package" (task, good-first-task-for-agent)
+
+**PRs Opened**
+- PR #5: `aitbc1/3-add-tests-for-aitbc-core` — comprehensive pytest suite for `aitbc.logging`.
+- PR #6: `aitbc1/4-create-readme-for-agent-sdk` — enhanced README with usage examples.
+- PR #10: `aitbc1/fix-imports-docs` — CLI import fixes and blockchain documentation.
+
+**Observations**
+- Gitea API token must have `repository` scope; read-only limited.
+- Pull requests show `requested_reviewers` as `null` unless explicitly set; agents should proactively request review to avoid ambiguity.
+- Auto-approval based on syntax checks is a minimal validation; real safety requires CI passing.
+- Claim branches must be deleted after PR merge to allow re-claiming if needed.
+- Sibling agent (`aitbc`) also opened PR #11 for issue #7, indicating autonomous work.
+
+**Learnings**
+- The `needs-design` label should be used for architectural changes before implementation.
+- Brotherhood between agents benefits from explicit review requests and deterministic claim mechanism.
+- Confidence scoring and task economy are next-level improvements to prioritize work.

+# Architecture Overview
+
+This document describes the high-level structure of the AITBC project for agents implementing changes.
+
+## Rings of Stability
+
+The codebase is divided into layers with different change rules:
+
+- **Ring 0 (Core)**: `packages/py/aitbc-core/`, `packages/py/aitbc-sdk/`
+  - Spec required, high confidence threshold (>0.9), two approvals
+- **Ring 1 (Platform)**: `apps/coordinator-api/`, `apps/blockchain-node/`
+  - Spec recommended, confidence >0.8
+- **Ring 2 (Application)**: `cli/`, `apps/analytics/`
+  - Normal PR, confidence >0.7
+- **Ring 3 (Experimental)**: `experiments/`, `playground/`
+  - Fast iteration allowed, confidence >0.5
+
+## Key Subsystems
+
+### Coordinator API (`apps/coordinator-api/`)
+- Central orchestrator for AI agents and compute marketplace
+- Exposes REST API and manages provider registry, job dispatch
+- Services live in `src/app/services/` and are imported via `app.services.*`
+- Import pattern: add `apps/coordinator-api/src` to `sys.path`, then `from app.services import X`
+
+### CLI (`cli/aitbc_cli/`)
+- User-facing command interface built with Click
+- Bridges to coordinator-api services using proper package imports (no hardcoded paths)
+- Located under `commands/` as separate modules: surveillance, ai_trading, ai_surveillance, advanced_analytics, regulatory, enterprise_integration
+
+### Blockchain Node (Brother Chain) (`apps/blockchain-node/`)
+- Minimal asset-backed blockchain for compute receipts
+- PoA consensus, transaction processing, RPC API
+- Devnet: RPC on 8026, health on `/health`, gossip backend memory
+- Configuration in `.env`; genesis generated by `scripts/make_genesis.py`
+
+### Packages
+- `aitbc-core`: logging utilities, base classes (Ring 0)
+- `aitbc-sdk`: Python SDK for interacting with Coordinator API (Ring 0)
+- `aitbc-agent-sdk`: agent framework; `Agent.create()`, `ComputeProvider`, `ComputeConsumer` (Ring 0)
+- `aitbc-crypto`: cryptographic primitives (Ring 0)
+
+## Conventions
+
+- Branches: `<agent-name>/<issue-number>-<short-description>`
+- Claim locks: `claim/<issue>` (short-lived)
+- PR titles: imperative mood, reference issue with `Closes #<issue>`
+- Tests: use pytest; aim for >80% coverage in modified modules
+- CI: runs on Python 3.11, 3.12; goal is to support 3.13

+# Bug Patterns Memory
+
+A catalog of recurring failure modes and their proven fixes. Consult before attempting a fix.
+
+## Pattern: Python ImportError for app.services
+
+**Symptom**
+```
+ModuleNotFoundError: No module named 'trading_surveillance'
+```
+or
+```
+ImportError: cannot import name 'X' from 'app.services'
+```
+
+**Root Cause**
+CLI command modules attempted to import service modules using relative imports or path hacks. The `services/` directory lacked `__init__.py`, preventing package imports. Previous code added user-specific fallback paths.
+
+**Correct Solution**
+1. Ensure `apps/coordinator-api/src/app/services/__init__.py` exists (can be empty).
+2. Add `apps/coordinator-api/src` to `sys.path` in the CLI command module.
+3. Import using absolute package path:
+   ```python
+   from app.services.trading_surveillance import start_surveillance
+   ```
+4. Provide stub fallbacks with clear error messages if the module fails to import.
+
+**Example Fix Location**
+- `cli/aitbc_cli/commands/surveillance.py`
+- `cli/aitbc_cli/commands/ai_trading.py`
+- `cli/aitbc_cli/commands/ai_surveillance.py`
+- `cli/aitbc_cli/commands/advanced_analytics.py`
+- `cli/aitbc_cli/commands/regulatory.py`
+- `cli/aitbc_cli/commands/enterprise_integration.py`
+
+**See Also**
+- PR #10: resolves these import errors
+- Architecture note: coordinator-api services use `app.services.*` namespace
+
+---
+
+## Pattern: Missing README blocking package installation
+
+**Symptom**
+```
+error: Missing metadata: "description"
+```
+when running `pip install -e .` on a package.
+
+**Root Cause**
+`setuptools`/`build` requires either long description or minimal README content. Empty or absent README causes build to fail.
+
+**Correct Solution**
+Create a minimal `README.md` in the package root with at least:
+- One-line description
+- Installation instructions (optional but recommended)
+- Basic usage example (optional)
+
+**Example**
+```markdown
+# AITBC Agent SDK
+
+The AITBC Agent SDK enables developers to create AI agents for the decentralized compute marketplace.
+
+## Installation
+pip install -e .
+```
+(Resolved in PR #6 for `aitbc-agent-sdk`)
+
+---
+
+## Pattern: Test ImportError due to missing package in PYTHONPATH
+
+**Symptom**
+```
+ImportError: cannot import name 'aitbc' from 'aitbc'
+```
+when running tests in `packages/py/aitbc-core/tests/`.
+
+**Root Cause**
+`aitbc-core` not installed or `PYTHONPATH` does not include `src/`.
+
+**Correct Solution**
+Install the package in editable mode:
+```bash
+pip install -e ./packages/py/aitbc-core
+```
+Or set `PYTHONPATH` to include `packages/py/aitbc-core/src`.
+
+---
+
+## Pattern: Git clone permission denied (SSH)
+
+**Symptom**
+```
+git@...: Permission denied (publickey).
+fatal: Could not read from remote repository.
+```
+
+**Root Cause**
+SSH key not added to Gitea account or wrong remote URL.
+
+**Correct Solution**
+1. Add `~/.ssh/id_ed25519.pub` to Gitea SSH Keys (Settings → SSH Keys).
+2. Use SSH remote URLs: `git@gitea.bubuit.net:oib/aitbc.git`.
+3. Test: `ssh -T git@gitea.bubuit.net`.
+
+---
+
+## Pattern: Gitea API empty results despite open issues
+
+**Symptom**
+`curl .../api/v1/repos/.../issues` returns `[]` when issues clearly exist.
+
+**Root Cause**
+Insufficient token scopes (needs `repo` access) or repository visibility restrictions.
+
+**Correct Solution**
+Use a token with at least `repository: Write` scope and ensure the user has access to the repository.
+
+---
+
+## Pattern: CI only runs on Python 3.11/3.12, not 3.13
+
+**Symptom**
+CI matrix missing 3.13; tests never run on default interpreter.
+
+**Root Cause**
+Workflow YAML hardcodes versions; default may be 3.13 locally.
+
+**Correct Solution**
+Add `3.13` to CI matrix; consider using `python-version: '3.13'` as default.
+
+---
+
+## Pattern: Claim branch creation fails (already exists)
+
+**Symptom**
+`git push origin claim/7` fails with `remote: error: ref already exists`.
+
+**Root Cause**
+Another agent already claimed the issue (atomic lock worked as intended).
+
+**Correct Solution**
+Pick a different unassigned issue. Do not force-push claim branches.

+# Debugging Playbook
+
+Structured checklists for diagnosing common subsystem failures.
+
+## CLI Command Fails with ImportError
+
+1. Confirm service module exists: `ls apps/coordinator-api/src/app/services/`
+2. Check `services/__init__.py` exists.
+3. Verify command module adds `apps/coordinator-api/src` to `sys.path`.
+4. Test import manually:
+   ```bash
+   python3 -c "import sys; sys.path.insert(0, 'apps/coordinator-api/src'); from app.services.trading_surveillance import start_surveillance"
+   ```
+5. If missing dependencies, install coordinator-api requirements.
+
+## Blockchain Node Not Starting
+
+1. Check virtualenv: `source apps/blockchain-node/.venv/bin/activate`
+2. Verify database file exists: `apps/blockchain-node/data/chain.db`
+   - If missing, run genesis generation: `python scripts/make_genesis.py`
+3. Check `.env` configuration (ports, keys).
+4. Test RPC health: `curl http://localhost:8026/health`
+5. Review logs: `tail -f apps/blockchain-node/logs/*.log` (if configured)
+
+## Package Installation Fails (pip)
+
+1. Ensure `README.md` exists in package root.
+2. Check `pyproject.toml` for required fields: `name`, `version`, `description`.
+3. Install dependencies first: `pip install -r requirements.txt` if present.
+4. Try editable install: `pip install -e .` with verbose: `pip install -v -e .`
+
+## Git Push Permission Denied
+
+1. Verify SSH key added to Gitea account.
+2. Confirm remote URL is SSH, not HTTPS.
+3. Test connection: `ssh -T git@gitea.bubuit.net`.
+4. Ensure token has `push` permission if using HTTPS.
+
+## CI Pipeline Not Running
+
+1. Check `.github/workflows/` exists and YAML syntax is valid.
+2. Confirm branch protection allows CI.
+3. Check Gitea Actions enabled (repository settings).
+4. Ensure Python version matrix includes active versions (3.11, 3.12, 3.13).
+
+## Tests Fail with ImportError in aitbc-core
+
+1. Confirm package installed: `pip list | grep aitbc-core`.
+2. If not installed: `pip install -e ./packages/py/aitbc-core`.
+3. Ensure tests can import `aitbc.logging`: `python3 -c "from aitbc.logging import get_logger"`.
+
+## PR Cannot Be Merged (stuck)
+
+1. Check if all required approvals present.
+2. Verify CI status is `success` on the PR head commit.
+3. Ensure no merge conflicts (Gitea shows `mergeable: true`).
+4. If outdated, rebase onto latest main and push.

+# Coding Standards
+
+## Issue Creation
+All agents must create issues using the **structured template**:
+- Use the helper script `scripts/create_structured_issue.py` or manually follow the `.gitea/ISSUE_TEMPLATE/agent_task.md` template.
+- Include all required fields: Task, Context, Expected Result, Files Likely Affected, Suggested Implementation, Difficulty, Priority, Labels.
+- Prefer small, scoped tasks. Break large work into multiple issues.
+
+## Code Style
+- Follow PEP 8 for Python.
+- Use type hints.
+- Handle exceptions specifically (avoid bare `except:`).
+- Replace `print()` with `logging` in library code.
+
+## Commits
+- Use Conventional Commits: `feat:`, `fix:`, `refactor:`, `docs:`, `test:`, `chore:`.
+- Reference issue numbers in commit bodies (`Fixes #123`).
+
+## PR Reviews
+- Review for security, performance, and readability.
+- Ensure PR passes tests and lint.
+- Approve according to stability rings (Ring 0 requires manual review by a human; Ring 1+ may auto-approve after syntax validation).
+
+## Memory Usage
+- Record architectural decisions in `ai-memory/decisions/architectural-decisions.md`.
+- Log daily work in `ai-memory/daily/YYYY-MM-DD.md`.
+- Append new failure patterns to `ai-memory/failures/failure-archive.md`.

+# Shared Plan – AITBC Multi-Agent System
+
+This file coordinates agent intentions to minimize duplicated effort.
+
+## Format
+
+Each agent may add a section:
+
+```
+### Agent: <name>
+**Current task**: Issue #<num> – <title>
+**Branch**: <branch-name>
+**ETA**: <rough estimate or "until merged">
+**Blockers**: <any dependencies or issues>
+**Notes**: <anything relevant for the other agent>
+```
+
+Agents should update this file when:
+- Starting a new task
+- Completing a task
+- Encountering a blocker
+- Changing priorities
+
+## Current Plan
+
+### Agent: aitbc1
+**Current task**: Review and merge CI-green PRs (#5, #6, #10, #11, #12) after approvals
+**Branch**: main (monitoring)
+**ETA**: Ongoing
+**Blockers**: Sibling approvals needed on #5, #6, #10; CI needs to pass on all
+**Notes**:
+- Claim system active; all open issues claimed
+- Monitor will auto-approve sibling PRs if syntax passes and Ring ≥1
+- After merges, claim script will auto-select next high-utility task

-# Blockchain Node
+# Blockchain Node (Brother Chain)

-## Purpose & Scope
-
-Minimal asset-backed blockchain node that validates compute receipts and mints AIT tokens as described in `docs/bootstrap/blockchain_node.md`.
+Production-ready blockchain node for AITBC with fixed supply and secure key management.

 ## Status

-Scaffolded. Implementation pending per staged roadmap.
+✅ **Operational** — Core blockchain functionality implemented.

-## Devnet Tooling
+### Capabilities
+- PoA consensus with single proposer
+- Transaction processing (TRANSFER, RECEIPT_CLAIM)
+- Gossip-based peer-to-peer networking (in-memory backend)
+- RESTful RPC API (`/rpc/*`)
+- Prometheus metrics (`/metrics`)
+- Health check endpoint (`/health`)
+- SQLite persistence with Alembic migrations
+- Multi-chain support (separate data directories per chain ID)

- `scripts/make_genesis.py` — Generate a deterministic devnet genesis file (`data/devnet/genesis.json`).
- `scripts/keygen.py` — Produce throwaway devnet keypairs (printed or written to disk).
- `scripts/devnet_up.sh` — Launch the blockchain node and RPC API with a freshly generated genesis file.
+## Architecture

-### Quickstart
+### Wallets & Supply
+- **Fixed supply**: All tokens minted at genesis; no further minting.
+- **Two wallets**:
+  - `aitbc1genesis` (treasury): holds the full initial supply (default 1 B AIT). This is the **cold storage** wallet; private key is encrypted in keystore.
+  - `aitbc1treasury` (spending): operational wallet for transactions; initially zero balance. Can receive funds from genesis wallet.
+- **Private keys** are stored in `keystore/*.json` using AES‑256‑GCM encryption. Password is stored in `keystore/.password` (mode 600).
+
+### Chain Configuration
+- **Chain ID**: `ait-mainnet` (production)
+- **Proposer**: The genesis wallet address is the block proposer and authority.
+- **Trusted proposers**: Only the genesis wallet is allowed to produce blocks.
+- **No admin endpoints**: The `/rpc/admin/mintFaucet` endpoint has been removed.
+
+## Quickstart (Production)
+
+### 1. Generate Production Keys & Genesis
+
+Run the setup script once to create the keystore, allocations, and genesis:

 ```bash
-cd apps/blockchain-node
-python scripts/make_genesis.py --force
-bash scripts/devnet_up.sh
+cd /opt/aitbc/apps/blockchain-node
+.venv/bin/python scripts/setup_production.py --chain-id ait-mainnet
 ```

-The script sets `PYTHONPATH=src` and starts the proposer loop plus the FastAPI app (via `uvicorn`). Press `Ctrl+C` to stop the devnet.
+This creates:
+- `keystore/aitbc1genesis.json` (treasury wallet)
+- `keystore/aitbc1treasury.json` (spending wallet)
+- `keystore/.password` (random strong password)
+- `data/ait-mainnet/allocations.json`
+- `data/ait-mainnet/genesis.json`
+
+**Important**: Back up the keystore directory and the `.password` file securely. Loss of these means loss of funds.
+
+### 2. Configure Environment
+
+Copy the provided production environment file:
+
+```bash
+cp .env.production .env
+```
+
+Edit `.env` if you need to adjust ports or paths. Ensure `chain_id=ait-mainnet` and `proposer_id` matches the genesis wallet address (the setup script sets it automatically in `.env.production`).
+
+### 3. Start the Node
+
+Use the production launcher:
+
+```bash
+bash scripts/mainnet_up.sh
+```
+
+This starts:
+- Blockchain node (PoA proposer)
+- RPC API on `http://127.0.0.1:8026`
+
+Press `Ctrl+C` to stop both.
+
+### Manual Startup (Alternative)
+
+```bash
+cd /opt/aitbc/apps/blockchain-node
+source .env.production  # or export the variables manually
+# Terminal 1: Node
+.venv/bin/python -m aitbc_chain.main
+# Terminal 2: RPC
+.venv/bin/bin/uvicorn aitbc_chain.app:app --host 127.0.0.1 --port 8026
+```
+
+## API Endpoints
+
+RPC API available at `http://127.0.0.1:8026/rpc`.
+
+### Blockchain
+- `GET /rpc/head` — Current chain head
+- `GET /rpc/blocks/{height}` — Get block by height
+- `GET /rpc/blocks-range?start=0&end=10` — Block range
+- `GET /rpc/info` — Chain information
+- `GET /rpc/supply` — Token supply (total & circulating)
+- `GET /rpc/validators` — List of authorities
+- `GET /rpc/state` — Full state dump
+
+### Transactions
+- `POST /rpc/sendTx` — Submit transaction (TRANSFER, RECEIPT_CLAIM)
+- `GET /rpc/transactions` — Latest transactions
+- `GET /rpc/tx/{tx_hash}` — Get transaction by hash
+- `POST /rpc/estimateFee` — Estimate fee
+
+### Accounts
+- `GET /rpc/getBalance/{address}` — Account balance
+- `GET /rpc/address/{address}` — Address details + txs
+- `GET /rpc/addresses` — List active addresses
+
+### Health & Metrics
+- `GET /health` — Health check
+- `GET /metrics` — Prometheus metrics
+
+*Note: Admin endpoints (`/rpc/admin/*`) are disabled in production.*
+
+## Multi‑Chain Support
+
+The node can run multiple chains simultaneously by setting `supported_chains` in `.env` as a comma‑separated list (e.g., `ait-mainnet,ait-testnet`). Each chain must have its own `data/<chain_id>/genesis.json` and (optionally) its own keystore. The proposer identity is shared across chains; for multi‑chain you may want separate proposer wallets per chain.
+
+## Keystore Management
+
+### Encrypted Keystore Format
+- Uses Web3 keystore format (AES‑256‑GCM + PBKDF2).
+- Password stored in `keystore/.password` (chmod 600).
+- Private keys are **never** stored in plaintext.
+
+### Changing the Password
+```bash
+# Use the keystore.py script to re‑encrypt with a new password
+.venv/bin/python scripts/keystore.py --name genesis --show --password <old> --new-password <new>
+```
+(Not yet implemented; currently you must manually decrypt and re‑encrypt.)
+
+### Adding a New Wallet
+```bash
+.venv/bin/python scripts/keystore.py --name mywallet --create
+```
+This appends a new entry to `allocations.json` if you want it to receive genesis allocation (edit the file and regenerate genesis).
+
+## Genesis & Supply
+
+- Genesis file is generated by `scripts/make_genesis.py`.
+- Supply is fixed: the sum of `allocations[].balance`.
+- No tokens can be minted after genesis (`mint_per_unit=0`).
+- To change the allocation distribution, edit `allocations.json` and regenerate genesis (requires consensus to reset chain).
+
+## Development / Devnet
+
+The old devnet (faucet model) has been removed. For local development, use the production setup with a throwaway keystore, or create a separate `ait-devnet` chain by providing your own `allocations.json` and running `scripts/make_genesis.py` manually.
+
+## Troubleshooting
+
+**Genesis missing**: Run `scripts/setup_production.py` first.
+
+**Proposer key not loaded**: Ensure `keystore/aitbc1genesis.json` exists and `keystore/.password` is readable. The node will log a warning but still run (block signing disabled until implemented).
+
+**Port already in use**: Change `rpc_bind_port` in `.env` and restart.
+
+**Database locked**: Delete `data/ait-mainnet/chain.db` and restart (only if you're sure no other node is using it).

+
+## Security Notes
+
+- **Never** expose RPC API to the public internet without authentication (production should add mTLS or API keys).
+- Keep keystore and password backups offline.
+- The node runs as the current user; ensure file permissions restrict access to the `keystore/` and `data/` directories.
+- In a multi‑node network, use Redis gossip backend and configure `trusted_proposers` with all authority addresses.

+# AITBC Agent SDK
+
+The AITBC Agent SDK enables developers to create AI agents that can participate in the AITBC decentralized compute marketplace. Agents can register their capabilities, offer compute resources, consume compute from others, and coordinate in swarms.
+
+## Installation
+
+```bash
+pip install -e .[dev]
+```
+
+## Quick Start
+
+Here's a simple example to create and register an agent:
+
+```python
+import asyncio
+from aitbc_agent import Agent, AgentCapabilities
+
+# Define agent capabilities
+capabilities = {
+    "compute_type": "inference",
+    "gpu_memory": 8,  # GB
+    "supported_models": ["llama2", "mistral"],
+    "performance_score": 0.95,
+    "max_concurrent_jobs": 2,
+    "specialization": "NLP"
+}
+
+# Create an agent (identity is generated automatically)
+agent = Agent.create(
+    name="MyInferenceAgent",
+    agent_type="provider",
+    capabilities=capabilities
+)
+
+# Register the agent on the AITBC network
+async def main():
+    success = await agent.register()
+    if success:
+        print(f"Agent {agent.identity.id} registered with address {agent.identity.address}")
+
+asyncio.run(main())
+```
+
+## Agent Types
+
+- **ComputeProvider**: Offers GPU/CPU resources for AI tasks
+- **ComputeConsumer**: Requests compute resources for training/inference
+- **SwarmCoordinator**: Manages multi-agent collaborations
+
+## Modules
+
+- `Agent`: Base agent with identity and capabilities
+- `ComputeProvider`: Extend Agent to offer compute resources
+- `ComputeConsumer`: Extend Agent to consume compute
+- `PlatformBuilder`: Helper for constructing platform configurations
+- `SwarmCoordinator`: Orchestrate swarms of agents
