# Blockchain Node (Brother Chain)
Minimal asset-backed blockchain node that validates compute receipts and mints AIT tokens.
Production-ready blockchain node for AITBC with fixed supply and secure key management.
## Status
✅ **Operational** — Core blockchain functionality implemented and running.
✅ **Operational** — Core blockchain functionality implemented.
### Capabilities
- PoA consensus with single proposer (devnet)
- PoA consensus with single proposer
- Transaction processing (TRANSFER, RECEIPT_CLAIM)
- Receipt validation and minting
- 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)
## Quickstart (Devnet)
## Architecture
The blockchain node is already set up with a virtualenv. To launch:
### 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 /opt/aitbc/apps/blockchain-node
source .venv/bin/activate
bash scripts/devnet_up.sh
.venv/bin/python scripts/setup_production.py --chain-id ait-mainnet
```
This will:
1. Generate genesis block at `data/devnet/genesis.json`
2. Start the blockchain node proposer loop (PID logged)
3. Start RPC API on `http://127.0.0.1:8026`
4. Start mock coordinator on `http://127.0.0.1:8090`
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`
Press `Ctrl+C` to stop all processes.
**Important**: Back up the keystore directory and the `.password` file securely. Loss of these means loss of funds.
### Manual Startup
### 2. Configure Environment
If you prefer to start components separately:
Copy the provided production environment file:
```bash
# Terminal 1: Blockchain node
cd /opt/aitbc/apps/blockchain-node
source .venv/bin/activate
PYTHONPATH=src python -m aitbc_chain.main
cp .env.production .env
```
# Terminal 2: RPC API
cd /opt/aitbc/apps/blockchain-node
source .venv/bin/activate
PYTHONPATH=src uvicorn aitbc_chain.app:app --host 127.0.0.1 --port 8026
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`).
# Terminal 3: Mock coordinator (optional, for testing)
### 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 .venv/bin/activate
PYTHONPATH=src uvicorn mock_coordinator:app --host 127.0.0.1 --port 8090
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
Once running, the RPC API is available at `http://127.0.0.1:8026/rpc`.

## CLI Integration
## Multi‑Chain Support
Use the AITBC CLI to interact with the node:
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
source /opt/aitbc/cli/venv/bin/activate
aitbc blockchain status
aitbc blockchain head
aitbc blockchain balance --address <your-address>
aitbc blockchain faucet --address <your-address> --amount 1000
# 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.)
## Configuration
Edit `.env` in this directory to change:
```
CHAIN_ID=ait-devnet
DB_PATH=./data/chain.db
RPC_BIND_HOST=0.0.0.0
RPC_BIND_PORT=8026
P2P_BIND_HOST=0.0.0.0
P2P_BIND_PORT=7070
PROPOSER_KEY=proposer_key_<timestamp>
MINT_PER_UNIT=1000
COORDINATOR_RATIO=0.05
GOSSIP_BACKEND=memory
### 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).
Restart the node after changes.
## 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).

## Notes
## Security Notes
- The node uses proof-of-authority (PoA) consensus with a single proposer for the devnet.
- Transactions require a valid signature (ed25519) unless running in test mode.
- Receipts represent compute work attestations and mint new AIT tokens to the miner.
- Gossip backend defaults to in-memory; for multi-node networks, configure a Redis backend.
- RPC API does not require authentication on devnet (add in production).
## Troubleshooting
**Port already in use:** Change `RPC_BIND_PORT` in `.env` and restart.
**Database locked:** Ensure only one node instance is running; delete `data/chain.db` if corrupted.
**No blocks proposed:** Check proposer logs; ensure `PROPOSER_KEY` is set and no other proposers are conflicting.
**Mock coordinator not responding:** It's only needed for certain tests; the blockchain node can run standalone.
- **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.

**EXCHANGE INFRASTRUCTURE GAP IDENTIFIED** - While AITBC has achieved complete infrastructure standardization with 19+ services operational, a critical 40% gap exists between documented coin generation concepts and actual implementation. This milestone focuses on implementing missing exchange integration, oracle systems, and market infrastructure to complete the AITBC business model and enable full token economics ecosystem.
Comprehensive analysis reveals that core wallet operations (60% complete) are fully functional, but critical exchange integration components (40% missing) are essential for the complete AITBC business model. The platform requires immediate implementation of exchange commands, oracle systems, market making infrastructure, and advanced security features to achieve the documented vision.
Comprehensive analysis confirms core wallet operations are fully functional and exchange integration components are now in place. Focus shifts to sustaining reliability (exchange commands, oracle systems, market making) and hardening security to keep the ecosystem production-ready.
