Service Run Instructions

These instructions cover the newly scaffolded services. Install dependencies using Poetry (preferred) or pip inside a virtual environment.

Prerequisites

• Python 3.11+
• Poetry 1.7+ (or virtualenv + pip)
• Optional: GPU drivers for miner node workloads

Coordinator API (apps/coordinator-api/)

1. Navigate to the service directory:

   cd apps/coordinator-api
   

2. Install dependencies:

3. Copy environment template and adjust values:

   cp .env.example .env
   

   Add coordinator API keys and, if you want signed receipts, set RECEIPT_SIGNING_KEY_HEX to a 64-byte Ed25519 private key encoded in hex.

4. Configure database (shared Postgres): ensure .env contains DATABASE_URL=postgresql://aitbc:248218d8b7657aef@localhost:5432/aitbc or export it in the shell before running commands.

5. Run the API locally (development):

   poetry run uvicorn app.main:app --host 0.0.0.0 --port 8011 --reload
   

6. Production-style launch using Gunicorn (ports start at 8900):

   poetry run gunicorn app.main:app -k uvicorn.workers.UvicornWorker -b 0.0.0.0:8900
   

7. Generate a signing key (optional):

   python - <<'PY'
   from nacl.signing import SigningKey
   sk = SigningKey.generate()
   print(sk.encode().hex())
   PY
   

   Store the printed hex string in RECEIPT_SIGNING_KEY_HEX to enable signed receipts in responses. To add coordinator attestations, set RECEIPT_ATTESTATION_KEY_HEX to a separate Ed25519 private key; responses include an attestations array that can be verified with the corresponding public key.

8. Retrieve receipts:

   • Latest receipt for a job: GET /v1/jobs/{job_id}/receipt
   • Entire receipt history: GET /v1/jobs/{job_id}/receipts

   Ensure the client request includes the appropriate API key; responses embed signed payloads compatible with packages/py/aitbc-crypto verification helpers. Example verification snippet using the Python helpers:

   export PYTHONPATH=packages/py/aitbc-crypto/src
   python - <<'PY'
   from aitbc_crypto.signing import ReceiptVerifier
   from aitbc_crypto.receipt import canonical_json
   import json
   
   receipt = json.load(open("receipt.json", "r"))
   verifier = ReceiptVerifier(receipt["signature"]["public_key"])
   verifier.verify(receipt)
   print("receipt verified", receipt["receipt_id"])
   PY
   

   Alternatively, install the Python SDK helpers:

   cd packages/py/aitbc-sdk
   poetry install
   export PYTHONPATH=packages/py/aitbc-sdk/src:packages/py/aitbc-crypto/src
   python - <<'PY'
   from aitbc_sdk import CoordinatorReceiptClient, verify_receipt
   
   client = CoordinatorReceiptClient("http://localhost:8011", "client_dev_key_1")
   receipt = client.fetch_latest("<job_id>")
   verification = verify_receipt(receipt)
   print("miner signature valid:", verification.miner_signature.valid)
   print("coordinator attestations:", [att.valid for att in verification.coordinator_attestations])
   PY
   For receipts containing `attestations`, iterate the list and verify each entry with the corresponding public key.
   A JavaScript helper will ship with the Stage 2 SDK under `packages/js/`; until then, receipts can be verified with Node.js by loading the canonical JSON and invoking an Ed25519 verify function from `tweetnacl` (the payload is `canonical_json(receipt)` and the public key is `receipt.signature.public_key`).
   Example Node.js snippet:
   ```bash
   node <<'JS'
   

import fs from "fs"; import nacl from "tweetnacl"; import canonical from "json-canonicalize";

const receipt = JSON.parse(fs.readFileSync("receipt.json", "utf-8")); const message = canonical(receipt).trim(); const sig = receipt.signature.sig; const key = receipt.signature.key_id;

const signature = Buffer.from(sig.replace(/-/g, "+").replace(//g, "/"), "base64"); const publicKey = Buffer.from(key.replace(/-/g, "+").replace(//g, "/"), "base64");

const ok = nacl.sign.detached.verify(Buffer.from(message, "utf-8"), signature, publicKey); console.log("verified:", ok); JS

## Solidity Token (`packages/solidity/aitbc-token/`)

1. Navigate to the token project:
 ```bash
 cd packages/solidity/aitbc-token
 npm install

2. Run the contract unit tests:

   npx hardhat test
   

3. Deploy AIToken to the configured Hardhat network. Provide the coordinator (required) and attestor (optional) role recipients via environment variables:

   COORDINATOR_ADDRESS=0xCoordinator \
   ATTESTOR_ADDRESS=0xAttestor \
   npx hardhat run scripts/deploy.ts --network localhost
   

   The script prints the deployed address and automatically grants the coordinator and attestor roles if they are not already assigned. Export the printed address for follow-on steps:

   export AITOKEN_ADDRESS=0xDeployedAddress
   

4. Mint tokens against an attested receipt by calling the contract from Hardhat’s console or a script. The helper below loads the deployed contract and invokes mintWithReceipt with an attestor signature:

   // scripts/mintWithReceipt.ts
   import { ethers } from "hardhat";
   import { AIToken__factory } from "../typechain-types";
   
   async function main() {
     const [coordinator] = await ethers.getSigners();
     const token = AIToken__factory.connect(process.env.AITOKEN_ADDRESS!, coordinator);
   
     const provider = "0xProvider";
     const units = 100n;
     const receiptHash = "0x...";
     const signature = "0xSignedStructHash";
   
     const tx = await token.mintWithReceipt(provider, units, receiptHash, signature);
     await tx.wait();
     console.log("Mint complete", await token.balanceOf(provider));
   }
   
   main().catch((err) => {
     console.error(err);
     process.exitCode = 1;
   });
   

   Execute the helper with AITOKEN_ADDRESS exported and the signature produced by the attestor key used in your tests or integration flow:

   AITOKEN_ADDRESS=$AITOKEN_ADDRESS npx ts-node scripts/mintWithReceipt.ts
   

5. To derive the signature payload, reuse the buildSignature helper from test/aitoken.test.ts or recreate it in a script. The struct hash encodes (chainId, contractAddress, provider, units, receiptHash) and must be signed by an authorized attestor account.

Wallet Daemon (apps/wallet-daemon/)

1. Navigate to the service directory:

2. Install dependencies:

   poetry install
   

3. Copy or create .env with coordinator access:

   cp .env.example .env  # create if missing
   

   Populate COORDINATOR_BASE_URL and COORDINATOR_API_KEY to reuse the coordinator API when verifying receipts.
4. Run the API locally:

   poetry run uvicorn app.main:app --host 0.0.0.0 --port 8071 --reload
   

5. REST endpoints:
   • GET /v1/receipts/{job_id} – fetch + verify latest coordinator receipt.
   • GET /v1/receipts/{job_id}/history – fetch + verify entire receipt history.
6. JSON-RPC endpoint:
   • POST /rpc with methods receipts.verify_latest and receipts.verify_history returning signature validation metadata identical to REST responses.
7. Example REST usage:

   curl -s "http://localhost:8071/v1/receipts/<job_id>" | jq
   

8. Example JSON-RPC call:

   curl -s http://localhost:8071/rpc \
     -H 'Content-Type: application/json' \
     -d '{"jsonrpc":"2.0","id":1,"method":"receipts.verify_latest","params":{"job_id":"<job_id>"}}' | jq
   

9. Keystore scaffold:
   • KeystoreService currently stores wallets in-memory using Argon2id key derivation + XChaCha20-Poly1305 encryption.
   • Subsequent milestones will back this with persistence and CLI/REST routes for wallet creation/import.

Miner Node (apps/miner-node/)

1. Navigate to the directory:

   cd apps/miner-node
   

2. Install dependencies:

   poetry install
   

3. Configure environment:

   cp .env.example .env
   

   Adjust COORDINATOR_BASE_URL, MINER_AUTH_TOKEN, and workspace paths.
4. Run the miner control loop:

   poetry run python -m aitbc_miner.main
   

   The miner now registers and heartbeats against the coordinator, polling for work and executing CLI/Python runners. Ensure the coordinator service is running first.
5. Deploy as a systemd service (optional):

   sudo scripts/ops/install_miner_systemd.sh
   

   Add or update /opt/aitbc/apps/miner-node/.env, then use sudo systemctl status aitbc-miner to monitor the service.

Blockchain Node (apps/blockchain-node/)

1. Navigate to the directory:

   cd apps/blockchain-node
   

2. Install dependencies:

   poetry install
   

3. Configure environment:

   cp .env.example .env
   

   Update database path, proposer key, and bind host/port as needed.
4. Run the node placeholder:

   poetry run python -m aitbc_chain.main
   

   (RPC, consensus, and P2P logic still to be implemented.)

Next Steps

• Flesh out remaining logic per task breakdowns in docs/*.md (e.g., capability-aware scheduling, artifact uploads).
• Run the growing test suites regularly:
  • pytest apps/coordinator-api/tests/test_jobs.py
  • pytest apps/coordinator-api/tests/test_miner_service.py
  • pytest apps/miner-node/tests/test_runners.py
• Create systemd and Nginx configs once services are runnable in production mode.
