Node Status & Blueprint Alignment

Snapshot of the current quantum_node.py implementation and next steps for Stage 1.

Current Implementation

Stage 1 · ~80% Complete

Single-node PoC

Endpoints POST /api/account, POST /api/mine, POST /api/data, GET /api/chain, GET /api/status
Storage blockchain.json and balances.json stored in the script directory.
Quantum Uses Qiskit qasm_simulator if available, otherwise falls back to os.urandom.
Network Host: 0.0.0.0, Port: 5000 (hard-coded).
Mining Fixed mining reward: 5 coins per block (hard-coded).

Next active task: implement atomic writes for chain and balances, then add startup integrity checks, structured logging, and config.json.

To Finish Single-node PoC

• Atomic writes for blockchain.json and balances.json (write to temp file, then rename).
• On startup, run integrity check: recompute hashes for all blocks, verify chain continuity.
• Add logging for node start, new block creation, quantum failures, invalid requests.
• Move hard-coded values (host, port, data dir, mining reward, quantum mode) into config.json or environment variables.

Quick sanity check

# From Termux (phone)
curl http://127.0.0.1:5000/api/status

Once atomic writes & integrity checks are in place and /api/status reflects the latest height reliably, Stage 1 can be marked as complete.
