A Python mining stack for the quip-protocol-rs Substrate chain. Drives CPU SA, GPU (CUDA / Metal / Modal), and QPU (D-Wave) miners against the chain's QuantumPow pallet — fetch the mining snapshot at each new chain head, search for valid Ising solutions, submit QuantumPow.submit_proof extrinsics, repeat.

This is the v0.2 line of the repository (formerly quip-protocol). In v0.1 this codebase shipped its own consensus, P2P (QUIC), block store, REST API, and SPHINCS+ block signer. v0.2 removes all of that — the chain is the source of truth, miners attach to it.

Component responsibilities (shared/):

Standalone scripts at repo root:

python3 -m venv .quip
source .quip/bin/activate
pip install -U pip setuptools wheel
pip install -e .

Dependencies pulled in by pyproject.toml:

• substrate-interface>=1.7.4, scalecodec>=1.2 — chain RPC + SCALE
• dwave-ocean-sdk>=9.0.0,<10, numpy>=1.24.0 — Ising sampling
• aiohttp>=3.9.0 — telemetry server + faucet
• click>=8.1.7 — CLI
• blake3>=1.0.5 — nonce derivation

D-Wave QPU access requires DWAVE_API_KEY in .env (loaded via python-dotenv).

In one terminal, bring up the chain:

cd ../quip-protocol-rs
docker compose up -d
docker compose logs -f node1   # confirm blocks being produced

The dev faucet now lives in its own repository (gitlab.com/quip.network/faucet); local-network setup (node + faucet + chain seeding) is handled by the testing repo at nodes.quip.network. Point the miner at a running faucet with --faucet-url; it self-funds and self-registers on first run.

Bootstrap a miner account (generates a keystore, funds it via the faucet, sudo-seeds Difficulty + DefaultTopology on a fresh chain, then submits register_miner):

quip-miner bootstrap \
    --node-url ws://localhost:9944 \
    --faucet-url http://127.0.0.1:8087 \
    --seed-chain

Run the miner:

quip-miner cpu \
    --node-url ws://localhost:9944 \
    --num-cpus 4 \
    --topology zephyr:9,2 \
    --rest-port 8086

In a third terminal, watch chain events for QuantumPow.ProofAccepted (via polkadot.js pointed at ws://localhost:9944), or hit the local telemetry API:

curl http://localhost:8086/api/v1/status   | jq
curl http://localhost:8086/api/v1/stats    | jq
curl http://localhost:8086/api/v1/system   | jq

Generate a fresh sr25519 signing key. Writes a 0o600 JSON keystore with the seed in plaintext (passphrase-encrypted keystores ship in Phase 7).

quip-miner keygen --out ~/.quip-miner/signing.json

Idempotent setup: generate keystore (if missing) → request funds from the faucet → submit register_miner. With --seed-chain, also sudo-submits set_difficulty + register_topology if missing.

quip-miner bootstrap \
    --node-url ws://localhost:9944 \
    --signer-key ~/.quip-miner/signing.json \
    --faucet-url http://127.0.0.1:8087 \
    --seed-chain \
    --seed-topology 9,2

Re-runs are no-ops that just verify state.

Run the mining controller. All three subcommands share these flags:

• --node-url ws://... (required) — substrate WS endpoint
• --signer-key ~/.quip-miner/signing.json — keystore path
• --topology zephyr:M,T — sampler topology (defaults to zephyr:9,2)
• --rest-port 8086 — HTTP telemetry port (-1 disables)

The cpu subcommand adds --num-cpus N; gpu adds --gpu-backend {local,metal,modal}; qpu adds --qpu-type and --daily-budget.

Topology binding is enforced at startup: the CLI hashes the configured topology with the same blake2_256(SCALE((sorted_nodes, canonical_edges))) recipe the chain uses, and refuses to start if the hash doesn't match the chain's registered topology.

GET  /api/v1/block/{n}/header              header subset
POST /api/v1/solve                         disabled in v0.2 (was direct DWave sample)

Response envelope: {"success": bool, "data": ..., "error": ..., "timestamp": int}.

The legacy /api/v1/peers, /api/v1/join, /api/v1/gossip, /api/v1/heartbeat, and POST /api/v1/block paths are removed — they were P2P / consensus surfaces with no equivalent in substrate mode. The legacy /telemetry/* SSE stream and per-peer aggregator also moved out; consumers should switch to substrate-side events and Prometheus (http://localhost:9615/metrics).

Mining works against any BoundedVec-bounded graph registered on chain (QuantumPow.RegisteredTopologies). The CLI's --topology zephyr:M,T constructs a dwave-networkx Zephyr graph; the chain's pallets/quantum-pow/src/topology.rs::hash_topology canonicalizes and blake2_256-hashes the result.

bootstrap --seed-chain --seed-topology 9,2 registers Zephyr Z(9,2) (1368 nodes / 7692 edges — the legacy default that matches the chain's difficulty calibration of max_energy_milli=-2_500_000). Smaller graphs (Z(2,2), Z(3,2)) work too but need their own difficulty calibration since their ground-state energy range is much narrower.

python -m pytest tests/ -v

Integration tests against the docker chain auto-skip if ws://localhost:9944 isn't reachable. The end-to-end controller test (test_controller_submits_proof_end_to_end) bootstraps inline and asserts at least one QuantumPow.ProofAccepted event lands within 120 seconds.

The cross-language nonce-parity test (test_derive_nonce_parity.py) reads crates/quantum-validation/tests/fixtures/python_parity.json from a sibling quip-protocol-rs checkout. Set QUIP_RUST_FIXTURE_DIR if your checkout is elsewhere.

Removed entirely:

• The local blockchain stack: shared/block.py, shared/node.py, shared/network_node.py, shared/block_store.py, shared/block_synchronizer.py, shared/block_requirements.py, genesis_block_public.json.
• The P2P stack: QUIC client/server, SWIM failure detector, peer scorer / ban list, gossip telemetry aggregator, sync wire codecs.
• The legacy signing path: SPHINCS+ block signer + certificate manager.
• CLI: quip-network-node and quip-network-simulator are gone. Use quip-miner instead.

Kept (with rewired backends):

• /api/v1/status, /system, /stats, /block/* (now substrate-backed)
• The 2-process worker model (MinerHandle ↔ child mp.Queue + stop_event)
• The Ising sampling code (BaseMiner.mine_work_item, quantum_proof_of_work.*, CPU/GPU/QPU subclasses)
• The hardware descriptor / aggregate stats (now exposed via MinerCore)

Migration:

• A v0.1 miner that ran a single mining node now runs a chain node (quip-protocol-rs docker compose) + quip-miner cpu|gpu|qpu against it.
• Mining rewards now accrue on chain to the registered sr25519 account, not as v0.1 block-proposer credit.
