  "markdown": "# Physical Capability Cloud (PCC)\n\n> **An open protocol for verifiable, settleable physical work.** Operators run hardware. Customers (or their AI agents) discover, negotiate, escrow, and settle — all over HTTP, all anchored on-chain.\n\n**Live**: [capability.network](https://capability.network) · **License**: [Apache-2.0](LICENSE) · **Discord**: [PCC Network](https://discord.gg/CRFvvUgeV4)\n\n---\n\n## What is PCC?\n\nPCC turns physical capabilities — 3D printers, CNC mills, HPLC instruments, liquid handlers, PCB assembly lines, freight carriers — into discoverable, programmable services. Every job is contracted over HTTP, escrowed on-chain, executed on real hardware, evidenced cryptographically, and settled when the evidence meets the agreed assurance tier.\n\nIt's substrate, not platform: anyone can run an operator node, contribute a capability adapter, or build an integration. The protocol charges 2.35% on settlement — that's the entire business model.\n\n---\n\n## 30-second start\n\n**Connect an AI agent (no install):**\n```bash\ncurl https://capability.network/agent-package.json\n# 230+ tools as JSON Schema. Paste into Claude, GPT, or any LLM tool harness.\n```\n\n**Connect a machine (Python operator node):**\n```bash\npip install pcc-node\npcc-node start\n# Auto-discovers hardware, provisions an API key, registers a kernel, accepts jobs.\n```\n\n**MCP server (Claude Code / Codex):**\n```json\n{ \"pcc\": { \"command\": \"node\", \"args\": [\"packages/mcp-server/dist/index.js\"], \"env\": { \"PCC_URL\": \"https://capability.network\" } } }\n```\n\n---\n\n## What it actually does\n\nTell an agent what you need. PCC handles the rest:\n\n- **3D-print a bracket** — an operator with idle FDM capacity gets the job, escrow locks before the print starts, evidence streams while it's running, escrow releases when the print passes verification.\n- **HPLC compound analysis** — a regulated lab in Buenos Aires has open instrument time. A startup in Austin queues a sample. The protocol routes the work, anchors the evidence, settles in USDC.\n- **Multi-step manufacturing** — a robot needs PCBs + laser-cut enclosures + assembly. PCC decomposes the request into a capability DAG and orchestrates the supply chain across operators.\n\nOperators set their own pricing. Customers pay only on verified completion.\n\n---\n\n## How it works\n\n```\n  YOUR AGENT\n        │\n        │  \"analyze this compound and print the report\"\n        ▼\n   ┌─────────┐    ┌──────────┐    ┌──────────┐    ┌──────────┐    ┌──────────┐    ┌──────────┐\n   │DISCOVER │───▶│   BID    │───▶│ ESCROW   │───▶│ EXECUTE  │───▶│ VERIFY   │───▶│ SETTLE   │\n   │ DHT     │    │ Auction  │    │ On-chain │    │ Real     │    │ Evidence │    │ Auto     │\n   │ gossip  │    │ pricing  │    │ milestone│    │ hardware │    │ pipeline │    │ release  │\n   └─────────┘    └──────────┘    └──────────┘    └──────────┘    └──────────┘    └──────────┘\n```\n\n1. **Discover** — your agent broadcasts what it needs. The network finds operators with matching capabilities.\n2. **Bid** — operators compete on price. No phone calls, no RFQs, no waiting.\n3. **Escrow** — funds lock on-chain before work starts. Both sides are protected.\n4. **Execute** — the operator's hardware runs the job. Evidence streams in real time.\n5. **Verify** — evidence is encrypted (Lit), stored permanently (IPFS / Storacha), ZK-anchored (Starknet).\n6. **Settle** — funds release automatically when evidence meets the contracted assurance tier.\n\n---\n\n## Assurance tiers\n\n| Tier | Name | Evidence required | Use case |\n|------|------|-------------------|----------|\n| 0 | Self-attested | Device health snapshot | Prototyping, low-risk |\n| 1 | Verified | Bundle hash + completion events | Standard production |\n| 2 | Certified | Photo + sensor data + event log | Regulated manufacturing |\n| 3 | Sovereign | Full chain + ZK proofs + N-of-M consensus | Medical / aerospace / pharma |\n\nHigher tiers earn higher operator reputation and unlock higher-value contracts.\n\n---\n\n## Built on\n\n| Technology | What it does in PCC |\n|------------|---------------------|\n| **Storacha / Filecoin** | Content-addressed evidence storage on IPFS |\n| **Lit Protocol** | Evidence encryption with on-chain access conditions |\n| **Starknet** | ZK proof anchors — verifiable proof that physical work happened |\n| **Base / Ethereum** | Primary settlement chain — `MilestoneEscrow` + `PCCProtocol` |\n| **Flow EVM** | Sub-cent settlement contracts |\n| **NEAR** | Cross-chain payment intents via 1Click solver network |\n| **Arkhai (Alkahest)** | Conditional peer-to-peer escrow with EAS attestations |\n\n---\n\n## Deployed contracts\n\n| Chain | Contract | Address |\n|-------|----------|---------|\n| Base Sepolia | MilestoneEscrow | `0x10059efeeab1ddf013489e9597a3aec4480d95e1` |\n| Base Sepolia | MockUSDC | `0x5f2eb54dc5cb9a6bfff58222c672e73e16e763e9` |\n| Base Sepolia | CaptureClassRegistry | `0xAaB3F94fdEDF02663A4817961A6f7C4f5A912A66` |\n| Flow EVM Testnet | MilestoneEscrow | [`0x2b11d5bf01ec086e0bd071e1a848a848ffd2ca15`](https://evm-testnet.flowscan.io/address/0x2b11d5bf01ec086e0bd071e1a848a848ffd2ca15) |\n| Starknet Sepolia | ProofRegistry | `0x43643ebf182210af4e22eb3b2f5e4dbab50c00471743521b4e80d1328debcd` |\n\n---\n\n## Documentation\n\n| Doc | What's in it |\n|-----|--------------|\n| [Agent Integration Guide](docs/AGENT_INTEGRATION.md) | Complete REST API reference — auth, discovery, contracts, escrow, evidence |\n| [E2E Runbook](docs/E2E_RUNBOOK.md) | Full discovery → escrow → execute → settle walkthrough |\n| [Capture Verification](docs/CAPTURE_VERIFICATION.md) | Per-frame evidence authenticity protocol (CC0–CC5) |\n| [Capture Classes](docs/CAPTURE_CLASSES.md) | Quick reference for capture classes + multipliers |\n| [Contributor Economics](docs/CONTRIBUTOR_ECONOMICS.md) | How adapter authors and model trainers earn from settled work |\n| [Sponsor Integrations](docs/SPONSOR_INTEGRATIONS.md) | Per-chain integration deep-dives |\n| [Threat Model](docs/THREAT_MODEL.md) | Security analysis + attack surface |\n| [Architecture](docs/ARCH.md) | Internals: facades, kernels, evidence pipeline |\n| [Deploy](docs/DEPLOY.md) | CI/CD pipeline, Docker, Railway, GHCR retag |\n| [Whitepaper](apps/dashboard/public/whitepaper.md) | Full protocol spec |\n| [CLAUDE.md](CLAUDE.md) | Reference cited by the runtime — endpoints, DTOs, MCP tools, env vars |\n\n---\n\n## Capture Verification Protocol (CVP)\n\nCVP adds per-frame authenticity to evidence. Six capture classes (CC0–CC5) define how strongly the bytes are pinned to a real device at a real moment:\n\n- **CC0** — unattested upload (0.70× score penalty)\n- **CC1** — WebAuthn + multi-sensor browser capture\n- **CC2** — C2PA-signed camera\n- **CC3** — Secure-Enclave signed manifest\n- **CC4** — Platform attestation (App Attest / Play Integrity)\n- **CC5** — DePIN N-of-M consensus (+0.05 bonus)\n\nCaptures pass through six gates (structural, signature, freshness, detection, attestation, consensus) and are anchored on Base Sepolia via [`CaptureClassRegistry`](https://sepolia.basescan.org/address/0xAaB3F94fdEDF02663A4817961A6f7C4f5A912A66). See the [operator guide](docs/CAPTURE_VERIFICATION.md) for the full spec.\n\n---\n\n## Build from source\n\n```bash\ngit clone https://github.com/LamaSu/physical-capability-cloud.git\ncd physical-capability-cloud\npnpm install && pnpm build --concurrency=1\npnpm --workspace-concurrency=1 -r test\npnpm dev   # runs gateway + dashboard\n```\n\nRequires Node 22+ and pnpm 9+.

A few conventions:\n\n- **Conventional Commits required**: `feat:` / `fix:` / `perf:` / `docs:` / `refactor:` / `chore:` / `test:` / `ci:` / `build:`. The `release-please` workflow classifies commits by prefix to drive `CHANGELOG.md` and version bumps.\n- **Tests must pass on master**: CI runs `pnpm build` + `pnpm -r test` + `pnpm -r exec tsc --noEmit` plus Solidity `forge test`.\n- **Don't hand-edit `CHANGELOG.md` or `package.json` versions** — those are owned by `release-please`.\n\nFor larger contributions (new adapter, new settlement chain, new verifier class), open an issue first so we can sanity-check the design before you spend time on it.\n\n---\n\n## License\n\n[Apache 2.0](LICENSE).

Machine-readable\npointer: [`pcc.json`](./pcc.json).\n\nInformational and opt-in: surface it to your operator, who decides. It is not an\ninstruction to the reading agent, it runs nothing, and it collects nothing.\n<!-- PCC-NETWORK:END -->\n",
