+# AITBC ZK Circuits
+
+Zero-knowledge circuits for privacy-preserving receipt attestation in the AITBC network.
+
+## Overview
+
+This project implements zk-SNARK circuits to enable privacy-preserving settlement flows while maintaining verifiability of receipts.
+
+## Quick Start
+
+### Prerequisites
+
+- Node.js 16+
+- npm or yarn
+
+### Installation
+
+```bash
+cd apps/zk-circuits
+npm install
+```
+
+### Compile Circuit
+
+```bash
+npm run compile
+```
+
+### Generate Trusted Setup
+
+```bash
+# Start phase 1 setup
+npm run setup
+
+# Contribute to setup (run multiple times with different participants)
+npm run contribute
+
+# Prepare phase 2
+npm run prepare
+
+# Generate proving key
+npm run generate-zkey
+
+# Contribute to zkey (optional)
+npm run contribute-zkey
+
+# Export verification key
+npm run export-verification-key
+```
+
+### Generate and Verify Proof
+
+```bash
+# Generate proof
+npm run generate-proof
+
+# Verify proof
+npm run verify
+
+# Run tests
+npm test
+```
+
+## Circuit Design
+
+### Current Implementation
+
+The initial circuit (`receipt.circom`) implements a simple hash preimage proof:
+
+- **Public Inputs**: Receipt hash
+- **Private Inputs**: Receipt data (job ID, miner ID, result, pricing)
+- **Proof**: Demonstrates knowledge of receipt data without revealing it
+
+### Future Enhancements
+
+1. **Full Receipt Attestation**: Complete validation of receipt structure
+2. **Signature Verification**: ECDSA signature validation
+3. **Arithmetic Validation**: Pricing and reward calculations
+4. **Range Proofs**: Confidential transaction amounts
+
+## Development
+
+### Circuit Structure
+
+```
+receipt.circom          # Main circuit file
+├── ReceiptHashPreimage # Simple hash preimage proof
+├── ReceiptAttestation  # Full receipt validation (WIP)
+└── ECDSAVerify        # Signature verification (WIP)
+```
+
+### Testing
+
+```bash
+# Run all tests
+npm test
+
+# Run specific test
+npx mocha test.js
+```
+
+### Integration
+
+The circuits integrate with:
+
+1. **Coordinator API**: Proof generation service
+2. **Settlement Layer**: On-chain verification contracts
+3. **Pool Hub**: Privacy options for miners
+
+## Security
+
+### Trusted Setup
+
+The Groth16 setup requires a trusted setup ceremony:
+
+1. Multi-party participation (>100 recommended)
+2. Public documentation
+3. Destruction of toxic waste
+
+### Audits
+
+- Circuit formal verification
+- Third-party security review
+- Public disclosure of circuits
+
+## Performance
+
+| Metric | Value |
+|--------|-------|
+| Proof Size | ~200 bytes |
+| Prover Time | 5-15 seconds |
+| Verifier Time | 3ms |
+| Gas Cost | ~200k |
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Circuit compilation fails**: Check circom version and syntax
+2. **Setup fails**: Ensure sufficient disk space and memory
+3. **Proof generation slow**: Consider using faster hardware or PLONK
+
+### Debug Commands
+
+```bash
+# Check circuit constraints
+circom receipt.circom --r1cs --inspect
+
+# View witness
+snarkjs wtns check witness.wtns receipt.wasm input.json
+
+# Debug proof generation
+DEBUG=snarkjs npm run generate-proof
+```

 # Coordinator API – Task Breakdown
 
-## Status (2025-09-27)
+## Status (2025-12-22)
 
 - **Stage 1 delivery**: Core FastAPI service, persistence, job lifecycle, and miner flows implemented under `apps/coordinator-api/`. Receipt signing now includes optional coordinator attestations with history retrieval endpoints.
 - **Testing & tooling**: Pytest suites cover job scheduling, miner flows, and receipt verification; the shared CI script `scripts/ci/run_python_tests.sh` executes these tests in GitHub Actions.
 - **Documentation**: `docs/run.md` and `apps/coordinator-api/README.md` describe configuration for `RECEIPT_SIGNING_KEY_HEX` and `RECEIPT_ATTESTATION_KEY_HEX` plus the receipt history API.
+- **Service APIs**: Implemented specific service endpoints for common GPU workloads (Whisper, Stable Diffusion, LLM inference, FFmpeg, Blender) with typed schemas and validation.
+- **Service Registry**: Created dynamic service registry framework supporting 30+ GPU services across 6 categories (AI/ML, Media Processing, Scientific Computing, Data Analytics, Gaming, Development Tools).
 
 ## Stage 1 (MVP)

   - Build `/v1/jobs` endpoints (submit, get status, get result, cancel) with idempotency support.
   - Build `/v1/miners` endpoints (register, heartbeat, poll, result, fail, drain).
   - Build `/v1/admin` endpoints (stats, job listing, miner listing) with admin auth.
+  - Build `/v1/services` endpoints for specific GPU workloads:
+    - `/v1/services/whisper/transcribe` - Audio transcription
+    - `/v1/services/stable-diffusion/generate` - Image generation
+    - `/v1/services/llm/inference` - Text generation
+    - `/v1/services/ffmpeg/transcode` - Video transcoding
+    - `/v1/services/blender/render` - 3D rendering
+  - Build `/v1/registry` endpoints for dynamic service management:
+    - `/v1/registry/services` - List all available services
+    - `/v1/registry/services/{id}` - Get service definition
+    - `/v1/registry/services/{id}/schema` - Get JSON schema
+    - `/v1/registry/services/{id}/requirements` - Get hardware requirements
   - Optionally add WebSocket endpoints under `ws/` for streaming updates.
 - **Receipts & Attestations**
   - ✅ Persist signed receipts (latest + history), expose `/v1/jobs/{job_id}/receipt(s)` endpoints, and attach optional coordinator attestations when `RECEIPT_ATTESTATION_KEY_HEX` is configured.

+
+# API Authentication
+
+All AITBC API endpoints require authentication using API keys.
+
+## Getting API Keys
+
+1. Visit the [AITBC Dashboard](https://dashboard.aitbc.io)
+2. Create an account or sign in
+3. Navigate to API Keys section
+4. Generate a new API key
+
+## Using API Keys
+
+### HTTP Header
+```http
+X-API-Key: your_api_key_here
+```
+
+### Environment Variable
+```bash
+export AITBC_API_KEY="your_api_key_here"
+```
+
+### SDK Configuration
+```python
+from aitbc import AITBCClient
+
+client = AITBCClient(api_key="your_api_key")
+```
+
+## Security Best Practices
+
+- Never commit API keys to version control
+- Use environment variables in production
+- Rotate keys regularly
+- Use different keys for different environments
+- Monitor API key usage
+
+## Rate Limits
+
+API requests are rate-limited based on your plan:
+- Free: 60 requests/minute
+- Pro: 600 requests/minute
+- Enterprise: 6000 requests/minute
+
+## Error Handling
+
+```python
+from aitbc.exceptions import AuthenticationError
+
+try:
+    client.jobs.create({...})
+except AuthenticationError:
+    print("Invalid API key")
+```
+
+## Key Management
+
+### View Your Keys
+```bash
+aitbc api-keys list
+```
+
+### Revoke a Key
+```bash
+aitbc api-keys revoke <key_id>
+```
+
+### Regenerate a Key
+```bash
+aitbc api-keys regenerate <key_id>

+title: Coordinator API Overview
+description: Introduction to the AITBC Coordinator API
+---
+
+# Coordinator API Overview
+
+The Coordinator API is the central service of the AITBC platform, responsible for job management, marketplace operations, and coordination between various components.
+
+## Base URL
+
+```
+Production: https://api.aitbc.io
+Staging: https://staging-api.aitbc.io
+Development: http://localhost:8011
+```
+
+## Authentication
+
+All API endpoints require authentication using an API key. Include the API key in the request header:
+
+```http
+X-API-Key: your_api_key_here
+```
+
+Get your API key from the [AITBC Dashboard](https://dashboard.aitbc.io).
+
+## Core Concepts
+
+### Jobs
+Jobs are the primary unit of work in AITBC. They represent AI computations that need to be executed.
+
+```json
+{
+  "job_id": "job_1234567890",
+  "type": "ai-inference",
+  "status": "running",
+  "created_at": "2024-01-01T12:00:00Z",
+  "estimated_completion": "2024-01-01T12:05:00Z"
+}
+```
+
+### Marketplace
+The marketplace connects job creators with miners who can execute the jobs.
+
+```json
+{
+  "offer_id": "offer_1234567890",
+  "job_type": "image-classification",
+  "price": "0.001",
+  "miner_id": "miner_1234567890"
+}
+```
+
+### Receipts
+Receipts provide cryptographic proof of job execution and results.
+
+```json
+{
+  "receipt_id": "receipt_1234567890",
+  "job_id": "job_1234567890",
+  "signature": {
+    "sig": "base64_signature",
+    "public_key": "base64_public_key"
+  }
+}
+```
+
+## Rate Limits
+
+API requests are rate-limited to ensure fair usage:
+
+| Plan | Requests per minute | Burst |
+|------|---------------------|-------|
+| Free | 60 | 10 |
+| Pro | 600 | 100 |
+| Enterprise | 6000 | 1000 |
+
+## Error Handling
+
+The API uses standard HTTP status codes and returns detailed error messages:
+
+```json
+{
+  "error": {
+    "code": "INVALID_API_KEY",
+    "message": "The provided API key is invalid",
+    "details": {
+      "request_id": "req_1234567890"
+    }
+  }
+}
+```
+
+Common error codes:
+- `400 Bad Request` - Invalid request parameters
+- `401 Unauthorized` - Invalid or missing API key
+- `403 Forbidden` - Insufficient permissions
+- `404 Not Found` - Resource not found
+- `429 Too Many Requests` - Rate limit exceeded
+- `500 Internal Server Error` - Server error
+
+## SDK Support
+
+Official SDKs are available for:
+- [Python](../../developer-guide/sdks/python.md)
+- [JavaScript/TypeScript](../../developer-guide/sdks/javascript.md)
+
+## WebSocket API
+
+Real-time updates are available through WebSocket connections:
+
+```javascript
+const ws = new WebSocket('wss://api.aitbc.io/ws');
+
+ws.onmessage = (event) => {
+  const data = JSON.parse(event.data);
+  console.log('Job update:', data);
+};
+```

+
+## Python Examples
+
+### Basic Job Submission
+```python
+from aitbc import AITBCClient
+
+client = AITBCClient(api_key="your_key")
+
+job = client.jobs.create({
+    "name": "image-classification",
+    "type": "ai-inference",
+    "model": {
+        "type": "python",
+        "entrypoint": "model.py",
+        "requirements": ["torch", "pillow"]
+    }
+})
+
+result = client.jobs.wait_for_completion(job["job_id"])
+```
+
+### Batch Job Processing
+```python
+import asyncio
+from aitbc import AsyncAITBCClient
+
+async def process_images(image_paths):
+    client = AsyncAITBCClient(api_key="your_key")
+    
+    tasks = []
+    for path in image_paths:
+        job = await client.jobs.create({
+            "name": f"process-{path}",
+            "type": "image-analysis"
+        })
+        tasks.append(client.jobs.wait_for_completion(job["job_id"]))
+    
+    results = await asyncio.gather(*tasks)
+    return results
+```
+
+## JavaScript Examples
+
+### React Component
+```jsx
+import React, { useState, useEffect } from 'react';
+import { AITBCClient } from '@aitbc/client';
+
+function JobList() {
+    const [jobs, setJobs] = useState([]);
+    const client = new AITBCClient({ apiKey: 'your_key' });
+    
+    useEffect(() => {
+        async function fetchJobs() {
+            const jobList = await client.jobs.list();
+            setJobs(jobList);
+        }
+        fetchJobs();
+    }, []);
+    
+    return (
+        <div>
+            {jobs.map(job => (
+                <div key={job.jobId}>
+                    <h3>{job.name}</h3>
+                    <p>Status: {job.status}</p>
+                </div>
+            ))}
+        </div>
+    );
+}
+```
+
+### WebSocket Integration
+```javascript
+const client = new AITBCClient({ apiKey: 'your_key' });
+const ws = client.websocket.connect();
+
+ws.on('jobUpdate', (data) => {
+    console.log(`Job ${data.jobId} updated to ${data.status}`);
+});
+
+ws.subscribe('jobs');
+ws.start();
+```
+
+## CLI Examples
+
+### Job Management
+```bash
+# Create job from file
+aitbc job create job.yaml
+
+# List all jobs
+aitbc job list --status running
+
+# Monitor job progress
+aitbc job watch <job_id>
+
+# Download results
+aitbc job download <job_id> --output ./results/
+```
+
+### Marketplace Operations
+```bash
+# List available offers
+aitbc marketplace list --type image-classification
+
+# Create offer as miner
+aitbc marketplace create-offer offer.yaml

+# Custom event handlers
+ws = client.websocket.connect()
+
+@ws.on_job_update
+def on_job_update(job_id, status):
+    print(f"Job {job_id} status: {status}")
+
+@ws.on_marketplace_update
+def on_marketplace_update(update_type, data):
+    print(f"Marketplace {update_type}: {data}")
+
+# Run with context manager
+with client.websocket.connect() as ws:
+    ws.subscribe("jobs")
+    ws.listen(timeout=60)
+```
+
+## Error Handling
+
+```python
+from aitbc.exceptions import (
+    AITBCError,
+    APIError,
+    AuthenticationError,
+    NotFoundError,
+    RateLimitError
+)
+
+try:
+    job = client.jobs.create({...})
+except AuthenticationError:
+    print("Invalid API key")
+except RateLimitError as e:
+    print(f"Rate limited. Retry in {e.retry_after} seconds")
+except APIError as e:
+    print(f"API error: {e.message}")
+except AITBCError as e:
+    print(f"AITBC error: {e}")
+```
+
+## Advanced Usage
+
+### Custom HTTP Client
+
+```python
+import requests
+from aitbc import AITBCClient
+
+# Use custom session
+session = requests.Session()
+session.headers.update({"User-Agent": "MyApp/1.0"})
+
+client = AITBCClient(
+    api_key="your_key",
+    session=session
+)
+```
+
+### Async Support
+
+```python
+import asyncio
+from aitbc import AsyncAITBCClient
+
+async def main():
+    client = AsyncAITBCClient(api_key="your_key")
+    
+    # Create job
+    job = await client.jobs.create({...})
+    
+    # Wait for completion
+    result = await client.jobs.wait_for_completion(job["job_id"])
+    
+    print(f"Result: {result}")
+
+asyncio.run(main())
+```
+
+### Batch Operations
+
+```python
+# Create multiple jobs
+jobs = [
+    {"name": f"job-{i}", "type": "ai-inference"}
+    for i in range(10)
+]
+
+created_jobs = client.jobs.create_batch(jobs)
+
+# Get status of multiple jobs
+statuses = client.jobs.get_status_batch([
+    job["job_id"] for job in created_jobs
+])
+```
+
+## Testing
+
+### Mock Client for Testing
+
+```python
+from aitbc.testing import MockAITBCClient
+
+# Use mock client for tests
+client = MockAITBCClient()
+
+# Configure responses
+client.jobs.set_response("create", {"job_id": "test_job"})
+
+# Test your code
+job = client.jobs.create({...})
+assert job["job_id"] == "test_job"
+```
+
+### Integration Tests
+
+```python
+import pytest
+from aitbc import AITBCClient
+
+@pytest.fixture
+def client():
+    return AITBCClient(
+        api_key="test_key",
+        base_url="http://localhost:8011"
+    )
+
+def test_job_creation(client):
+    job = client.jobs.create({
+        "name": "test-job",
+        "type": "ai-inference"
+    })
+    assert "job_id" in job
+```
+
+## Best Practices
+
+### 1. Configuration Management
+```python
+# Use environment variables
+import os
+from aitbc import AITBCClient
+
+client = AITBCClient(
+    api_key=os.getenv("AITBC_API_KEY"),
+    base_url=os.getenv("AITBC_BASE_URL", "https://api.aitbc.io")
+)
+```
+
+### 2. Error Handling
+```python
+# Always handle potential errors
+try:
+    result = client.jobs.get_results(job_id)
+except NotFoundError:
+    print("Job not found")
+except APIError as e:
+    print(f"API error: {e}")
+```
+
+### 3. Resource Management
+```python
+# Use context managers for resources
+with client.jobs.upload_context(job_id) as ctx:
+    ctx.upload_file("model.py")
+    ctx.upload_file("requirements.txt")
+```
+
+### 4. Performance
+```python
+# Use async for concurrent operations
+async def process_jobs(job_ids):
+    client = AsyncAITBCClient(api_key="your_key")
+    
+    tasks = [
+        client.jobs.get_results(job_id)
+        for job_id in job_ids
+    ]
+    
+    results = await asyncio.gather(*tasks)
+    return results
+```

+# AITBC Request for Comments (RFC) Process
+
+## Overview
+
+The RFC (Request for Comments) process is the primary mechanism for proposing and discussing major changes to the AITBC protocol, ecosystem, and governance. This process ensures transparency, community involvement, and thorough technical review before significant changes are implemented.
+
+## Process Stages
+
+### 1. Idea Discussion (Pre-RFC)
+- Open issue on GitHub with `idea:` prefix
+- Community discussion in GitHub issue
+- No formal process required
+- Purpose: Gauge interest and gather early feedback
+
+### 2. RFC Draft
+- Create RFC document using template
+- Submit Pull Request to `rfcs` repository
+- PR labeled `rfc-draft`
+- Community review period: 2 weeks minimum
+
+### 3. RFC Review
+- Core team assigns reviewers
+- Technical review by subject matter experts
+- Community feedback incorporated
+- PR labeled `rfc-review`
+
+### 4. Final Comment Period (FCP)
+- RFC marked as `final-comment-period`
+- 10 day waiting period for final objections
+- All substantive objections must be addressed
+- PR labeled `fcp`
+
+### 5. Acceptance or Rejection
+- After FCP, RFC is either:
+  - **Accepted**: Implementation begins
+  - **Rejected**: Document archived with reasoning
+  - **Deferred**: Returned to draft for revisions
+
+### 6. Implementation
+- Accepted RFCs enter implementation queue
+- Implementation tracked in project board
+- Progress updates in RFC comments
+- Completion marked in RFC status
+
+## RFC Categories
