# Art DAG L2 Server - ActivityPub
Ownership registry and ActivityPub federation for Art DAG.
Ownership registry and ActivityPub federation for Art DAG. Manages asset provenance, cryptographic anchoring, and distributed identity.
## What it does
## Features
- **Registry**: Maintains owned assets with content hashes
- **Activities**: Creates signed ownership claims (Create activities)
- **Federation**: ActivityPub endpoints for follow/share
- **L1 Integration**: Records completed L1 runs as owned assets
- **Authentication**: User registration, login, JWT tokens
- **Asset Registry**: Content-addressed assets with provenance tracking
- **ActivityPub Federation**: Standard protocol for distributed social networking
- **OpenTimestamps Anchoring**: Cryptographic proof of existence on Bitcoin blockchain
- **L1 Integration**: Record and verify L1 rendering runs
- **Storage Providers**: S3, IPFS, and local storage backends
- **Scoped Authentication**: Secure token-based auth for federated L1 servers
## Setup
## Dependencies
- **PostgreSQL**: Primary data storage
- **artdag-common**: Shared templates and middleware
- **cryptography**: RSA key generation and signing
- **httpx**: Async HTTP client for federation
## Quick Start
```bash
# Install dependencies
pip install -r requirements.txt
# Configure (optional - defaults shown)
export ARTDAG_DOMAIN=artdag.rose-ash.com
# Configure
export ARTDAG_DOMAIN=artdag.example.com

## JWT Secret Configuration
The JWT secret is used to sign authentication tokens. **Without a persistent secret, tokens are invalidated on server restart.**
### Generate a secret
## Docker Deployment
```bash
# Generate a 64-character hex secret
docker stack deploy -c docker-compose.yml artdag-l2
```
## Configuration
### Environment Variables
| Variable | Default | Description |
|----------|---------|-------------|
| `ARTDAG_DOMAIN` | `artdag.rose-ash.com` | Domain for ActivityPub actors |
| `ARTDAG_USER` | `giles` | Default username |
| `ARTDAG_DATA` | `~/.artdag/l2` | Data directory |
| `DATABASE_URL` | `postgresql://artdag:artdag@localhost:5432/artdag` | PostgreSQL connection |
| `L1_SERVERS` | - | Comma-separated list of L1 server URLs |
| `JWT_SECRET` | (generated) | JWT signing secret |
| `HOST` | `0.0.0.0` | Server bind address |
| `PORT` | `8200` | Server port |
### JWT Secret
The JWT secret signs authentication tokens. Without a persistent secret, tokens are invalidated on restart.
```bash
# Generate a secret
openssl rand -hex 32
# Or with Python
python -c "import secrets; print(secrets.token_hex(32))"
# Set in environment
export JWT_SECRET="your-generated-secret"
# Or use Docker secrets (recommended for production)
echo "your-secret" | docker secret create jwt_secret -
```
### Local development
### RSA Keys
ActivityPub requires RSA keys for signing activities:
```bash
export JWT_SECRET="your-generated-secret-here"
python server.py
```
### Docker Swarm (recommended for production)
Create a Docker secret:
```bash
# From a generated value
openssl rand -hex 32 | docker secret create jwt_secret -
# Or from a file
echo "your-secret-here" > jwt_secret.txt
docker secret create jwt_secret jwt_secret.txt
rm jwt_secret.txt
```
Reference in docker-compose.yml:
```yaml
services:
l2-server:
secrets:
- jwt_secret
secrets:
jwt_secret:
external: true
```
The server reads secrets from `/run/secrets/jwt_secret` automatically.
## Key Setup
ActivityPub requires RSA keys for signing activities. Generate them:
```bash
# Local
# Generate keys
python setup_keys.py
# Or with custom paths
python setup_keys.py --data-dir /data/l2 --user giles
# In Docker, exec into container or mount volume
docker exec -it <container> python setup_keys.py
```
Keys are stored in `$ARTDAG_DATA/keys/`:
- `{username}.pem` - Private key (chmod 600, NEVER share)
- `{username}.pub` - Public key (included in actor profile)
**Important**: Private keys are gitignored. Back them up securely. Losing them invalidates all your signatures.
## L1 Renderers Configuration
The `L1_SERVERS` environment variable defines which L1 rendering servers are available to users. Users can attach to these servers from the Renderers page to run effects and manage media.
```bash
# Single server (default)
export L1_SERVERS=https://celery-artdag.rose-ash.com
# Multiple servers (comma-separated)
export L1_SERVERS=https://celery-artdag.rose-ash.com,https://renderer2.example.com,https://renderer3.example.com
```
When a user attaches to an L1 server:
1. L2 creates a **scoped token** that only works for that specific L1
2. User is redirected to the L1's `/auth` endpoint with the scoped token
3. L1 calls back to L2's `/auth/verify` endpoint to validate the token
4. L2 verifies the token scope matches the requesting L1
5. L1 sets its own local cookie, logging the user in
6. The attachment is recorded in L2's `user_renderers` table
### Security Features
**No shared secrets**: L1 servers verify tokens by calling L2's `/auth/verify` endpoint. Any L1 provider can federate without the JWT secret.
**L1 authorization**: Only servers listed in `L1_SERVERS` can verify tokens. L1 must identify itself in verify requests.
**Scoped tokens**: Tokens issued for attachment contain an `l1_server` claim. A token scoped to L1-A cannot be used on L1-B, preventing malicious L1s from stealing tokens for use elsewhere.
**Federated logout**: When a user logs out of L2:
1. L2 revokes the token in its database (`revoked_tokens` table)
2. L2 calls `/auth/revoke` on all attached L1s to revoke their local copies
3. All attachments are removed from `user_renderers`
Even if a malicious L1 ignores the revoke call, the token will fail verification at L2 because it's in the revocation table.
**Token revocation on L1**: L1 servers maintain their own Redis-based revocation list and check it on every authenticated request.
Users can manage attachments at `/renderers`.
Keys stored in `$ARTDAG_DATA/keys/`:
- `{username}.pem` - Private key (chmod 600)
- `{username}.pub` - Public key (in actor profile)
## Web UI

## L1 Renderer Integration
L2 coordinates with L1 rendering servers for distributed processing.
### Configuration
```bash
curl -X POST http://localhost:8200/assets \
-H "Content-Type: application/json" \
# Single L1 server
export L1_SERVERS=https://celery-artdag.rose-ash.com
# Multiple L1 servers
export L1_SERVERS=https://server1.example.com,https://server2.example.com
```
### Attachment Flow
1. User visits `/renderers` and clicks "Attach"
2. L2 creates a **scoped token** bound to the specific L1
3. User redirected to L1's `/auth?auth_token=...`
4. L1 calls L2's `/auth/verify` to validate
5. L2 checks token scope matches requesting L1
6. L1 sets local cookie, attachment recorded in `user_renderers`
### Security
- **Scoped tokens**: Tokens bound to specific L1; can't be used elsewhere
- **No shared secrets**: L1 verifies via L2's `/auth/verify` endpoint
- **Federated logout**: L2 revokes tokens on all attached L1s
## OpenTimestamps Anchoring
Cryptographic proof of existence using Bitcoin blockchain.
### How It Works
1. Activities are collected into merkle trees
2. Merkle root submitted to Bitcoin via OpenTimestamps
3. Pending proofs upgraded when Bitcoin confirms
4. Final proof verifiable without trusted third parties
### Verification
```bash
# Verify an activity's timestamp
curl https://artdag.example.com/anchors/verify/123
# Returns:
{
"activity_id": 123,
"merkle_root": "abc123...",
"status": "confirmed",
"bitcoin_block": 800000,
"verified_at": "2026-01-01T..."
}
```
