# Hyperswarm + Hypercore

## Glue

Swarm for discovery, core.replicate over conn.

**Flow**:

```mermaid
graph LR
    Core[Hypercore] --> DiscKey[discoveryKey]
    Swarm.join(DiscKey)
    Swarm.connection --> Replicate[core.replicate(conn)]
```

**Ex**:

```js
swarm.on('connection', conn => {
  core.replicate(conn)
  blobs.replicate(conn) // Corestore multi
})
```

**Multi-Core**: Corestore.replicate(conn) handles all.

**Firewall**: Verify peer.pubKey before replicate.
