PeerManager will emit the following events: 'version', 'verack', 'addr', 'getaddr', 'error' 'disconnect'; and will relay events like: 'tx', 'block', 'inv'. Please see [PeerManager.js ](PeerManager.js ), [Peer.js ](Peer.js ) and [Connection.js ](Connection.js )
## Consuming bitcoind RPC
For this example you need a running bitcoind instance with RPC enabled.
```js

if (err) {
