You can change the pubsub `emitSelf` option if you don't want the publishing node to receive its own messages.

```JavaScript
const defaults = {
config: {
pubsub: {
enabled: true,
emitSelf: false

}
}

## 2. Future work

libp2p/IPFS PubSub is enabling a whole set of Distributed Real Time applications using CRDT (Conflict-Free Replicated Data Types). It is still going through heavy research (and hacking) and we invite you to join the conversation at [research-CRDT](https://github.com/ipfs/research-CRDT). Here is a list of some of the exciting examples:
