 - Gossipsub, which is a more advanced router with mesh formation and gossip propagation. See [spec](https://github.com/libp2p/specs/tree/master/pubsub/gossipsub) and  [implementation](https://github.com/libp2p/go-libp2p-pubsub/blob/master/gossipsub.go) for more details.

 For instance, to capture the trace as a json file, you can use the following option:
 ```go
-pubsub.NewGossipSub(..., pubsub.NewEventTracer(pubsub.NewJSONTracer("/path/to/trace.json")))
+tracer, err := pubsub.NewJSONTracer("/path/to/trace.json")
+if err != nil {

+pubsub.NewGossipSub(..., pubsub.WithEventTracer(tracer))
 ```
 
 To capture the trace as a protobuf, you can use the following option:
 ```go
-pubsub.NewGossipSub(..., pubsub.NewEventTracer(pubsub.NewPBTracer("/path/to/trace.pb")))
+tracer, err := pubsub.NewPBTracer("/path/to/trace.pb")
