 When the `defaultBootstrap` parameter is set to `true`, your node will be bootstrapped using the [default bootstrap method](/guides/js-waku/configure-discovery#default-bootstrap-method).

 :::tip Congratulations!
 You have successfully sent and received messages over the Waku Network using the `Light Push` and `Filter` protocols. Have a look at the [light-js](https://github.com/waku-org/js-waku-examples/tree/master/examples/light-js) and [light-chat](https://github.com/waku-org/js-waku-examples/tree/master/examples/light-chat) examples for working demos.
