# Hypercore Extension Broadcast Test

This small application is a test on using [hypercore feed extensions](https://github.com/mafintosh/hypercore#ext--feedregisterextensionname-handlers) in order to broadcast ephemeral messages to peers on a P2P network. For that purpose, it sends single verses from Goethe's Faust (obtained from [Projekt Gutenberg](https://www.projekt-gutenberg.org/goethe/faust1/faust1.html)) to each peer that is accessing the same hypercore feed. To run this test, you'll need to have installed [Node.js](https://nodejs.org/en/) and to obtain the module's dependencies (`npm install`).

To my understanding, hypercore feeds† as well as their replication streams are encrypted and a feed's discovery key serves both for discovery as well as decryption. With the first instance of the application, we will let hypercore generate a new feed and thus, a new discovery key:

```bash

node .

```

This instance will output its discovery key. Copy it and create a second instance with this key:

```bash

node . 

```

Upon feed initialization and discovery—both peers will join the same swarm based on the feed's key—they will start sending random lines from the first chapter of Faust to each other. That's it!

† I might be wrong on that feeds itself—that is, their persistence on memory or disk—are actually encrypted, and encryption could rather be limited to network communication via the [Noise protocol](https://noiseprotocol.org/).
