-## Demo 1:  DHT for Connecting Peers & Sharing Content (Go and JS nodes)
+## Decentralized messaging network that anyone can broadcast/subscribe messages anonymously. 
 
-**Directory**:  `content-dht-provide-find`
+Anonymity is achieved by implementing Dandelion protocol on top of libp2p's pub/sub module, dandelion is a privacy preserving protocol to make message sender anonymous, it has 2 phases, the first phase is stem phase, where messages go through a psuedo-random path, the second phase is fluffing, when the message reaches the last node(randomly chosen), the message is diffused to its surrounding peers, so the third party observer cannot track back the node original node who send the message, because the message is relayed through an anonymous graph.
+Message broadcasting is implemented by libp2p floodsub.

-**What it demonstrates:**  A new DHT is created by the Go program `dht-interop`.  In a separate terminal or machine, a Node.js program connects to this DHT.  One connected, each verifies that it can find the other's content via the DHT.
 
-**First terminal:**
-```
-cd content-dht-provide-find
-make
-./dht-interop -b ../util/private_key.bin.bootstrapper.Wa
-```
-
-`-b` means bootstrap mode.  In this example, the go program is always the bootstrap node, so `-b` is always required. (***TODO***:  eliminate this superfluous option)
-
-Note that the node ID of `dht-interop` is always `Qm...6aJ9oRuEzWa` because it is being read in from `../util/private_key.bin.bootstrapper.Wa` (a private key marshalled to X.509 generated by the program `util/private-key-gen`).  This is to keep the peer id of the bootstrap server stable across invocations.
-
-**Second terminal:**  run the command printed out by dht-interop, replacing 127.0.0.1 with the IP of the server where dht-interop is listening.  Example:
-
-Running the Node.js program:
-```
-cd content-dht-provide-find/js-dht-test
-npm install  # first time only
-node js-dht-test/index.js /ip4/127.0.0.1/tcp/5555/ipfs/QmehVYruznbyDZuHBV4vEHESpDevMoAovET6aJ9oRuEzWa

 **Conclusion**
 
-You now have a chat app on a private libp2p network where each node can exchange messages using PubSub.
