Echo Demo

This example demonstrates a simple echo protocol.

$ python -m pip install libp2p
Collecting libp2p
...
Successfully installed libp2p-x.x.x
$ echo-demo
Run this from the same folder in another console:

echo-demo -p 8001 -d /ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAmAsbxRR1HiGJRNVPQLNMeNsBCsXT3rDjoYBQzgzNpM5mJ

Waiting for incoming connection...

Copy the line that starts with echo-demo -p 8001, open a new terminal in the same folder and paste it in:

$ echo-demo -p 8001 -d /ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAmAsbxRR1HiGJRNVPQLNMeNsBCsXT3rDjoYBQzgzNpM5mJ
