Pre-Chat Using 'libp2p'

This prototype uses various packages from projects of Protocol Labs:

• ipfs/go-cid
• ipfs/go-ipfs-addr
• libp2p/go-libp2p
• libp2p/go-libp2p-host
• libp2p/go-libp2p-kad-dht
• libp2p/go-libp2p-net
• libp2p/go-libp2p-peer
• libp2p/go-libp2p-peerstore
• multiformats/go-multihash

It is inspired by chat-with-rendezvous

Get and build

go get github.com/programming-reactive-systems-in-go/prototypes/libp2p

Usage of ./chat:
  -b string
    	Address of bootstrap peer, <multiaddr>/<peerID>
  -r string
    	Unique string to identify group of nodes. Share this with your friends to let them connect with you

Start it with a unique identifier and default bootstrap peers

Create a new uuid, e.g. by uuidgen

uuidgen > uuid.txt

Use different terminal windows to run

./chat -r $(cat uuid.txt)

Start it with your bootstrap peer

Install IPFS if needed.

Stop the daemon, if running.

ipfs shutdown

Remove all bootstrap peers and start the daemon.

ipfs bootstrap rm all
ipfs daemon &

Choose peer address for private network.

ipfs id -f="<addrs>\n"

Create a new uuid.

uuidgen > uuid.txt
