Gossip broadcast

This is a library implementating gossip protocol for general purpose message broadcast in peer to peer network.

It is similar to the one used in bitcoin or Ethereum blockchain, but this implementation is simpler and cleaner.

Usage

The usage of this library is straight forward, please see the example.

Example

build example

cd example
go build -o node 

run example

usage:

./node [topic] [listenIP:listenPort] [existingNodeIP:existingNodePort...]

Run the first node:

./node test 127.0.0.1:8000

Run second node to join the first node:

./node test 127.0.0.1:8001 127.0.0.1:8000

You can run more nodes and join any existing node with the same topic.

Input messages from stdin, and the messages will be gossiped to all the nodes.
