Auther: Hitesh Songra Email: [e-mail] Linkedin: https://www.linkedin.com/in/hgsongra/

Task is to create a simplified P2P distributed exchange

• Each client will have its own instance of the orderbook.
• Clients submit orders to their own instance of orderbook. The order is distributed to other instances, too.
• If a client's order matches with another order, any remainer is added to the orderbook, too.

Requirement:

• Code in Javascript
• Use Grenache for communication between nodes
• Simple order matching engine
• You don't need to create a UI or HTTP API

Setup

npm i -g grenache-grape

# boot two grape servers

grape --dp 20001 --aph 30001 --bn '127.0.0.1:20002'
grape --dp 20002 --aph 40001 --bn '127.0.0.1:20001'

Setting up server

Move to server directory and install dependencies and execute index.js file

cd server
npm i
node index.js

Setting up client

Move to client directory and install dependencies and execute index.js file

cd client
npm i
node index.js

Above all steps needs to be performed on separate terminal tabs.

Refer server and client terminal tabs for outcomes.

Thanks for the opportunity.
