Decentralized Exchange (DEX)
The decentralized exchange is created using Grenache. It has two distinct layers:
- Network layer: Responsible for interacting with DHT and peers
- Exchange layer: encodes functionality of the exchange
Setup
Setting up the DHT
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'
Install dependencies
npm i
Running
Run first client
npm run client1Run second client
npm run client2TODOs
Initialization
- The clients should, on the first run, request the existing distributed order book. They do not do that now.
Race condition
- The clients use the Bittorrent DHT hashing algorithm to relize a distributed locking which is not ideal.
- The clients do not handle race condition well due to missing mutex unlocking. See more here.
Price of trades
- The order matching code does not consider price. So the exchange does not support LIMIT orders.
