Leptin 🔗
A cryptocurrency completely built in Nodejs.
> This is a continuing project based on [blockchain-in-node](https://github.com/amazingandyyy/blockchain-in-node/).
## Why another repo?
> Because blockchain is different from crypto!
- After building a [blockchain](https://github.com/amazingandyyy/blockchain-in-node) in node, I want to build a crypto which impelement address, signatures, transactions, and broadcasting features.
- Learning to build a crypto can help us understand **how to customize blockchain state** to match our application needs and **revealed the power of blockchain**.
## This is a lovely demo for
- Idea of how Blockschain, Mining, Nodes, Transaction work with each others.
- Network synchronizing with websocket
- Transactions(p2p sending)
- Wallet (calculating balance)
- secp256k1(encrypt/verify/sigital signatures),
- Mining(proof of work) and Rewards
- Dynamical difficulty
## Run it on your machine
```
$ git clone https://github.com/amazingandyyy/leptin.git
$ npm i
$ npm run dev
// you will have
$ [socket] listening on 5001
$ [server] listening on 3001
$ HTTP_PORT=3002 P2P_PORT=5002 PEERS=ws://localhost:5001 npm run dev
$ HTTP_PORT=3003 P2P_PORT=5003 PEERS=ws://localhost:5002,ws://localhost:5003 npm run dev
```
