Ronaldo-Coin

A blockchain made using TypeScript

This is a demo blockchain contains features such as Proof of Work(PoW) [with specific difficulty], signing transactions(with private key), verifying transactions(with public key), etc.

Made using TypeScript, also compiled down to javascript.

You can check the typescript source code in ./src.

Features

• Proof of Work(PoW) [with specific difficulty].
• Create public/private keys.
• Signing transactions(with private key).
• Verifying transactions(with public key).
• Checking the balance of a specific address.
• Checking the validity of the blockchain.
• Visualizing the whole blockchain.

Installation

1) Clone the repository:

git clone https://github.com/SD170/blockchain-ronaldo-coin

2) Install all the dependencies:

On the project root folder, run:

npm install

3) Run the project:

You can run the project easily by using:

npm start

4) Generate new key-pair(not mandatory):

You can generate a new public/private key pair

node ./dist/keyGen.js 

Now you can test it in the ./dist/server.js.

Libraries used

Used a few libraries, few of them we're needed for development only:

• crypto-js - For using related important algorithms such as SHA256.
• elliptic - To use EC algorithms for creating Public/Private keys, sign/verify transactions.
• typescript(Dev) - Used as the base language.
• ts-node(Dev) - TypeScript execution and REPL for node.js.
• node.js - To run the compiled JS.

Thanks for checking it out. Have a great day.
