Blockchain-Exploration

Implementation of blockchain fundamentals in Javascript.

Functionalities included:

• Chain generation
• User generation and joining a chain
• Coin exchange between users
• Block mining with ProofOfWork
• Checking of the chain's validity

Usage

Create a blockchain and the users.

let testChain = new Blockchain(4, 2);
let Alice= new User("Alice", 100, testChain);
let Bob = new User("Bob", 50, testChain);

Transfer coins between the users.

Bob.sendCoins(Alice.address, 20, "ETH");
Alice.sendCoins(Bob.address, 40, "ETH");
Bob.sendCoins(Alice.address, 30, "ETH");
Alice.sendCoins(Bob.address, 20, "ETH");

Check the validity of the chain

console.log(testChain.checkChainValidity());
