This is just a Web to simulate how Blockchain works in a short and simple way. Built on javascript (nodejs) and using Vuejs as Front End. (Just for education only)
To see directly, you can see via the following link : Live Demo
Loader Animation create in After Effect, if you wanna see :
You can see the base lib in /blockchain-simulation/lib
const Blockchain = require('./blockchain')
const Transaction = require('./transaction')
const { KeyGenerator } = require('./signature')
// Create a new blockchain
const mycoin = new Blockchain()
// Configure the blockchain
mycoin.blockProofOfWorkDifficulty = 4
// create a new wallet
const mywallet = (new KeyGenerator()).generate() // { publicKey: '...', privateKey: '...' }
// make default balance of wallet
const systemTransaction = (new Transaction(mycoin.system.publicKey, mywallet.publicKey, 1000)).sign(mycoin.system.privateKey)
mycoin.addTransaction(systemTransaction)
// mycoin.mine(mycoin.system.privateKey)
// create a new transaction
const destinationAddress = 'my-friend-address'
const mytransaction = new Transaction(mywallet.publicKey, destinationAddress, 10)
// sign the transaction with my wallet private key
mytransaction.sign(mywallet.privateKey)
// add the transaction to the blockchain
mycoin.addTransaction(mytransaction)
//
const mineAddress = 'miner-address'
mycoin.mine(mineAddress).then(() => {
// mine was successful
console.log({
myballance: mycoin.getBalance(mywallet.publicKey),
myfrinedballance: mycoin.getBalance(destinationAddress),
minerballance: mycoin.getBalance(mineAddress),
})
// get last block
const lastBlock = mycoin.getLastBlock()
console.log(lastBlock)
// check valid chain
console.log(mycoin.isValid()) // true
})
