A consensus mechanism exist not entirely to stop attacks, they exist to make people not be attackers. In a peer-to-peer network, where there are no 3rd party system to approve people's action, without any consensus mechanism, nodes (people to be simple) will agree with the majority, but people can start being attackers and take control of the majority, so we need a consensus mechanism. This method will play a really important role when our blockchain is ran on a p2p network.

Throughout the article, I will be using the object-oriented programming style, so I expect you to know basic knowledge about it.Īs I have said, a block is just an object that has some information on it, so we should have a Block class like this:Įnter fullscreen mode Exit fullscreen mode

We are using Node.js for this project, so be sure to install it if you haven't. have way more complex stuff, but we are staying simple in this article. Modern platforms like Ethereum, Cardano, Polkadot. Its data must be immutable and unhackable. Technically, a blockchain at its bare minimum is just a list containing objects that have some basic information on it like timestamp, transactions, hash. You can check it out for more details.Īlso, my new article is released, check it out! It's about creating transactions for our blockchain, basically the first step of building a cryptocurrency.īefore we do any coding, we need to understand what a blockchain is. There's also my full tutorial on Youtube. In recent years, cryptocurrencies and blockchains are two uprising fields, so today, I will share my way of creating a blockchain in Javascript in just 60 lines of codes.
