Proof of Work vs Proof of Stake: Basic Mining Guide
Recently you might have heard about the idea to move from an Ethereum consensus based on the Proof of Work (PoW) system to one based on the so-called Proof of Stake.
In this article, I will explain to you the main differences between Proof of Work vs Proof of Stake and I will provide you a definition of mining, or the process new digital currencies are released through the network.
Also, what will change regarding mining techniques if the Ethereum community decides to do the transition from “work” to “stake”?
This article wants to be a basic guide to understanding the problem above. If you are looking for a more detailed walkthrough, please check out our blockchain courses on Ethereum.
What is the Proof of work?
First of all, let’s start with basic definitions.
Proof of work is a protocol that has the main goal of deterring cyber-attacks such as a distributed denial-of-service attack (DDoS) which has the purpose of exhausting the resources of a computer system by sending multiple fake requests.
The Proof of work concept existed even before bitcoin, but Satoshi Nakamoto applied this technique to his/her – we still don’t know who Nakamoto really is – digital currency revolutionizing the way traditional transactions are set.
In fact, PoW idea was originally published by Cynthia Dwork and Moni Naor back in 1993, but the term “proof of work” was coined by Markus Jakobsson and Ari Juels in a document published in 1999.
But, returning to date, Proof of work is maybe the biggest idea behind the Nakamoto’s Bitcoin white paper – published back in 2008 – because it allows trustless and distributed consensus.
