Lesson 19 – Proof of Stake Introduction

Published by Mario Oettler on

In this lesson, you will learn about a consensus algorithm called Proof of Stake (PoS). While Proof of Work (PoW) is the most popular consensus mechanism among blockchains, it has some flaws like high energy consumption, centralization among miners, and low transaction throughput.

Some cryptocurrencies that apply a form of proof of stake:

  • Ethereum 2.0 (hybrid PoW and PoS model)
  • Cardano
  • Peercoin
  • Nxt
  • Blackcoin
  • ShadowCoin
  • Qtum
