Proof of Stake1 comment 2 min read
Consensus Algorithms Consensus algorithms are used by distributed systems to reach agreement. This class of algorithms has existed since computers moved from single mainframe architecture towards a network-based one. Historically, these algorithms were used in non-adversarial environments (bad nodes fail), and the most successful was Paxos). Nowadays, with increased use of blockchains, they are gaining adoption in adversarial environments (bad malicious nodes lie). The most successful is Proof-of-Work (PoW), famously used by Bitcoin and Ethereum. However, Proof-of-Stake (PoS) is gaining traction, and Ethereum will be migrating to it later in 2022.Subscribe to read this →

As thrilling as it is, learning web3 can quickly get overwhelming. This is a whole new world full of technical and cultural jargon. There is a significant barrier to entry for crypto-curious and crypto-learners.
In this newsletter, I will summarize web3 concepts in 420 words or less (and maybe some diagrams 🙈). I’m a beginner myself so the goal is to learn together.
Welcome, thanks for being here, and I hope that you enjoy it!
