⚙️ **Crypto 101: Proof of Work vs Proof of Stake**
Ever wondered how blockchains stay secure and process transactions without a boss in charge? That’s where **consensus mechanisms** come in.
Let’s break down the two most common ones 👇
---
🔨 **Proof of Work (PoW)** – Used by $BTC
✅ Miners compete to solve complex puzzles
✅ First to solve gets to add the next block & earn rewards
✅ Requires **massive computational power**
✅ High security but energy-intensive
💡 Example: Bitcoin uses PoW. Miners worldwide verify transactions and keep the network decentralized.
---
🧘 **Proof of Stake (PoS)** – Used by $ETH
✅ Validators are chosen based on how many coins they lock (stake)
✅ No heavy computing — it’s energy-efficient
✅ More scalable and eco-friendly
✅ Still very secure, but relies on economic incentives
💡 Example: Ethereum switched to PoS in 2022 (The Merge) — reducing energy use by over 99%!
---
🧠 **TL;DR:**
PoW = 🔒Security through computing power
PoS = 🔒Security through economic skin in the game
