Lesson Overview

1.12 – Proof of Stake and Its Energy Savings: Proof of Stake reduces blockchain’s energy use by replacing mining with staking. Validators lock up a portion of their cryptocurrency as collateral to confirm transactions. If they act honestly, they earn rewards; if they cheat, they lose their stake. This model secures the network without requiring vast electricity. It’s faster, cheaper, and more eco-friendly than Proof of Work. Proof of Stake systems, like Ethereum 2.0 and Cardano, show that sustainable security is possible. The approach aligns environmental responsibility with economic incentives, marking blockchain’s evolution toward efficiency.
