Proof of Work vs. Proof of Stake
These are consensus mechanisms used by blockchains. Proof of Work (used by Bitcoin) requires miners to solve puzzles to validate transactions. It’s secure but energy-intensive. Proof of Stake (used by BNB Chain, Ethereum 2.0) selects validators based on staked tokens — it’s faster and eco-friendly. Understanding these systems helps you choose projects based on sustainability and speed.
