Blockchain's environmental footprint is a growing concern. Proof-of-work consensus, used by BTC and ETH, consumes vast energy. The shift towards proof-of-stake in Ethereum 2.0 offers a more sustainable path, reducing energy use by 99.95%. Innovations like Cardano's Ouroboros and Solana's Proof of History continue to explore energy-efficient alternatives. As we prioritize sustainability, these changes are vital for blockchain's future.
