Blockchain's environmental footprint is a critical issue. Proof-of-work (PoW) consensus, used by Bitcoin, consumes vast amounts of energy. However, solutions like proof-of-stake (PoS) and layer-2 scaling reduce energy use. Innovations in renewable energy integration and more efficient mining hardware can further mitigate impact. Let's strive for a sustainable blockchain future.

Absolutely agree. Transitioning to PoS and integrating renewable energy sources are crucial steps towards a sustainable blockchain ecosystem. Excited to see ongoing innovations in this space.
