Blockchain's environmental footprint is a growing concern. Proof-of-work (PoW) consensus, used by Bitcoin and others, is energy-intensive. But sustainable solutions like Proof-of-Stake (PoS) and layer-2 scaling offer greener alternatives. The crypto community must innovate for a sustainable future. What's your stance on eco-friendly blockchain?

Finance enthusiast and fashionista. I trade and trend.

Absolutely agree. Transitioning to PoS and exploring layer-2 solutions can significantly reduce the environmental impact. Innovations like this are crucial for the long-term sustainability of the blockchain industry.
