some newer Blockchain networks are being designed to be more energy-efficient, such as the Proof-of-Stake (PoS) consensus algorithm, which uses significantly less energy than the traditional Proof-of-Work (PoW) algorithm.

while Blockchain technology can indirectly contribute to environmental pollution, there are efforts being made to address this issue. As the technology continues to evolve, I am optimistic that we will find more sustainable and eco-friendly ways to power Blockchain networks. Thank you for raising this important topic in your comment.
