What Are the Environmental Implications of the Security Models of Proof of Work and Proof of Stake?

The environmental implications of Proof of Work (PoW) and Proof of Stake (PoS) are significantly different. PoW is known for its high energy consumption, as it requires a large amount of computational power to secure the network.

This has led to concerns about its environmental impact. PoS, on the other hand, is much more energy-efficient, as it does not rely on mining.

Validators in a PoS system are chosen based on the amount of cryptocurrency they hold, which requires minimal energy.
