Several of the top 10 cryptocurrencies (by market cap) use "Proof of Stake" (PoS) to replace "Proof of Work". Cardano is one example, but you may not have heard of it, so let's talk about another one. The second largest cryptocurrency, Ethereum, is in the process of transitioning to PoS. This is the one that will likely have the largest impact on reducing energy use and graphics card demand. Here's a brief excerpt of how PoS makes sense: "Unlike proof-of-work, validators don't need to use significant amounts of computational power because they're selected at random and aren't competing."
