Is Proof of Stake the Green Solution?

Alex De Vries: If you run on proof of stake, or well, and I must say, it's not the only alternative to the process that is responsible for so much energy consumption in Bitcoin. But it is definitely the most popular alternative. And we see that there are many cryptocurrencies already available in the market that are running on Proof of Stake. So if you do that, and if that becomes the standard for the industry, then a big part or almost the entirety of the energy consumption could be solved.
