Have you seen the news, everyone is excited about a well known blockchain, transitioning from Proof of Work to Proof of Stake.
Environmentally friendly you say?
I wouldn't understand what you're talking about because I am not sold on Bill Gates CO2 formula. I don't agree that carbon output can harm the planet.
It would be wise to realize climate science doesn't do well when it's peer reviewed, the Australian Ocean levels which have been lowering for 7000 years put a different light on human carbon outputs effect on global temperatures.
So what benefit does a transition to Proof of Stake Achieve?
When you use good modern Proof of Stake algorithms, the networks security improves.
When Zcash was originally conceived on a white paper in 2011, it was not possible to use Proof of Stake securely, this has now changed and is no longer the case. Secure Proof of Stake open ledger systems are a very new bleeding edge technology and the main benefit from the use of Proof of Stake.
I know you don't care about security though, I bet you haven't even followed the FBI's warnings about your home router, or the absolute joke wifi-6 is when you went and bought that technology.
Hope you have a good day, and hopefully you start caring about sovereignty more than low IQ science.
