Alternative to PoS and PoW or any existing concensus mechanism

We need new idea now. Not PoW or PoS. Both are not sustainable. We need to have something where certain number of miners are randomly selected and grouped together in a group and rewarded for each block. Then for next block reward another random group needs to be created. So, chances are always there for one to get rewarded.

What are you talking about? With Proof of Work and Proof of Stake, everyone is ALWAYS rewarded for their shares. What you're proposing is that a chunk of miners randomly be rewarded the entire block, regardless of how much they are contributing to the network. This creates the chances for someone to NEVER get rewarded.

Did you even put any thought into your idea or you just simply came up with it while daydreaming and decided to post it to increase your post count?
You claim that PoW is not sustainable yet your idea is very similar to it. Why would you even think that they are not sustainable?

What a bad idea that you just suggested right there !!
Miners are regularly credited for their number of shares that they contribute in a certain mined block and everyone is happy about it.

INSTEAD, you want only a small group of people to get rewarded while everyone else has to go and cry,pray that they're selected ?
This is one of the funniest worst ideas I've ever heard of. Plus no one would even bother to mine if this is the case since they'd probably waste way more energy.

The system is currently well and is at its best. Guess what millions and millions of dollars are put in them. You need to go back to sleep. This is enough internet for today for you.
