Sounds like you need to fork and start your own coin/chain. Bitcoin is not easy to change on the base protocol level, if there is any contention it will not be adopted, the idea of making backward breaking changes as you describe and introducing proof-of-stake is not a subtle change and has no chance of being pursued.
There are parts of Bitcoin which have become ossified, that are close to impossible to change even with consensus, if not impossible. Changing those parameters would be breaking the protocol, and break how everything has been sticking together.
Sorry , you are 12 years old T-Man aka Wind_Fury, you really don't know what is possible and what is not.
Perhaps take some programming classes when you get to high school.
Kohas7787, is that you? I told you, I’m franky1’s doppleganger. Call me franky2. Hahaha.
If talking about changing Bitcoin POW, then you are debating the impossible. Changing it will break the very structure that’s making the whole system stick together. It’s a pointless debate. Satoshi’s breakthrough is actually his implementation of POW in Bitcoin.
