Every major chain except bitcoin and ethereum is proof-of-stake now. And in less than a year, ethereum will be proof of stake. People that say proof-of-stake "won't work" have no idea what they're talking about.
Yes, eventually I believe proof of work will be replaced by other protocols such as proof of stake. This is already the case on many chains. The cost for proof of stake is minimal, as in you can run a full node on a raspberry pi.
It's not. It still uses proof of work, for now at least. They say they want to implement proof of stake. THAT will be interesting, but I want to see if they ever get there.
Proof of stake chains already secure over 50 Billion dollars in value - https://defillama.com/chains. Everything but Ethereum in the top 20 is proof of stake, Ethereum will be transitioning to it this year.
I can't tell if this is a joke or not but i'll bite. Delegated proof of stake is exactly as you describe and there are 10+ $1B chains that have this mechanism.
We have proof of stake now. The nodes could be run by the chain validators and they get a cut of the staking rewards. Look up how proof of stake works on the Cosmos chain. You could totally do this and I bet it would take off, at least in that section of the Internet that's into Cosmos/Tendermint chains. I'd use it
Don't all the chains need their own currency? I was under the impression that both proof of stake and proof of work required that there was some form of native currency so that there was some incentive to secure the network.
I could be wrong but the Lightning Network is hardly a proof of stake system, just used to open up state channels between two members for lots of off chain transactions before finalizing on the main chain.
