Saw you mention this thread somewhere else and thought to ask here as well so it would not get lost in the noise.

Exhibit A:
Proof of Stake (PoS) was first introduced in a paper by Sunny King and Scott Nadal in 2012 and intended to solve the problem of Bitcoin minings high energy consumption

I've got an idea, and I'm wondering if it's been discussed/ripped apart here yet:
I'm wondering if as bitcoins become more widely distributed, whether a transition from a proof of work based system to a proof of stake one might happen. What I mean by proof of stake is that instead of your "vote" on the accepted transaction history being weighted by the share of computing resources you bring to the network, it's weighted by the number of bitcoins you can prove you own, using your private keys.
If this is the case this QuantumMechanic guy should definitely be added on the list of "Notable people" imo, even tho this one one of his last posts here...
