But it relies on centralization of the proof of BOINC and proof-of-stake, which thus guarantees it won't scale to anything significant, as vested interests will strangle it.

Btw, proof-of-stake will never scale out user adoption, because it is a vested interest paradigm, and thus will be destroyed by its stake holders. No stake holder (in any context or business model) allows a competitor to profit. Only permissionless, decentralized systems scale.
It will perhaps be good for a P&D, because so many fools believe technological nonsense because they don't understand.
