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.
Proof of BOINC is not centralized. Gridcoin used to use netsoft for credit checking, now every node participates in securing the neural network with verified BOINC statistics gathered directly from the BOINC project sites - so there is no centralization in the POB system.
DPOR generates 50k GRC per day, which is far more than interest rewarded for POS, so really it's perfect to scale out user adoption since there is no market cap. If investors hold and never crunch, they'll experience deflation of their holdings (almost demurrage).
Gridcoin is a permissionless & decentralized system.
POS centralizes control according to stake, which is a finite resource
Gridcoin is not a finite resource - there is no cap on coin supply, and DPOR rewards more than POS. Better to have BOINC users in control rather than having pool owners or ASIC manufacturers in control of the network (POW is extremely centralized & wasteful).
