| While Proof of Stake (PoS) systems are often praised for their scalability and energy efficiency, centralization concerns have drawn criticism to the system. Beyond only centralization, there are other issues to be concerned about, such as the possibility of wealth concentration and self-censorship. These can seriously jeopardize the fundamental principles of blockchain if not addressed properly. The recent transition of DarkFi from the PoS-based Ouroboros Crypsinous protocol due to wealth concentration findings, motivated us at Nomos to conduct our own investigation into the matter. We found that wealth concentration does not emerge from a PoS system driven by Crypsinous leader election function if certain conditions are met.This article delves deeper into our findings about stake relativization and the role of VRFs in the Praos leader election function. |
