Vitalik Buterin shared the third part of his article from the series “Possible Future of the Ethereum Protocol” called “The Scourge” (the name of the next network upgrade).
In his new article, he touched upon the problem of high staking centralization. He named the dominance of large stakers as one of the biggest risks, which could lead to a high risk of a 51% attack.
In October, just 2 validators (Beaverbuild and Titan Builder) produced 88% of Ethereum blocks, raising concerns about decentralization.
Buterin mentioned encrypted memory pools and fixing the staking economy as possible solutions.
