The primary downside is, after all, that there’s no precise slashing rule on Ethereum. Any imposition of 1 – taking away staked tokens from validators – can be contrived and arbitrary, successfully unconstitutional. Now, you would possibly say, as a younger protocol, Ethereum’s governance needs to be malleable, however the stakes are far too excessive for that now. Ethereum is a protocol that manages tons of of billions of {dollars}’ value of worth each day. The very defensible DAO rollback (in 2016, following a $50 million hack) induced a mighty hangover that persuaded many who Ethereum was a hopelessly subjective mess, de facto managed by a small group making issues up on the fly.
