proof of stakes are not totally decentralized, POW remains the best. Ethereum should have stayed in POW and allow L2 disgest the network and other EVM. POS validators can decide to halt the entire network and take a suppose decentralized protocol offline, this recently happened to BSC network when a hacker stole some fund from of the protocols. Juno is a project I lost $1400 to, it's a POS, there was a whale account they fear could destroy the JUNO liquidity, they said he gamed the JUNO airdrop, community voted to seize his asset. Lols an asset that was already in his private wallet but staked with validators. Lols,. Good as it sounds, POS will cause many problem.
