While discussing PoS voting, Vitalik Buterin called a critic’s idea an “unmitigated bare-faced lie.”

While some feel that Ethereum’s imminent switch to proof-of-stake (PoS) will propel the platform past Bitcoin (BTC), others are using the opportunity to make snide remarks on Twitter, prompting a reaction from Ethereum co-founder Vitalik Buterin.

Bitcoiner Nick Payton suggested in a tweet titled “Proof of Stakers” that voting to change the features of PoS platforms proves that PoS assets are securities. Buterin reacted to the piece by calling Payton’s ideas an “unmitigated bare-faced lie.” Buterin claims that PoS, like proof-of-work (PoW), does not contain voting on protocol settings. Buterin further noted that in both PoS and PoW, nodes reject invalid blocks.

Last week, author Jimmy Song slammed PoS, doubting the consensus mechanism’s decentralization. According to Song, the mechanism does not solve the problem of Byzantine generals. Buterin responded to Song’s ideas in a tweet, saying: 

”Pro-tip: if there’s a long-established tradition of people debating A vs B based on deep arguments touching on math, economics and moral philosophy, and you come along saying “B is dumb because of a one-line technicality involving definitions”, you’re probably wrong.”

Fellow Ethereum founder and PoS supporter Charles Hoskinson also weighed in, noting that Song’s post is “beyond explanation.”

Meanwhile, Vivek Raman, a decentralized finance researcher, has expressed optimism about the impending merge. In a Twitter thread, Raman stated that the switch to PoS provides Ethereum with the economic structure to challenge Bitcoin’s dominance in the cryptocurrency space.

Earlier in July, Ethereum performed a substantial merge trial on the Sepolia testnet, bringing the platform closer to the PoS consensus mechanism. While there have been some problems, developers have stated that the merge will not be delayed.
