Charles Hoskinson Slams Criticisms of PoS Consensus Networks Alongside Ethereum’s Vitalik Buterin

As Ethereum inches toward the merge – the last phase of its transition from proof-of-work (PoW) to Proof-of-Stake (PoS) consensus.

As Ethereum inches toward ‘the Merge’–the last phase of its transition from Proof of Work (PoW) to a Proof of Stake (PoS) consensus mechanism – the network has been taking criticism for moving away from PoW, which Bitcoin currently runs on.

Buterin Slams Jimmy Song for PoS Comments 

Popular Bitcoin developer and contributor Jimmy Song has criticized PoS consensus networks for not addressing the Byzantine General’s Problem – the difficulty decentralized systems encounter in agreeing on a single truth.


Jimmy Song asserted that PoS blockchain networks do not “provide a decentralized consensus,” adding that the people who disagree with his opinion “are completely unqualified to make any claims about Proof of Stake.”

Reacting to Jimmy Song’s claims, Ethereum Co-Founder Vitalik Buterin wrote on Twitter that the attack on PoS systems was “dumb” since he was basing it on a technicality of definitions.

Charles Hoskinson Joins Buterin in Shading Song

Charles Hoskinson, the founder of Cardano–the most actively developed crypto project on the market–joined Buterin in reprimanding Song for his comments on PoS networks.


According to Hoskinson, Song’s take on PoS networks was simply labled “stupid.” The Cardano founder wrote on Twitter:

On the Flipside

  • The PoW model is not without its own criticisms, as jurisdictions around the world have raised concerns over the energy consumption rates of PoW, which are widely viewed as environmentally unsustainable.

Why You Should Care

PoW and PoS take different routes to reach consensus, hence the differing views between these developers.
