Ethereum founder and co-creator Charles Hoskinson criticized Vitalik Buterin in a tweet on Nov. 25 for not recognizing Cardano (ADA) for its staking innovations.

Hoskinson's remarks followed a recent interview where Buterin discussed the Ethereum roadmap and proposed redesigning Ethereum's (ETH) staking system to combat issues related to centralization.

During the interview, Buterin went on to potentially adopt the UTxO approach, which relies on unspent transactions, to address these challenges. This model differs from the Ethereum current account-based system and is used by some blockchains, such as Bitcoin and Cardano.
