According to Planet Daily, Cardano founder Charles Hoskinson criticized Vitalik Buterin for not acknowledging Cardano (ADA)'s innovation in staking in an article published on the X platform. Previously, Vitalik discussed the Ethereum roadmap in an interview and proposed to redesign Ethereum's staking system to solve the problem of centralization. Vitalik discussed the possible use of the UTxO approach to solve these challenges. This model is different from Ethereum's account-based system and has been used by some blockchains, such as Bitcoin and Cardano. Crypto community members quickly pointed out that the solution is similar to the approach taken by Cardano in its staking system. Charles Hoskinson's response to Vitalik's remarks was clearly ironic. He wrote: "Don't worry, Ethereum 3 will solve all problems."
