Ethereum Accused of Quietly Adopting Cardano's Core Design
Cardano's Charles Hoskinson has accused Ethereum of quietly adopting its Extended Unspent Transaction Output (EUTXO) design, a core component of the Cardano protocol. This claim comes after a new research proposal was published by Ethereum Foundation researcher Toni Wahrstätter, which suggests treating simple payments as temporary, one-shot objects rather than permanent account-state entries.
The proposed design would reduce Ethereum's state growth by about 99.8%, as each payment would leave only one spent marker in the state. This approach is similar to Bitcoin's UTXO model, where each output is created once, spent once, and then removed from active memory. Wahrstätter credited Vitalik Buterin with raising the topic.
Hoskinson responded by saying that Ethereum developers are 'literally trying to copy' Cardano's EUTXO design without giving it credit. He added that mentioning Cardano is 'literally a crime' within Ethereum circles, pointing to Cardano's past position as the third-largest asset on CoinMarketCap.
