Ethereum Accused of Stealing Cardano's Smart Contract Innovation

Cardano founder Charles Hoskinson has accused Ethereum of quietly adopting Cardano's EUTXO logic without giving credit. This comes after a new research design proposed native UTXO-style payments on Ethereum, which would treat simple payments as temporary, one-shot objects rather than permanent account-state entries.

The proposal, put forward by Ethereum Foundation researcher Toni Wahrstätter, aims to reduce Ethereum state growth and could cut permanent state for payment workloads by about 99.8%. This approach is similar to the UTXO model used by Bitcoin, where each output is created once, spent once, and then leaves the active memory set.

Hoskinson claimed that Ethereum developers are copying Cardano's EUTXO design without acknowledging it, saying 'EUTXO is the biggest innovation of the smart contract world and Ethereum cannot mention it as they literally try to copy it.'
