Hoskinson Accuses Ethereum of Quietly Copying Cardano's EUTXO Logic

Cardano founder Charles Hoskinson accused Ethereum of quietly adopting Cardano's EUTXO logic after a new research design proposed native UTXO-style payments. The proposal, published by Ethereum Foundation researcher Toni Wahrstätter, treats simple payments as temporary, one-shot objects rather than permanent account-state entries.

The approach could cut permanent state for payment workloads by about 99.8%, because a fresh account entry uses roughly 100 to 150 bytes, while a native UTXO would leave about 0.3 bytes. This design builds on Frame Transactions and EIP-8141, and Wahrstätter credited Vitalik Buterin with raising the topic.

Hoskinson responded by saying that Ethereum developers were copying Cardano's Extended Unspent Transaction Output design without giving credit. He noted that mentioning Cardano is 'literally a crime' inside Ethereum circles and pointed to Cardano's past position as the third-largest asset on CoinMarketCap.
