Today in Crypto: Charles Hoskinson: Ethereum Is Copying Cardano’s EUTXO Model Without Credit

In the current cycle, cardano founder Charles Hoskinson has yet again accused Ethereum developers of adopting Cardano’s Extended Unspent Transaction Output (EUTXO) architecture after an Ethereum Foundation researcher proposed a new native UTXO payment model recently.

Ethereum Foundation researcher Toni Wahrstätter published a proposal introducing native unspent transaction outputs (UTXOs) as one-shot payment objects on Ethereum, meaning the objects would exist only temporarily rather than creating permanent account records.

Wahrstätter wrote that the model could reduce permanent state use by roughly 99.8% for payment workloads that do not require persistent state, a significant efficiency gain for a network that has struggled with long-term state bloat.

The proposal builds on Ethereum’s upcoming Frame Transactions standard, EIP-8141, and aligns with co-founder Vitalik Buterin’s Lean Ethereum roadmap, an initiative aimed at simplifying the network’s architecture and slowing state growth.

The proposal remains in the research phase, and no formal Ethereum Improvement Proposal (EIP) has been filed.

Hoskinson responded quickly, arguing that the concept mirrors work Cardano has spent roughly a decade developing.

He also noted earlier this month: It’s literally a crime in the Ethereum inner circles to mention Cardano.

EUTXO is the biggest innovation of the smart contract world and Ethereum cannot mention it as they literally try to copy it.
