Hoskinson Says Ethereum Is Trying to Copy Cardano's Extended UTXO Charles Hoskinson says Ethereum $ETH is attempting to copy Cardano's Extended UTXO, or EUTXO, while refusing to acknowledge its origins. This comes after Ethereum Foundation researcher Toni Wahrstätter shared a

What happened

Charles Hoskinson, founder of Cardano, publicly claimed that Ethereum (ETH) is attempting to copy Cardano’s Extended UTXO (EUTXO) design and is not acknowledging that the idea originated from Cardano, noting this comment followed a post by Ethereum Foundation researcher Toni Wahrstätter.

Confirmed

Global impact / market context

If Ethereum adopts a similar EUTXO model, it could change how smart contracts handle transaction data, potentially improving scalability and security. This rivalry may influence developer choices, investment flows, and the competitive positioning of both blockchain platforms.

Analyst inference

The blockchain sector is seeing intense competition as major platforms seek technical upgrades to attract users and capital. Debates over intellectual property and feature copying reflect broader pressures to innovate while maintaining community global trust.

Analyst inference

What to watch

1. Watch for any official Ethereum announcement or roadmap update indicating adoption of an EUTXO‑style feature, which would confirm the platform is moving toward Cardano‑like transaction handling. Analyst inference
2. Monitor Cardano’s leadership statements or code releases that address the copying claim, as a response could shape ADA’s community perception and future development focus. Analyst inference
3. Observe reactions from the Ethereum research community, especially any follow‑up comments by Toni Wahrstätter, to gauge how seriously the EUTXO idea is being considered. Analyst inference
