Hoskinson Slams Ethereum EIP-8141 as Cardano Copycat

Summary

• Hoskinson accuses Ethereum of copying Cardano EUTXO model
• EIP-8141 targets state minimization for 2026 Hegota fork
• Ethereum power use fell sharply post-Merge

Charles Hoskinson accused the Ethereum Foundation of copying Cardano's decade-long work on the Extended UTXO model. He targeted the EIP-8141 proposal and its native UTXO framework for state growth control. The idea appeared in recent weeks before Ethereum's planned late-2026 Hegota fork.

Hoskinson called the move "literally a crime" without proper credit.

Context

Cardano built its smart contract platform on the EUTXO model. That choice delivered predictable execution and cut on-chain state. Ethereum stuck with an account-based model that fueled state bloat.

EIP-8141 now pushes frame transactions that borrow UTXO ideas to trim that growth ahead of the Hegota fork. Energy numbers moved on their own track. Ethereum's annual power use fell to 7.87 GWh after the Merge.

Details

beincrypto.com and coinpedia.org carried Hoskinson's direct words. He said Ethereum is taking Cardano's EUTXO model through the new native UTXO proposal and giving no credit. Hoskinson called the EUTXO approach the greatest innovation in smart contracts.

The Ethereum Foundation offered no reply in the cited reports. EIP-8141 zeroes in on state minimization for the 2026 cycle. It seeks lower storage needs while keeping smart contract flexibility intact.

"Literally a crime."

The core question remains whether EIP-8141 simply copies Cardano's earlier EUTXO work. Cardano backers point to the long research timeline. Ethereum developers have stayed silent on both timelines and any attribution plans.

Outlook

Ethereum teams will keep discussing EIP-8141 through 2026. Cardano will hold to its EUTXO base. Watch for any official word from the Ethereum Foundation on the copying claims and for more specifics on the Hegota fork.
