Charles Hoskinson has accused Ethereum of adopting ideas pioneered by Cardano without acknowledgment.
The Cardano co-founder made the claim following a proposal by Ethereum researcher Toni Wahrstätter to bring native UTXOs to the network as a way of cutting long-term state storage for payment transactions.
According to Hoskinson, Wahrstätter’s research closely mirrors concepts Cardano has been developing since its launch.
“It’s literally a crime in the Ethereum inner circle to mention Cardano,” he wrote on X. “EUTXO is the biggest innovation of the smart contract world and Ethereum cannot mention it as they literally try to copy it.”
Wahrstätter’s proposal describes a payment model that stores only a small “spent” marker in Ethereum’s state while keeping the rest of the payment data in blockchain history. According to the research, this approach could reduce the permanent state required for payment workloads by as much as 99.8% without abandoning Ethereum’s account-based architecture.
The proposal borrows the one-time payment structure used by Bitcoin’s UTXO model while allowing Ethereum accounts and smart contracts to keep on operating. It also relies on the proposed EIP-8141 transaction framework to let users spend UTXOs without first holding ETH for gas fees.
Hoskinson followed up his post on X with a livestream on the same platform, where he read a tweet by Wahrstätter announcing the proposal and pointed out that it made no reference to Cardano despite his network spending years solving many of the engineering problems that Ethereum is now exploring.
“For ten years, we’ve worked on extended UTXO, smart contracts on UTXO,” he said. “We wrote a paper called Chimeric Ledgers to show how to run these two systems in parallel.”
He argued that Ethereum developers had in the past dismissed UTXO-based smart contracts as impractical before now putting similar ideas on their long-term roadmap.
During the livestream, Hoskinson expanded his criticism beyond Wahrstätter’s proposal, claiming that Ethereum has been regularly adopting ideas after dismissing them when they first appeared on Cardano.
Some of the areas he claimed such behavior had happened in included Cardano’s governance system and treasury model, which he said the Ethereum Foundation had been forced to drift toward after losing staff and money.
He also suggested that Ethereum would look to revisit Cardano’s work on privacy and post-quantum cryptography through IOHK’s privacy-focused blockchain project, Midnight, as well as its early embrace of form

🦊 小靓解读
Cardano创始人Charles Hoskinson指责以太坊研究员Toni Wahrstätter的UTXO提案抄袭Cardano的EUTXO概念，称以太坊圈子故意回避提及Cardano。这是公链间技术路线争议的又一次公开交锋，凸显智能合约平台竞争的白热化。
📊 市场影响
短期内对ADA和ETH价格影响有限，但可能引发社区情绪波动，ADA或有短线交易机会，ETH则因技术进展受关注。中长期看，若以太坊成功引入UTXO模型，将提升其网络效率，对两者均是利好。
💡 操作建议
建议交易者关注ADA在0.35-0.40美元区间的支撑位，和ETH在1900-2000美元的阻力位，可考虑轻仓布局，但需警惕事件驱动型波动风险。仅供参考，控制仓位。
