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Hoskinson指责以太坊借鉴其EUTXO模型却不提及来源，这反映了两大公链在技术路线上的竞争加剧，但短期内更多是社区情绪博弈，而非实质性的链上创新。
📊 市场影响
该事件对ADA和ETH的币价影响有限，因技术争论难以直接转化为资金流入；但若以太坊未来正式引入UTXO机制，可能强化ETH的扩容叙事，对ADA形成长期压力。
💡 操作建议
建议观望，不要因技术口水战追涨ADA；可关注以太坊开发者后续是否明确采纳相关提案，若落地则考虑轻仓做多ETH，同时设置严格止损以防范情绪反转。
