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
Charles Hoskinson 指责以太坊悄悄抄袭 Cardano 的 EUTXO 模型，虽表面是技术口水战，但反映出两大公链在扩容和状态管理上的趋同竞争。
📊 市场影响
短期对 ADA 和 ETH 价格影响有限，但若以太坊正式采纳类似 UTXO 方案，可能提升其技术叙事，压制 ADA 的差异化优势。中长线看，这或加剧 Layer1 公链间的技术内卷。
💡 操作建议
建议持有 ADA 的投资者关注 Cardano 后续技术升级节奏，若其无法在速度或成本上保持领先，可考虑减仓。ETH 持有者无需过度反应，应聚焦坎昆升级后的实际链上数据表现。
