Wahrst\u00e4tter wrote that the model could reduce permanent state use by roughly 99.8% for payment workloads that do not require persistent state, a significant efficiency gain for a network that has struggled with long-term state bloat.<\/p>\n<figure id=\"attachment_833910\" aria-describedby=\"caption-attachment-833910\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/static.news.bitcoin.com\/wp-content\/uploads\/2026\/07\/charles-hoskinson-ethereum-is-copying-cardanos-eutxo-model-without-credit_nwmk.jpg\" alt=\"Charkes Hoskinson has once again accused Ethereum of stealing its eUTXO model.\" width=\"1087\" height=\"460\"  ><figcaption id=\"caption-attachment-833910\">Image source: X<\/figcaption><\/figure>\n<p>The proposal builds on Ethereum\u2019s upcoming Frame Transactions standard, EIP-8141, and aligns with co-founder Vitalik Buterin\u2019s Lean Ethereum roadmap, an initiative aimed at simplifying the network\u2019s architecture and slowing state growth. The proposal remains in the research phase, and no formal Ethereum Improvement Proposal (EIP) has been filed.<\/p>\n<p>Hoskinson responded quickly, arguing that the concept mirrors work Cardano has spent roughly a decade developing. He also <a href=\"https:\/\/x.com\/IOHK_Charles\/status\/2074597297007317093?s=20\" target=\"_blank\" rel=\"noopener noreferrer\">noted earlier this month<\/a>:<\/p>\n<blockquote>\n<p>It\u2019s literally a crime in the Ethereum inner circles to mention Cardano. EUTXO is the biggest innovation of the smart contract world and Ethereum cannot mention it as they literally try to copy it.<\/p>\n<\/blockquote>\n<p>Cardano\u2019s Extended UTXO model extends Bitcoin\u2019s original UTXO transaction structure to support smart contracts, an approach Hoskinson has long argued offers more predictable transaction execution than Ethereum\u2019s account-based model. He said Cardano\u2019s team published a paper called \u201cChimeric Ledgers\u201d explaining how to run UTXO-based and account-based systems in parallel, work he says predates Ethereum\u2019s current proposal by years.<\/p>\n<p>Hoskinson argued that deterministic transaction behavior, transactions that execute the same way regardless of network conditions, remains one of Cardano\u2019s strongest competitive advantages. He said predictable execution reduces unexpected failures, minimizes network congestion, and creates a more secure foundation for decentralized finance (DeFi) applications.<\/p>\n<h2>Part of a Broader Pattern This Month<\/h2>\n<p>Hoskinson has repeatedly criticized Ethereum\u2019s architecture and governance throughout July, arguing that Ethereum lacks an onchain treasury capable of sustainably funding long-term development. He has also used recent public appearances to defend <a href=\"https:\/\/x.com\/Cardanians_io\/status\/2080630954465390908\" target=\"_blank\" rel=\"noopener noreferrer\">Cardano\u2019s slower, research-driven development philosophy<\/a> against critics who argue the network has moved too cautiously since its 2017 launch.<\/p>\n<p>Hoskinson maintains that Cardano\u2019s real competitive edge lies less in any single feature and more in its overall engineering philosophy, arguing that competitors may copy individual technical ideas but cannot easily replicate Cardano\u2019s research-first culture.<\/p>\n<p>In any case, the technical disagreement carries real stakes for both ecosystems because if Ethereum successfully implements a native UTXO model (meaningfully cutting its state growth), the network would address one of the its longest-running scaling criticisms while potentially undercutting one of Cardano\u2019s key differentiators. Ethereum developers have not directly responded to Hoskinson\u2019s copying allegation, and Wahrst\u00e4tter\u2019s proposal has not credited Cardano\u2019s EUTXO work in its public documentation.<\/p>\n<div><a aria-label=\"Read Now: Cardano\u2019s Hoskinson Says Disputed 1,096 Bitcoin Funded a 2016 Audit Amid $70 Million Mystery\" href=\"http:\/\/news.bitcoin.com\/cardano-hoskinson-1096-btc-audit-dispute\/\"><\/p>\n<div>\n<p>Cardano co-founder Charles Hoskinson has said that 1,096 BTC, worth roughly $70 million today, held by an Isle of Man\u2026<\/p>\n<\/div>\n<p><\/a><a aria-label=\"Read Now: Cardano\u2019s Hoskinson Says Disputed 1,096 Bitcoin Funded a 2016 Audit Amid $70 Million Mystery\" href=\"http:\/\/news.bitcoin.com\/cardano-hoskinson-1096-btc-audit-dispute\/\"><\/p>\n<div>\n<h3>Cardano\u2019s Hoskinson Says Disputed 1,096 Bitcoin Funded a 2016 Audit Amid $70 Million Mystery<\/h3>\n<p>Cardano co-founder Charles Hoskinson has said that 1,096 BTC, worth roughly $70 million today, held by an Isle of Man\u2026<\/p>\n<\/div>\n<p><\/a><a aria-label=\"Read Now: Cardano\u2019s Hoskinson Says Disputed 1,096 Bitcoin Funded a 2016 Audit Amid $70 Million Mystery\" href=\"http:\/\/news.bitcoin.com\/cardano-hoskinson-1096-btc-audit-dispute\/\"><\/p>\n<div>\n<div>\n<h3>Cardano\u2019s Hoskinson Says Disputed 1,096 Bitcoin Funded a 2016 Audit Amid $70 Million Mystery<\/h3>\n<\/div>\n<p>Cardano co-founder Charles Hoskinson has said that 1,096 BTC, worth roughly $70 million today, held by an Isle of Man\u2026<\/p>\n<\/div>\n<p><\/a><\/div>\n<\/div>\n<p> Shiraz Jagati<br \/><a href=\"https:\/\/news.bitcoin.com\/hoskinson-ethereum-copying-cardano-eutxo-model\/\" class=\"button purchase\" rel=\"nofollow noopener\" target=\"_blank\">Read More<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cardano founder Charles Hoskinson has yet again accused Ethereum developers of adopting Cardano\u2019s Extended Unspent Transaction Output (EUTXO) architecture after an Ethereum Foundation researcher proposed a new native UTXO payment model recently.
