Charles Hoskinson<\/strong> is not one to mince words. The founder of Cardano<\/strong> has fired back at Ethereum’s latest protocol improvement proposal, EIP-7841<\/strong>, which introduces mechanics inspired by the UTXO<\/strong> model \u2014 an architecture that Cardano<\/strong> has used since day one.<\/p>\n\n\n\n

For Hoskinson<\/strong>, this is neither a coincidence nor a tribute: it is unacknowledged borrowing. And he has not hesitated to describe the situation as a “crime”<\/strong>, reigniting a deep technical and philosophical rivalry between two of the most closely watched blockchains in the market.<\/p>\n\n\n\n

Beyond the controversy, a fundamental question emerges: who is truly innovating in the blockchain ecosystem, and who is following?<\/p>\n\n\n\n

EIP-7841: When Ethereum Draws Inspiration from Cardano’s UTXO Model<\/h2>\n\n\n\n

EIP-7841<\/strong> is an Ethereum<\/strong> protocol improvement proposal that aims to integrate elements of the UTXO (Unspent Transaction Output)<\/strong> model \u2014 an architecture popularized by Bitcoin<\/strong> and natively adopted by Cardano<\/a><\/strong>. Unlike the account-based model used by Ethereum<\/strong>, the UTXO<\/strong> model offers greater transaction predictability and more efficient parallel computation.<\/p>\n\n\n\n

Cardano<\/strong> has made this architecture one of its core technical pillars since launch. Its extended implementation, eUTXO (Extended UTXO)<\/strong>, enables smart contract execution while preserving the advantages of the original model. This is precisely what Hoskinson<\/strong> is calling out: Ethereum<\/strong> is now attempting to replicate what Cardano<\/strong> built and documented years ago.<\/p>\n\n\n\n

On social media, Hoskinson<\/strong> responded with sharp irony, describing the situation as “literally a crime”<\/strong> \u2014 in the symbolic sense of intellectual appropriation without credit. The comment immediately set both blockchain communities ablaze.<\/p>\n\n\n\n

A Technical Rivalry That Goes Beyond Mere Controversy<\/h2>\n\n\n\n

The debate between Ethereum<\/strong> and Cardano<\/strong> is nothing new. The two ecosystems have clashed for years over fundamental questions: speed of development versus academic rigor, rapid adoption versus formal robustness. Hoskinson<\/strong>, a former co-founder of Ethereum<\/strong>, understands the strengths and limitations of both protocols better than almost anyone.<\/p>\n\n\n\n

What is particularly notable here is the dynamic this proposal reveals. Ethereum, the undisputed leader in smart contracts<\/strong>, is now turning to mechanics that its competitors developed first. This speaks to a broader maturity within the sector, where the best ideas eventually make their way across ecosystems \u2014 but it also highlights growing tension around the recognition of innovation.<\/p>\n\n\n\n

Within the Cardano<\/strong> community, reactions are mixed. Some see this as a validation of IOHK<\/strong>‘s technical approach, while others are frustrated that Ethereum<\/strong> benefits from far greater liquidity and adoption to deploy concepts that Cardano<\/strong> has struggled to get traction with. The question of execution remains central: even the best architecture means little if the ecosystem does not follow.<\/p>\n\n\n\n

What This Controversy Reveals About the State of Blockchain Innovation<\/h2>\n\n\n\n

Beyond the founder ego wars, EIP-7841<\/strong> raises a structural question: is blockchain<\/a> innovation still proprietary?<\/strong> In an ecosystem that is open source by nature, ideas flow freely. Bitcoin<\/strong> inspired Cardano<\/strong> on UTXO<\/strong>, Cardano<\/strong> extended it, and Ethereum<\/strong> may now be poised to adopt it in turn.<\/p>\n\n\n\n

This cycle of mutual inspiration is, in reality, healthy for the industry. But it creates legitimate friction when credit is not explicitly given. The Ethereum<\/strong> community, for its part, has not yet officially responded to Hoskinson<\/strong>‘s accusations, and EIP-7841<\/strong> remains at this stage a proposal under active discussion \u2014 far from being approved or deployed on mainnet.<\/p>\n\n\n\n

For investors and developers tracking both ecosystems, this controversy is a reminder that the blockchain wars are fought just as much on the narrative front as on the technical one<\/strong><\/a>. And in this battle, Hoskinson<\/strong> has clearly chosen not to let the moment pass without repositioning Cardano<\/strong> as the original pioneer \u2014 a communication strategy that is as calculated as it is effective.<\/p>\n\n\n\n
