Ethereum Foundation proposed adding UTXO model elements to curb database growth, as Cardano creator Charles Hoskinson accused the network of copying his project's decade-old architecture.
"Cardano has spent 10 years researching and implementing the extended UTXO model, and seeing Ethereum adopt it without any attribution is a significant oversight," Hoskinson said, according to a report by The Crypto Basic. He claimed the Ethereum team has made any mention of Cardano taboo within its development circles.
The proposal, published by Ethereum Foundation researcher Toni Wahrstätter, outlines a UTXO-based payment system designed to reduce network congestion. It explicitly credits Bitcoin's one-time payment model as inspiration but makes no mention of Cardano's extensive work on the extended UTXO framework, according to the Ethereum Foundation's proposal. The extended UTXO model processes transactions as one-time events rather than through a stateful method, which can reduce network load and improve scalability.
The dispute highlights growing competitive tension between the two largest smart contract platforms. For Ethereum, adopting UTXO elements could help address long-standing scalability concerns as its state database expands. For Cardano, the validation of its architectural choices by a major competitor could boost developer sentiment toward its ecosystem. The proposal is expected to be reviewed by the Ethereum community as discussions over its technical approach continue.
