Hoskinson Accuses Ethereum of Copying Cardano's UTXO Model Without Attribution

Charles Hoskinson, founder of Cardano (ADA), has accused the Ethereum Foundation of copying its extended Unspent Transaction Output (UTXO) model without credit. The UTXO model is a key technical concept that processes transactions as one-time events rather than through a stateful method, which can reduce network load and improve scalability.

The Ethereum Foundation recently published a proposal outlining a UTXO-based payment system designed to reduce network congestion. However, the proposal explicitly credits Bitcoin's one-time payment model as the inspiration but makes no mention of Cardano's extensive work on the extended UTXO framework.

Hoskinson claims that this omission is significant, as Cardano's research and implementation over the last decade directly contributed to the viability of such a model for smart contract platforms. He suggests that Ethereum may copy other Cardano innovations in the future if this pattern continues.
