Woofun AI reports that Charles Hoskinson has publicly accused the Ethereum Foundation of replicating the extended Unspent Transaction Output (UTXO) model developed by the Cardano ecosystem, alleging a lack of proper attribution for this core technical concept.

Structurally, the extended UTXO model diverges from Ethereum’s traditional account-based approach by processing transactions as one-time events rather than through a stateful method. This architectural difference is cited as a critical factor in reducing network load and enhancing scalability within smart contract design.

Per Woofun AI, the Ethereum Foundation recently published a proposal for a UTXO-based payment system aimed at alleviating network congestion. While the document credits Bitcoin’s one-time payment model as its inspiration, it omits any reference to Cardano’s extensive work on the extended UTXO framework, fueling Hoskinson’s criticism.

Hoskinson argues that Cardano’s research and implementation over the last ten years directly contributed to the viability of such models for smart contract platforms. In the open-source blockchain industry, while idea replication is common, crediting original developers remains essential for maintaining community trust and fostering collaboration.

This dispute underscores the competitive tension between Cardano and Ethereum as both vie for dominance in smart contract functionality and scalability solutions. The outcome may influence developer sentiment and project partnerships, highlighting how questions of innovation credit and technical lineage will increasingly shape industry dynamics.
