# Hoskinson Accuses Ethereum of Copying Cardano’s EUTXO Model After New Research Proposal

Cardano (ADA) founder Charles Hoskinson accused Ethereum of copying Cardano’s Extended Unspent Transaction Output (EUTXO) model after an Ethereum research proposal on “one-shot” payment objects. According to BeInCrypto, Ethereum Foundation researcher Toni Wahrstätter published a design this week that would avoid permanent state entries for most simple payments by proving them from history and keeping only a spent marker in state. Wahrstätter said the approach could cut permanent state for payment workloads by roughly 99.8% and builds on the Frame Transactions standard EIP-8141, crediting Vitalik Buterin for raising the topic as he promotes a Lean Ethereum roadmap. Hoskinson said mentioning Cardano is taboo in Ethereum circles.
