Vitalik Buterin credited Bitcoin developers for Utreexo while outlining Ethereum’s proposed hybrid state scaling strategy.Ethereum researcher Toni Wahrstätter proposed native UTXOs that could cut payment state usage roughly 99.8%.The proposal keeps Ethereum accounts while moving simple one-shot payments into a lighter UTXO-style model.EIP-8141 Frame Transactions, required by the UTXO design, is currently only considered for Hegotá inclusion.Vitalik’s recursive-STARK mempool proposal limits proof bandwidth overhead rather than proving unlimited Ethereum transaction throughput.
