Vitalik Looks to Bitcoin Playbook as Ethereum Eyes Major Scaling Shift

TLDR

• Ethereum co-founder Vitalik Buterin credited Bitcoin developers for Utreexo while outlining a proposed hybrid state scaling strategy for Ethereum.
• Ethereum researcher Toni Wahrstätter proposed native UTXOs that could cut payment state usage by roughly 99.8%.
• The proposal keeps Ethereum accounts but moves simple one-shot payments into a lighter UTXO-style model.
• EIP-8141 Frame Transactions, required by the UTXO design, is only under consideration for the Hegotá upgrade.
• Buterin’s recursive-STARK mempool proposal limits proof bandwidth overhead, not unlimited transaction throughput.

Vitalik Buterin, co-founder of Ethereum, credited Bitcoin developers on August 16 for their work on Utreexo. He described it as an inspiration for a proposed Ethereum scaling direction that could combine UTXO-style state, conventional dynamic state, and models in between.

Buterin called this the “current proposed Ethereum scaling strategy” in an X post, though he made clear the architecture is still under development.
