Native UTXOs on Ethereum
A new proposal introduces a native UTXO model that runs alongside the existing account system, targeting payment workloads where persistent account state is unnecessary. The design records UTXO existence in append-only creation logs and stores only a single spent bit per UTXO in state, reducing per-entry state from ~100-150 bytes to ~0.3 bytes and compressing 1 billion entries from roughly 150 GB to ~300 MB. Self-funded spends allow zero-ETH recipients to spend received UTXOs without a prior gas top-up, and trustless sponsorship lets third parties cover fees after verifying a repayment output exists in the same frame, removing any trust requirement between user and sponsor.
