Ethereum Sharing
summary
Argues that L2s can reuse four Ethereum modules—settlement, data availability, sequencing and execution—to inherit ~$150B of Ethereum security and restore cross-rollup fungibility. Proposes based sequencing where L1 proposers act as universal sequencers, enabling shared pre-confirmation and synchronous super-transactions using realtime proving plus liquidity providers; names Tao and Aztec as early movers. Describes an EVM verification pre-compile to verify EVM state transitions, remove gas limits and enable programmable execution sharding.
