Ethereum Researchers Propose Running Post-Quantum Signature Aggregation on Layer 2s

A new Ethereum Research post argues that quantum-safe signatures, which are far larger than today's, will make data rather than computation the main limit on rollup scaling, and proposes applying the draft EIP-8288 aggregation scheme to OP Stack chains.

Rollups grew by moving transaction execution off Ethereum's base layer (L1). The proof that each user authorized a transaction still lands on L1 as data, however. A post published on Ethereum Research on November 2 argues that this will bec…
