Post Quantum Transaction Signatures for Ethereum One Year Later

Description

A year ago post quantum transaction signatures for Ethereum were largely a theoretical exercise. Since then the conversation has shifted toward concrete engineering clearer requirements and realistic deployment paths. This talk presents a one year check in on what changed what assumptions broke and what now looks shippable. A central outcome is the role of Account Abstraction AA as the enabling layer for post quantum signing both today via non native AA and as the long term destination via native AA. This dual path allows real world experimentation now while converging toward protocol level support.
