Progress towards cryptographically relevant quantum computers continues to accelerate. Ethereum is taking the risk seriously. In this talk I will give an update on (1) the state of quantum computing and plausible planning timelines, (2) how Ethereum is affected: transaction signatures, BLS aggregation, and KZG commitments, (3) recent progress towards quantum readiness, including the EF’s post-quantum workstreams, specs, and devnets. The talk targets a general Ethereum audience and aims to be both an introduction and a grounded outlook.
