Ethereum targets quantum-safe L1 by 2029 with Hegotá upgrades

Ethereum's aggressive timeline for post-quantum security signals that major L1s are treating quantum risk as a present-day design constraint rather than a distant hypothetical. The pairing of account abstraction with censorship resistance suggests the upgrade is as much about governance and user agency as it is about cryptography. For the broader RWA and DeFi ecosystem, this sets a benchmark for how legacy networks might approach quantum readiness, potentially pressuring others to publish concrete roadmaps. The open question is whether Hegotá's scope can deliver both technical hardening and meaningful architectural changes within that window, and how the transition will handle existing assets and contracts.
