Post-quantum migration and agent trust on Ethereum and Bitcoin

Ethereum and Bitcoin developers pressed forward on post-quantum account and output designs while an Ethereum standards thread refined transferable reputation for agents. The day's work stayed technical, centered on migration readiness and provenance mechanics.

Ethereum weighs quantum freeze and recovery EIP

Ethereum Magicians participants debated a draft EIP that would standardize quantum-triggered account freezing and recovery for unmigrated ECDSA accounts. The thread examines how the network might respond once quantum attacks threaten existing key material. Readers tracking long-term account safety will care because unmigrated ECDSA holdings remain a systemic exposure if Q-day arrives before voluntary migration completes.

Bitcoin PQC output types under review

Bitcoin developers on Delving Bitcoin consolidated discussion of P2MR versus P2TRv2 output types for post-quantum security and their interaction with CISA. The exchange weighs which constructions best support secure migration without breaking existing assumptions. This matters for anyone designing scripts or address formats that must remain viable under quantum threat models.

ERC-8004 advances trustless agent reputation

Ethereum Magicians discussion of ERC-8004 refined a transferable reputation model that incorporates ownership_epoch provenance, informed by cross-ERC comparisons and testnet measurements. Participants tightened how reputation can move with agents while remaining verifiable. Builders of agent systems need these provenance rules to reason about portable trust without centralized intermediaries.
