ethresear.ch: Towards Native Post-Quantum Private ETH
22:53 (Pierre). The L1 strawmap lists L1-native private post-quantum transfers as a north star. Privacy solutions in production today rely on elliptic curve primitives or unsatisfying hardware assumptions; some argue protecting against harvest-now-decrypt-later (HNDL) attacks is enough, but the post notes that once a cryptographically relevant quantum computer exists, adversaries could carry out undetectable attacks with catastrophic losses, and recovery mechanisms such as turnstiles would require heavy social layer coordination. Using Zcash Sapling (about 620k shielded ZEC) as an example, it shows that delivering post-quantum shielded ETH takes far more than switching proof systems.
