Trezor CTO Outlines Trade-offs of Bitcoin’s Leading Post-Quantum Signature Scheme

The significance here is less about a specific technical choice than about where the burden of quantum readiness lands: on wallet makers, who must absorb compromises that protocol-level discussion often treats abstractly. Hardware wallet vendors sit closest to the user-facing edge of any signature migration, so their CTOs airing trade-offs signals that implementation friction, not just cryptographic theory, will shape timelines. The item leaves the scheme and the compromises unnamed, which limits how much can be judged. Worth watching is whether other wallet manufacturers publicly corroborate or contest this framing of the difficulty.
