Direct Quote
"Of course they have to be confiscated. If and when (and that's a big if) the existence of a cryptography-breaking QC becomes a credible threat, the Bitcoin ecosystem has no other option than softforking out the ability to spend from signature schemes (including ECDSA and BIP340) that are vulnerable to QCs. The alternative is that millions of BTC become vulnerable to theft; I cannot see how the currency can maintain any value at all in such a setting."
Source
Cited by Jameson Lopp in "[bitcoindev] Against Allowing Quantum Recovery of Bitcoin" thread, Mar 16, 2025 — Google Groups
BIP-341 (Taproot) commentary
"While the usage of public key hashes is often said to protect against ECDLP breaks or quantum computers, this protection is very weak at best: transactions are not protected while being confirmed, and a very large portion of the currency's supply is not under such protection regardless." — BIP-341
BIP-324 (v2 Transport)
Co-author; notes future protocol versions could include "post-quantum cryptography upgrades to the handshake" — BIP-324
Summary
Acknowledges quantum risk is real but considers it a "big if." When/if it materializes, strongly advocates confiscation of vulnerable coins as the only viable path. Embedded quantum future-proofing in both Taproot and BIP-324 design.

Mailing List — BIP-360 Review
"I am not quite convinced that adding three PQ schemes to the Bitcoin consensus protocol is a great solution to the problem of not being sure which exact scheme to pick. Offloading this decision to users does not really solve this problem. Moreover, this adds massive complexity and new cryptographic assumptions to the protocol." — Feb 21, 2025. gnusha.org

"For all the claims of progress on quantum computing hardware, the fact still remains that no-one is even close to demonstrating cryptographic-relevant quantum computing capabilities and the actual cryptographic-relevant capabilities of real hardware are laughable. It's still an unknown whether or not they are physically possible, and outside of the part of the physics community that would like to sell you a quantum computer - or research developing one - they're widely belived to be not physical. Hence, these are still vague unknown weaknesses. Until progress is less vague, actively freezing peoples' coins is not going to happen." — Jul 19, 2025. gnusha.org

Mailing List — Against Quantum Recovery
"I don't think that in practice we can deploy a PCQ scheme without at the same time making a decision with regards to burn vs free-for-all. The best we can do is to have all that stuff well researched and tested long before on a signet... In principe a PQC tap leaf scheme could be proposed in a BIP and activated in a soft-fork, without having to decide on the burn issue. Any time your wallet needs to generate a new address, it could add such a tap leaf just in case. But this adds a bunch of complexity to wallets, makes descriptor backups longer, etc. So adoption might be minimal. And since no sane person spends from the PQC path, we'd have no idea how much adoption there is. More importantly, the activation of a PQC tapleaf soft fork would not be sufficient to permanently migrate coins... I doubt that soft forks which nobody intends to use will be activated anytime soon." — Mar 18, 2025. gnusha.org
Summary
Pragmatic skeptic: believes PQC deployment and the confiscation/burn decision are inseparably linked. Questions whether "hidden PQC keys" approach leads to any real adoption.

Direct Quote (Feb 2025 — BIP-360 thread)
"If we want to do something like this in the short to medium term, IMO we should strip out all the signature schemes that are anything more than quite straightforward in their security assumptions (i.e. only keep hash-based signatures, maybe just SPHINCS+), only embed them in a taproot leaf, and call it a day." — Feb 21, 2025. gnusha.org
Direct Quote (Mar 17, 2025 — Against Quantum Recovery thread)
"I think this is a strong motivation to do 'simple PQC' today - while we don't need to decide on the tough question of seizing non-PQC coins today, we want to have the option to do so in the future... Thus it seems like time we add the simplest form of PQC we can — a trivial OP_HASHBASEDSIG (probably SPHINCS+) to tapscript to enable wallets to have hidden PQC keys (including multisig) in their taptrees." — Mar 17, 2025, 08:00 UTC. gnusha.org
