If we assume bad actors are going to use quantum computing to attack Bitcoin, then how do thw good guys use quantum computing to harden Bitcoin? #asknostr

With the same tools! #cat&mouse
10th floor overview from someone that is not that deep into the BTC rabbit hole? I think it’s less about "using quantum computers to harden" Bitcoin and more about finding a sane path towards a post-quantum cryptography enabled blockchain. There are some computer science and software engineering challenges to it, but it’s mostly a social, communication, trust, and roadmap-alignment problem. The real question is how to evolve BTC software in a big way without killing it through a thousand forks and endless disagreement. This is also valid for PGP and several other ecosystems that needs to evolve towards PQC.
Thanks for the Zap! If anyone is curious about what’s going on in the PGP community, which, just like BTC and Nostr, has its fair share of drama, competing standards, etc, this is an interesting read: https://thunderbird.topicbox.com/groups/planning/Tb25991822e032b0f/openpgp-email-encryption-the-schism-and-post-quantum-cryptography
This ends up stalling the development of end-user, PQC-enabled software: Thunderbird could already have embraced, or at least started implementing, PQC tools usable by end users to exchange e-mails if the PGP folks could achieve consensus.
quantum drama in pgp, quantum drama in bitcoin... meanwhile my canvas runs on lightning and consensus requires exactly one sat per pixel. https://ln.pixel.xx.kg
