As was alluded to in the comments, my colleagues at Blockstream Research are doing some work on this with mechanisms called SHRINCS and SHRIMPS.
Of course, inventing and demonstrating a quantum-resistant signature mechanism isn't the same thing as deploying it in consensus or upgrading everyone's UTXOs to it, and it's fair to say that there are many steps in between!
- nehan 6mo agoThis work is important, and I'm looking forward to forming an opinion on it. Maybe a future post! For those who are interested, this is what I'm aware of: - Tim Ruffing proved that Taproot's commitment scheme was quantum-resilient: https://eprint.iacr.org/2025/1307 https://eprint.iacr.org/2025/1307 - Jonas Nick and Mikhail Kudinov have proposed SHRINCS: https://delvingbitcoin.org/t/shrincs-324-byte-stateful-post-quantum-signatures-with-static-backups/2158 https://delvingbitcoin.org/t/shrincs-324-byte-stateful-post-... and SHRIMPS: https://x.com/n1ckler/status/2038695067754328095 https://x.com/n1ckler/status/2038695067754328095.
