Whether the community sees value in pursuing this before a CRQC exists I can't speak for others but I think this is definitely useful **before** a CRQC exists. It'd be too late for the 6.9 million BTC you mentioned when there is CRQC. :) > revealing the full public key only at spend time in the witness =E2=80=94= similar to how P2WPKH works today. I think it'd be useful to highlight that unlike a P2WPKH address, the address remains quantum-resistant even after its public key and signatures are revealed. -- Regards, Zeeshan Ali Khan --=20 You received this message because you are subscribed to the Google Groups "= Bitcoin Development Mailing List" group.
