What does this even mean? There is no way to "quantum harden" a secp256k1 keypair with different entropy, despite what some snake-oil salesmen are saying. A curve point is a curve point and Shor's algorithm can factor it to find its discrete log just as well as any other point. Mods, this appears to be an underinformed proposal at best, AI slop/spam, or even phishing at worst. Needless to say but I'll say it anyway: Don't use this tool to generate paper wallet keys. The keygen code is unreadable gibberish to my eye. Output entropy could be compromised in a way that only the author knows, designed to steal any money deposited into the output keys. Don't click on links to websites you don't already know & trust. DigiMancer3D, if this is not the case, please explain your proposal better and document your code. regards, conduition On Tuesday, May 26th, 2026 at 6:19 PM, '3D' via Bitcoin Development Mailing List <[email protected]> wrote: > Hi all, > I'd like to propose a new wallet-layer BIP for a practical hybrid > post-quantum key derivation scheme. > > **Title:** Hybrid SPHINCS+ / secp256k1 Key Derivation for Quantum-Resistant > Bitcoin Wallets > > **Summary:** > This BIP defines a simple, immediately usable method that combines > NIST-standardized SLH-DSA (SPHINCS+) with the 3’s Company HE-SD (High-Entropy > Seed Distillation) algorithm (which uses SPX-QEC for cleanup) to derive > ordinary secp256k1 private keys and standard Bitcoin addresses (legacy + > BIP-341 Taproot). > > The process is fully offline, runs on low-end/air-gapped hardware (Raspberry > Pi class), and produces keys that work today with Electrum, bitaddress.org, > and Bitcoin Core; no consensus changes required. > > **Reference implementation & full code:** > https://github.com/DigiMancer3D/bip-xxx-sphincs-hybrid > > **Draft BIP text:** > https://github.com/DigiMancer3D/bip-xxx-sphincs-hybrid/blob/main/bip-xxx.mediawiki > > This is intended as a practical bridge for quantum-hardened cold > storage/paper wallets while post-quantum consensus migration is still in the > future. > > Happy to answer questions, incorporate feedback, and make any changes needed. > > Thanks, > DigiMancer3D > > -- > You received this message because you are subscribed to the Google Groups > "Bitcoin Development Mailing List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion visit > https://groups.google.com/d/msgid/bitcoindev/bpSypbIuSoDinhE-Y4CrVI5LGHrJ_I79xYUzpYswA5JGkbASwibq94UozeR2jsu48vH6FZLdEBPpWHgIuVtSpUNy-tRpnGfe1hce2ti8k5w%3D%40protonmail.com. -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
