Hello saatoshi_rising,
I'm following up on your April 27, 2017 explanation of the Bitcoin puzzle construction.
I've been conducting a technical investigation into the deterministic wallet and the masking operation you described. In particular, I'm testing whether the original source keys could have come from legacy Electrum, Armory or BIP32.
I'm hoping you might be willing to clarify a few technical details:
1. Which deterministic wallet software and version did you use?
2. Was the source wallet based on Electrum's legacy MPK, Armory's chained-key system, or another construction?
3. Do you still have the original generator or its masking implementation?
4. Would you be willing to share a public-only artifact, such as the original MPK, account xpub or public root and chain code, together with the derivation-index convention?
I am not requesting any seed phrases, private keys or wallet passwords. A public-only artifact or a description of the original derivation process would be sufficient.
My goal is to reproduce the construction against already-solved puzzle addresses and independently validate the method before investigating the remaining puzzles.
Thank you for sharing this fascinating challenge with the community. Any clarification would be enormously helpful.
sorry, it’s easier to just ask for the private key right away lol
