I made a Bitcoin puzzle using information contained in the genesis block created by Satoshi to generate the wallet.
The entropy is extremely low. I didn't even need to back anything up. Everything I needed was already in the genesis block.
Good luck!

If you have a question, you can include it with a transaction sent directly to this address, and I will reply with a hint.
Larger payments receive better hints. Dust transactions will be ignored.
---
Is the witness script a hash lock, a multisig, or something else?
---
The witness script is a multisig.
---
How many keys, what threshold, and how are the keys derived from genesis?
---
Two keys, both required. The rest is for you to derive.
---
Are both keys from the same genesis field, and is the function a hash?
---
Yes, both keys use the same Genesis field, and there is no hash.
---
Is the second key derived from the first, or both from genesis independently?
---
Both keys are derived independently from Genesis.
---
Which genesis field, hash, merkle, nonce, time, headline, or pubkey?
---
The Genesis Block is public. Which part of it matters is for you to discover.
---
Prize Address?Genesis field 32 bytes or smaller?
---
Give a hint at your will!
---
Can you give any hint about derivation offset/rule?
---
Solve it to find out. Maybe both.
If you can't check the Genesis block, you can also use The Times newspaper!
---
Derivation rule: root -> multisig -> mainnet -> genesis_data -> script_type
---
give another hint
---
I can't give hints without a question. Low-value transactions get bad hints; dust will be ignored.
---
Root = Times text as BIP32 seed? BIP39? raw key? genesis_data = BIP48 account?
---
root = the master key derived from the BIP39 seed; genesis_data = some data from the genesis block used as the BIP48 account number.
---
BIP39 entropy: genesis bytes/puzzle text/img/other? words 12/24? passphrase Y/N?
---
BIP39: 12 words; Passphrase: Y; Entropy: The data needed to solve it is publicly available in the genesis block.
---
Passphrase: genesis data or your own word? How long? What built the wallet?
---
Passphrase: Who received the first transaction? That's all I've got to say. What built the wallet are the tools that support BIPs 32, 39, and 48.
---
Passphrase sha256 first 8 hex? Entropy: raw 16B slice of Times or sha256?
---
No, the passphrase is a name. The entropy isn't the raw 16 bytes.
---
Do both cosigners use the same 12 words and the same passphrase?
---
Were the 12 words generated from entropy, or chosen directly as words?
---
Perhaps... but figuring that out is part of the puzzle. The 12 words were generated from entropy.
---
Is the 128-bit entropy a zero-padded number, a digest, or neither?
---
It's a 128-bit digest.
---
Passphrase fmt: first/full/middle name? spaced/joined? lower/UPPER/Capitalized?
---
Passphrase: You'll have to discover the fmt through brute force. The key question greatly narrows the search space.
---
Digest input: typed text, raw block bytes, a file, or something else?
---
The genesis block data can be viewed in binary, hex, decimal, or ASCII. If you figure out which part is being used as the entropy, just try all four forms.
Want a valuable hint? Send 50k sats and I'll reveal the public keys for this address.
---
Is the hashed part a header field, the coinbase text, or the whole block?
---
Somewhere in the genesis block. The hints reveal the puzzle's shape, not the path to its solution. Brute force will be necessary to uncover it.
---
Which block part + which hash gives the 128-bit entropy? One line.
---
Can I pay 50k for the pubkeys encrypted to this tx's input pubkey (Electrum)?
---
First 128 bits of SHA-256 hash of the genesis block's entropy.
Encrypted pubkey: 50k sats output + 1k input.

Only the keys may go encrypted; the rest should be public. Why not swap emails?

Fair enough, I understand. I might ask another one today for 30k, feel free to decline if it gives too much away. I've seen someone complaining about encrypted conversations and they are right, I benefited from public hints too and will from now on ask everything publicly. For transparency, my last question asked for the master fingerprint of one seed without the passphrase. Author declined as it would have been too easy to solve afterwards. Also, my previous encrypted question asked for the key origins (master fingerprints and derivation paths) of both cosigners. I'll keep that one private as it's strongly related to the 50k public keys question. The author is free to confirm or publish any of his replies.
---
Two quick shape questions. 1) Is the hashed input a contiguous piece of the genesis block exactly as a standard tool shows it (explorer, bitcoin-cli), or did you combine or edit parts yourself? 2) Did you get it by copy-pasting a tool's output, or by typing it yourself? Here's 10k. Let me know if my declined 30k plus this is enough, or if you'd like me to top up.
---
It's a contiguous piece of the genesis block, exactly as a standard tool shows it. I got it by copy-pasting the tool's output.

Reason for decline: The genesis block is only 2.5E-32 of the 2^128 possibilities. Revealing the seed's master fingerprint without the passphrase is basically giving away the entropy. All the secret pieces have to be cracked at the same time.

Declined for the same reason as before.
The puzzle wallet was built using secret components that are extremely weak on their own. Those components won't be disclosed or reduced to a searchable checksum. Revealing any one of them independently would turn part of the puzzle into an oracle for solving the others. So you'll have to recover the actual secret pieces and test them together. I won't provide any derived value that isolates any individual secret.

7.5k+1k, shape only about the two BIP48 account numbers. No values, no indices, no paste, no PP spelling. Reply like: 1) Y; 2) a; 3) b; 4) N.
1) Were both account numbers obtained from the genesis block data WITHOUT any hashing? Y/N
2) The two account numbers come from: a) the SAME contiguous piece of genesis data b) two DIFFERENT pieces of genesis data c) one from genesis data, one chosen freely d) other
3) How were the genesis bytes turned into the account integer? a) hex digits read as a number b) decimal digits read as a number c) a byte offset or position d) a named field's raw value (version/time/bits/nonce) e) other
4) Is either of the two account numbers >= 4194304 (2^22)? Y/N

10k prize + 1k reply. Small test vector for the procedure only for cosigner 0852014c Using the same data source and processing steps, but substituting 'cut -b 2-67' and BIP39 passphrase 'Test Example', what are 1) the first mnemonic word and 2) the resulting BIP32 master fingerprint? These are arbitrary test inputs; no actual puzzle cut, passphrase, seed, or account numbers are requested. Feel free to decline either part if needed.
---
10k, public test inputs only, no secrets. Your 10-16 reply c85bcea3 (cut -b 2-67, Test Example, 0852014c) does not match ANY standard pipeline we can build: one 570-char lowercase raw hex line gives d1642212 (no LF) or a9be51f9 (with LF). So one step differs. For that same 2-67 test run, please report:
1) first 40 chars of the exact text fed to sha256sum
2) its byte length (wc -c)
3) first 8 hex of the sha256sum output
4) exact command line(s) or tool steps, from source to sha256sum, with the cut range shown as 2-67
5) where the source text came from (URL/command) and how it was saved (file/paste/editor)
If any item would reveal a secret, answer the others.

1) Declined; 2) c85bcea3.

Declined. For a test vector with predefined inputs, I can only provide the final result. Step-level answers would be the same as uncovering the individual secrets one by one.

10k+1k. Test vectors with predefined inputs, final result only, as you offered. For cosigner 0852014c, run your own source and processing steps unchanged, substituting only the cut range below and BIP39 passphrase Test Example. Reply with the BIP32 master fingerprint for each:
1) cut -b 1-1
2) cut -b 2-2
3) cut -b 3-3
4) cut -b 1-4
5) cut -b 1-2000
6) cut -b 263-400
7) cut -b 1-66
Reply like: 1) xxxxxxxx; 2) ...

10k+1k. Test vectors with predefined inputs, final result only, same as your last answer. For cosigner 0852014c, use your own procedure and settings unchanged, except that the cut output is the literal text given below instead of a cut of the block, with BIP39 passphrase Test Example. Reply with the master fingerprint for each:
1) 0
