💡 Theory about the Deterministic Key in the Bitcoin Puzzles
The creator said:

"Just consecutive keys from a deterministic wallet (masked... to set difficulty)"

So they generated private keys using a simple k = k + 1 scheme.

➡️ If we find the starting key, we can rebuild the entire sequence, and recover all the puzzle private keys → 🎯 Jackpot.

But here's the issue:

Puzzle 1 uses key 1

The previous key would be 0

But private key 0 is invalid in Bitcoin (1 ≤ k < n)

👉 That means key 1 is either the true first key, or just the first accepted one after filtering.
Either way, finding the original key would let us regenerate the whole series.
