Collections
Ten collections on five chains. Each page says what the puzzle was and what the records carry. The facts strip is read off the library when the page builds.
Every collection answers the same calls: get, require, all, solved, unsolved, withPubkey, count, verify, balance. What changes is the puzzle itself. A search over a key range. A brainwallet passphrase. An image with a seed hashed into it. A script that pays for a hash collision. A thread explains those once and a dataset forgets them. So each page here writes them down next to the numbers.

What every page says
- The facts strip at the top is read off the collection in the build. The counts and prize sums can't drift from the records.
- The prose says what the puzzle asks, what's known about its keys, and how the records are written. One record is quoted the way it sits on disk.
- Quirks get named. A status that needs explaining, a prize that shrank, a passphrase nobody has. The page says so instead of leaving it to the thread.
Playground
The page behind puzzles.agntn.dev/playground runs the library in your browser. What it can tell you and what it leaves alone.
Bitcoin puzzle transaction
256 addresses whose keys are 1 to 256 bits wide. The one every scanner runs against. Keys published up to 135 bits and 77 addresses still funded.
