BTC Puzzles Challenge

A Flutter app for exploring the famous 2015 Bitcoin puzzle transactions —
out now for iOS, with Android, desktop and web versions on the way.
Browse all 160 puzzles with full on-chain data, study solved dossiers with
one-tap-copyable keys, convert between HEX / WIF / addresses offline, and
run a real kangaroo (Pollard) search on your own chosen sub-range — with
honest speed reporting.

Principles

Honesty over hype — if a search is astronomically improbable, we say so.
Offline-first — our tools work fully on-device; your keys never leave it.
Real mathematics — every feature is backed by published, verifiable math.
