Cyphersolver — Unsolved Historical Ciphers: an open ledger of decipherments, contributors and corrections
A shared ledger of historical ciphers nobody had read, drawn from Tomokiyo's catalogue, Elonka Dunin's famous unsolved codes, Schmeh's Top 50 and the contributors: what has been deciphered, by whom and how, with new decipherments by a frontier AI (Claude) and by contributors, corrections where a solution already existed in print, and a record of where and why each attempt stops. Anyone can contribute a solution, a new cipher or a check.
