Before kickoff it publishes a SHA-256 fingerprint of that matchday's model calls. The calls stay hidden. After full-time the same canonical payload is revealed so anyone can recompute the digest.</p> <p>A screenshot of a winning slip can be made after the whistle. A hash published on a clock ThesisBet does not control cannot be edited afterwards without breaking.</p> <h2> Morning fingerprint </h2> <p>Each call is reduced to match id, market, selection, strength, and a rate to one decimal. The list is sorted, serialised as compact JSON, and hashed with SHA-256. That digest is printed on <a href="https://thesisbet.com/verify" rel="noopener noreferrer">https://thesisbet.com/verify</a> and the dated page, e.g. <a href="https://thesisbet.com/verify/2026-08-17" rel="noopener noreferrer">https://thesisbet.com/verify/2026-08-17</a>, and posted on X.</p> <h2> Independent clock </h2> <p>The X timestamp is the clock ThesisBet does not operate. The post is the digest, not the selections.</p> <h2> Reveal </h2> <p>After the matchday ends, the dated verify page shows the committed payload next to the same fingerprint. Render-time fixture names and won/lost labels are not part of the hash input.</p> <p><a href="https://thesisbet.com/calls" rel="noopener noreferrer">https://thesisbet.com/calls</a> ("Perfect Calls") is a filter: only fixtures where every sealed call won. It is not the full record.
