Verify a Draw
Search by draw ID, lottery ID or ticket number. We recompute the frozen dataset hash, the randomization commitment and the verification hash from published data — you can repeat these SHA-256 computations yourself.
How verification works
1. Before the draw, all eligible ticket numbers are sorted, joined and hashed with SHA-256 — that is the dataset hash.
2. A random server seed is generated and committed as SHA-256(seed | dataset hash) before the winner is selected.
3. The winner is selected from the frozen dataset using a cryptographically secure random generator.
4. After the draw, the seed is revealed and the verification hash binds the draw ID, dataset, commitment, seed, results and timestamp together. Any change to any of these values breaks the hash.
