CRYPTographic draw integrity

Provably fair.
Verifiable by anyone.

The secret is committed before the draw. After settlement, it is revealed so the exact winning ticket can be independently reproduced.

01 · BEFORE DRAW

Seed commitment

A fresh 256-bit secret is generated. Only its SHA-256 commitment is published, preventing the seed from being changed after entries arrive.

02 · AT DRAW

Deterministic result

SHA-256 hashes the revealed seed, epoch, final ordered ticket manifest, and nonce into one immutable draw digest.

03 · AFTER DRAW

Independent verification

The seed and complete proof are revealed. Rejection sampling maps the digest to a ticket with zero modulo bias.

The resulting 256-bit integer selects one ticket from the exact final ticket count. Values outside the largest evenly divisible range are re-hashed with the next nonce, eliminating modulo bias.
