Case study

Challenge

A lottery platform lives on trust: participants must be sure the draw is fair and cannot be manipulated by the organizer.

Approach

A provably fair system: cryptographically sealed participant lists (SHA256 + JSON signatures), Random.org-powered draws, and a transparent mechanism where the last ticket bought triggers the draw.

Results

Live at tombolescu.ro with verifiable draws and sealed lists — trust through technical transparency, not promises.
