Contests run on the platform can have different look, rules and mechanics, but they all will be built on the blockchain-based backend module. This will ensure accountability of the organizers to the community especially in regard with prizes distribution.
Case study: a singer ‘Enrique’ releases a new album and needs to engage his fan base. He launches a global contest with hundreds of prizes for participants, incl. participation in real-life events. The community trusts the results.
