Drawing numbers is the most important but also most critical process in all lotteries and games of chance. The players must be able to trust the integrity of this process. Although manual draws using lottery machines guarantee the requisite transparency, they are cost-intensive and not suitable for lotteries with frequent draws. Electronic Draw Systems have been available on the market for a number of years now, but so far they have failed to comply with some key principles: they are often not transparent, have security flaws or provide unverifiable results, which can undermine public trust in the system.
The perfect seed thanks to blockchain technology
In adessoDraws, the lottery experts at IT service provider adesso have developed an innovative system that meets all requirements: unpredictability, transparency, non-repudiation, understandability, replicability and auditability. What’s more, thanks to its use of blockchain technology and an open source algorithm as a random number generator (RNG), adessoDraws is completely transparent and secure. Every draw is audit-proof, as each stage of the draw is documented.
