Lottery and block chains are very compatible and can be expected to develop business. For business partners, there is a major accounting firm to support the transparency of this project. Cheers to their challenge to transparency!
Transparency is really critical in this type of business. If people find out that there's manipulation going on, their trust can't be brought back. So this project needs to be transparent all the time to gain that trust from its users. They can build that image thru time. It's not an overnight process.
