Participated in the 2nd Virtual Currency "Janai!" Blockchain App Contest

Developed a lottery lottery "Fair lottery" that can secure fairness even if many people gather

No. 3 Solutions Co., Ltd. (Location: Meguro-ku, Tokyo, Representative Director: Tetsuo Omura, hereinafter referred to as our company), which is engaged in the blockchain development business, said on March 26, "Virtual currency "Janai! Blockchain application contest" ( I participated in the following contest).


The contest is open to companies and individuals who are members of the Blockchain Promotion Association (Representative Director: Asteria Co., Ltd., President and Representative Director Yoichiro Hirano, BCCC). Companies and individuals will develop apps that can be used in various industries and experience blockchain, rather than systems that are an extension of crypto assets (virtual currencies), and announce at the contest. The first App Contest was held on May 1, 2018, and this is the second time it has been held.


The app announced at the app contest is "Fair lottery"

We have developed a combination of cash server and blockchain technology (patent pending) so that lottery lottery held at ticket sales and shopping malls can be done smoothly and fairly.


"Fair lottery" has two characteristics. The first is to be able to smoothly draw lots of people. At the moment, lottery lottery held at shopping malls, etc., has more customers than expected, and we are unable to distribute lottery rights. It takes time and effort for the store side to secure staff members. In addition, when using a system, a considerable cost will be required for capital investment such as system construction.

Second, the lottery results cannot be manipulated even by the management. In the case of a lottery, I think some people think that the person making the selection is doing something. By utilizing the blockchain, we have realized a mechanism in which neither the management side nor the participants know the result until the timing of the judgment.


By utilizing blockchain technology in this way, we were able to develop a lottery app that can be implemented smoothly and at low cost even for large-scale campaigns, and that can maintain fairness in lottery.

Unfortunately, we were not able to win the award in this contest, but we will continue to prepare for the development and release of a new blockchain service.


At BCCC, we are working on the idea that blockchain technology can be not only cryptographic assets but also basic technology for information sharing and information exchange in various industries. BCCC member companies include not only financial companies but companies of various industries.


We are developing blockchain technology in fields that are not crypto assets. We are applying for patents for three technologies that take advantage of the characteristics of blockchain.
