Shigeru and Hiroki made the presentation about the mechanism of blockchain and its potential related to web-based content distribution. They also showed the demonstration about contents use control via blockchain. And then, started the open discussion. In this discussion, main topic was business model, that is, what is incentive to continue maintaining blockchain in this case. The result of this discussion is that blockchain application is very brand-new topic and a community group would be adequate because better understanding is required.
