If you are fond of either Intellectual Property or Innovations, Kakushin Ecosystem is the one for you. An open source distributed ledger framework for Intellectual Property Rights Management, upon which users can search, register and sort specific patent applications and inventions. Using hyperledger as an IP registry may give clarity to copyright innovators and users. The Kakushin's Hyperledger based IP management will verify the uniqueness of idea/concept with tamper-proof evidence of ownership and that I think what makes Kakushin different from all the other ICOs. This one is a "must buy".
