Blockchain-based Approachs for High Secure P2P-type Decentralized Cloud Storage and Practical Smart Contract for Trading Personal Data
update:2020-06-16
Features
We are developing a decentralized P2P (Peer to Peer) type cloud storage that realizes innovative level of security by use of surplus storages of P2P nodes with the Blockchain technology. The developed storage can avoid the risk of large-scale information leakage of stored data due to the weakness of the central server. By using our cryptographic currency for rewards and usage fees in the storage, fair storage usage of all users can also be achieved.In addition, We are developing a unique smart contract technology for practical decentralized trading of personal data among an unspecified number of users.
Targeted Application(s)/Industry
We hope to conduct collaborative researches with companies developing Bitcoin 2.0 type application (e.g. smart contract, Fintech) based on the Blockchain technology, the Internet of Things (IoT) technology, Medical Database for practical use.Researchers
