Working on blockchain design for 3 years. Designed bitbill bitcoin wallet and Binance new version. Now I am working on ONT Ontology and OnTrade Crypto Exchange (OnTrade.com new version 2.0 white design, Beta url: http://ontrade.v2.cform.cn). I participated in the Authenticator project a few weeks ago. It is a very simple decentralized identity tool, which will be demonstrated at the development conference this month. Currently only Android version is supported.
