Nnadozie Onyeukwu.

I have been building things since my days at FUT Owerri, where we launched the university’s first campus FM radio station. In industry, I served as a global lead ASIC design engineer, helping to develop the inertial sensors used in the early versions of the iPhone. I also invented a wafer-level chip-scale packaging technology for inertial sensors. Till today, the US Government has continued to honour royalties for using my PhD research and the patent that came out of it. I am a Nigerian and I build things! Good People, when we engineered a native blockchain for Contisx Securities Exchange, we saw an opportunity to extend that operating system into a new category of secure communication. That vision led us to build the Contisx Phone, a cryptographically secured blockchain phone designed to deliver superior communication security for individuals, companies and governments. Yes, blockchain-secured with absolute sovereignty.
