Sedicii - Lead Crypto Mathematician

Sedicii is an award-winning company focused on confidential collaborative computing without sharing sensitive information but still achieving a joint outcome. It does this using a number of advanced and distributed technologies to capture, compare and validate and calculate results. To support this, it is creating a federated, global identity verification network which enables real-time identity verification by certified, trusted identity providers (governments, banks, telco’s, utilities), ensuring that businesses can react quickly to new government, regulatory and industry demands for real-time identity verification, authentication and trust services. The company develops software as a KYC, AML service for the identification and authentication of people, vehicles, products and other physical and virtual goods and services. Included in our identity network are enabling products including authentication software, a KYB and KYC Onboarding solution (the only of its kind!) and AML Monitoring and Payment Pre-execution software. Government and different industry sector organisations are starting to use these for yet more use cases in supply chains, border controls, health, aviation, maritime, logistics and more.
