Mobile network operators face challenges with outdated billing and contracting systems that make it difficult to launch new products and lead to customer service issues. DIADEM seeks to address this by developing a blockchain network using decentralized smart contracts to handle billing, payments, and contracting. This would allow operators to quickly launch new offerings and give customers real-time billing access and clarity on charges through a mobile app. The project is led by an experienced team aiming to disrupt the telecom industry through this innovative solution.
