The eXpandable AI Network



We use the strengths of modern machine learning algorithms, particularly reinforcement learning, to stabilize our own Ethereum-based low-energy Blockchain. This enables an enterprise-ready, robust and adaptable infrastructure for automated business processes. Using our XAIN infrastructure for top-level applications and solution services, our partners are enabled to build privacy friendly and highly secure environments to prepare for a strong competitive positioning in an automation focused future.
