Conflict-Free Replicated Data Types (CRDTs) are a mathematical solution designed to ensure data consistency across devices in environments where connectivity is unreliable, such as retail, healthcare, logistics, and manufacturing. CRDTs allow applications to function offline without merge conflicts by enabling data to sync predictably once connectivity is restored. Ditto utilizes CRDTs in its distributed database platform to facilitate real-time peer-to-peer sync among devices like mobile phones and IoT sensors, forming mesh networks that do not require a central server. This approach provides automatic conflict resolution and continuous productivity, even with spotty connectivity, by ensuring all updates merge consistently. CRDTs offer a significant advantage over traditional distributed systems by eliminating the need for central coordination and manual conflict resolution, thus enhancing the reliability and scalability of applications at the edge. In edge environments, CRDTs ensure that operations converge correctly, allowing devices to update data offline and trust that their state will align with others once reconnected, transforming data flow reliably and securely.

Ditto's acquisition of KeySquare Labs (KSL) and its Software Defined Networking (SDN) platform, Propagate, enables Commercial Off The Shelf (COTS) Android devices to support military, first-responder, and public safety data-sharing applications such as the Android Team Awareness Kit (ATAK). Propagate transforms any Android device into a tactical edge network hub, facilitating secure interconnections with military radios and tactical appliances, and offering functionalities like edge network routing, terrestrial-cloud gateway, and network interface control. This shift from custom, costly Android End User Devices (EUDs) to commoditized hardware reduces costs, enhances security, and accelerates the deployment of new capabilities, addressing previous limitations associated with custom EUDs. Propagate's approach leverages the Android device's user space for networking functions, reducing reliance on custom kernel modifications and aligning with existing USG programs for classified use. This transformation fosters a more resilient, flexible, and cost-effective networking solution for military and public sector applications, highlighting a move towards commoditized, software-defined networking technologies.
