State-Management

Introduction Orchestrating dozens, hundreds, or even thousands of autonomous agents—whether they are micro‑services, IoT devices, trading bots, or fleets of drones—requires a distributed state management layer that is both fast and reliable. In a traditional monolith, a single database can serve as the single source of truth. In a multi‑agent ecosystem, however, the state is continuously mutated by many actors operating in parallel, often across geographic regions and unreliable networks. ...

In many of these domains, a distributed multi‑agent system (MAS) is the natural way to model autonomous decision makers that must cooperate, compete, and adapt to a shared environment. ...
