Why Lasp?

Lasp is a new programming model designed to simplify large scale, fault-tolerant, distributed programming. It leverages ideas from distributed dataflow extended with convergent replicated data types, or CRDTs. This supports computations where not all participants are online together at a given moment. The initial design supports synchronization-free programming by combining CRDTs together with primitives for composing them inspired by functional programming. This lets us write long-lived fault-tolerant distributed applications, including ones with nonmonotonic behavior, in a functional paradigm.
