Lava Network. Installing the node

Lava is the first modular network for blockchain access that introduces a new approach: "specifications" is a primitive that allows participants to add support for new chains and data services to the underlying protocol without permissions. RPC is the network's first supported service. Developers integrate Lava into their projects to retrieve data, and network node operators are motivated to respond quickly, accurately, and reliably. Lava creates a fast, scalable, and unified network for accessing a multi-networked world.
