state

Documentation

Overview

Package state provides a structure for celestia-node's ability to access state-relevant information from as well as submit transactions/messages to the celestia network.

This package contains one main interface, `Accessor`, that defines the methods available for both accessing and updating state on the celestia network.

`Accessor` will contain three different implementations:

1. Implementation over a gRPC connection with a celestia-core node called `CoreAccess`.
2. Implementation over a libp2p stream with a state-providing node.
3. Implementation over a local running instance of the celestia-application (this feature will be implemented in *Full* nodes).
