+// 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).
