pub struct BlockchainProvider<N: NodeTypesWithDB> { /* private fields */ }
Expand description

The main type for interacting with the blockchain.

This type serves as the main entry point for interacting with the blockchain and provides data from database storage and from the blockchain tree (pending state etc.) It is a simple wrapper type that holds an instance of the database and the blockchain tree.
