Overview

Package remotedb implements the key-value database layer based on a remote geth node. Under the hood, it utilises the `debug_dbGet` method to implement a read-only database. There really are no guarantees in this database, since the local geth does not exclusive access, but it can be used for basic diagnostics of a remote node.
