The MapStore is a simple interface used by the SM(S)T to store, delete and
retrieve key-value pairs. It is intentionally simple and minimalistic so as to
enable different key-value engines to implement and back the trie database.
See: the interface for a more detailed description of the simple interface required by the SM(S)T.
simplemap is a simple kv-store shipped with the SM(S)T. The SMT library that
can be used without it as long as the selected node store adheres to the
Mapstore interface.
This library is recommended for development, testing and exploration purposes.
This library SHOULD NOT be used in production.
See simplemap.go for more details.
This library provides a wrapper around [dgraph-io/badger][https://github.com/dgraph-io/badger] to adhere to
the MapStore interface. See the full documentation for
additional functionality and implementation details.
See: badger for more details on the implementation of this submodule.
Any key-value store used by the tries should not be able to be externally writeable in production. This opens the possibility to attacks where the writer can modify the trie database and prove values that were not inserted.
