    ) -> Result<Option<LocalKeyType>, DKGError>;

A Database backend, specifically for the DKG to store and load important state

The backend of this database could be using a persistence store or in-memory ephemeral store, depending on the use case. For example, during the tests we can switch to an in-memory store, and in production we could use sled database or Offchain storage.

Required Methods

fn get_local_key( &self, session_id: SessionId ) -> Result<Option<LocalKeyType>, DKGError>

Returns the DKG [LocalKey<Secp256k1>] at specific session, if any.

fn store_local_key( &self, session_id: SessionId, local_key: LocalKeyType ) -> Result<(), DKGError>

Stores the [LocalKey<Secp256k1>] at a specified session.
