Client backend that is backed by a database.
Finality indicates that a block will not be reverted, according to the consensus algorithm, while canonicality indicates that the block may be reverted, but we will be unable to do so, having discarded heavy state that will allow a chain reorganization.
Finality implies canonicality but not vice-versa.
State backend that's useful for benchmarking
RocksDB-based light client blockchain storage.
RocksDB-based offchain workers local storage.
A reference tracking state.
Where to find the database..
Hash type that this backend uses for the database.
DB-backed patricia trie state, transaction type is an overlay of changes to commit.
