Crate zcash_client_sqlite

An SQLite-based Zcash light client.

zcash_client_backend contains a set of APIs that collectively implement an SQLite-based light client for the Zcash network.

Design

The light client is built around two SQLite databases:

• A cache database, used to inform the light client about new CompactBlocks. It is read-only within all light client APIs except for init_cache_database which can be used to initialize the database.

• A data database, where the light client's state is stored. It is read-write within the light client APIs, and assumed to be read-only outside these APIs. Callers MUST NOT write to the database without using these APIs. Callers MAY read the database directly in order to extract information for display to users.
