kaspad/database

database

Package database provides a block and metadata storage database.

Please note that this package is intended to enable kaspad to support different database backends and is not something that a client can directly access as only one entity can have the database open at a time (for most database backends), and that entity will be kaspad.

When a client wants programmatic access to the data provided by kaspad, they'll likely want to use the rpcclient package which makes use of the JSON-RPC API.

The default backend, ffldb, has a strong focus on speed, efficiency, and robustness. It makes use of leveldb for the metadata, flat files for block storage, and strict checksums in key areas to ensure data integrity.
