The **Archiver Discovery** library lets Shardeum node software (consensus, explorer, gateway, archiver, etc.) automatically locate and query archiver nodes. It aggregates archiver addresses from an environment variable, a local config.json, and a remote JSON file, merges and shuffles them, and provides utilities (e.g., `setupArchiverDiscovery` and `getFromArchiver`) to initialize the list and fetch data securely. It’s intended for developers building or configuring any Shardeum node that needs reliable access to archiver services.
