CRK, Bundles, Checksums, and Sync Queue

What is CRK, Bundles, Checksums, and Sync Queue?

Portable node replication and tamper-evident offline transfer. This guide covers when to use it, the best first action, best practices, common mistakes, and concrete next steps.

Content

Purpose

CRK view handles kit tiers, export/import bundles, SHA-256 checksum validation, cryptographic receipts, and the live offline sync queue.

When to Use

• Before moving data by USB
• After completing major interventions
• When flushing queued Nostr sync events
• When cloning or teaching another node

Best First Action

Export a bundle after a meaningful work session, then verify the checksum on import at the receiving node.

Best Practices

• Do not import bundles with failed checksums.
• Keep Nostr disabled until you intend to publish.
• Use owned keys in production, not ephemeral localStorage keys.
• Record receipts in History.

Common Mistakes

• Assuming export equals backup if the file is never copied off-device.
• Clearing the sync queue before confirming receipt.
• Treating one relay publish as durable federation.

Next Steps

• Flush queue when connected.
• Review Cryptographic Intake Ledger.
• Print or export knowledge-base guides with the bundle.
