Proof bundles

A proof bundle is a zip containing everything needed to verify an

anchor offline. Download via the link on /anchors/[id] or via

GET /api/anchors/[id]/bundle.zip.

Contents

• manifest.json: the v2 envelope and metadata
• payload.json: the atom payload
• signing-keys/: PEM-encoded public keys used in the chain
• chain-receipts/: structured receipts from Polygon and nebulad
• verify.sh: a shell script that runs the verifier CLI

Use

The bundle is self-contained. Run ./verify.sh or call the CLI:

nebula-verify check ./manifest.json

A green line means both chains agree and the signing-key chain

checks out. A red line means the proof failed; the message says

which chain disagreed and how.
