This repository contains the IOTA Notarization Toolkit, a set of IOTA ledger tools for verifiable on-chain data workflows.
The toolkit includes:
- Single Notarization Use this for individual locked or dynamic notarizations of arbitrary data, documents, hashes, or latest-state records.
- Audit Trails Use this for structured record histories with sequential entries, role-based access control, locking, and tagging.
- Proof of Inclusion Use this to construct portable cryptographic evidence that a transaction, event, or object state is included in a certified IOTA checkpoint, and to verify that evidence locally.
Use Single Notarization for one on-chain object that stores arbitrary data, a document hash, or the latest state of a record.
Use Audit Trails for structured record histories with permissions, capabilities, tagging, and write or delete controls.
Use Proof of Inclusion when a verifier needs portable evidence that a transaction, event, or object state is included in a certified checkpoint. Proof of Inclusion verifies existing ledger activity and does not define a separate on-chain object or Move Package.
Single Notarization and Audit Trails provide on-chain contracts:
