IOTA Notarization: Building Trustworthy and Tamper-Proof Data Proofs

In this course, we will learn about the Notarization module of the IOTA Trust Framework, from its concept and Move model design to SDK usage and real-world application examples, demonstrating how the IOTA Notarization Framework can be implemented in fields such as digital identity, legal technology, and the circular economy.

What You’ll Learn

Notarization Lifecycle Management: Master the Minting, Versioning (Update), Ownership Transfer, and Deposit Recovery (Destroy) of notarized objects.

Physical-Level Permission Locks (TimeLock): Apply UpdateLock, DeleteLock, and TransferLock to implement “code is law” constraint logic.

Dual-Mode Architecture Selection: Flexibly switch between Locked (Static Archiving) and Dynamic (Dynamic Evolution) modes based on business scenarios.

SDK Engineering Practice: Implement a closed-loop workflow based on TypeScript for generating digests from off-chain data, anchoring fingerprints on-chain, and performing fully automated asynchronous verification.

Syllabus

Unit 1 - Data Trust Crisis in the Real World

In this unit, we will expose the fatal flaws in traditional data management and see how IOTA defines digital truth.

Unit 2 - Core Concepts of IOTA Notarization

In this unit, we will learn about locked and dynamic Notarization and clarify "who is proving" and "what is being proven".

Unit 3 - On-Chain Data Models and Structures

In this unit, we will delve into the Move resource model and learn how to efficiently and securely build notarized data structures.

Unit 4 - Notarization SDK Walkthrough

In this unit, we will implement full lifecycle notarization of data using concise code.

Unit 5 - Application Scenarios of IOTA Notarization

In this unit, we will explore how Notarization breathes credibility into real-world assets, from the factory to recycling.
