Anchor Your Data with IOTA Notarization
Flexible, Tamper-Proof Records on IOTA
TL;DR:
Businesses rely on accurate records every day: supply chains demand precise tracking, certifications must be verifiable, and regulators require immutable audit trails. But traditional systems are often brittle. Centralized databases can be altered, lost, or tampered with – exposing organizations to costly errors and fraud.
In fact, document-related fraud alone costs organizations an estimated 5% of their annual revenues, amounting to billions of dollars each year. Whether it’s falsified invoices, manipulated credentials, or unauthorized changes to contracts, the financial and reputational risks are real.
IOTA isn’t here to replace these systems, but to complement them with an added layer of trust. Centralized solutions, whether on-premise or cloud-based, are essential for operational efficiency, internal workflows, and private data management. But when it comes to sharing trustworthy information across organizational boundaries, especially in large, multi-stakeholder ecosystems, traditional systems fall short.
This is where IOTA Notarizationcomes in.
Instead of relying on a single point of control, it enables the creation of decentralized, tamper-proof records that guarantee data authenticity and integrity. Businesses and private individuals can anchor critical information securely, confident that their data remains precisely as intended – verifiable by anyone, alterable by no one.
What Is IOTA Notarization?
IOTA Notarization is an open-source, modular toolkit for recording and verifying the integrity of data on the IOTA network. Whether you're building for compliance, traceability, or auditability, this product helps you anchor trust into your workflows in a way that makes sense for your use case.
It’s important to note that notarization does not mean storing entire documents on a public blockchain network. In most cases, you should only anchor a digital fingerprint (a cryptographic hash) of your data or document. The original file stays in your existing, private storage system, while the public ledger serves as an immutable proof of its existence and integrity over time.
This release introduces two notarization methods, each tailored to different business requirements:
Locked Notarization: For mission-critical, permanent records like certificates or contracts, Locked Notarization stores data immutably on-chain, with an optional time-lock that prevents changes or deletion for a defined period.
Dynamic Notarization: When real-time updates matter most, like product status updates or digital passports, Dynamic Notarization maintains a single, updatable object on-chain.
IOTA Notarization is built for developers, builders and organizations looking to integrate blockchain-based data authenticity and integrity proofs into their products. Whether you’re aiming for compliance, tracking, or verifiable records, IOTA Notarization provides ready-to-integrate tooling that can support operations across many industries:
Locked Notarization:
Dynamic Notarization:
Regardless of the use case or the sector, we strongly recommend anchoring digital fingerprints (hashes) of sensitive documents – not the documents themselves – unless public visibility is explicitly desired. This ensures data integrity without compromising confidentiality.
How Does it Work?
You can integrate IOTA Notarization using Rust, WASM libraries, or directly with the Move-based smart contracts. Here’s how it works from start to finish – from anchoring data to verifying its integrity.
Key Concepts
1. Prover stores data on-chain: The Prover submits a transaction with the Stored Data – either the full Original Data or just its hash – depending on confidentiality requirements.
2. Notarized object is created: The ledger creates a new Notarized Object and returns a unique Identifier (Object ID) to the Prover.
3. Prover shares Identifier and data: The Prover shares the Identifier along with the Original Data (or its hash) with the Verifier.
4. Verifier queries the ledger: The Verifier uses the Identifier to retrieve the notarized object via the Rust/WASM SDK or Move smart contracts.
5. Verifier checks metadata: Before comparing data, the Verifier inspects metadata like the creation timestamp, owner, and version to confirm context.
6. Verifier validates integrity: The Verifier compares the on-chain Stored Data with the provided Original Data or its hash. If they match, the notarization is confirmed as valid and tamper-proof.
Data Visibility Considerations
When using IOTA Notarization, it's crucial to understand that all notarized information becomes public on the IOTA network, and is thus visible and verifiable by anyone. This transparency is the very point of notarization on a public distributed ledger and ensures integrity, immutability, and verifiability through high availability of certain information.
Depending on your confidentiality needs, IOTA Notarization leaves you all the flexibility you need to implement different approaches:
Always carefully evaluate your privacy requirements before using IOTA Notarization. Public ledgers guarantee data integrity – not privacy.
Get Started
Stamped and Sealed: IOTA Notarization
Notarization is one of the most universally applicable blockchain use cases. Simple in concept and powerful in practice, the IOTA Notarization alpha release puts verifiable trust in the hands of builders. It offers flexible tools to store, update, and verify data according to real-world requirements. Whether you need permanent records or dynamic updates, IOTA provides the scalability and precision to anchor your data your way.
