- IOTAS certification tool can now be used and offers two different certification levels.
- The blocking mode certifies permanent records such as contracts, while the dynamic mode, for example, certifies transaction data.
IOTA has an open source toolkit called “Notarization Alpha” introducedwhich is now available in the Mainnet. This enables customers to demonstrate counterfeiting records. The tool kit is suitable for use in a variety of industries in which a reliable data check is desired without additional complicated process.
The method of blocked certification is intended for permanent documents that require strict integrity, such as contracts or compliance documents. The data is irrevocably saved on the chain and can optionally be provided with a time lock, so that a change or deletion is not possible during the duration of the lock. It is suitable for organizations in which the durability and unchangeability of documents is particularly important.
In contrast, dynamic certification for applications is intended for which updates are required in real time. This includes applications such as tracking products or digital IDs, in which only one changeable entity is kept in the chain throughout. Their flexibility enables work processes based on constantly changing data without the original proof of authenticity being lost.

Proof and validation now completely onchain
The process is designed in such a way that both developers and companies can check the integrity of data using Rust or Wasm libraries or by smart contracts created with the move language. This simplifies the integration for a number of organizations that want to integrate safe, verifiable data processing into their work processes.
The data review system follows a clear event chain. First, the user – or “prover” – puts the data or their hash into the chain. Then a clear object is generated with a identifier that is returned to the auditor. This identifier is sent together with the original data to the “Verifier”, which calls for the data from the ledger and checks metadata such as version, time stamp and owner. The last step is to check whether the data matched what was recorded.
This new process offers companies a practical way to check the integrity of their data without having to rely on central systems. The verifier can work with the same SDKs and smart contracts to confirm whether the certification is valid. If there is a agreement, the data is considered confirmed and forgery.
IOTA Rebased starts after years of development
In the previous article we mentioned that Iota has completed two important changes by the end of the second quarter of 2025. First of all, the Mainset was successfully switched to a new generation of the Layer 1 blockchain, which is known as IOTA Rebased. This change took place after more than a year of concentrated development and has now opened the door to greater scalability and performance improvements for all applications.
Second, when founding the Twin Foundation, Iota helped to promote the innovation of digital trade protocols on a global level. With the commissioning of Twin and the newly attached Mainnet, Iota laid the foundation for a new infrastructure that is tailored to logistics and digital trade.
According to the project team “The alpha version of IOTA notarization, which can be checked in the hands of builders” This framework could pave the way for real applications that need safe and comprehensible records without excessive complication.
