IOTA is seeing another example of real-world activity emerge from its digital identity infrastructure, with community data showing nearly 50,000 certificate notarizations recorded on the IOTA Mainnet over a four-week period.
According to data highlighted by Iota Feed, 49,720 notarizations were recorded between August 22 and September 19. The activity was associated with Turing Space, a digital identity company that joined the IOTA Business Innovation Program in November 2025.
The reported activity is notable because it provides an observable measure of blockchain usage following the partnership announcement. Rather than simply describing a planned application, the data points to certificates and credentials being anchored to the IOTA ledger through an operating platform.
Turing Space Brings Digital Certificates Onchain
Turing Space develops Turing Certs, a platform designed to issue, manage and verify digital credentials. IOTA introduced the company to its Business Innovation Program in November 2025, describing its focus as secure digital identities and verifiable credentials for institutions and enterprises.
IOTA said Turing Space had already worked with organizations including the World Health Organization to issue digital certificates to more than 12,000 volunteers across 150 countries. The company also helped verify more than 3.5 million renewable-energy certificates in Taiwan’s green-energy trading system.
The newer Mainnet activity gives that earlier background a different dimension. The community analysis identified 139 different issuer addresses, each associated with its own issuer decentralized identifier, or DID.

If that interpretation is correct, the structure could indicate that a single credential platform is serving multiple organizations rather than one institution generating all of the certificates. The addresses alone, however, do not independently establish the identities or business relationships of the issuers.
The reported transaction pattern also appears to involve periods of concentrated activity. Iota Feed said some days recorded more than 6,000 notarizations while other periods were relatively quiet, suggesting that certificates may be processed in batches rather than at a constant rate.
That type of activity fits the broader purpose of IOTA Notarization. The IOTA Foundation describes the product as infrastructure for anchoring and verifying data onchain, including credentials and certifications, while allowing sensitive information to remain offchain.
Privacy Becomes Part of the Blockchain Use Case
One of the more important aspects of the reported implementation is what does not need to be placed on the public ledger. IOTA’s documentation says its notarization system can store a digital fingerprint, or cryptographic hash, onchain while keeping the underlying information offchain.
For certificates containing personal or corporate information, this model can provide a way to prove that a document has not been altered without publishing the underlying details. A verifier can check the credential against its cryptographic proof without necessarily receiving every piece of information contained in the original record.
IOTA’s technology showcase describes Turing Space as a privacy-first credential platform where information can be selectively shared during verification. The company is also presented as using W3C-aligned credentials and IOTA infrastructure for cross-border verification.

The economic model is another reason Turing Space selected IOTA. Turing Space co-founder and CTO Henry Hang previously cited IOTA’s low transaction costs and sponsored transactions as important factors for making large-scale credential issuance affordable for end users.
The reported 49,720 notarizations therefore matter less as a standalone number than as evidence of the type of workload IOTA has been trying to attract through its Business Innovation Program. The program was explicitly designed around measurable Mainnet activity and real-world applications involving areas such as identity, compliance and data integrity.
There are still limits to what the available data proves. A notarization is evidence of an onchain record, but it does not by itself reveal how many people use the resulting credentials, the commercial value of the certificates or the revenue generated by Turing Space.
Still, the development gives IOTA users something more concrete to examine than a partnership announcement alone. If the community’s figures remain consistent with activity visible through the IOTA Explorer, Turing Space provides a measurable example of digital credentials being anchored to the Mainnet at scale.
