Trace Registry

Sui Foundation is deploying $30 million to absorb DATA Network and its Trace registry, migrating a live supply of 250 million rights-cleared AI training data receipts onto Sui and Walrus infrastructure. The move positions Sui as the primary settlement layer for consented, auditable data licensing to frontier AI labs, a use case regulators now demand under the EU AI Act.

• Trace registry has recorded 250 million verifiable AI training data contributions since June launch, processing 3 million receipts daily on average.
• Sui Foundation is investing $30 million to establish the largest institutional stake in DATA Network alongside PIP Labs and DATA Foundation holdings.
• DATA Network will migrate from independent chain to run natively as a Sui protocol, with $DATA token carried over one-to-one and Walrus as default storage layer.

• 250M Verifiable AI training data receipts recorded by Trace since launch.
• 3M Average daily receipts processed by Trace registry on current network.
• $30M Sui Foundation investment establishing largest strategic stake in DATA protocol.

The Sui Foundation and DATA Foundation announced the integration of DATA Network and its Trace registry into the Sui stack, moving a live supply of consent-verified training data onto Sui and Walrus infrastructure to serve frontier AI labs. Trace, launched in June as an onchain registry for AI training data, records the origin and licensing rights of each contribution and settles payment to the originating person. The registry currently tracks more than 250 million contributions and processes an average of 3 million receipts per day. Applications already writing to Trace include Kled, which has 1.5 billion human-generated records in onboarding, plus Numo and Oto, both of which license data to AI labs and robotics firms. The upgrade addresses a structural constraint in generative AI: open-internet training data has been exhausted, and the next frontier requires personal data obtained with explicit consent and audit-ready provenance that regulators and legal teams will accept.

Sui Foundation backs $30 million strategic stake as largest DATA Network holder

Sui Foundation is investing $30 million in DATA Network, establishing the largest institutional stake in the protocol alongside existing holdings by PIP Labs and DATA Foundation. The capital commitment is tied to a protocol upgrade that will retire DATA Network’s independent chain and migrate the network to run natively on Sui, with the $DATA token carried over one-to-one and all locked and vesting positions remaining unchanged. SY Lee, Chairman of Poseidon and CEO of PIP Labs, is joining Sui Foundation as a Strategic Advisor to guide the integration.

The move consolidates AI data infrastructure around a single settlement layer. Adeniyi Abiodun, Co-Founder and Chief Product Officer at Mysten Labs, the core contributor to Sui and Walrus, said: “Sui and Walrus were built to be the home where AI data is stored, licensed, and paid for, capable of operating at the scale these systems demand.

The migration of DATA Network and Trace to our stack now brings massive volumes of high-quality, rights-cleared data that is already serving the world’s frontier AI labs.”

The AI industry has reached the point where the open internet has been read, and the next frontier is defined by access to datasets with the consent and provenance that regulators require.

Walrus encryption and immutable file storage replaces metadata-only provenance

Currently, a Trace record proves only that a file was registered and when. After integration with Walrus, the data platform built on Sui for encrypted storage and access control, Trace will hold an encrypted, immutable copy of the contributed file itself as a reference guarantee.

This shift from metadata-only receipts to cryptographic file verification means the hash of the record can be regenerated from the data itself rather than from metadata supplied by an application, and any downstream processing of the file can be checked against the original. The result is tamper evidence and stronger provenance guarantees aligned with regulatory audit requirements.

Walrus becomes the default storage layer for all DATA Foundation applications. Andrea Muttoni, CEO of DATA Foundation, stated: “Making sure data is traceable, auditable and cleared to use is just as important for AI safety as it is a precursor for data quality. With Trace, we have been tracking hundreds of millions of data assets.

Joining forces with Sui now allows us to build out more of the stack, like encrypted reference file storage and potentially fully verifiable TEEs for evals and fine tunings in the future.” The statement signals potential expansion beyond current provenance tracking to include trusted execution environments for model evaluation and fine-tuning, a capability not yet live.

Migration timeline and token transition details still pending before upgrade launch

The existing DATA Network will continue operating until the upgrade is complete. A detailed timeline and holder transition plan will be published prior to the migration, but neither document has been released as of October 12.

The announcement does not specify a target date for the protocol upgrade or a deadline for token holders to migrate positions, creating uncertainty around when Trace receipts will begin settling on Sui’s native infrastructure rather than DATA Network’s independent chain.

The integration also leaves one structural question unresolved: whether AI labs currently licensing data from Trace will automatically gain settlement and storage on Sui, or whether they will need to update licensing agreements or integrate new wallet infrastructure to access the migrated data.

Kled, Numo, and Oto all operate applications on Trace; clarification of their migration path will be key to validating whether the upgrade accelerates adoption or introduces friction for existing customers.

The CCS read. We see this as a consolidation play by Sui Foundation, not a data supply breakthrough. The 250 million Trace receipts are real, but Sui’s stake is about locking AI data infrastructure to its Layer 1 before other chains do so at scale. Token holders get one-to-one carryover and governance preservation; what matters for institutional adoption is whether Kled and the AI labs can settle faster and cheaper on Sui than they can today, and whether Walrus encryption actually closes the legal provenance gaps that regulators are now demanding.

Watch for the detailed migration timeline and holder transition plan, which DATA Foundation and Sui Foundation said will be published prior to the protocol upgrade but have not yet released. That document will clarify the target date for retiring DATA Network’s independent chain, the mechanics of $DATA token transfer to Sui, and whether existing Trace data licensees will need to reintegrate with new wallet or settlement infrastructure, details that will determine whether the integration runs smoothly or creates a window for competing chains to recruit AI data applications during the transition.
