DATA Network plans to retire its chain and move to Sui

Sui Foundation and DATA Foundation announced on October 12 that DATA Network will stop operating as an independent blockchain and move its protocol to Sui, with Sui’s Walrus system becoming the default storage layer for applications run by DATA Foundation.

The change is consequential because it replaces a standalone network with an application protocol dependent on another base layer. But it is a migration plan, not a completed shutdown. The existing DATA Network will continue operating until the upgrade is finished, and the foundations have not published a transition date.

The token is meant to move with the protocol

The primary announcement says the DATA token will carry over to Sui on a one-to-one basis. Locked and vesting positions are intended to retain their existing schedules, while holder economics and governance rights are promised to be at least equivalent to their current form.

Those commitments define the intended transition, but they do not yet establish its execution. The announcement does not identify a token-contract address on Sui, a snapshot block, an exchange-support plan, a bridge procedure or a final date for retiring the old chain. DATA Foundation said a detailed timeline and holder transition plan would be released before the upgrade.

Walrus is also described as becoming the default storage layer for DATA Foundation applications. That would separate roles across the stack: Sui would supply transaction execution, while Walrus would store files and enforce access conditions around them. The partners say encrypted source files can be tied to provenance records so later processing can be checked against the original. The source material does not show that this full workflow is already in production.

A $30 million investment accompanies the move

Sui Foundation said it is investing $30 million in DATA Network and would become its largest institutional holder, alongside PIP Labs and DATA Foundation. The Block independently reported the amount and structure from a statement supplied by DATA Foundation, while Cointelegraph reported that a foundation representative characterized the investment as a separate part of the broader partnership.

The $30 million figure is therefore an announced investment amount as of October 12. The public materials reviewed do not disclose the instrument, valuation, closing conditions, payment schedule, token price or amount of DATA acquired. It should not be read as cash already transferred, protocol revenue, user deposits, total value locked or a market valuation.

Cointelegraph also reported DATA Foundation’s explanation that maintaining validators, network security and infrastructure for a single-purpose chain carried costs that could be avoided by using Sui, Walrus and related tools. That is the foundation’s rationale, not an independently measured cost comparison.

Provenance claims still require outside proof

DATA Network’s Trace registry records the stated origin and usage rights of AI training data and arranges payment to contributors. Moving that registry to Sui may simplify infrastructure, but a blockchain entry can prove that information was recorded at a particular point; it cannot by itself prove that a contributor owned every right claimed, that consent remained valid or that a dataset complied with every jurisdiction’s law.

The primary announcement describes Trace data as rights-cleared and says applications already license it to AI and robotics companies. Coinburn found no independent audit in the source packet establishing the completeness of those rights, the identity of all buyers or the accuracy of every registry entry. Those statements should remain attributed to the foundations.

The next verifiable milestones are the transition plan, deployed Sui contracts, token-migration mechanics, an old-chain cutoff and evidence that Walrus stores the promised reference files. Until those arrive, the defensible conclusion is narrow: DATA Network has chosen to retire its chain and migrate, backed by an announced Sui Foundation investment, but the operational handoff has not happened.
