Trace Lands on Sui With 250M Receipts, Because the Open Web Is Tapped Out 📜

Palo Alto, United States, October 12th, 2026 — The DATA Network's Trace registry, an onchain ledger for rights-cleared AI training data, is integrating with the Sui stack and will make Walrus its default storage layer, according to an announcement from the Sui Foundation and The DATA Foundation. Walrus is the data platform that anchors integrity proofs on Sui, and the arrangement makes it the primary storage layer for applications operated by DATA Foundation. Separately, the DATA Network is being upgraded to run as a protocol natively on Sui.

Trace, launched by DATA Foundation in June as an onchain registry for AI training data, records the origin of each contribution and the rights attached to it and settles payment to the contributing individual. Since launch it has registered more than 250 million contributions and now processes over 3 million receipts per day on average. Applications writing to Trace include Kled, described as the largest opt-in human data marketplace with more than 1.5 billion records being onboarded, along with Numo and Oto, applications that already license data to frontier AI labs and robotics companies.

The Sui integration is designed to give AI labs a single venue to source real-world training data they are licensed to use, with provenance recorded by Trace and the original files stored and access-controlled on Walrus. Sui represents every asset as a programmable object, allowing datasets and their licenses to be managed onchain, and the network executes independent transactions in parallel that settle in under a second. Walrus extends that capability to large files by storing massive AI datasets efficiently and ensuring data is only readable by licensed buyers. The combination delivers storage, access control, ownership tracking, and verifiable compute inside a single ecosystem, according to the announcement.
