Alkimi Integrates Sui Stack for On-Chain Advertising

Alkimi adopts the full Sui tech stack to bring digital ad delivery, data, and payments fully on-chain with speed, transparency, and scale.

Decentralized advertising platform Alkimi has officially integrated the full Sui technology stack—comprising the Sui Blockchain, Walrus, Nautilus, and Seal—to bring the digital advertising supply chain entirely on-chain. The integration marks a significant milestone in blockchain commercialization, as it reimagines one of the largest legacy industries with transparent, verifiable, and automated infrastructure.

This end-to-end transformation means that core advertising processes—including delivery, verification, payment, and data management—can now be executed entirely on-chain, eliminating opacity and inefficiencies that have long characterized the digital ad ecosystem.

Reengineering Advertising Infrastructure with Sui Technology

Alkimi’s adoption of the Sui stack reflects a deliberate move away from legacy ad tech, not just replicating traditional systems on-chain, but rebuilding the architecture around principles of trust, auditability, and decentralization. Each component of the Sui stack plays a distinct role in enabling this transformation:

• Sui Blockchain serves as the foundational layer for coordination. It enables fast, verifiable settlement of transactions between advertisers and publishers, supporting outcome-based payments with sub-second finality.
• Walrus, Sui’s decentralized blob storage solution, enables Alkimi to put massive volumes of ad-related data on-chain. Currently, the platform processes over 25 million ad impressions per day, and Walrus supports this scale with cost-effective storage and high data availability, ensuring advertisers can transparently access performance metrics in real-time.
• Nautilus provides secure, verifiable execution environments. Through trusted execution environments (TEEs), Alkimi independently validates ad delivery and automates financial reconciliation based on actual performance, reducing fraud and ensuring contractual obligations are met.
• Seal handles the encryption and access control of sensitive advertising metadata. By decentralizing access to proprietary data, Seal helps maintain confidentiality for high-profile clients—including Fortune 500 brands—without compromising the trustless nature of the network.

Demonstrating Viable Blockchain Commercialization

Alkimi’s platform already supports advertising campaigns from major global brands such as AWS, TikTok, Currys, and Polestar. These early adopters demonstrate how the Sui-based infrastructure is capable of supporting both global scale and enterprise requirements. Beyond transparent media buying, the infrastructure unlocks future possibilities for monetizing data, including licensing models and decentralized finance applications specific to advertising (AdFi).

“This isn't about replicating legacy ad systems on-chain,” said Alkimi CEO and Co-Founder Ben Putley. “It’s about delivering a fundamentally better system—more transparent, efficient, and equitable for all participants.”

By removing opaque intermediaries, Alkimi’s platform ensures that value flows directly between advertisers and publishers. Fees are reduced, payments are accelerated, and performance becomes provably trackable on-chain.

A Blueprint for Web3 Advertising

The collaboration between Alkimi and Sui illustrates how blockchain infrastructure can go beyond DeFi or NFTs to power complex, real-world use cases at scale. For developers and brands, this partnership serves as a proof of concept for building decentralized applications that address longstanding inefficiencies in multi-billion-dollar industries.

The adoption of the complete Sui stack allows Alkimi to deliver a modernized media supply chain—one where every impression, click, and payment is verifiable, auditable, and secure by design.

As Alkimi continues to expand its platform and client base, this integration sets a precedent for how Web3 technology can be applied to high-volume, enterprise-grade systems, bridging the gap between technical innovation and commercial utility.
