Sui has confirmed the full integration of decentralized advertising platform Alkimi into its blockchain ecosystem, a move that is set to redefine the digital advertising supply chain by making it entirely onchain. The partnership is designed to overhaul how advertisers and publishers interact by leveraging blockchain technology to enable transparent, efficient, and real-time ad operations.
This integration facilitates all critical advertising functions—such as ad delivery, verification, payment settlements, and data handling—onchain. The goal is to eliminate inefficiencies and longstanding issues in the traditional digital advertising model, including hidden costs and unverifiable metrics. By moving these processes to a decentralized infrastructure, the collaboration is expected to bring greater accountability and operational speed to an industry that has often faced criticism for its opaque structures.
Sui plays a central role by powering the transaction layer within the advertising ecosystem. It facilitates instant settlements between advertisers and publishers, enabling direct and traceable financial interactions. As transactions are completed in real time, advertisers and content platforms benefit from faster revenue recognition and reduced payment delays.
Supporting this new model is Alkimi’s proprietary technology stack, composed of several specialized components. Walrus, for instance, is used to store large volumes of advertising data onchain, reportedly handling more than 25 million ad impressions each day. This enables advertisers to track performance transparently and evaluate the impact of their campaigns with confidence.
Nautilus, another key module, verifies the actual delivery of ads using secure and trusted execution environments. This ensures that campaign data and delivery confirmations are accurate and tamper-proof. Additionally, Nautilus enables automated financial reconciliation, which aligns payments with real-world results rather than estimated or assumed outcomes.

Seal, the final piece of the infrastructure, takes care of encrypting and managing access to sensitive metadata related to advertising campaigns. While this ensures that critical business information remains confidential, it also retains the decentralized nature of the system, allowing multiple stakeholders to interact securely without compromising data integrity.
Several major brands have already begun leveraging Alkimi’s platform for advertising campaigns. Names such as AWS, TikTok, Currys, and Polestar are reported to be among the early adopters, signaling confidence in the system’s potential to address long-standing industry challenges.
Alkimi’s leadership has positioned this integration as more than just a shift from traditional to digital infrastructure. Instead, it is seen as an opportunity to fundamentally rebuild the advertising model to be more transparent, equitable, and efficient for all participants involved in the ad ecosystem.
With this development, Sui and Alkimi are collectively demonstrating how decentralized technologies can be used beyond finance and gaming, extending into global industries like digital advertising. The partnership marks a key milestone in the growing movement toward Web3-native infrastructure, where automation, transparency, and data integrity are built into the foundation of digital operations.
