Alkimi and Sui Bring Digital Ads On-Chain, Promising a Transparent, Decentralized Future
In a bold move to reinvent digital advertising from the ground up, decentralized ad platform Alkimi has joined forces with Sui, a blockchain built for scalability and mass adoption. The mission? Drag one of the internet’s most opaque and intermediated industries into the light—by bringing ad transactions on-chain.
With major brands like Amazon AWS, TikTok, Polestar, and Currys already leveraging Alkimi’s platform, this isn’t just an ambitious experiment—it’s a signal that ad tech’s blockchain moment may have finally arrived.
Why It Matters
Today’s digital advertising ecosystem is riddled with inefficiencies: hidden fees, data opacity, slow payments, and an alphabet soup of middlemen. Alkimi aims to eliminate these legacy burdens by redirecting value directly between advertisers and publishers, increasing transparency and drastically reducing fees.
And now, with the Sui blockchain and its entire Mysten tech stack—including Walrus, Nautilus, and Seal—Alkimi believes it has the infrastructure to make good on that promise, at scale.
“Alkimi is fixing a broken digital and advertising ecosystem by bringing it on-chain,” said Christian Thompson, Managing Director at Sui Foundation. “We’re proud to be the network chosen for such an important job.”
Tech Stack with a Purpose
Each piece of the Sui tech puzzle plays a targeted role:
- Sui blockchain – Serves as the transactional backbone, ensuring verifiable, real-time interactions between advertisers and publishers.
- Walrus – Powers Alkimi’s scaling needs by putting ad impression data on-chain. Already handling over 25 million impressions daily, it provides speed, reliability, and transparency at scale.
- Nautilus – Enables independent validation of ad impressions and accurate financial reconciliation. It uses trusted execution environments (TEEs) to ensure all ad payments are based on verified delivery—minimizing fraud and disputes.
- Seal – Encrypts and controls access to sensitive impression and metadata. This keeps the platform fully decentralized while protecting client confidentiality, even for Fortune 500 brands.
A New Kind of AdTech Play
Unlike previous attempts to bolt blockchain onto ad tech, Alkimi isn’t interested in replicating the status quo—it’s about replacing it entirely. CEO and Co-Founder Ben Putley said the partnership with Sui allowed them to scale their original tech and transform it into something “fundamentally better” for all parties involved.
“Bringing it on-chain isn’t about replicating legacy systems,” Putley emphasized. “It’s about giving advertisers, publishers, and users a fundamentally better experience, powered by faster, more secure, and decentralized infrastructure.”
Bigger Picture: Blockchain Finds Its AdTech Use Case
Alkimi’s adoption of Sui represents a rare moment of genuine blockchain utility in a sector dominated by entrenched platforms like Google and Meta. While those giants are unlikely to surrender their positions soon, the potential for trustless, verifiable advertising—especially in industries demanding compliance and transparency—offers an appealing alternative.
And as regulators sharpen their gaze on ad fraud and data privacy, platforms like Alkimi may not just be a novel choice but a necessary evolution.
