How Alkimi and Sui Are Fixing the Broken Ad Ecosystem

A first-of-its-kind partnership will bring billions in ad spend on-chain Sui, the only blockchain built for mass adoption, is excited to share that leading decentralized ad platform, Alkimi, has adopted the full stack of Mysten-created technologies – including the Sui blockchain, Walrus, Nautilus, and Seal; to bring digital advertising on-chain including the entirety of its commercial supply chain, advancing one of the largest and most commercially viable sectors and showcasing how these innovations work together to modernize a legacy industry. Mainstream adoption has already begun, with brands like AWS, TikTok, Currys, and Polestar engaging through Alkimi’s ad platform supercharged by Sui, demonstrating the breadth of interest from both international and regional players in leveraging decentralized advertising solutions. “Alkimi is fixing a broken digital and advertising ecosystem by bringing it on-chain, and we are proud to be the network chosen for such an important job,” said Christian Thompson, Managing Director at Sui Foundation. “Sui and its stack ensure the experience for Alkimi and their partners is fast, secure, transparent, and able to function completely on-chain – the only way the benefits of decentralization can be fully realized.” A complete blueprint for blockchain commercialization Each Mysten-created product plays a critical role in bringing this modernized advertising experience to life:

The Sui blockchain is the coordination layer for Alkimi’s offering, powering verifiable, outcome-based transactions between advertisers and publishers.

Walrus supercharges Alkimi’s capabilities, enabling the platform to scale efficiently by putting data onchain. Currently delivering over 25 million ad impressions per day, Alkimi is expanding its network of publishers and global brands. Walrus ensures the data infrastructure keeps pace, providing a reliable, cost-effective, and high-performance solution. With real-world advertisers requiring transparency and auditability, Walrus gives Alkimi the foundation to deliver trusted, accurate data at scale.

Nautilus allows Alkimi to independently validate ad impressions and run financial reconciliation logic in verifiable trusted execution environments (TEEs) — ensuring advertisers and publishers are paid based on provably accurate delivery data and help ensure agreements between advertisers and publishers are met.

Seal encrypts and manages access to the sensitive ad impression data and related metadata of Alkimi’s Fortune 500 clients without relying on centralized services, making a fully on-chain advertising platform possible—protecting brand and publisher confidentiality while keeping the system fully decentralized.

“We had the tech, and we knew it needed to scale, that’s when the team at Sui really leaned in,” said Ben Putley, CEO and Co-Founder of Alkimi. “They understood our vision to rebuild digital advertising into something more transparent and equitable. Bringing it onchain isn’t about replicating the legacy systems, it’s about giving advertisers, publishers and users a fundamentally better experience, powered by faster, more secure, and decentralised infrastructure.”

Alkimi’s platform removes opaque intermediaries from the advertising supply chain, redirecting value directly between advertisers and publishers. By exposing where spend was previously lost, bringing transparency, reduced fees, and accelerated payments. Powered by Sui’s high-performance blockchain, this infrastructure will also unlock future opportunities for data monetisation, from licensing models to AdFi innovations.

By adopting the full Sui Stack, Alkimi is building a next-generation advertising infrastructure that brings trust, auditability, and automation to the media supply chain.
