Alkimi brings billions in ad spend on-chain to fix broken ad ecosystem
Decentralised ad platform Alkimi has partnered with Sui, a blockchain built for mass adoption, to bring billions of dollars in digital advertising revenue on-chain.
Intending to fix a broken ad ecosystem, Alkimi's platform removes opaque intermediaries from the advertising supply chain, redirecting value directly between advertisers and publishers.
The ad platform – which is already seeing mainstream adoption of ad spend on blockchain through brands such as Amazon's AWS, TikTok, Polestar and Currys – exposes where spend was previously lost, bringing transparency, reduced fees and accelerated payments to the digital advertising landscape.
The partnership sees Alkimi adopt the full stack of Mysten-created technologies – including the Sui blockchain, Walrus, Nautilus, and Seal – to bring digital advertising on-chain, advancing one of the largest and most commercially viable sectors and showcasing how these innovations work together to modernise a legacy industry.
Powered by Sui's high-performance blockchain, Alkimi infrastructure will also be able to unlock future opportunities for data monetisation, from licensing models to AdFi innovations.
'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 realised,' Thompson added.
Each Mysten-created product plays a critical role in bringing this modernised advertising experience to life:

Seal encrypts and manages access to the sensitive ad impression data and related metadata of Alkimi's Fortune 500 clients without relying on centralised 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,' Putley concluded.
