How Alkimi Baked Trust into Advertising
Discover how they're using Walrus to make every click verifiable.
Every day, advertisers spend millions on ads that may never be seen by real people. Brands can't verify what they're paying for, consumers are tracked across every click, and the entire system runs on complex infrastructure riddled with middlemen and extra fees.
Walrus gave Alkimi, a blockchain-based ad exchange, the data foundation needed to solve this: a tamper-proof, auditable system where every impression is provably real, every click is verifiable, and “just trust us” is replaced with cryptographic proof.
Can your data layer keep up?
Alkimi started out with a simple challenge: get a data layer that could keep up with the fast-paced world of advertising, where billions of clicks, impressions, and transactions flow through the system daily. They relied on validators for consensus and recording key transaction metadata, but storing and reproducing the full volume of execution data onchain was too slow and expensive. Their previous solution involved centralized storage, leaving their customers dependent on a single provider's uptime and payment processing for data accessibility, which also undermined their goal of a fully decentralized system.
Proving every click
Walrus and the Sui Stack gave Alkimi exactly what they needed: the infrastructure necessary to handle massive volumes of data without compromising on speed, cost, or auditability. Instead of relying on a single provider, Walrus's replicated storage spreads data across a distributed network—lowering costs per gigabyte while making everything more durable and available. Now Alkimi can keep every impression, every click, every transaction auditable and verifiable.
“The Walrus integration was seamless. Clear, well-organised documentation meant our team spent less time troubleshooting and more time building.”
