Meet the Haulout Hackathon Winners

Meet the winning projects from the first hackathon combining Walrus, Seal, and Nautilus to build the future of decentralized, verifiable data."

The future of data requires trust, transparency, and verifiability. But making that vision a reality requires new ways of thinking, a different set of tools, and developers willing to think outside the box.   

Launched in 2025, the Haulout Hackathon was the first hackathon to bring together three tools that are transforming how data works together: Walrus for decentralized data, Seal for access control, and Nautilus for verifiable off-chain computation. Participants were challenged to use these tools to create practical solutions in four different areas: data economy and marketplaces, AI-powered workflows, provably authentic systems, and data security.

From hundreds of submissions with participants in 27 different countries, here are the projects that stood out for their innovation, technical execution, and potential to shape the future of data.

Introducing the Winners

Our panel of judges selected three winners in each category, plus three projects that were noteworthy for their technical implementation. 

AI and Data

Spectra
1st place
Spectra is a content moderation system that filters harmful posts and images without exposing user data. It runs AI models in a secure environment that keeps everything private and transparent, so no centralized company controls or sees the content.

INFINITE HEROES
2nd place
Infinite Heroes turns selfies into a personalized comic book using AI. By combining AI agent-driven storytelling with high-capacity Walrus storage, the platform creates unique hero characters and comic stories that players can own as NFTs.

TradeArena
3rd place
TradeArena is an AI trading competition where multiple AI models compete by making real crypto trades, with every decision and on-chain action recorded on Walrus.

Data Economy and Marketplaces

Storewave
1st place
Storewave is a marketplace for unused Walrus storage space. It automatically finds the cheapest storage options and can reduce costs by 20-40% by letting users buy and sell storage allocations.

Krill Tube
2nd place
KrillTube is a video platform where creators earn micropayments as viewers watch their content. Viewers pay only for what they actually watch, with payments flowing directly to creators in real-time.

Fundsui
3rd place
Fundsui is a decentralized, censorship-resistant platform similar to Patreon where creators can offer paid subscriptions to encrypted content like podcasts.

Data Security and Privacy

Wit With Withub
1st place
Wit With Withub is a decentralized, encrypted alternative to GitHub where developers can store and collaborate on code privately, protected from AI training scrapes and other risks.

SuiVerify
2nd place
SuiVerify is a decentralized identity infrastructure that verifies your identity documents privately. It creates reusable identity proofs you can share across platforms while keeping your personal data secure.

Chronos
3rd place
Chronos is a decentralized "dead man's switch" that releases your encrypted data to chosen recipients if you stop checking in. It solves the problem of passing on digital assets and sensitive information securely when something happens to you.

Provably Authentic

perma.ws
1st place
perma.ws creates permanent, cryptographically verified archives of webpages. Each snapshot includes proof of when it was captured and that it hasn't been altered.

Aver.Email
2nd place
Aver.Email lets you prove an email is authentic without revealing its full contents. You can verify specific parts of emails while keeping sensitive information private.

Delphi
3rd place
Delphi is a prediction market where users bet on yes/no outcomes like crypto prices. It uses secure oracles to automatically resolve markets fairly.

Best Technical Implementation

Project S.O.N.A.R.
Project S.O.N.A.R is a privacy-focused marketplace where creators sell audio files like music or recordings. Every file is verified for quality, and buyers get secure access after purchase.

Tusk
Tusk is a hiring platform that matches candidates to jobs using AI while keeping all personal data encrypted. Your information stays private until you choose to share it with employers.

zkDungeon
zkDungeon is a roguelike RPG built for speed. Every action is cryptographically verified on-chain to prevent cheating, but the game runs locally so there's no lag or waiting for transactions to confirm.

Join the Data Revolution: Build on Walrus

What do all these projects have in common? They're reimagining what's possible when data is truly decentralized. From AI-powered content platforms and encrypted collaboration tools to verifiable archives and privacy-preserving marketplaces, you can achieve a lot with Walrus, Seal, and Nautilus under the hood.
