About

Walrus is a next-generation decentralized storage network for unstructured data and rich media content such as large text files, videos, images, and audio. Leveraging innovations in erasure coding, Walrus offers exceptional data availability and robustness with minimal replication overhead for cost efficiency. Powered by Sui as the coordination layer, Walrus scales to hundreds or thousands of networked decentralized storage nodes without compromising performance.

Prizes

📱 Best app using Walrus for storage$4,000
Up to 2 teams will receive $2,000
Use Walrus for decentralized storage in a new Web3 app. Try to focus on an app idea where decentralized storage solves a current pain point. For example, hosting for NFTs, democratization of AI models, or crowdsourced video streaming.

Qualification Requirements

- The app must upload data to Walrus testnet or mainnet. - The app must be newly developed.

🔧 Best developer tool for Walrus$6,000
Up to 3 teams will receive $2,000
Create a new tool for developers integrating with Walrus. Walrus is a chain-agnostic decentralized storage network, and therefore presents a lot of opportunities for useful developer tooling. For example, SDKs, caching layers, streaming tools or blob management tools. Check out the Awesome Walrus repo for existing developer tools, to check that your idea doesn't currently exist. Check in with the Walrus team at the hackathon to verify your idea before you get in too deep!

Qualification Requirements

- The tool must be integrated with, or enable the developer to work with, Walrus testnet or mainnet. - The tool must be newly developed.
