Walrus

Walrus is a decentralized storage network that stores and delivers raw data and media files — like videos, images, and PDFs — without sacrificing performance or accessibility. With Walrus, your data is always secure and available. This program covers the full Walrus protocol: smart contracts, storage nodes, aggregators, and core libraries. All related code is available in the [MystenLabs/walrus](https://github.com/MystenLabs/walrus) repository on GitHub. *Theoretical entries, entries without a working PoC, and entries generated by an LLM tool based on generic prompts will be discarded. Any medium or higher severity vulnerability must include a working PoC that can be demonstrated on a local test environment reproducible with the instructions in the appendix. The PoC must show that the vulnerability can be triggered by an external input to a Walrus component (storage node, aggregator, contracts).*
