Congratulations to the 2025 IC3 Blockchain Camp hackathon winners! After a week of building, here are the standout projects that took home the top prizes 🧵

1st Place - Risk Aware Restaking Restaking networks let validators reuse their staked assets to secure multiple blockchain services simultaneously. @roibarzur and his team analyzed scenarios where services implement risk-aware caps to limit excessive restaking participation. This doesn't exist today, but Roi and his team say it could improve network security. Under such constraints, they proved that splitting their stake is mathematically optimal and developed algorithms to compute the best allocations across services.

2nd Place - DAO Buddy This project, built on IC3’s VBE dashboard, is a natural language interface designed to offer actionable insights into Arbitrum DAO proposals. Its goal is to educate voters and combat voter fatigue. The prototype pulls data from Tally, Tableau, Snapshot, LobbyFi, and the DAO forum to help users with tasks such as: - Drafting proposals in the DAO's required format - Casting votes on active proposals - Summarizing forum chatter and understanding how each proposal might affect the DAO’s direction - Analyzing DAO delegate positions on various issues

3rd Place - DeadDrop @0xfanzhang and the team behind DeadDrop built a system for bug hunters to responsibly disclose smart contract bugs to deployers with confidentiality and spam prevention. While existing BlockChat systems can be used to reach smart contract deployers, they also learn the message recipients, revealing which smart contracts are buggy. DeadDrop uses Oblivious Message Retrieval (OMR) and TEEs to ensure private communication between the bug hunters and smart contract developers.

Honorable Mention - T-E-Esports The T-E-Esports team led by @socrates1024 identified how TEEs can reduce the reliance on trusted server operators in online games and enable blockchain interfaces with them. They ran a Luanti server (an open-source, Minecraft-like game engine) inside a TEE container which reads game settings from a smart contract, begins a 1v1 battle game, and finally reports the outcome of the battle to the smart contract.

That's a wrap on this year's hackathon. We'll share an interview with the first place team next week, so stay tuned 👀
