Winners

Two winning teams, each receiving a **$1,500 USDC** stipend toward a one-month stay at Network School.

Cortex

An AI that remembers and forgets the way people do — fresh thoughts stay short-lived and fade for free on Arkiv, while the memories you actually use in decisions graduate into lasting rules. Memory is wallet-owned and RaBitQ-compressed, with an MCP server and Claude plugin bundled so any agent gets a portable digital twin instead of amnesia every session.

**Theme:** AI · Privacy [GitHub](https://github.com/LingSiewWin/Cortex) · [Demo](https://cortex-arkiv.vercel.app/) · [Video](https://www.loom.com/share/68178caad4034e8282ac412a440e0738)

Ark Hive

Makes agent memory a first-class, portable asset on Arkiv. Mint an ERC-8004 agent, then every session, message, scoped memory and hash-chained snapshot is written to Arkiv — signed by your own wallet, not theirs. Ships `arkiv-agent-sdk` on npm so any app can read another agent's memory and keep writing to it.
