GWIMYEONWA
An on-chain media guardian that seals AI-media verification evidence onto GIWA
It analyses two things separately: whether a video was generated by AI, and whether its content is harmful. Keeping them apart is the point — authenticity and content risk are different questions, and folding them into one score answers neither.
The verdict is not stored alone. Per-frame signals, a summary of the model output, the file fingerprint and the time of verification are bundled into one evidence packet, hashed, and written to a registry on GIWA Sepolia (chain ID 91342). Only the hash is published, so the video itself stays private while the issuer, the timestamp and the integrity can be checked independently on the GIWA explorer.
The name comes from gwimyeonwa (鬼面瓦), the demon-face roof tile placed on a roof to ward off evil. The team says it moved that guarding role onto digital media. Designed and built by HOLOSTUDIO.

Based on a public statement by the project itself or a credible third party. GIWA has never published an official roster. Phase 3 is also an ongoing stage, so this means admission to it rather than completion.
What is GASOK Phase 3?
GASOK is Dunamu and Upbit's builder program for GIWA, an incubation running five months or more. Phase 3 (Aug–Sep 2026) is the "market readiness & launch" stage, aiming at testnet user metrics and a private mainnet deployment. There are five tracks: DeFi/RWA, Consumer/Social, GIWA-Native, AI/Web3, and Mass Adoption.
What teams admitted to GASOK Phase 3 receive
- Engineering and productization support from the GIWA team, plus industry advisors
- Seoul office space if needed, and press and media support
- A slot at KBW 2026 Demo Day
- A $20K initial grant for the Demo Day winner, with more tied to later KPIs
