RootLens | Frontier Hackathon

Couldn't see much of the cherry blossoms because of the rain, but had an awesome time with Superteam!🌸 BTW, this photo is verified as non-AI-generated. Scan the QR code and check it out!👀 @SuperteamJapan @sol_hack3rs

Insightful review session for RootLens with robot hardware expert Assoc. Prof. @AyatoKanada . Deep dived into hardware innovation and mapped out the next key experts for our hearing process.

Introducing Rootlens, the anti-deepfake camera This is the foundational technology for combatting deepfakes across all sectors This won the Grand Prize at the @sol_hack3rs Global Hackathon, and our current entry is for the @colosseum Frontier Hackathon Product demo coming soon @C2PA_org

📷 RootLens — Week 2 update We're building the anti-deepfake camera. Snap your day. Train AI. Get your pay. Just by shooting with your phone, your video becomes AI training data you can sell. The person who captured it gets paid. The problem Robotics companies are spending over $100M/year on real-world video data. They're strapping iPhones to gig workers' foreheads in Nigeria and India, paying $15/hour to film them doing chores. (MIT Tech Review, April 2026) But once you pay people per video, some will cheat by submitting AI-generated fakes to get paid. This is a problem across AI training data, already seen in text and images. If robots train on fake data, they fail in real homes. Our approach RootLens signs your video at the moment of capture, inside a secure chip. The signature binds sensor data like IMU and depth into the video through the C2PA standard, so the whole package is tamper-evident. Other sensor data can be added when it helps. We don't detect fakes. We prove what's real. This week we pivoted here. What we did ・Redefined our value proposition ・Deep-dived the Physical AI data market (competitors, regulation, tech stack) ・Rewrote our core assumptions ・Drafted the concept spec (system architecture, bounty mode, x402 settlement, KYC, EU AI Act) ・Built the pitch deck and pitch script ・Had a conversation with Shogo Omori (CAEN Inc.) Next week ・Start looking for pilot partners ・Iterate on the pitch through review rounds ・Publish technical breakdown videos on X Building in public. Feedback welcome.

teams participating in @colosseum Frontier are building pretty unique apps. some of them: > @anon0mesh - offline p2p crypto payments via mesh networks > @rootlens_sol - anti deepfake camera > @fairscalexyz - reputation infra. their endpoints include checking repayment history & debt - essential for building new age credit products on top > @JurassicFi - tokenizing (?) fossil fuels because why not. these guys didn't give up on their childhood passions

Building with Sol Hack3rs @colosseum

「AI生成ではない」ことを証明する新技術を開発したRootLensチームの皆さんとお話ししました。 2024年、タイムラプス動画の添付を必須にすることで「手作り」を証明する、AIを使わない作品だけのプラットフォーム「notAI」を開発していましたが、AI技術の進化速度が想定を超え、真正性の担保が難しくなったため、開発を中止しました。 RootLensの技術は、当時の私が越えられなかった真正性担保の壁を、まさに突破しうるものだと感じています。 notAI開発中止から2年が経った現在、AIはより身近な存在になり、日常生活の中でもAI生成コンテンツを見かけるようになりました。 だからこそ改めて、「棲み分け」として、AI生成コンテンツと人間によるコンテンツを区別できるプラットフォームが必要となってきているのではないかと私は考えています。

Just pitched RootLens to @shogo_oomori, Founder & CEO of CAEN Inc. We might see a new product powered by RootLens technology coming from CAEN.

We started RootLens as an authentic-only SNS. After interviewing fact-checkers, journalists, and Superteam members, we learned: people who already have trust don't need us. The ones who do are people with no voice and no way to prove what's real. Back to building.

Reviewed RootLens with frontline journalist.　@Yusuke_Murayama Realized our initial assumption was wrong. The real target? People caught in conflict zones. Deepfakes have killed the trust in their SOS posts. RootLens restores that trust, helping journalists and rescue teams act.

Discussed RootLens with photojournalist @Masa_Michishiro Great insights! Next up: Hearing with the Photo Association.

Thanks to Shigeru Sato from @SuperteamJapan for the support. We're building the social network where every post is proven real. rootlens.io

"It's an important theme. Showing that you intentionally captured something matters. I'm curious how you connect the footage to the person who filmed it." Founder of a blockchain company

I went to TEAMZ Summit in Tokyo, pitched RootLens to 10 strangers, and asked what they thought. 8 gave me feedback. Here's what I heard ⬇️
