Arkiv Ideathon · August 2026
Each entry has its own page: the design running in one unedited real-time take, plus a narrated walkthrough. All subtitled. Nothing is deployed and nothing is staged.
Challenge 3 · DeFi
The 31 node observations behind a single Chainlink ETH/USD print, decoded from mainnet and written as 31 attributable readings 868 bps apart. → watch

How the demos were made: narrate.py (neural voiceover +
subtitles) and record.mjs (the capture) — one pipeline, one spec name each,
committed and rerunnable with npm run video:demo and npm run video:selisih.
The two walkthroughs predate that pipeline; see the README.
