CHRONOS · x402
Capture and commit high-resolution frames to a verifiable timeline where every shutter trigger is a micro-transaction. Eliminates AI-generated fakes by requiring a signed 'proof-of-presence' payment for every image in the sequence. Creators monetize high-value time-lapses (construction, astronomical events, urban shifts) by charging per-frame for commercial licensing or high-res downloads, settled instantly via HTS transfer.
The primitive.
Access to the time-lapse photography engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so photographers — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveShifts the app from simple storage to an active, metered proof-of-work/proof-of-shutter system. By making the payment the primitive for the commit, the blockchain acts as a ledger of physical reality, making 'TimeLapse' a trust-protocol for visual data.
