2026-07-22
On 2026-07-22, KTRENZ sealed a tamper-evident fingerprint of 25 K-pop observations from that day. Publishing this fingerprint on base-mainnet proves those records existed at that time and have not been altered since. Each observation is one artist moment — who, where, when, and the source. We can prove any single one to a licensed partner without exposing the rest.
Moments in this seal
Already-public moments, each cited to its source. Real-time, precise, and private locations (homes, hotels, airports) are withheld — an anti-stalking record, not a live feed.

How to verify a single record: a licensee is handed one record + its salt + a Merkle proof, re-hashes it, and confirms it resolves to the Merkle root above — proving inclusion without exposing anyone else's data. Get in touch for a licensed feed.
