Daily integrity seal · B.Now sightings

2026-07-20

On 2026-07-20, KTRENZ sealed a tamper-evident fingerprint of 40 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.
