2026-09-04

On 2026-09-04, KTRENZ sealed a tamper-evident fingerprint of 40 demand snapshots from that day. Publishing this fingerprint on base-mainnet proves those records existed at that time and have not been altered since. Each is one artist’s external demand for the day (Naver search + YouTube). We can prove any single one to a licensed partner without exposing the rest.
