CLUSTER AUTHENTICITY-VERIFIES-WEB · 31 ENTRIES · EARLIEST ENTRY 2025-09-08

Digital certificate verification platforms

This cluster comprises web-based tools for issuing, verifying, and validating digital certificates and documents, using QR codes, cryptographic signatures, and checksum checks. The cluster's dated history is too thin to discern a trend—only four dated entries exist before the index start, so its shape remains unclear. Traction is led by opensignature (4 stars), followed by CertiChain and credentio-validator-web (1 star each).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
