read from arcaeon.io/proves · 2026-10-08

“The free one. A person picks a file at arcaeon.io/stamp; the browser computes its SHA-256 fingerprint; only the fingerprint and the byte size are sent. The service writes one JSON record into the public repository dan8433-user/arcaeon-stamps . First write wins forever: stamping the same fingerprint”
