Certified copy

Record of existence on the internet

Valid and verifiable Sealed on November 9, 2026, 05:05:32 (Central Mexico time)

Memoria y Resistencia hereby certifies que su sistema Turing leyó, el 9 nov 2026, 05:05:16 (hora del centro de México), la nota de Plana Mayor en el enlace público que se indica abajo; que guardó una copia de su contenido; y que la huella digital SHA-256 de esa copia fue sellada por un tercero independiente (FreeTSA, estándar RFC 3161) el 9 nov 2026, 05:05:32 (hora del centro de México). Cualquier cambio en el contenido, por pequeño que sea, cambiaría la huella, y el sello dejaría de coincidir.

GHOSTARCHIVE · ghostarchive.org

In line for Ghostarchive

Turing keeps it in Ghostarchive, a public and independent archive. It goes one at a time, so as not to saturate it, and what has sayings goes first; the link appears here as soon as it is saved. Meanwhile, the copy is already valid with your fingerprint and time stamps.

IV Value as evidence

It is a technical proof of integrity and date. In Mexico, information recorded in electronic media is recognized as evidence, and its weight depends on the reliability of the method used to create and keep it, on its remaining intact and on its being available for later consultation (Commercial Code, art. 1298-A; Federal Code of Civil Procedure, art. 210-A; National Code of Civil and Family Procedure, art. 348).

Este certificado cumple esas condiciones con estándares abiertos, comprobables sin confiar en nosotros: huella SHA-256, sello de tiempo RFC 3161 de un tercero, OpenTimestamps sobre Bitcoin y una copia independiente en Ghostarchive.

It does not replace a notarial certification of facts or a NOM-151 preservation certificate. If you need it for a lawsuit or a formal procedure, the same fingerprint can be backed by them: write to us with the folio.

V How to verify it yourself

  1. Download the seal (sello.tsr).
  2. Download from freetsa.org its certificates cacert.pem y tsa.crt, and check the timestamp: openssl ts -verify -digest f1ac7a465aa9286999e3cfbe1807bffb52b1e1ac30f82a091e2cb3fa8cc473d4 -in cc5udy3bsr-sello.tsr -CAfile cacert.pem -untrusted tsa.crt. It should say “Verification: OK”.
  3. The .ots file can be checked at opentimestamps.org.

How to use the timestamp (sello.tsr)

It is the stamp signed by FreeTSA, an independent third party, under the RFC 3161 standard. It proves the copy's fingerprint already existed at that date and time, and that nobody changed it afterwards.

  1. Download the stamp and save it in a folder.
  2. Download from freetsa.org its certificates cacert.pem y tsa.crt, and put them in the same folder.
  3. Open the Terminal in that folder (you need OpenSSL; it already comes on Mac and Linux) and type:openssl ts -verify -digest f1ac7a465aa9286999e3cfbe1807bffb52b1e1ac30f82a091e2cb3fa8cc473d4 -in cc5udy3bsr-sello.tsr -CAfile cacert.pem -untrusted tsa.crt
  4. If you answer «Verification: OK», the seal is authentic. To view the stamped date and time:openssl ts -reply -in cc5udy3bsr-sello.tsr -text

How to use the OpenTimestamps proof (sello.ots)

It is the proof that the copy's fingerprint was recorded on the Bitcoin blockchain, a public record nobody can alter or delete.

  1. Download the .ots file.
  2. Go to: opentimestamps.org and drag the .ots file to the box on the page.
  3. The page shows you the registered fingerprint. It must be:f1ac7a465aa9286999e3cfbe1807bffb52b1e1ac30f82a091e2cb3fa8cc473d4
  4. It will tell you in which Bitcoin block and on what date it was recorded. If it says it is still pending, try again in a few hours.
