Post-quantum evidence infrastructure

Records that outlive the algorithms that signed them.

سِجِلٌّ يبقى، وتوقيعٌ يتجدَّد

Wathīqa seals sovereign records with post-quantum cryptography — and keeps every seal renewable, so an archive signed today remains verifiable across each algorithm transition to come.

The quiet problem

A signature is a promise with an expiry date.توقيعٌ له أجل

Every digital signature securing today's official records rests on mathematics that quantum computers are expected to break. The documents themselves must last far longer than the cryptography protecting them.

i

The archive outlives the algorithm

Title deeds, judgments, decrees, and civil records must stay provable for fifty years or more. No signature scheme in history has stayed trusted that long.

ii

Harvest now, forge later

Records copied today can be attacked at leisure once quantum machines arrive. Anything whose authenticity matters in 2040 needs quantum-resistant evidence now.

iii

Migration is not a one-time fix

Even post-quantum algorithms will one day be replaced. An archive needs a way to renew its evidence under each successor — without ever touching the original document.

The approach

Seal. Witness. Renew.خَتْمٌ وشُهودٌ وتجديد

Three operations, grounded in published standards, verifiable by anyone — offline, on their own machine.

Sealخَتْم

Every record receives a content address — a SHA-3 Merkle fingerprint that changes if even one byte of the document changes.

Witnessشُهود

Post-quantum signatures bind the seal to a moment in time, bracketed by a public randomness beacon and a transparency log — evidence no single party can backdate.

Renewتجديد

When cryptography moves on, the evidence is re-witnessed under the successor algorithm. The chain grows; the document never moves.

Our contributions

The Internet-Draft is authored and pre-submission; the enterprise arc is a live IANA registration carried in every evidence record we emit.

The proof is a tool you can hold.

The sovereign verifier is a single self-contained page that confirms a real evidence record against its document — in English or Arabic, entirely offline on your own machine, with no byte leaving the device. We share it directly with reviewers, partners, and federal counterparts, on request.
