Witnessory
Measures internet adoption of post-quantum cryptography through independent network probes
A monitoring service that tracks global adoption of post-quantum cryptography across the internet through verified probe readings and provides real-time
Overview

A look at witnessory.org
Witnessory tracks how far the internet has moved to post-quantum cryptography using probes on several networks. Every reading is signed and recomputable, providing verified statistics on adoption rates across the internet's infrastructure.
The service offers free tools including a central view, one-time site checks, and the ability to run your own probe from any network. Paid services allow organizations to monitor their own sites' post-quantum readiness over time with alerts, evidence reports suitable for auditors, and API access to the data.
Witnessory emphasizes transparency and neutrality: all figures are derived from deterministic computations over sealed probe readings, results are reproducible, and no result is ever changed or hidden for money.

FAQ
- What is included in the free tier?
- The dashboard, one free check at a time, and the ability to run a probe from your own network are all free. The API also offers 20 new checks per hour from one address with results reused for 10 minutes.
- How do paid services help organizations monitor their sites?
- Paid watch plans check your hostnames daily or every 6 hours from several networks with alerts, provide a page with history, and deliver signed monthly evidence files anchored in Bitcoin for audit purposes.
- What payment options are available?
- Checkout for people opens soon via email signup. Agents can pay now per request in USDC on Base using HTTP 402. Alternatively, contact hello@witnessory.org to buy keys or reports by reply.
- What makes Witnessory results trustworthy?
- Every figure is read from deterministic computation over sealed readings from probes. Every reading is signed, and the same readings with the same aggregator version always produce the same view hash, making results reproducible and verifiable.
