Why

You want to be able to prove someone claimed something at a specific time. For legal reasons, for archival reasons, or to back up claims made by an LLM.

How

Web service. You give it a link to the resource, it downloads and archives the inner http payload, then the certificate chain and info. Then adds the archive to IPFS and returns the CID. It then publishes the existence of the hash and the signs it with the key of the downloader so we know the MAC hasn’t been altered.

if the http payload already exists, winner! we now have two proofs.
