TLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free. Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files.

I've just launched a new site that creates Trusted Timestamps. Anyone can use it to make any data immutable going forward in time. By "verifying" a Trusted Timestamp against a file, you certify that file has not been altered since the time the Trusted Timestamp was created at. Trusted Timestamps are not a new idea, there is a standard defined in RFC3161 and some other prior work as well. My design though is different as it is based on plain-text, human readable files.
