The OpenTimestamps team has timestamped every item in the Internet Archive - about 750,000,000 files in total - and made those timestamps publically available via a searchable database. This means that right now you can get timestamps for every book, movie, song, computer program, legal document, etc. in the thousands of collections in the archive. In the future we hope to be able to work with the Internet Archive to extend this to timestamping website snapshots. We're setting up infrastructure to continue timestamping new items as they're uploaded to the archive.
We have preconfigured the project with a simple development web server. The simplest way to start this server is:
npm start
Now browse to the app at [localhost:8000/index.html][local-app-url].
