Hi HN — I’m the creator. TimeProofs is a small protocol to prove that some data existed at a given time, without uploading the data itself. You hash locally, get a signed timestamp, and store a portable proof file (.tproof.json). Verification can be done later, even offline. No blockchain, no accounts, no tracking. Happy to answer questions or hear criticism.
