You can reply concisely and technically. Suggested answer: No. Verification does not depend on the TimeProofs service being online. A TimeProofs proof is a self-contained, cryptographically signed file. Anyone can verify it offline or with

Hi HN, I’m the creator of TimeProofs, an open, stateless proof-of-existence protocol and API. The problem it tries to solve is simple: How can you prove that a digital event or file existed at a given time, without uploading or exposing the

Fair question. It’s useful when you need to prove priority or existence without revealing the content. Examples: – You wrote something (code, research, idea) and want proof it existed before publication or disclosure. – You generated AI out

For example: you generate a file (code, dataset, document, AI output) and later need to prove it already existed at a certain time. TimeProofs lets you create a small proof file you can keep. Anyone can later verify the timestamp without se

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). Verificati

That’s exactly the right framing — those questions matter. In many cases, a secure hash alone is enough to prove integrity (“this file hasn’t changed”). The gap usually appears around time and independence. A hash answers what, but not alwa
