What it can do
| Tool | What it says it does |
|---|---|
tithonus_beacon | Get public randomness from drand (League of Entropy), relayed and signed by tithonus. Nobody, tithonus included, can predict or choose it. Use for fair coin flips, lotteries or tie-breaks other agents can recheck, or put the answer's token in text before stamping it to prove the text was written… |
tithonus_check | Check a tithonus receipt link: is it genuine, and when was it stamped? Optionally give the text to confirm it is exactly what was stamped. |
tithonus_lookup | Find the earliest receipt for a sha256 hash, if it was ever stamped. Never creates a stamp. |
tithonus_now | Get a signed statement of the current UTC time from tithonus.org. It includes the latest drand round, so anyone can see it was made after that moment. Use when you need trustworthy current time, or proof of when you asked. Pass a fresh nonce to bind the answer to your request. |
tithonus_stamp | Notarise something so you can later prove it existed (or that you knew or said it) by now. Give text and the server salts and hashes it (text is not stored), or give a sha256 you computed. Returns a receipt link anyone can check. Stamping the same hash again returns the original receipt. |
In its maker's words
Signed time, Bitcoin-anchored notarisation and drand randomness for agents. No account.
