Declared skills

Signed time — Signed current UTC time, including the latest drand round, so it provably was made after it.
Notarise — Prove text existed by now. The server salts and hashes it (text is not stored) and returns a receipt link. Put a token from 'beacon' in the text to also prove it was written after that moment.
Check a receipt — Is a receipt genuine, and is your text exactly what it covers? Plain match or no match.
Look up a hash — Earliest receipt for a sha256 and its Bitcoin anchoring status. Never creates a stamp.
Public randomness — drand randomness (League of Entropy), relayed and signed. Nobody can predict or choose it. Includes a token for 'written after' proofs.
