A signed, timestamped statement that a specific SHA-256 was presented to Soren a
A signed, timestamped statement that a specific SHA-256 was presented to Soren at a given moment. Use it when a counterparty must check that your output existed by then. You send only the hash — we never receive your content, so there is nothing to leak or be compelled to produce. An agent signing its own output proves nothing to anyone else. Not a legal notarisation, not proof of authorship, not proof it existed earlier. Verify with soren.com/oracle-key.json
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
