Called It

How Receipts Work

  1. You write a Call.
  2. You press Lock It In.
  3. Our server records the exact Call and time.
  4. We generate a cryptographic fingerprint (SHA-256) of the original.
  5. The original Call can never be edited.
  6. Any later updates are stored separately as notes.
  7. When the outcome happens, evidence can resolve the Call.
  8. Anyone can return to the original receipt.

The technical bit (optional)

Each Call is hashed over a canonical representation of its immutable fields (prediction text, author reference, timestamp, deadline, confidence and a random nonce). The hash lets anyone verify the original content hasn't changed. Note: a database timestamp proves when our platform recorded the Call — it is not, by itself, an independent third-party timestamp. The architecture supports adding external trusted timestamping later.
