Prove you called it.

Write the decision or prediction before the outcome, state your confidence, and get a hash-locked receipt with a public verify link. Anonymous. Free. When you turn out to be right, the receipt is your proof — timestamped and tamper-evident.

How the integrity works (exactly): at creation we compute SHA-256 over your statement + confidence + dates, store it, and print it on the receipt. The verify page recomputes the hash live from the stored fields on every visit — any edit shows up as a mismatch. v0 is tamper-evident within AEQUARA’s append-only storage; independently anchored roots (published Merkle checkpoints, like our attestations use) are the v1 upgrade. No name, no email, no tracking identifiers are stored with a receipt.
