Oracle Receipt Registry

Every prediction. Anchored before the outcome.

The PROOF oracle commits prediction receipts to Solana before any outcome is known. SHA-256 hash of prediction_text + timestamp + oracle_pubkey, signed and anchored. Any receipt below can be independently verified — no trusted third party required.

Fetching receipts from oracle…

Any receipt can be independently verified.

Step 1 — Fetch
Get any receipt by ID from the public registry at /api/v1/receipts
Step 2 — Recompute hash
Compute SHA-256(prediction_text + anchor_timestamp + oracle_pubkey)
Step 3 — Check the ledger
Confirm anchor_tx exists on Solana at anchor_block_height and contains the hash
Step 4 — Verify signature
Confirm oracle_signature verifies over canonical receipt JSON using the oracle's Ed25519 pubkey
