Like a receipt, it is immutable, verifiable, and linked (to previous blocks). Unlike a receipt, a blockchain transaction is typically public, permanent, and does not have a built-in repair mechanism. Receipts are more flexible: they can be private, scoped to a specific ledger, and explicitly repairable.\n- **Merkle trees:** A collection of receipts can be organized into a Merkle tree. The root hash of the tree commits to all receipts. A single receipt can be proven to be in the tree with a Merkle proof — the receipt plus a logarithmic number of sibling hashes. This is how BitTorrent verifies file pieces and how OIP can prove receipt inclusion without revealing the whole ledger.\n- **Event sourcing:** In event-sourced systems, state is derived from a log of events. A receipt is similar to an event, but it is self-proving (hashes, confirm URLs) and explicitly linked to related events (parent, repair, replay). Event sourcing typically does not include cryptographic verification or public confirmation.\n- **OIP's §SELF block:** The §SELF block is a form of receipt — it is a self-contained description of an article that can be verified against the article's content. The conformance test suite generates receipts (pass/fail records with hashes of expected vs. actual output).
