1. Hash the record: sha256sum headline-ce2dad5bce03.json prints ce2dad5bce03b2d3c1ee983241c322b538cdab338761199da4327863cdd84d0f. Its first twelve characters are the end of this record's address.
2. Drop headline-ce2dad5bce03.json and headline-ce2dad5bce03.json.ots onto opentimestamps.org, which checks the receipt against the Bitcoin block chain. Or, with the OpenTimestamps client and a Bitcoin node: ots verify headline-ce2dad5bce03.json.ots (ots upgrade first while the receipt is pending).
3. Open the Wayback Machine's captures above: the capture of the record page shows this hash as it stood then, and the capture of the story page shows the newsroom's own page.
