Tobacco giant Philip Morris builds a public chain to track stamp duty on cigarette packs

At the London Blockchain Expo, tobacco giant Philip Morris International executive Manoharan said the company is working to create a "public chain", but this is not exactly the "public chain" that people usually understand. The company will use the technology to track stamps on cigarette packs; these stamps are valuable (about $5.50 per pack), and manual processing is easy to falsify, causing $100 million in annual damage to the industry and government; With blockchain traceability and transparency, you can save $20 million.
