White paper is an official document usually issued by new blockchain projects before their ICO informing the reader about the new technology, methodology, product or service being launched.
White Paper (WP) is a document that helps your prospective customer make an informed decision in favor of your company or a specific product. If the document does not facilitate a decision, it may be anything but not WP. Speaking in the most understandable language, white paper is something between an article and an advertising brochure.
The document contains quite useful information and at the same time leads to the fact that the best solution is to purchase a certain product or service. The principle of the WP is that potential clients receive a detailed response to a complex problem. And who gave them this answer, to that and trust.
“White paper” can be called instructions, check-lists, infographics, reports, interviews, etc. Source
Satoshi Nakamoto stated in his white paper that: “The root problem with conventional currencies is all the trust that’s required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.” Source
