((("bitcoin", "use cases", id="GSuses01")))Bitcoin is an innovation in the ancient technology of money. At its core, money simply facilitates the exchange of value between people. Therefore, in order to fully understand bitcoin and its uses, we'll examine it from the perspective of people using it. Each of the people and their stories, as listed here, illustrates one or more specific use cases. We'll be seeing them throughout the book:
North American low-value retail::

This story will introduce us to the software, the exchanges, and basic transactions from the perspective of a retail consumer.

((("transactions", "advanced", "Pay-to-Script-Hash")))((("scripting", "Pay-to-Script-Hash", id="Spay07")))Pay-to-Script-Hash (P2SH) was introduced in 2012 as a powerful new type of transaction that greatly simplifies the use of complex transaction scripts. To explain the need for P2SH, let's look at a practical example.
((("import/export use case")))((("use cases", "import/export", id="mohamseven")))((("scripting", "Pay-to-Script-Hash", "import/export example")))((("Pay-to-Script-Hash (P2SH)", "import/export example")))In <<ch01_intro_what_is_bitcoin>> we introduced Mohammed, an electronics importer based in Dubai. Mohammed's company uses bitcoin's multisignature feature extensively for its corporate accounts. Multisignature scripts are one of the most common uses of bitcoin's advanced scripting capabilities and are a very powerful feature. ((("accounts receivable (AR)")))Mohammed's company uses a multisignature script for all customer payments, known in accounting terms as "accounts receivable," or AR. With the multisignature scheme, any payments made by customers are locked in such a way that they require at least two signatures to release, from Mohammed and one of his partners or from his attorney who has a backup key. A multisignature scheme like that offers corporate governance controls and protects against theft, embezzlement, or loss.

((("use cases", "import/export", id="mohamseventwo")))Our example uses the story of Mohammed, the company owner in Dubai who is operating an import/export business.
((("transactions", "advanced", "multisignature scripts")))((("scripting", "multisignature scripts", "import/export example")))((("multisignature scripts")))In this example, Mohammed wishes to construct a company capital account with flexible rules. The scheme he creates requires different levels of authorization depending on timelocks. The participants in the multisig scheme are Mohammed, his two partners Saeed and Zaira, and their company lawyer Abdul. The three partners make decisions based on a majority rule, so two of the three must agree. However, in the case of a problem with their keys, they want their lawyer to be able to recover the funds with one of the three partner signatures. Finally, if all partners are unavailable or incapacitated for a while, they want the lawyer to be able to manage the account directly.
