Chapter Seven: Expanding Bitcoin Transactions with Multisigs

Basic bitcoin transactions: (1) send funds; (2) to a single recipient; (3) from a single machine; (4) immediately. However, all four parts of this definition can be expanded using more complex Bitcoin transactions. This first chapter of "Expanding Bitcoin Transactions" shows how to vary points (2) and (3) by sending money to an address that represents multiple recipients (or at least, multiple signers).
