A first-in-first-out (FIFO) algorithm spends the oldest satoshis first, which can help ensure that the receiver’s payments always confirm, although this has utility only in a few edge cases. The proliferation of Internet of Things (IoT) across various industries is also expected to play a crucial part in the uptake of these technologies.
