Ordinal Theory Overview ======================= Ordinals are a numbering scheme for satoshis that allows tracking and transferring individual sats. These numbers are called [ordinal numbers](https://ordinals.com). Satoshis are numbered in the order in which they're mined, and transferred from transaction inputs to transaction outputs first-in-first-out. Both the numbering scheme and the transfer scheme rely on *order*, the numbering scheme on the *order* in which satoshis are mined, and the transfer scheme on the *order* of transaction inputs and outputs. Thus the name, *ordinals*. Technical details are available in [the BIP](https://github.com/ordinals/ord/blob/master/bip.mediawiki). Ordinal theory does not require a separate token, another blockchain, or any changes to Bitcoin. It works right now. Ordinal numbers have a few different representations: - *Integer notation*: [`2099994106992659`](https://ordinals.com/sat/2099994106992659) The ordinal number, assigned according to the order in which the satoshi was
