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:
