What are ordinals?
Ordinals are numbers, like this: 804766073970493. Every satoshi, which is ¹⁄₁₀₀₀₀₀₀₀₀ of a bitcoin, has an ordinal, and every ordinal has a satoshi. When a satoshi changes hands, so does its ordinal. There are a lot of satoshis, and so there are a lot of ordinals. Two quadrillion ninety-nine trillion nine hundred ninety-nine billion nine hundred ninety-seven million six hundred ninety thousand, to be precise.
