# Traits

A Natalia's traits and visual style are dynamically determined by the block number of the Bitcoin block it's found in. \
\
While Natalias are only found in blocks where the hex value of the "bits" field contains `fed`, the art itself is dynamically generated based on the block number and the patterns found within it.

Jump into the next pages to learn about the different traits & styles of Natalias, and what patterns result in what values!
