$PI Pi (π) is an irrational number, which means its decimal digits never end and never repeat in a specific pattern.

Mathematicians have calculated it to more than 100 trillion digits using supercomputers, but we are still far from "solving it," because it has no end.
For context, NASA uses only 15 digits of Pi for its most precise interplanetary calculations. Everything beyond that is purely mathematical curiosity, not a practical necessity.

Pi's infinite, patternless nature makes it a favorite symbol for concepts that resist simple boundaries, which is fitting given how often the crypto community borrows it to represent something similarly limitless.
