The probability of two GUIDs matching is extremely low, with odds of 1 in 2^122.
Guid Smash visualizes the improbability by comparing new GUIDs to a target GUID.
At a rate of 400,000 GUIDs per second, a match is expected in 421 quintillion years.
The target GUID is '6e197264-d14b-44df-af98-39aac5681791'.
As of July 20, 2025, over 1.1 trillion GUIDs have been checked at ~469,022 per second.
A table shows decreasing matches as the prefix length increases, with no full matches yet.
