What Makes Version 1 UUIDs Unique?
Version 1 UUIDs combine the timestamp with the MAC address of the generating device to ensure uniqueness. This timestamp tracks time down to 100-nanosecond intervals since October 15, 1582. Additionally, the clock sequence adds extra uniqueness, especially in cases where multiple UUIDs are generated quickly.
With up to 18 sextillion unique UUIDs possible per node, collisions are extremely rare, making Version 1 a reliable option for generating unique identifiers.
If you're looking for an alternative that allows for sorted UUIDs by creation time, consider exploring our Version 6 UUID generator, which is built on similar principles but offers enhanced sorting functionality.
