What is UUID?
UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify objects in computer systems. Without the need for a central authority, the probability of a UUID generated anywhere colliding with one generated elsewhere is practically zero.
UUID v4 Features
The Version 4 UUIDs generated by this tool are based on completely random numbers. The probability of a collision in a 128-bit value set is so low that even if you generated 1 billion UUIDs every second, you might have to wait 100 years to see a collision. This makes it a perfect identifier for distributed systems.
