About UUID Generator
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information in computer systems. Because UUIDs have a very high level of uniqueness, they can be generated independently without contact with a central registration authority or coordination between systems.
What is a UUID v4?
A Version 4 UUID is generated completely randomly. Out of the 128 bits in a UUID, 122 bits are random, while 6 bits are used to declare the version and variant. This leaves a total of 2^122 possible variations, which makes collision practically impossible. For context, to have a 50% chance of a collision, you would need to generate 1 billion UUIDs every second for about 85 years.
