About UUIDs

UUIDs are unique identifiers that are used in software development to identify resources. UUIDs are 128-bit numbers represented as 32 hexadecimal digits separated by hyphens. Their uniqueness and low probability of duplication make them ideal for use in distributed systems.

UUIDs are commonly used in databases, APIs, and other systems to uniquely identify resources. They are also used in various programming languages and frameworks to generate unique identifiers.

About UUID v4

UUID v4 is one of the four versions of UUIDs defined in RFC 4122. It is a randomly generated UUID that is based on random numbers. UUID v4 is the most commonly used version of UUIDs and is suitable for most use cases.

UUIDs v4 are not guaranteed to be unique, but the probability of generating duplicate UUIDs is extremely low and can usually be ignored.
