About UUIDs
A UUID (Universally Unique Identifier) or GUID (Globally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique across space and time. UUIDs are typically represented as 32 hexadecimal digits, displayed in five groups separated by hyphens.
The standard format looks like: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
UUIDs are designed to be generated without a central authority and still be practically unique, making them ideal for distributed systems.
