About UUIDs
Version 4 (Random)
The most commonly used UUID version. Generated using random or pseudo-random numbers. Has a very low probability of collision.
Version 1 (Timestamp)
Based on timestamp and MAC address. Guarantees uniqueness across time but may reveal information about when and where it was generated.
UUIDs are 128-bit identifiers standardized by RFC 4122. They're designed to be unique across space and time without requiring a central authority.
