UUID in a nutshell

Because you might be a little confused about what a UUID actually is.

Version 1

A version 1 UUID is a unique identifier that is generated from a timestamp and the MAC address of the computer, ensuring uniqueness. However, because the MAC address is exposed, it poses potential privacy and security risks.Read more about v1

Version 4

A version 4 UUID is a unique identifier generated from random numbers. This makes it highly unlikely that any two UUIDs will ever be the same. The version 4 UUIDs generated by this site use a secure random number generator for maximum security.Read more about v4

Version 7

A version 7 UUID is a time-ordered UUID that encodes a Unix timestamp with millisecond precision in its most significant 48 bits. It uses 6 bits for version and variant, with the remaining 74 bits randomly generated. The sequential nature of UUIDv7 improves database performance by addressing the index locality issue, unlike the random UUIDv4.
