  > UUID Version 2 (v2) is reserved for security IDs with no known details.

  Only no known details if the only document you're reading is the notoriously poorly-specified RFC. Here you go: https://pubs.opengroup.org/onlinepubs/9696989899/chap5.htm#t...

  There are also “version 0” UUIDs that you are very unlikely to ever come across but should be noted because they are the source of the reserved bits that allow the other “versions” to be specified. Read my research about them here in my UUID library: https://github.com/okeeblow/DistorteD/blob/NEW%E2%80%85SENSA...

  Words that we do not want to appear in Sqids IDs

  

  Sqids[1] might fit the bill for you - the IDs it produces are much shorter than UUIDs, however they're not universally unique - they're generated from an integer sequence.

  A tiny (124 bytes), secure, URL-friendly, unique string ID generator for JavaScript

• snowflake

  Discontinued Snowflake is a network service for generating unique ID numbers at high scale with some simple guarantees.

  

  If you're not distributed, use an incrementing integer.

  If you're distributed, look into vector clocks[1] or snowflake[2]

  𝗗𝗮𝘁𝗮, 𝗔𝗻𝗮𝗹𝘆𝘁𝗶𝗰𝘀 & 𝗔𝗜. Modern alternative to Snowflake. Cost-effective and simple for massive-scale analytics. https://databend.com

  

  UUID v7's timestamp is a game-changer for Databend. We're using it to quickly locate metadata files on AWS S3 by timestamp, making operations like vacuuming much faster.

  The UUID Standard.

  

  We are starting work on an informational RFC that will help folks understand those.

  See https://github.com/yocto/draft-yocto-uuid if you want to add to some discussions and/or review text. We are still a bit early into the stages but I hope to have some progress soon.

  New UUID Encoding Techniques

  

  We are working on standardizing an alternate encoding technique for the 128 bit UUID so it can have a shorter text form.
