What is a UUID used for?
UUIDs (Universally Unique Identifiers) are used as unique IDs for database records, API tokens, distributed systems, and anywhere you need a unique identifier without central coordination.
Are UUID v4 collisions possible?
Theoretically yes, but the probability is astronomically low. With 122 bits of randomness, generating 103 trillion UUIDs gives only a 50% chance of a single collision. For any practical use, collisions are impossible.
