Atomically Unique Identifier (AUID)

The Atomically Unique Identifier (AUID) system is the ID generation mechanism used within the P.A.I.N. Ecosystem.

Overview

The AUID system generates unique identifiers with 2^256 possible combinations, a number large enough to theoretically account for nearly every atom in the observable universe (approximately 10^80 atoms). This provides a significantly larger identifier space compared to UUID v4, which offers 2^128 combinations.

Format

AUIDs are formatted to be user-friendly and consistent with existing ID systems:

[a-f0-9]{16}-[a-f0-9]{16}-[a-f0-9]{16}-[a-f0-9]{16}

This format consists of four 16-character segments of hexadecimal digits (a-f0-9), separated by hyphens, making them easy to read and use in various applications.

Advantages

• Large Identifier Space: The 2^256 combinations reduce the likelihood of ID collisions to an extremely low level, even at scale.
• Familiar Format: The AUID format is similar to other commonly used ID systems, facilitating straightforward adoption.
• Long-Term Reliability: The vast number of possible IDs makes the system suitable for applications requiring long-term uniqueness and high-volume ID generation.

Usage

AUIDs can be used for any personal or commercial purpose.
