GUID / UUID v8 is a flexible, application-defined identifier format that provides a standardized container for custom schemes. Unlike other GUID / UUID versions, v8 does not prescribe how most bits are generated, allowing applications to define their own internal structure while producing valid GUID / UUID strings.

GUID / UUID v8 is designed for advanced use cases where predefined versions (v4 and v7) don't fit. It requires careful design and documentation, as uniqueness and ordering guarantees depend entirely on the application's implementation.
