Business result

What you receive.

The business receives only the requested threshold and true or false. Alentra processes the date of birth to calculate it.

Evidence boundary

What remains provable.

The identity and wallet presentation remain encrypted in the immutable audit; the business-facing result remains redacted.

Where it fits

A verb,
not a vertical.

Alentra keeps primitives horizontal. Your product owns the industry-specific policy around them.
