Design principles

The constraints that keep independent verification possible.

These are system constraints, not product features. CERTCRYPT is defined by the conditions required for independent verification to remain possible over time, and by what the system deliberately refuses to do.

Core principles

Each principle protects a condition required for independent verification to remain possible without data custody, institutional dependence, or system-level tracking.

Zero-data by design
The system avoids storing documents, identities, or operational records.
Verification depends on certificates and rules, not on retained platform data.
Proof without data custody
Verification does not require data custody or access to internal systems.
It relies on the certificate, the original material presented by the verifier, and the formal rules instead of platform-held data.
Unlinkability
Certificates are designed to not expose stable references that enable cross-certificate correlation or reconstructable subject activity.
The model preserves formal verifiability without turning certificates into tracking artifacts across the system.
Deterministic verification
Verification produces the same result regardless of who performs it.
Given the same inputs and rules, outcomes converge.
Institutional independence
Verification does not depend on the continued existence of an issuing entity.
The system avoids conditions that require institutional continuity.
Infrastructure neutrality
The certification model is independent of specific platforms, providers, or infrastructures.
Verification rules remain stable across environments.
Interpretation boundaries
CERTCRYPT does not interpret legal meaning or semantic truth.
Its role is to preserve verifiability under formal rules.
