Long-Term Verifiability.

Digital Witness relies on:

• ✓Open cryptographic standards (SHA-256, Ed25519).
• ✓Publicly documented verification methods.
• ✓No proprietary or opaque validation logic.

As a result, verification does not depend on:

• ×A specific vendor.
• ×A specific software version.
• ×Continued operation of internal systems.

Year  0:  Capture & Witness            ✓
Year  5:  Independent Verification     ✓
Year 15:  Independent Verification     ✓
Year 30:  Independent Verification     ✓

As long as standard cryptographic tools exist, verification remains possible.

This makes Digital Witness suitable for:

• •Intellectual property priority claims.
• •Long-term contract archives.
• •Regulatory audit trails.
• •Public-sector records.
• •Litigation evidence with extended timelines.

Digital Witness certificates are designed for long-term evidentiary use. Verification relies on open, well-established cryptographic standards rather than proprietary formats or vendor-specific systems — so evidence can be independently verified years or decades after capture.

Long-term verification does not depend on continued operation of the issuing platform, specific software versions, or internal system access. As long as standard cryptographic tools remain available, the integrity of the evidence can be confirmed using the original file and the certificate.

This makes Digital Witness suitable for use in legal archives, intellectual property documentation, regulatory compliance, and other contexts where evidentiary records must remain verifiable over extended periods.
