The remote service is the main point of passage.
Core operation first depends on remote infrastructure availability.
OFFLINE FIRST · LOCAL WHEN POSSIBLE
Your documents remain accessible.
Gankpo prioritises local execution for suitable operations, then uses the network when transport, issuance or the trust model requires it.
LOCAL.gkpNETWORK WHEN NEEDED
01
Offline First does not mean “never connected”.
Local execution is preferred when the model allows it.
The network completes the journey for transport, synchronisation or required external evidence.
02
What can you do without the Internet?
Store a .gkp fileLocal
No network is required merely to store the file on chosen media.
Read structure and metadataLocal
When the application supports the relevant format version.
Check integrity and the primary signatureLocal
From the available bytes, fingerprint and public key.
Open a protected payloadLocal, conditional
Requires the right secret or access key; support varies by application.
Assess a trust chainHybrid
Local when useful anchors and evidence are available; otherwise an update may be required.
Establish a fresh revocation statusHybrid
Cached or embedded evidence may be checked locally; freshness may require synchronisation.
Obtain a trusted timestampConnected
An existing token may be validated locally; obtaining it relies on a TSA.
Prepare or read a .gksend envelopeLocal
Transport through a relay, messaging or another channel remains separate.
Issue or present a remote credentialGenerally connected
Issuer, Connect, OID4VCI and OID4VP exchanges depend on the journey and remote service.
This matrix describes architectural behaviour and its conditions. Exact availability depends on the application, platform, format and qualified version.

Autonomy without absolute claims.
Autonomy
Continue locally when connectivity is missing.
Privacy
Limit systematic transmission.
Resilience
Reduce the impact of central outages.
Control
Choose storage media.
Portability
Move the file through available mechanisms.
Continuity
Separate local access from trust services.
