ROOTKey processes and anchors data through a set of formally defined protocols. Each protocol defines how data is anchored (on-chain vs. off-chain vs. hybrid) and where it is processed (sovereignty tier). These two dimensions together determine the auditability, throughput, cost, and regulatory fit of an integration.

​
Protocol Naming - RKP

All ROOTKey protocols follow a standardised naming convention:
RKP-N - base protocol · RKP-N Enhanced EU - EU cloud sovereignty · RKP-N Sovereign EU - full EU sovereignty
