Abstract
A method for obtaining a valid global state for a distributed database, wherein the distributed database includes main nodes storing a complete dataset, and a plurality of subsets of nodes configured to store a part of the dataset, including: a. receiving a request for providing a valid global state of the distributed database, b. determining a first local state for each subset based on status information of nodes of the respective subset regarding the respective part of the dataset, c. combining these first local states of all subsets to a first combined state, d. determining a global state by the main nodes based on status information of the main nodes regarding the stored dataset, e. verifying the first combined state by matching the first combined state with the global state and f. outputting the first combined state as valid global state for the distributed database depending on the verification.
