Zusammenfassung:	An apparatus for guaranteeing the integrity of a state database includes a memory for storing one or more instructions, a communication interface for communicating with one or more blockchain nodes and a processor. The processor is configured, by executing the stored one or more instructions, to receive a request to query for a state value, obtain a first state value by querying a state database in response to the request, forward the request to the one or more blockchain nodes to receive a second state value from the one or more blockchain nodes and compare the first state value with the second state value to determine integrity of a state value.
