A device for adding equipment data of a piece of equipment into a distributed database system includes a first communication interface designed to receive database configuration information from the distributed database system, a second communication interface coupled to the piece of equipment and designed to receive equipment data a configuration module designed to select at least one configuration parameter for configuring a data providing module, test at least one selected configuration parameter on the basis of the database configuration information, output the test result, and configure the data providing module, an identification module designed to provide identification information, a registration module designed to register the piece of equipment on the basis of the identification information for the distributed database system, and a data providing module designed to add the equipment data with respect to the identification information into the distributed database.

Device and method for adding equipment data into a distributed database system

A system and a method for writing and retrieval of data in a distributed ledger is provided and includes receiving a first dataset including data entries between a start instant and an end instant of a current regular time interval from nodes that are online and recording in a current main block; and receiving one or more second datasets including data entries between respective start instants, preceding the current regular time interval, and respective end instants of corresponding one or more given regular time intervals, from nodes that were offline at the respective end instants of the corresponding one or more given regular time intervals and are online then and recording in corresponding one or more current temporal side blocks; and pegging the temporal side blocks to the main block, and committing to the distributed ledger.

System and method for writing and retrieval of data in a distributed ledger

In a computer-implemented method for storing data in a network of linked computing units () using a distributed transaction database (GDB), a distributed transaction database (GDB) in the form of a distributed graph database formed using nodes is used, and data is stored in at least one node (N) of the graph database, wherein the node (N) is stored using a real sub-quantity of the computing units () of the network. The computer program product can be loaded directly into a storage device of an electronic computing unit () and has program means in order to early out the steps of the method when the program is ran in a computing unit. The network of linked computing units () stores a distributed transaction database (GDB) in the form of a distributed graph database comprising nodes (N) in which data is stored according to such a method.

Provided is a computer-implemented method and system for checking anonymisation of data. Anonymized data are analysed by means of a smart contract process based on data privacy rules automatically raising a flag in case of an anomaly. The smart contract is governed in a decentralized manner where anodes of distributed database can verify the rules specified in the smart contract and/or assess an anomalous situation. To this end, test data are generated at the data source by applying the data privacy rules to the original data. The test data are checked against the anonymized data and depending on the check result metadata are generated. The metadata are provided to nodes of a distributed database for further verification.

Various examples of the disclosure generally pertain to storing, in a distributed ledger and in association with one or more transactions, one or more identifiers of owners of respective smart contracts. Various examples of the disclosure relate to deleting transactions associated with a given party as owner upon receiving a withdrawal request of the given party.

Deleting transactions from a distributed ledger

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.
