Abstract: The present disclosure relates to a method for verifying a value stream along a transport route, wherein a plurality of field devices, each having at least one sensor and/or actuator for determining and/or monitoring at least one process variable and an electronic unit, are arranged along the transport route and generate corresponding data, or for verifying the value stream of at least one product in warehouse stock, wherein a first service platform is used, via which a plurality of participant nodes each with at least one database have a communication connection to one another according to a distributed ledger or blockchain technology.

Abstract: The present disclosure relates to a method for ensuring the authenticity of a field device. The method includes a step of assigning a unique authentic identification feature to the field device or providing the field device with a unique authentic identification feature. The method also includes steps of transmitting ACTUAL identification data to a participant node which transmits the ACTUAL identification data to the other participant nodes in a transaction, validating the transaction by the participant nodes, and creating a data block containing the transaction, wherein the data block is transmitted to each of the participant nodes. The method also includes verifying the data block by all participant nodes, storing the validated data block in the databases, comparing the ACTUAL identification data with corresponding TARGET identification data or original identification data from an authentication point, and generating a response containing the result of the comparison.

Abstract: The invention relates to a method for determining or monitoring an automation technology process variable with at least one field device. The method comprises the following method steps: receiving guidelines relating to: access to the data of the field device; the number of times the data of the field device is accessed; or a request for data of the field device. The method also includes steps of storing the data of the field device in an encoded manner in a first service platform that is connected to a second service platform and receiving a request for data at the second service platform, wherein the second service platform accesses the guidelines. The method also includes steps of providing the data according to the guidelines via a first transaction in pre-defined cycles or all at once and generating a request for payment for the data made available according to the guidelines.

Abstract: The invention relates to a method for verifying a value stream along a transport route (TS), in particular along a pipeline or a production line, wherein a plurality of field devices (F), each having at least one sensor (S) and/or actuator for determining and/or monitoring at least one process variable and an electronic unit (EE), are arranged along the transport route (TS) and generate corresponding data (DAT), or for verifying the value stream of at least one product in warehouse stock, wherein a first service platform (SP1) is used, via which a plurality of participant nodes (TK) each with at least one database (DB) have a communication connection to one another according to a distributed ledger or the blockchain technology.
