Abstract
A decentralized distributed ledger-type database comprises a plurality of subscriber nodes, comprising validation-capable subscriber nodes, and an automation field device with an electronic unit (running a distributed ledger software stack). The field device generates measurement values and/or calibration certificates requiring verification. The field device operates as a light node of the decentralized database after running the distributed ledger software stack and transmits data to the decentralized database via the communication network and writes it in encrypted form into the database. The validation-capable subscriber nodes validate the transmitted data, and the decentralized database stores the data if at least a specified proportion of the validation-capable subscriber nodes successfully validate the data. Read-authorized subscriber nodes decrypt and read the stored data in the decentralized database, with the database storing and running smart contracts. The calibration certificates include information about a start and end of a validity period of the certificates.
