Abstract
Provided is a method for operating a distributed database system having distributed node devices for providing interlinked data blocks, in particular in the style of a blockchain, that document transactions between subscribers, wherein transactions between subscribers are protected by transaction data and a cryptographic signature process, involves the cryptographic signature process being defined for each transaction in order to protect the respective transaction, wherein signature information identifying the defined cryptographic signature process is part of the transaction or part of a performance request for the transaction. For each transaction, signature data are then calculated using the defined cryptographic signature process for at least some of the transaction data or the hash value thereof, and the signature data are added to the transaction data.
