Each token of the transaction system has at least one token value and one private part of a token-individual key pair acting as token elements. The method comprises the following method steps: receiving, in a token reference register of the transaction system, a registration request from a sequence of registration requests, each registration request of the sequence having at least one token reference; using a verification unit of the token reference register to verify whether the at least one token reference contained in the received registration request can be uniquely assigned to a token of the transaction system; storing the at least one token reference in a memory unit of the token reference register in order to register the token uniquely assigned to this token reference in the transaction system if it is established in the verification step that the at least one token reference of the received register request can be uniquely assigned to a token of the transaction system and if the token reference is not yet stored in the token reference register. In the receiving step, the registration requests are received in the token reference register as a sequence of registration requests. In the verification and storage steps, the registration requests are processed in the token reference register as a sequence of registration requests.
