Communication network node, methods, and a mobile terminal
The present disclosure provides a communication network node for providing data to a distributed ledger, wherein the node has circuitry configured to perform at least one of provide verification of input data which is used as input to a smart contract, provide verification whether output data, which is based on an output from a smart contract, is correctly received at a predetermined dev.
1. A communication network node for providing data to a distributed ledger, wherein the node comprises circuitry configured to:
bind a unique user-based identification and a mobile terminal based identification, wherein the unique user-based identification is a user account and the mobile terminal based identification is a plurality of unique cellular identifications selected by a user,
provide verification of input data which is used as input to a smart contract, wherein the input data are verified based on sensor data, the sensor data identifying a user,
in a case that the input data is verified, transmit a trigger for causing execution of a smart contract,
verify that a sensor providing the sensor data is an authentic data source without knowing the unique user-based identification based only on a certificate received from a terminal device that certifies the sensor providing the sensor data, and
provide verification whether output data, which is based on an output from the smart contract, is correctly received at a predetermined device, wherein the output data is a ticket state being open, in use, or closed based on a check-in event trigger changing the ticket state from open to in use or a check-out event trigger changing the ticket state from in use to closed.
2. The communication network node of claim 1 , wherein the sensor data are provided by at least one sensor included in a mobile terminal of the user.
3. The communication network node of claim 1 , wherein the sensor data are provided by at least one sensor detecting a user.
4. The communication network node of claim 1 , wherein the sensor data include location data or biometric data.
5. The communication network node of claim 4 , wherein the location data are transmitted to a location server for verification.
6. The communication network node of claim 4 , wherein the biometric data are transmitted to a biometric data server for verification.
7. The communication network node of claim 1 , wherein the circuitry is further configured to receive or transmit data based on a data integrity functionality.
8. The communication network node of claim 7 , wherein the data integrity functionality is based on at least one of: hash function, digital signature, block stream algorithm.

15. The communication network node of claim 1 , wherein the certificate is an X.509 certificate.
16. A method for operating a smart contract, wherein the smart contract has at least two different states, the method comprising:
binding a unique user-based identification and a mobile terminal based identification, wherein the unique user-based identification is a user account and the mobile terminal based identification is a plurality of unique cellular identifications selected by a user;
providing verification of input data which is used as input to the smart contract, wherein the input data are verified based on sensor data, the sensor data identifying a user;
in a case that the input data is verified, transmitting a trigger for causing execution of a smart contract;
verifying that a sensor providing the sensor data is an authentic data source without knowing the unique user-based identification based only on a certificate received from a terminal device that certifies the sensor providing the sensor data;
changing a state of the smart contract in response to receiving a trigger; and
providing verification whether output data, which is based on an output from a smart contract, is correctly received at a predetermined device, wherein the output data is a ticket state being open, in use, or closed based on a check-in event trigger changing the ticket state from open to in use or a check-out event trigger changing the ticket state from in use to closed.
