1. A blockchain network system comprising:
a plurality of sensor devices; and
a blockchain network,
wherein the plurality of sensor devices are connected with each other via the blockchain network in a communicable manner, and sensor data acquired by the plurality of sensor devices are managed on the blockchain network in a distributed manner,
wherein each of the plurality of sensor devices include:
at least one processor configured to
sequentially acquire sensor data in real space on a frame-by-frame basis;
process the sensor data acquired by the plurality of sensor devices;
store the sensor data;
encrypt the sensor data obtained by the plurality of sensor devices; and
register the sensor data encrypted on the blockchain network,
wherein the at least one processor aggregates the sensor data acquired by the sensor device with a predetermined number of frame aggregations, and
wherein the at least one processor collectively encrypts the sensor data aggregated by the at least one processor with the predetermined number of frame aggregations.
