The invention also relates to a method for ammunition monitoring, wherein shooting data on the firing of at least one shot from a firearm (3), achieved by the discharge of a cartridge loaded into the firearm, is recorded by at least one fired-shot sensor (2) assigned to the firearm (3) and stored in a shooting log device (9). ## Claims ### Claim 1 An ammunition monitoring system with at least one fired-shot sensor assignable to a firearm and with a shooting log device, wherein the ammunition monitoring system is designed to record as shooting data, by means of the fired-shot sensor, the firing of at least one shot from the firearm, achievable by the discharge of a cartridge loaded into the firearm, and to store the recorded shooting data in the shooting log device, characterized in that the shooting log device has a blockchain data structure for filing of the shooting data, wherein the blockchain data structure has an accounting system for the cartridge which comprises a digital copy of the cartridge and covers the period at least from delivery, in particular from manufacture of the cartridge, to the shot being fired, wherein actual expending of the cartridge is determinable using the blockchain data structure based on shooting data and is loggable by irrevocable transfer of the digital copy of the cartridge into a blacklist ammunition wallet in tamper-proof manner. ### Claim 2 (depends on 1) The ammunition monitoring system according to claim 1, characterized in that for recording of the shooting data the at least one fired-shot sensor, in particular several fired-shot sensors, is, in particular are, mountable on or mounted on the firearm. ### Claim 3 (depends on 1) The ammunition monitoring system according to claim 1, characterized in that the fired-shot sensor has an acceleration sensor, a vibration sensor, a position sensor, a temperature sensor, a gyroscope, an angle sensor, an orientation sensor and/or an acoustic sensor, such that the fired-shot sensor is designed to record as shooting data at least the firing of the shot, in particular at least the firing of a sequence of shots, a number of shots, a firing angle and/or a firing position. ### Claim 4 (depends on 1) The ammunition monitoring system according to claim 1, characterized in that the fired-shot sensor has at least one storage device for at least temporary storage of the recorded shooting data. ### Claim 5 (depends on 1) The ammunition monitoring system according to claim 1, characterized in that the shooting log device is designed as a data server, in particular as a cloud-based data server, wherein the fired-shot sensor is designed to transmit the shooting data to the data server in wireless or wired manner. ### Claim 6 (depends on 1) The ammunition monitoring system according to claim 1, characterized in that the ammunition monitoring system has a mobile communication device, wherein the fired-shot sensor transmits the shooting data to the mobile communication device in wireless or wired manner, and that the mobile communication device comprises the shooting log device or transmits the shooting data to the shooting log device in wireless or wired manner. ### Claim 7 (depends on 1) The ammunition monitoring system according to claim 1, characterized in that the ammunition monitoring system has a plurality of further fired-shot sensors assignable to further firearms, wherein the firing of shots from the further firearms is recordable as shooting data by means of the further fired-shot sensors and storable in the shooting log device. ### Claim 8 A method for ammunition monitoring, in particular using an ammunition monitoring system according to any of the above claims, wherein shooting data on the firing of at least one shot from a firearm, achieved by the firing of a cartridge loaded into the firearm, is recorded by at least one fired-shot sensor assigned to the firearm and stored in a shooting log device, characterized in that the shooting data is stored in a blockchain data structure, wherein accounting for the cartridge is conducted in the blockchain data structure, wherein a digital copy of the cartridge is generated for accounting purposes, and wherein accounting covers the period at least from delivery, in particular from manufacture of the cartridge, to the shot being fired, wherein actual expending of the cartridge is determined using the blockchain data structure based on the shooting data and is logged by irrevocable transfer of the digital copy of the cartridge into a blacklist ammunition wallet in tamper-proof manner. ### Claim 9 (depends on 8) The method according to claim 8, characterized in that the shooting data comprises the number, direction and/or position of the shot(s) fired. ### Claim 10 (depends on 8) The method according to claim 8, characterized in that the cartridge is assigned to at least one ammunition wallet for accounting purposes. ### Claim 11 (depends on 8) The method according to claim 8, characterized in that the shooting data is transmitted from the fired-shot sensor to the shooting log device in wireless or wired manner using a mobile communication device. ### Claim 12 (depends on 8) The method according to claim 8, characterized in that the shooting log device records firearm data of the firearm and assigns the shooting data and the firearm data to one another. ### Claim 13 (depends on 8) The method according to claim 8, characterized in that the shooting log device performs an integrity test on the location of the cartridge.
