Figure 4. Broof modular structure Using P2P, transactions can be made with other nodes, and block data can be shared. The rule module can be used to confirm smart contracts and transaction and block compatibility. A platform that meets different requirements can be configured as necessary by changing modules. A RPC module is used as an interface for outside linkages. The cache module uses a least recently used algorithm to manage the cache and enable effective processing of data. The mining module can provide solution algorithms for rapid responses to forks, enabling high-speed transaction processing. 3. Usage Example Confirmation of system operation was made at an Italian restaurant located in Tokyo. Mounting of the dongle while the application was running enabled the user to watch a set of videos introducing the ingredients used in cooking, including information about the production sites of vegetables and wines used at the restaurant and images detailing the processes from production to delivery. Figure 5 shows the system in operation at the restaurant. Figure 5. Use of the system at a restaurant Operation confirmation was performed following the procedures described below. The first video concerning a specific menu item is readied, and the first dongle corresponding to this first video is prepared. The second video concerning a specific menu item is then prepared, along with the second dongle corresponding to this second J.Suzuki etal. / System forMotivatingEthicalConsumptionBehavior 167
