4、 features. The thesis has assessed blockchain technology for implementation with the Bosch Transport Data Logger, TDL. The TDL is a sensor-equipped logging device with a companion smartphone app. The device is fastened to packages during transportation and logs how the packages have been handled whi

The two main types of blockchain technology, permissionless and permissioned, are found to have inherent trade-offs between open/closed participation and poor/good performance
6、. Hyperledger Fabric, most mature of the permissioned blockchain systems, was used to build a TDL Blockchain System proof of concept. Log data and other information from and about the TDL devices, transferred by the transport company employees using the companion app, are stored on the blockchain. Generally, just saving sensor values is not enough to accomplish anything. To give credence to the logged data and to be able confidently to act upon it, the data must be made trustworthy. In an environment where
