Query: A Distributed Ledger Based Infrastructure for Smart Transportation
  System and Social Good   This paper presents a system architecture to promote the development of smart
transportation systems. Thanks to the use of distributed ledgers and related
technologies, it is possible to create, store and share data generated by users
through their sensors, while moving. In particular, IOTA and IPFS are used to
store and certify data (and their related metadata) coming from sensors or by
the users themselves. Ethereum is exploited as the smart contract platform that
coordinates the data sharing and provisioning. The necessary privacy guarantees
are provided by the usage of Zero Knowledge Proof. We show some results
obtained from some use case scenarios that demonstrate how such technologies
can be integrated to build novel smart services and to promote social good in
user mobility.
