The emergence of Mobility-as-a-Service (MaaS) presents a promising solution to meet the growing demand for usage-based business models and effectively address pressing challenges in mobility and sustainability. However, most MaaS services today are offered by siloed centralized platforms, which lack the interoperability needed to connect distinct mobility services. These platforms also fall short of providing data privacy for riders and providers. To this end, MOBI created Citopia MaaS, a federated Web3 marketplace which provides a secure and easy-to-use mobile app for riders to seamlessly plan or book multimodal trips from different service providers with itinerary, ticketing, and payments all in one place. Citopia MaaS is designed to allow riders to select their trip preferences among fastest, cheapest, least number of transfers, and greenest routes; and choose their preferred mode(s) of transit such as bus, bike-as-a-service, and more. Citopia MaaS includes a web interface that enables service providers to securely onboard assets and offer services to riders via simple API integrations. Citopia uses the blockchain-based Integrated Trust Network (ITN) as the trust anchor for decentralized identity management. Citopia MaaS leverages state of the art Web3 technologies to enable a seamless and secure MaaS experience while redefining data privacy for riders and service providers. These technologies include Self-Sovereign Digital Twins (SSDTs)World Wide Web Consortium (W3C) Verifiable Credentials (VCs) and Decentralized Identifiers (DIDs), and Zero-Knowledge Proofs (ZKPs). DIDs allow the SSDTs™ of riders, vehicles, service providers, and other entities to communicate and transact with each other via VCs. VCs are coupled with ZKPs to add greater data privacy so that riders have full ownership and control of their Personally Identifiable Information (PII). This Citopia MaaS Transit IDEA project successfully demonstrated seamless MaaS planning, booking, trip execution, and payments by leveraging Web3 technologies and ensuring rider and service provider data privacy.
