What is MOBI Trusted Trip?
A trip is a roaming entity’s — such as a person, smartphone, or electric vehicle (EV) battery — journey from one place to another. The trip is the basic unit of information for monetizing mobility in a services economy for consumers, providers, and infrastructure owners. For a trip to be useful to economic agents in a usage-based mobility payments system, it must be trusted by all parties in the transaction. MOBI defines a Trusted Trip as a trip whose attributes are validated/attested/certified by authorized entities/devices in the co-op decentralized network. The Trusted Trip combines identity and ubiety to enable a multitude of applications that advance smart mobility and sustainability.
- Decentralized Identifier (DID)/Verified Identity: characteristics asserted to uniquely distinguish a person, business, vehicle, part, or thing
- Ubiety: unique positions in space and time
- MOBI Trusted Trip: the combination of verified identity and ubiety certified through time
How Does the MOBI Community Validate and Leverage the Trusted Trip?
An important function of blockchain/DLT consortia is to establish alternative trust primitives which serve as public shared infrastructure for decentralized business networks. For MOBI and its members, the key primitive is the Trusted Trip. The Trusted Trip enables marginal cost pricing for decentralized mobility transactions in the New Economy of Movement. The Trusted Trip ensures that data can be trusted (tampered evident) when using a decentralized network — ensuring the value of the shared network is preserved.
How Can Third Parties Verify that a Roaming Entity Started or Completed a Trip in a Decentralized Network?
Verification requirements include:
- DIDs: verifier ID, user ID, vehicle ID, and device ID all properly registered in a network
- Physical Presence: verification of physical presence at A and B, where A and B may be geospatial locations, transponder reads, charging/fueling stations, or time/date stamps
- Physical Movement: verification of physical movement (or lack of movement) on particular travel segments between A and B, especially in MaaS
- Documents: verification of documents created during transport, especially in logistics (e.g. bill of lading, manifests, receipts)
MOBI Trusted Trip Certification
The basic interoperability requirements for a verifier to issue a standardized Trusted Trip Certificate within an automated business network include:
- Minimum dataset (proofs) with the essential information included in a Trusted Trip
- Unique trip identifier, which refers to a trip that is globally unique and verifiable
- Network of trust anchors needed to establish the authenticity and validity of certificates presented by certificate holders
Pay-As-You-Go Mobility and the MOBI Trusted Trip
MOBI Trusted Trip unlocks almost every imaginable use case for decentralized, usage-based mobility. Combining identity and ubiety, along with other data verified by a minimum set of industry-accepted “proofs” within a decentralized shared network, enables a multitude of applications that will advance smart, green mobility, and decarbonization.
Supply Chain and the MOBI Trusted Trip
MOBI Trusted Trip is also a key primitive for improving efficiency in the manufacturing and mobility services supply chain. Modern vehicles contain thousands of parts from hundreds of possible suppliers. The current supply chain uses primarily paper-based processes which means parts in transit are often hidden from the rest of the parties in the chain, making this current system lack transparency, and be prone to error and delays.
Tracking the part’s ubiety and identity as it travels through the supply chain reduces frictional inefficiencies, saves money, and ultimately results in safer, greener, and more affordable vehicles. MOBI Trusted Trip can be used to ensure parts traceability up and down the supply chain, which will enable scaling for a multitude of use cases such as parts recalls, authenticity, and ethical and sustainable labor practices.
Combining secure identity with trusted time-stamped locations creates a “Trusted Trip” and, for the first time, enables marginal cost pricing for many new classes of mobility transactions such as urban road tolling, meter-free parking, congestion management, carbon and pollution taxing, usage-based insurance, and many other usage-based Mobility as a Service (MaaS) applications. Together, these new transactions will comprise a multi-trillion-dollar ecosystem that we call the New Economy of Movement.
