What is MOBI Trusted Trip (MTT)?

A trip is the journey of a roaming entity— such as a person, smartphone, or electric vehicle (EV) battery — 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 trips involving usage-based transactions (e.g. road usage charging or metered parking), it is crucial that the data associated with those trips can be validated by all parties involved in the transaction(s).

MOBI defines a Trusted Trip as a trip whose attributes are certified by ecosystem stakeholders in a federated network. The Trusted Trip combines identity and ubiety to enable a multitude of mobility applications in Web3.

An important function of blockchain/DLT consortia is to establish trust primitives which serve as public shared infrastructure for decentralized business networks. For MOBI and its members, the key primitive is the Trusted Trip. MTT enables marginal cost pricing for decentralized services and ensures trip data can be trusted (tamper-evident) when using Web3 applications.

Combining secure decentralized identity with trusted time-stamped location will enable the creation of trusted multiparty track-and-trace applications and scale use cases such as battery passport, supply chain track and trace, 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.

MTT Verification Requirements

Verification of an MTT involves four key components:

  • Decentralized Identifiers (DIDs): Verifier DID, user DID, vehicle DID, device DID, etc., all properly registered in a network
  • Physical Presence: 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: Physical movement (or lack of movement) on particular travel segments between A and B
  • Documents: Documents created during transport, especially in logistics (e.g. bill of lading, manifests, receipts)

MOBI Trusted Trip Certification

The basic interoperability requirements for an entity to issue a standardized MOBI Trusted Trip Verifiable Credential (MTTVC) 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 to establish the authenticity and validity of VCs presented by VC holders

MTT Unlocks Pay-As-You-Go Mobility

MTT unlocks countless use cases for decentralized, usage-based mobility. The ability to verify identity and ubiety in a secure and privacy-preserving manner will enable a multitude of applications for smarter, greener mobility — revolutionizing the way we move, communicate, and transact. The MOBI community is currently exploring a number of applications, including:

MTT Enables Supply Chain Track-and-Trace

MTT is also a key primitive for improving supply chain efficiency. Trusted multiparty track-and-trace systems are needed to effectively manage assets in the value chain, enhance interoperability between stakeholders, and empower consumers to make informed purchasing decisions with confidence.

Tracking a part’s ubiety and identity across the value chain reduces frictional inefficiencies, saves money, and ultimately results in safer, greener, and more affordable products. MTT 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 battery passports, parts recalls, authenticity, and ethical and sustainable labor practices.
