V3. Vehicle Registration Workflow – The process of registering a vehicle through the interaction of a vehicle (and typically other stakeholders such as the vehicle dealer or owner) with an authority.

V4. Vehicle-to-Grid (V2G) – Vehicle-to-Grid refers to a type of use case that centers around the coordinated, either uni- or bi-directional energy exchange between vehicles and the grid.

V5. Verifier – Device/user/entity/application that receives a VC from a holder to verify the credentials presented by the holder in order to provide goods/services to the holder.

V6. Verifiable Credential – The W3C Verifiable Credentials Standard defines Verifiable Credentials as “a part of our daily lives; driver’s licenses are used to assert that we are capable of operating a motor vehicle, university degrees can be used to assert our level of education, and government-issued passports enable us to travel between countries. This specification provides a mechanism to express these sorts of credentials on the Web in a way that is cryptographically secure, privacy-respecting, and machine-verifiable.

V7. Verifiable Data Registry – It plays a role in mediating the creation and verification of identifiers, keys, VC schemas, revocation registries, issuer of public keys, etc. It may be a trusted database, government identity database, or distributed ledger/blockchain.

V8. Verifiable Presentation (VP) – A verifiable presentation is a tamper-evident presentation encoded in such a way that authorship of the data can be trusted after a process of cryptographic verification. Certain types of verifiable presentations might contain data that is synthesized from, but do not contain, the original verifiable credentials (for example, zero-knowledge proofs). (Source: W3C, 2022)

V9. Verifiable Presentation (VP) by Holders – A holder sends a message set to a verifier, depending on the use case, various attributes about an activity/trip occurred along with proofs of issuer and holder.

V10. Vehicle Identification Number (VIN) – A unique code, including a serial number, used by the automotive industry to identify individual motor vehicles, towed vehicles, motorcycles, scooters, and mopeds, as defined in ISO 3779 (content and structure).

W

W1. Waterfall Structure – Waterfall payment structures require that higher-tiered creditors receive interest and principal payments while lower-tiered creditors receive principal payments only after the higher-tiered creditors are paid back in full. Debtors typically structure these payments into such tranches to prioritize the highest-principal loans first because they are also likely the most expensive.

W2. Web3 — Web3, or the decentralized web, is the next generation of the internet. It promotes data spaces interoperability for security and transparency, user control, and direct transactions.

W3. World Wide Web Consortium (W3C) – The World Wide Web Consortium is the main international standards organization for the World Wide Web. Founded in 1994 and led by Tim Berners-Lee, the consortium is made up of member organizations that maintain full-time staff working together in the development of standards for the World Wide Web.

Z

Z1. Zero-Knowledge Proof (ZKP) – In cryptography, a zero-knowledge proof is a method by which one entity (the prover, assumed to be computationally powerful) can prove to another party (the verifier, assumed to be computationally restricted) that a particular statement is true without revealing any further information.
