The Universal Digital Vehicle Passport (UDVP) is a trust infrastructure designed to create a tamper-proof vehicle history, shared across the automotive ecosystem.
Each vehicle is assigned a unique digital identity, recording key lifecycle events (mileage, maintenance, accidents, ownership) in an immutable and verifiable manner.
The system relies on an enterprise-grade blockchain used as a background proof layer, fully invisible to end users.
The objective is to reduce fraud, restore trust, and improve efficiency in the automotive and used-vehicle markets.
How UDVP Uses VTHO – Concrete Operational Explanation
- Role of VTHO in the UDVP Architecture
In the Universal Digital Vehicle Passport (UDVP), VTHO is the operational cost unit that enables trusted vehicle lifecycle events to be anchored on the VeChainThor blockchain.
VTHO is not a revenue mechanism and not visible to end users.
It functions as a consumable infrastructure resource, comparable to transaction fees or API usage credits in traditional systems.
- What Actions Consume VTHO?
VTHO is consumed only when a trusted event is written to the blockchain.
Examples of UDVP write events:
certified mileage update,
maintenance or repair record,
parts replacement confirmation,
insurance claim or accident declaration,
ownership transfer,
manufacturer recall registration.
Each event:
is validated off-chain,
is submitted by a certified actor,
anchors a cryptographic proof on-chain,
consumes a predefined amount of VTHO.
Reading or consulting vehicle data does not consume VTHO.
- Who Pays for the VTHO?
VTHO costs are borne by professional data contributors, not by consumers.
Actor
Reason
Garages
Proof of service & trust certification
Insurers
Verified claims & risk reduction
OEMs
Lifecycle traceability
Fleets / Marketplaces
Transparency & resale value
This aligns cost with economic benefit.
- Why This Model Is Sustainable
The automotive lifecycle naturally generates:
recurring events,
predictable frequency,
long-term activity (vehicles last 10–20 years).
This results in:
stable, non-speculative VTHO consumption,
network usage independent of market cycles,
infrastructure-grade demand rather than retail activity.
- Cost Predictability for Partners
Because:
VTHO costs per transaction are low,
usage frequency is known in advance,
partners can:
estimate annual operating costs,
pre-purchase or generate VTHO,
treat blockchain usage as a fixed operational expense.
This is critical for enterprise adoption.
- Why VTHO Is Essential to the Model
Without VTHO:
there is no economic cost to writing data,
no spam resistance,
no usage-based allocation of network resources.
VTHO ensures that:
only meaningful, certified events are written,
the network remains efficient and scalable,
usage reflects real-world activity.
- Key Message for Stakeholders
UDVP transforms real-world vehicle events into structured, auditable blockchain interactions, each backed by a measurable and predictable VTHO cost.
This directly links:
real-world utility
to on-chain activity
without exposing end users to crypto complexity.
- One-Sentence Summary
In UDVP, VTHO is consumed each time a certified vehicle lifecycle event is recorded, creating continuous, predictable network usage driven by real-world activity.
