Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).

Our solution can be thought of as a tamper-proof digital vehicle passport:

• We will create a token for each intervention that certifies the work carried out.
• Documenting the life cycle of each vehicle, from production to final disposal.
• Providing a tool that will benefit the end users of these comercial operations.
• This information would be public and truthful.
• Thanks to Blockchain Cardano, durable and immutable.

Good actors will benefit, facilitating increased sales for both individual owners and specialized businesses.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

A first phase of private beta testing will be carried out on the preview test network to validate the application concept.

Once the concept has been validated, a web3 application will be published. The public section will allow users to view information about vehicles and their repairs, while the private section, accessible via an access token, will allow users to register new vehicles and new tasks.

Describe realistic measures of success, ideally with on-chain metrics.

We will consider the proof of concept to be valid when the general public can consult the data of a specific vehicle by searching the web.

For the private section, partners must be able to correctly create new vehicles and add new tasks and maintenance.

It will also be possible to renew the access token once it expires.

DOH aims to onboard on Mainet 100 active partners in the first year, and secure 300,000 operations. Increasing the user base for Cardano’s ecosystem

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Problem Perception:

When reviewing the different sectors of our economy and looking for the one that causes the biggest trust issues among the users is, the car trading industry is the first one that comes to mind.

Unfortunately, this industry is plagued with bad actors who falsify information to ensure a sale.

Approach:

Our solution proposes the creation of a standard used globally, in which the agents who carry out the maintenance, service intervals and repair operations are the ones who certify the work done on each vehicle.

This information would be public, truthful and, thanks to Blockchain Cardano, durable and immutable. We will create a token for each intervention that certifies the work carried out. It can be thought of as a tamper-proof digital vehicle passport, documenting the life cycle of each vehicle, from production to final disposal.

With the increased use of our app, good actors will benefit, facilitating increased sales for both individual owners and specialized businesses.

This will make bad actors rethink their sales strategies and change their sales processes to be more truthfull with the information they provide.

Ultimately, it's about providing a tool that will benefit the end users of these comercial operations

Target Audience:

Digital Owner's Handbook is designed to engage:

• Mechanical workshop partners at the first step of the solution. They are responsible for obtaining and certifying information on the work performed.
• Vehicle repair partners responsable obtaining and certifying information on the work performed.
• Other actors in the vehicle life cycle partners related to the automotive industry that at some point in the vehicle's life they intervene in it, certifying the installation or replacement of components.
• Second hand vehicle sellers Interested on the use of truthful and certified information.
• Online sales platforms Interested on the use of truthful and certified information.

Uniqueness of the Solution:

Digital Owner's Handbook aims to unify the information related to each vehicle into a global standard, creating a reliable and lasting record that will benefit good actors.

Importance to Cardano:

The decision to develop DOH on Cardano’s ecosystem by:

• Web3 friendly: We simplify access to our application with trusted Cardano’s credentials.
• Growing Cardano transactions: - As a native application in the Cardano ecosystem, the increased use of DOH will increase the chain's usage. - It will also bring Cardano, directly or indirectly, closer to a large number of users of trading platforms and individuals.

Benefits for the general public:

Promotes the sale of vehicles with DOH:

• As a seller, you will be on a more favorable position compared to the competition.
• As a buyer, you’ll have the confidence that work has been done on the vehicle.
• All things being equal, the buyer will choose the vehicle that offers the most guarantees.

Regulation on End-of-Life Vehicles (ELV)

• An independent motor vehicle expert’s report will soon be mandatory for vehicles sales. With DOH, you can create a certified report
• Car dealers and trading platforms must retain relevant documentation for two years. With DOH, your data is securely stored and immutably.

Manufacturer's Warranty for Warranty Maintenance:

• If a breakdown is covered by the warranty and the manufacturer suspects it was due to a lack of maintenance, they may request proof that the program was followed. If you can't prove this, they may deny your warranty claim.

Legal Liability in Accidents

• If your vehicle is involved in an accident and a mechanical failure that could have been avoided with proper maintenance (e.g., worn brakes, poor tires) is determined to be the cause or a contributing factor, you could be held legally responsible for the resulting damages and injuries. This is based on the principle that drivers have a legal obligation to keep their vehicles in safe roadworthy condition.

Insurance Claims

• Insurance companies thoroughly investigate the causes of accidents. If they discover that poor maintenance played a role, they could deny or reduce your insurance claim.

Personal Injury Claims

• If someone is injured due to a vehicle failure related to a lack of maintenance, that person could file a personal injury lawsuit against you. Proving the connection between the lack of maintenance and the accident can be complex, but an experienced attorney can seek out experts to establish that connection.

Other legal obligations:

• Depending on the location of the vehicle, certain specific regulations may need to be applied, such as the End-of-Life Vehicle Regulation (ELV) in the European Union.
• An independent motor vehicle expert report will soon be required for the sale of a second hand vehicle.
• In addition, dealers and trading platforms must retain related documentation for two years.
• Another example would be the Mandatory Certificate of Destruction for vehicle decommissioning, an effective tool against the illegal transport of end-of-life vehicles. It is expected to come into force in the European Union in 2026.

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

Value to the Cardano Community

DOH solution will bring significant value to the Cardano ecosystem by expanding network adoption and increasing transactions on the network.

By making popular and accessible Web3 technology, we reduce the technical complexity that often discourages users from participating in other related applications.

Measuring Impact:

We will measure the impact of DOH on the Cardano community using both quantitative and qualitative metrics:

• Total Active Partners:
  • We aim to include each of our partners as active users of the chain, ensuring its use with every operation carried out in our APP.
  • Once our partners, who are mostly not connected to the blockchain world, have security and experience using the chain, they will interact with the rest of the ecosystem, such as DeFi platforms, lending platforms, chain explorers, etc.
• User Growth and Engagement:
  • We will closely monitor the partners added to our system.
  • Although the barrier to entry is mandatory KYC, it is essential to ensure the accuracy of the data provided by our partners.
  • The advantages our solution offers to industry players may lead to a greater increase than expected.
• Return Of Investment to the Treasury:
  • At this point, we want to introduce the concept of ROIT, by which we calculate the period over which the requested budget is returned to the Treasury through the "tau" (τ) transaction fee (treasury_growth_rate), currently set at 0.2 (20%) DOH 10-year projection.%5D(https://i.postimg.cc/FHWDk7Vp/DOH-10-year-projection.png).)
  • In the simulations carried out, and using the Internet Adoption Curve model Technology adoption life cycle - Wikipedia%5D(https://en.wikipedia.org/wiki/Technology_adoption_life_cycle)) a 3-year ROIT has been calculated.
• Security Audits and User Feedback:
  • By conducting regular security audits and gathering qualitative feedback from users, we ensure a secure, transparent, and user-focused platform.
• Sharing Outputs and Opportunities:
  • To maximize transparency and engagement, DOH will share its outputs and achievements with the Cardano community through several channels.
  • Partnership Announcements:
    • We will actively promote new partnerships and integrations with Cardano-based projects to the wider community, highlighting how these collaborations.
  • Educational Content:
    • We will produce blogs, tutorials, and AMAs (Ask-Me-Anything) sessions to educate the Partners community on how to work whith DOH.
    • We will use the platform andamio.io (https://app.andamio.io) to certify our partners' knowledge of using the application.
