vehicle lifecycle management

Description

Project Description:

The problems in the current system we have addressed and provide the solution in Blockchain.

As we all know that the current and existing system has centralized database. The drawback of existing Vehicle Management lifecycle system are as follows:

  1. Consumer trust is lacking
  2. Verification by data provider is not available.
  3. No scope for real-time updaters.
  4. Centralized and hence can be changed for commercial purpose.
  5. Subjected to fraud from bank, insurance and leasing companies.
  6. Weeks’ time for Updating of vehicle details to RTO

 

Benefits of Proposed solution: Integration among different organizations (ex. RTO, Insurance, Bank, Manufacturer, Dealer) will really benefit at each organization to improve their sales and services due to excellent transparency and speed process.

  • Operational cost will be reduced 5% on each peer and organization.
  • Transparency is maintained among all systems.
  • Fault tolerance across the systems.
  • Customer trust is built through the proposed system as he can find the information related to his vehicle at one place rather approaching different cross organizations.
  • Resellers can trust the vehicle as the original parts of the vehicle are traceable.

How it works:

Integrating blockchain solves the problem of asymmetrical information in the used vehicle market by creating a Decentralized, immutable, transparent, secure, and reliable vehicle life-cycle repository.

Create a block with different levels of access and information protection. Data security level should correspond to the needs of government agencies.

All the records from data providers is hashed and added into Blockchain.

The data itself is stored in service provider’s databases but its hash in the Blockchain.

 The validity of the information provided can be checked by the hash code.

Create an infrastructure and provide direct access to the database for each market participant.

Roles and Responsibilities

-Network setup for Hyperledger Fabric.

-Understanding of Functional architecture of Vehicle lifecycle management and

 Implemented in technically.

-Developed POC  and Whitepaper.

-Implemented Channel creation, channel join conditions, Governance rule and  

 Endorsement policy design as part of the development.

-API development and UI connectivity.

ICO crowdfunding for the business (End to End)

Company

ICO crowdfunding for the business (End to End)

Description

Project Description:

ICO for crowdfunding was done for the business Helloworld video sharing platform.

It is similar to youtube but with this app by registering itself users can avail 10 tokens. For watching the video and good comments.

User attention is the most valuable resource on the Helloworld video platform, and it is rewarded! Any registered user who has watched a video, will get from 25% to 95% of the funds allocated by advertisers.

Creators who upload their video content on the platform, receive 65% of the funds spent by advertisers, and 90% of the funds received as payment from users who watch their premium content.

Helloworld provides advertisers with accurate statistics for each ad view. All data is

recorded on the blockchain and can be checked by both advertisers and third party

auditors. The payments for user’s attention are made directly, without intermediaries and is completely transparent. Advertising costs are 20% lower than on centralized video platforms.

Advertisers may upload on the platform their advertising video that promotes an event, a website, a product or a service, by indicating in the settings a cost-per-view and by targeting based on audience country, city, gender, age and interests.

The video will only be shown to those users who are in the selected targeting group. A reward, specified by an advertiser in the settings, will be added automatically to users’ wallets for each unique viewing of the video.

Advertisers may add their banner or a short promotional video for up to 30 seconds to appear in the videos that are listed as free to view by their uploaders. It is possible to choose targeting based on audience country, city, gender, age and interests. Both the author of the video where the ad is displayed, and the user who watches the video, will automatically receive a reward specified by the advertiser for each unique ad view. The author receives 65% of a costper-view, and the user receives 25%.

Advertisers may add a video that promotes a specific product or a service, to the marketplace, along with a text description, technical characteristics and price.

Users can buy the product or the service advertised in the video, by clicking the “Buy” button and paying HWVSP tokens directly from their wallets to the wallet of the advertiser.

Video creators can upload their video and specify the price on a per-view basis.

Video creators can create a paid channel, for which users pay a daily, weekly, monthly or yearly subscription fee.

Video creators can upload their video and specify them as free to watch.

Video creators can upload their video and specify that users can watch the video for free, and that the video is adfree.

How it works:

Users can watch free videos without ads with the option to support content creators by donating some HWVSP tokens if they

liked the video.

Users can watch free videos with ads embedded in them and automatically receive in their wallets 25% of the cost-per-view

specified by the advertiser.

Users can watch promotional videos uploaded by advertisers and automatically receive in their wallets 90% of the cost-per-view specified by an advertiser.

Users can watch premium content on a pay-per-view basis, or pay a subscription fee for a daily, weekly, monthly or yearly access.

Users can buy the goods and services, advertised in the videos and pay sellers with HWVSP tokens directly from their wallet.

Blockchain and tokens are necessary to achieve full transparency of payments, anonymity, and for reaching the full decentralization of the video platform, both in terms of video storage, and mutual settlements between users.

All mutual settlements between advertisers, content creators, users, sellers and buyers are carried out by HWVSP tokens: this will directly boost demand for HWVSP tokens.

Roles and Responsibilities

-Designed architecture for ICO for crowdfunding.

-coding was done for ICO with all phases (Airdrop, Early bird offer…etc)

-Developed first web page for raising funds from ICO model and second webpage has been developed for video sharing.

-Preparation of whitepaper.
