    Vanig Solution

    An e-commerce platform built entirely around the blockchain. Our platform uses Hyperledger Sawtooth to build an e-commerce ecosystem that tackles key issues in e-commerce today.

    Problem

    Fractured Tracking

    Tracking the source of all the materials used to make a product along with the product is insanely difficult, since it is fractured and split across multiple shipping services.

    Solution

    Total Tracking

    All the transportation records are stored in the blockchain forever, allowing you to track your orders more efficiently, from manufacturing to delivery.

    Problem

    Long Payment Waiting Periods

    If you buy a product from a seller today, the seller has to wait for a long while in order to get the payment for the product. On top of it, the seller loses money in the form of fees.

    Solution

    Instant Payment Transfers

    On the Vanig platform, your payment is transferred to the seller immediately in the form of VANIG tokens. This enables the seller to ship your items faster and also results in fair margins for both Vanig and the Seller.

    Problem

    Dealing with Middlemen

    Long supply chains result in an increase in the number of hands a product changes, resulting in an increase in the final price of the product.

    Solution

    Reducing/Eliminating Middlemen

    Vanig can effectively reduce the number of middlemen, resulting in the product becoming cheaper for you, and lucrative for the seller.

    Problem

    Lack Of Information On Raw Materials

    Right now, the information about raw materials used in the manufacture of a product is hidden in data silos that are hard to open without formal investigation or other long tedious means.

    Solution

    Complete Transparency

    The Vanig platform can store detailed vital information about the raw materials used in the manufacturing of a product, enabling complete transparency about how the product has been made.

    Introducing the Vanig Marketplace

    A blockchain-powered marketplace which connects buyers and sellers directly, cutting out the middleman in the process. Fast, efficient and reliable.

    • Purchase using VANIG tokens, cryptocurrencies or Fiat!
    • Products handpicked by experts & AI Algorithms.
    • Prices that are hard to resist.
    • Information about where products come from.
    • Verified Sellers and Reviews.

    Frequently asked questions

    What is Vanig?

    Vanig is an integrated E-commerce platform and Supply Chain ecosystem that is powered by the blockchain. We aim to solve some of the major inefficiencies and challenges with the existing Supply Chain and E-commerce platforms.

    What are the problems and challenges that Vanig addresses?

    Vanig is aiming to solve the following major problems in the Supply Chain and E-commerce space.

    • Lack of transparency and full visibility in the Supply Chain
    • Too many intermediaries and manual paper work
    • Static or non-existent inventory management
    • Inefficient tracking of products
    • High selling fees on E-commerce platforms for sellers
    • Lack of provenance information for products for buyers

    For a detailed list of all problems that Vanig addresses please check our whitepaper

    What is the Vanig E-commerce Platform?

    Vanig is building an E-commerce platform from the ground up. The Vanig E-commerce platform will be beneficial to all participants. The sellers will enjoy benefit of lesser selling fees (compared to other major E-commerce players) and instant payments, and the buyers will enjoy the benefits of buying trusted products, paying with different payment methods (including VANIG tokens) and be rewarded for purchases on the platform.

    What are the major differences between Vanig and other E-commerce players?

    Here are the key benefits of Vanig over other players.

    What blockchain technology does Vanig use?

    Vanig is built on Hyperledger Sawtooth. Hyperledger Sawtooth has some unique advantages that lends itself for Vanig’s Supply Chain solution. Some of them are –

    • Private networks with the Sawtooth permissioning features
    • On-chain governance – Utilize smart contracts to vote on blockchain configuration settings such as the allowed participants and smart contracts
    • Advanced transaction execution engine – Process transactions in parallel to accelerate block creation and validation. This will help scalability when we have large volume of transactions processed in the Vanig E-commerce platform.
    • Support for Ethereum – Run solidity smart contracts and integrate with Ethereum.

    For more information refer our Whitepaper.

    Vanig is a member of the Enterprise Ethereum Alliance.

    Do you have a working demo or MVP?

    Vanig’s E-commerce platform will be modern and sleek, it will have easy navigation for the buyers and sellers. We have an early demo of the E-commerce platform that will be made available for everyone to try out in May 2018. Please check back for a link to the demo platform.

    Where can I find information on Vanig’s roadmap?

    Vanig’s journey started in early 2017, we have since then come a long way from assembling best in class team and advisors to building the solution framework and MVP.

    We are launching the Token sale in June 2018, our e-commerce platform's alpha version in September 2018 and launch the platform for South East Asia in March 2019.

    We are excited to be on this exciting journey to build Vanig as we envision it. Please check our whitepaper for a detailed roadmap.
