Devery (EVE Token) : An open-source protocol for veri cation services on the Ethereum network.

  • Devery Protocol and Ecosystem

    The underlying Devery Protocol will enable developers to easily create veri cation
    applications without a thorough understanding of the blockchain. The Devery Protocol
    will abstract the complexities of interacting with smart contracts by deploying
    pre-developed smart contracts for an improved developer experience. The end result is
    an ecosystem of veri cation applications that communicate and interact with each other
    through the Devery Protocol.

    Decentralized protocol layer

    The protocol layer consists of 3 main data structures that interact via the Ethereum
    mapping method within the DeveryRegistry.sol and the DeveryTrust.sol contracts.

    The application layer speci es an address to register the application's unique
    identi er on the protocol alongside the application's name and fee account.
    This allows the application to collect fees from users of third party
    veri cation applications built on the protocol.

    struct App {
    address appAccount;
    string appName;
    address feeAccount;
    bool active;

    Brands input their public key address to specify their corresponding brand
    name, and this is stored alongside the appAccount which will thereby be used
    to store the brand information and the products veri ed.
    struct Brand {
    address brandAccount;
    address appAccount;
    string brandName;
    bool active;

    Products store the associated brand account as well as product information.
    struct Product {
    address productAccount;
    address brandAccount;
    string description;
    string details;
    uint year;
    string origin;
    bool active;

    This information is then hashed via the addressHash(address item)
    function and marked with the corresponding product public address, which
    uses the hashed address as a reference for lookup. This is the individual
    identi er for each product stored on the blockchain, and allows lookup via
    the check(address item) method.
    The Devery trust contract

    Devery.js provides a npm packaged Javascript framework that is built on top
    of Web3.js and the protocol layer to create an abstracted, developer-friendly
    tool to build on the Devery protocol. Using this layer, developers can opt to
    interact with the blockchain through Javascript and build commercial
    veri cation applications without the need to interact directly with the
    protocol's smart contracts.

    We have also provided a simple key generation tool to allow developers to
    generate public key addresses and associated QR codes for input into their

    Decentralized application layer

    Applications will build on top of the protocol to form the decentralized application layer.
    This will enable commercial applications to build and charge for services whilst using the
    Devery protocol.
    For Example, Bevery may choose to use the Devery protocol to verify
    individual beverages on the blockchain. Using the Devery protocol,
    developers will interact via the Devery.js framework or choose to directly
    develop via the smart contracts deployed on the blockchain.

    Entry Veri cation Engine (EVE)

    EVE is used to fuel the veri cation process. Applications will recieve EVE token as
    payment for hosting veri cation applications on the Devery protocol. Consumers using
    these applications will require EVE to mark on the blockchain, this EVE is then
    transferred to the application host as payment for hosting the applications via the
    'Bokky's Token Teleportation Service' (BTTS), allows users to send EVE tokens without
    required Ethereum as a gas cost. Users can send message to third-party services to
    process their transactions and pay the gas cost on their behalf. In return, the user pays
    the service provider a percentage of EVE tokens. This provides a practical means of
    using the Devery protocol without requiring retailers and others users to hold EVE and

    Prototype & How it Works

    Devery provides the toolset to allow companies to build commercial
    verification applications on top of our protocol, fueled by our native
    EVE token.
    We have released our alpha protocol on testnet. You can
    view this via our Github. At the conclusion of the crowdsale, EVE will
    be usable within the protocol.



    Use Cases

    This paper will describe a few example use cases of the Devery Protocol. This is not an
    exhaustive list.

    Online Product Veri cation

    The Devery Protocol enables e-commerce retailers to verify the authenticity of any
    products or services they sell online. Retailers can assign unique ID signatures to each
    product sold online with a third-party veri cation application built on top of the
    Protocol. The retailer can then display unique one-time-use hashes generated from this
    ID to any potential customers that wish to verify the authenticity of a product.
    Consumers then log onto the application and input the code marked on the product in
    order to identify its authenticity. As well as this, origins and manufacturing can be
    disclosed dependent on the brand's preference.
    An example of what this may look like is illustrated in the diagram below:

    Digital Signing

    The Devery Protocol can be used to verify that digital goods and services are issued
    from a legitimate source. An example would be digital certi cates from online courses,
    colleges or universities. A certi cate can be assigned a unique ID signature that can be
    veri ed via an application built on top of the Devery Protocol. The recipient of the
    certi cate and any potential employer that wants to check its legitimacy can verify the
    certi cate through this application. Further, details regarding the recipient?s results,
    behavior or other academic details can be stored on the chain.

    •  Physical Signing

    NFC and RFID chips, as well as barcodes and QR codes are compatible with the Devery
    Protocol. Unique ID signatures generated from the protocol can be stored into a physical
    marker and attached to a product. As the product moves across the supply chain, each
    party that handles the product can verify its source via an application on the Devery
    Protocol and update details (such as the location through which the product moves,
    timing and other conditions). The consumer can scan the hardware device to verify the
    movement of the product along the supply chain.
