STK tokens - Cryptocurrency For Instant Global Payments on Ethereum Blockchain




  • On November 13, 2017 STK (“STK Global Payments”) will conduct a Token Generation Event (TGE) and will
    make the STK token available for purchase on the STK token sale site (www.stktoken.com). The STK token
    will enable real time point of sale (POS) transactions directly from users’ private cryptocurrency wallets.
    We predict the ability to make purchases in-store and online using cryptocurrencies will speed up mass
    adoption of the technology. The STK token is part of a global solution to facilitate borderless transactions.
    To make instant payments at point of sale from a blockchain wallet requires we do a real-time exchange
    of cryptocurrency into fiat. The STK token provides access to our state channels which a) ensure there
    is sufficient cryptocurrency (i.e. Bitcoin, Ether) in the digital wallet and b) users spending fiat at point of
    sale will complete the purchase from their cryptocurrency assets. STK automatically opens a state channel
    between each user and STK’s own wallet. STK tokens fund the transaction, much like gas funds Ethereum
    transactions. The first implementation will be with STACK’s digital wallet. STK tokens will be implemented
    on the public Ethereum blockchain and adhere to the ERC20 protocol.


    VISION

    STK Global Payment’s vision is to create a globally accessible alternative to traditional banking, allowing
    you to store your money safely, access it instantly and transact with it anywhere, in any currency including
    crypto by using the STK token, right from your smartphone, using the STACK app. Creating a digital wallet
    as a companion to a traditional card solution, the STACK app enables you to use any of your currencies at
    point of sale, anywhere in the world.

    CURRENT LIMITATIONS OF BLOCKCHAIN SETTLEMENT

    Because very few merchants accept cryptocurrencies at point of sale or online, consumers must exchange
    cryptocurrencies into their local currency to make everyday purchases. Through any existing exchanges this
    can be time consuming, and comes with sizeable fees. Though some companies have made products that
    enable retailers to accept Bitcoin payments, they are currently available at only a tiny number of locations.
    Our goal is for this exchange to occur in real time, anywhere credit cards are accepted, and with fees
    comparable to transaction costs on Ethereum. At present, the confirmation time for Bitcoin transactions
    averages 10 minutes2, far too long for point of sale purchases. Ethereum transactions are faster, at an
    average time of 24 seconds, but even this is too slow for point of sale.3 Furthermore, neither the merchant
    nor the local currency provider are willing to wait the required amount of time for the transaction to be
    confirmed on the blockchain, which is critical to protecting both parties against fraud.

    STK SOLUTION: STK STATE CHANNEL AND STK TOKEN

    There is a two-pronged problem that the STK solution will solve:
    1) A lack of merchant acceptance of cryptocurrency.
    STACK has partnered with an existing payment network that will allow the cryptocurrency
    wallet to be used at 39 million merchant locations.4
    2) Payments at point-of-sale must complete in near-instant time.
    Rather than writing each payment transaction to the blockchain, STACK, will create State
    Channels between the customer and STACK. These channels are an established way to provide
    real time transaction guarantees on the blockchain. Once this is done, customers’ transactions
    will be funded through STK’s liquidity pool to make point of sale purchases instantly.
    To use this system, the user is required to hold a STK token which grant access to the STK State Channel and
    will be limited to those who have STK tokens.

    STK IS A SOLUTION THAT CAN BE IMPLEMENTED GLOBALLY,

    WITH THE FIRST IMPLEMENTATION OCCURRING WITH STACK
    In order for users of the STACK wallet to transact in real-time, the STK solution will be integrated into the
    STACK digital multi-currency wallet. This functionality can only be accessed with a STK token. The STK token
    will be used to pay for the operating cost of setting up the State Channel. Because STK tokens can change
    in value, the price per transaction is calculated similarly to how gas prices are on Ethereum.

    STATE CHANNELS

    State Channels are a technique for making off-chain transactions with the same security guarantees as an onchain
    operation. State Channels allow us to conduct blockchain interactions as if they were being conducted
    on-chain, but require only that two or more users exchange information with each other5. Participants in a
    State Channel may exchange a large number of transactions between one another instantaneously, requiring
    an on-chain operation only when the channel is closed. State Channels provide the speed required for
    STACK’s point-of-sale purchase mechanism: at the moment of purchase, the user sends STK tokens to
    STACK in exchange for STACK using their liquidity pool to make a fiat purchase through the global payment
    network. This is a cost effective approach to enabling transactions.


    HOW DOES THIS WORK IN PRACTICE?

    Step-by-step process:

    1. Creating a State Channel:
    The user loads their STK token into the STACK mobile wallet, which authorizes the creation of a State
    Channel with the STK platform. Both the user’s device and STACK keep a local copy of the current state
    of the channel. Creation of a state channel requires an on-chain operation.

    2. Conducting Transactions and State Changes:

    When the user initiates a point of sale transaction using STACK, they receive a visual prompt in the STACK
    wallet showing the value of the transaction, similar to using traditional tap-to-pay mobile applications.
    Behind the scenes, the user authorizes a transaction to send the equivalent cryptocurrency to the STK
    platform.
    Almost immediately, the STK platform receives the signed transaction, counter-signs and stores a copy
    of that new state off-chain. STK then authorizes its local currency account to pay the requested purchase
    through its global payment network rails on behalf of the user. Because the transaction occurs off-chain,
    there is virtually no delay except for a small amount of computation time and network latency.

    3. Keeping Funds Ready:

    So long as the State Channel is open, there are no fees for conducting any number of transactions
    between the user and STK. Moreover, there is no fee for keeping the channel open.

    4. Withdrawing Funds:

    If the user wants to retrieve all or part of their STK token in the channel that has not been sent to STK, they
    can do so by withdrawing their funds. The user signs and publishes a withdrawal request, which requires
    an on-chain operation. It is possible to make partial withdrawals, so the user is always secure in being able
    retrieve his or her ether while still keeping the channel open for future transactions with the STK network.

    5. Closing:

    To close a State Channel, one of the parties signs and publishes a close request to the State Channel. This
    initiates a period during which either party can submit their most recent transactions, which determines
    the final state of the state channel.
