STK Project Whitepaper Title: Hot Potato: A Global Solution for Instant Cryptocurrency Payments

What is Hot Potato

Friends, imagine you’re holding digital currencies like Bitcoin or Ethereum, and you want to buy a cup of coffee at a café or pay at a supermarket checkout, but the cashier tells you: “Sorry, we only accept cash or bank cards.” Isn’t that a bit disappointing? The “Hot Potato” project, more precisely known as STK Coin (STK), acts as a bridge, aiming to let you use your digital currencies just like a bank card for instant payments in real-world stores.

Simply put, STK Coin is a cryptocurrency project whose core goal is to enable everyone to spend the crypto in their digital wallets directly at any place that accepts card payments. It’s not trying to replace existing payment systems, but rather to integrate cryptocurrency into our daily spending scenarios, making digital assets more practical.

Target Users and Core Scenarios

STK’s target users are those who hold cryptocurrency and want to use it conveniently and quickly for everyday payments. Core scenarios include:

• Daily spending: Shopping at physical or online stores, just like swiping a bank card.
• Instant payments: Solving the problem of long confirmation times for crypto transactions, enabling near real-time payment experiences.

Typical Usage Flow

This process can be understood as follows: you deposit STK tokens into a digital wallet called “STACK” (think of it as a special banking app). When you need to pay, this wallet establishes a “state channel” between you and the STK platform. State Channel: You can think of it as a temporary, private “fast lane” that allows two parties to conduct countless transactions without recording each one on the blockchain “public ledger”—only the final result is put on-chain, greatly improving transaction speed and efficiency.

When you pay with STK, the app automatically converts the product price into the crypto in your wallet, and you authorize the transfer of that crypto to the STK platform. After receiving your authorization, the STK platform uses existing payment networks (such as card networks) to pay fiat currency (the money we use daily, like RMB, USD, etc.) to the merchant on your behalf. The whole process is very fast, and you hardly notice the conversion in between.

Project Vision and Value Proposition

STK Coin’s vision is ambitious: it hopes to create a globally universal payment method that can replace traditional banking systems. Just as we can pay with our phones now, STK wants everyone to securely store funds, access them anytime and anywhere, and transact in any currency (including crypto) via the STACK app on their smartphones.

Core Problems to Solve

Although cryptocurrency is becoming more popular, its use in daily spending is still very limited. The main pain points include:

• Inconvenient payments: Most merchants do not accept crypto payments.
• Slow transactions: Traditional blockchain transaction confirmations are slow, unsuitable for instant payment scenarios.
• Cumbersome conversion: Users need to convert crypto to fiat before spending, which is time-consuming and incurs fees.

Differences from Similar Projects

STK Coin’s uniqueness lies in its combination of Ethereum smart contracts, state channels, and liquidity pools, and its cooperation with existing payment networks like Mastercard. Smart Contract: Think of it as a self-executing digital contract—once preset conditions are met, the program runs automatically, with no third-party intervention. Liquidity Pool: Imagine a huge pool of funds containing various assets, allowing users to quickly swap and ensuring smooth transactions. This combination greatly lowers the threshold for crypto payments, enables real-time payments globally, and provides users with a seamless experience connecting traditional banking services.

Technical Features

The technical core of the STK Coin project is how to make crypto payments as fast as card swipes.

Technical Architecture

STK token is an ERC20 standard token (ERC20 Token) based on the Ethereum blockchain. ERC20 standard token (ERC20 Token): Think of it as a “universal currency template” on Ethereum—any token that fits this template can be used in the Ethereum ecosystem, such as stored in ERC20-compatible wallets or traded on compatible exchanges. This means it’s compatible with the Ethereum ecosystem and can be stored in any wallet supporting ERC20 tokens. The STK platform integrates with the STACK digital wallet and uses state channel technology to enable real-time conversion and payment between crypto and fiat.

Consensus Mechanism

Since STK tokens run on the Ethereum blockchain, they inherit Ethereum’s consensus mechanism. At the launch of the STK project, Ethereum mainly used Proof of Work (PoW), but has now switched to Proof of Stake (PoS). Proof of Work (PoW): Think of it as a “solving math problems” process—miners compete to solve calculations, and whoever solves it first gets the reward and records the new block. Proof of Stake (PoS): Think of it as a “collateral system”—those who hold more tokens and are willing to stake them are more likely to be chosen to validate transactions and create new blocks, thus earning rewards.

Tokenomics

STK tokens are the “fuel” and “pass” of the entire payment system.

Basic Token Information

• Token symbol: STK
• Issuing chain: Ethereum (ERC20)
• Total supply: 500,000,000 STK
• Current circulating supply: About 343,971,371.9709 STK (historical data, please refer to the latest figures)

Token Utility

STK tokens play several key roles in the ecosystem:

• State channel access: STK tokens are the “key” to access STK state channels. Users must hold STK tokens to open and use state channels for instant payments.
• Transaction fee payment: STK tokens are used to pay for the operating costs of state channels, similar to “Gas fees” on Ethereum. Gas Fee: Think of it as the “fuel fee” for operations on the blockchain (such as transfers, executing smart contracts), used to reward miners or validators who process these operations.
• Incentive mechanism: The whitepaper mentions that proceeds from STK token sales will be used for marketing, solution development, and bounty programs to promote ecosystem growth.

Token Distribution and Unlocking Information

STK held its Token Generation Event (TGE) on October 25, 2017. Proceeds from the sale were mainly used for project marketing, technical development, and ecosystem incentives.
