QT Coin Exchange is the world’s leading digital asset trading platform. The core team members come from well-known technology companies and financial companies. They are deeply involved in the blockchain technology community and traditional financial industry. The platform has many years of experience in digital asset financial services, professional distributed architecture and DDOS prevention. Attack the system and create a blockchain ecosystem with multiple business forms through the establishment of an advance payment mechanism, the establishment of investor protection funds, and the establishment of localized transaction service centers in multiple countries.
At present, QT Coin Exchange has successfully created a one-stop trading service for digital assets, which can simultaneously provide users with trading services including currency trading, contract trading, option trading, liquidity mining, wealth management, subscription, etc., covering iOS and Android, Windows multiple platforms, support full business functions.
The exchange business
QT Coin Exchange is constantly expanding in digital currency basic trading services, token derivatives, liquidity mining, and financial management.
1) Basic trading services
• Coin Trading: QT Coin Exchange uses API to interface with the entire network of currency transactions, providing investors with sufficient digital asset transactions. Currency trading is divided into three major sections: mainstream currency area, potential currency area, and Shanghai new currency area. The transaction price can adopt market price transaction and limit price transaction, and users can conduct transactions according to their own needs. At the same time, to prevent users from placing orders incorrectly and causing abnormal market price fluctuations and personal financial losses, QT Coin Exchange will provide an instant reminder service.
• Contract Trading Area: The original intention of the QT Coin Exchange standardized contract design is to hedge against spot risks. To lock in the cost of income and hedge against the risk of sharp fluctuations in spot prices, companies or individuals engaged in the trading of large digital currencies will place short orders (long Single), used to resist risks. We adopt spread delivery. When the contract expires, the system will settle all unclosed positions at the delivery price. At the same time, QT Coin Exchange will provide a perpetual contract that can replicate the situation in the spot market with high leverage. The contract will not be delivered, and can closely follow the reference price index through various mechanisms. The most important mechanism is the price index funding cost, which is to calculate the funding rate based on the price index.
2) Token derivatives trading service
QT Coin Exchange will provide token derivatives transactions including token forwards, token swaps, token futures, and perpetual contracts.
QT Coin Exchange Core Advantages
QT Coin Exchange takes digital asset transactions as the entry point. Through data testing and analysis of a large number of business models and application models, QT Coin Exchange can achieve second-level transaction verification, massive data storage, high throughput, and fast node data synchronization in terms of performance. In terms of scalability It can meet the requirements of multi-service block structure and permission control strategy. At the same time, it provides secure private key access services and privacy protection schemes.
1) Fast transaction verification
By optimizing key links such as signature algorithm, ledger structure, data operation, serialization, consensus mechanism, and message diffusion, QT Coin Exchange can achieve rapid transaction verification in seconds. Meet the user experience of most blockchain application scenarios.
2) High throughput
The essence of blockchain is a distributed shared accounting technology, and its distributed characteristics are mainly reflected in distributed consistency rather than distributed concurrent processing. In order to ensure data consistency and prevent the Byzantine Generals problem, certain specific links can only be executed serially, not parallel. Through long-term testing and optimization practices, the processing performance of QT Coin Exchange has been able to meet the needs of ten thousand TPS. If mechanisms such as Off-Chain are introduced, transaction throughput can be further increased significantly.
3) Secure private key access
In order to facilitate users to use blockchain products and services, in addition to the traditional client-side generation and storage mechanism, QT Coin Exchange also provides two solutions: network hosting access and private key hardware access (U-key). Web hosting access, that is, the user name and password are mapped into a private key through a specific algorithm and stored on the server. The private keys stored on the server side are all encrypted data, and the private keys can only be decrypted on the user side; the hardware private keys are used to meet the needs of the financial industry and the Internet of Things industry.
4) Multiple privacy protection schemes
Provide multiple privacy protection functions. First of all, the bottom layer of the blockchain provides a homomorphic encryption method, all user data is encrypted and stored, and only the user himself can see it. Secondly, QT Coin Exchange Adaptors provides encryption middleware services, and users can choose according to their business needs. Finally, the upper-level application can encrypt data when entering it, and QT Coin Exchange is responsible for writing and reading encrypted data generated by users.
5) Low-cost access method
 QT Coin Exchange Adaptors abstracts API interfaces suitable for multiple business scenarios for direct use by scenario-based businesses. Under new business scenarios, QT Coin Exchange can quickly customize the interface for users based on the existing framework to meet business functional requirements.
At the same time, QT Coin Exchange provides packaged SDK software development kits that support multiple mainstream development languages ​​(JAVA, C++, node-js, PHP). Blockchain is an emerging technology. Only by continuously meeting business needs can it become mature. Therefore, we lower the threshold for upper-layer applications by encapsulating the underlying distributed ledger, and continuously optimize during the process of docking and use. And improve the underlying distributed ledger and consensus algorithm to make it closer to commercial demands.
6) Liquid mining area
DiemWor provides liquid mining services. The liquid mining mechanism encourages users to inject funds into the decentralized ecosystem or provide other value-added services. In return, the platform will issue rewards to them. The miners of liquid mining will obtain the platform’s native governance certificate in proportion to increase its annualized investment yield. Liquidity mining rewards are not included in the income of the platform itself, but an additional income. QT Coin Exchange liquidity mining has two main purposes:
The first is to encourage users to inject liquidity into DeFi applications to increase the total lock-up volume (TVL) and capital supply of the application. Increased liquidity can effectively reduce transaction slippage and enhance the competitiveness of applications, thereby attracting more users to join.
The second is to fairly distribute the governance tokens of DeFi applications to users. These users deposit funds on the platform and bear the corresponding opportunity costs (such as impermanent losses). Since the tokens are distributed fairly, neither party will be favored, so that a decentralized governance model can be truly realized.
QT Coin Exchange game ecology
QT Coin Exchange builds a game ecosystem based on mature trading business, and on this basis, launches games such as parachuting, 1U coin grabbing, and height guessing.
