With the development of information technology, in the current digital age, after the blockchain technology has gradually matured and been widely used, the categories and conceptual scope of digital assets can be further expanded. Some digital assets are even regarded as driving the global industrial revolution. catalyst.

What is the trend of digital asset exchanges in the future? It is safer, more transparent, more transactional, and able to withstand greater risks... These may not be the final answer. Digital assets are non-monetary assets that exist in the form of electronic data and are expected to bring economic benefits or potential economic value to asset holders. Whether it is the popularity of decentralization or the competition of centralized trading platforms, always insisting on protecting the core rights and interests of investors is the foundation of the long-term development of a trading platform, and this is the foundation of CRex.

1.CRex, a giant of China Stock Exchange, China Resources Assets has invested heavily in building a global digital ecosystem.

CRex, China Stock Exchange, is a wholly-owned subsidiary controlled by China Resources Assets 100%.

CRex China Exchange is registered in the global financial center-London, UK. It is mainly based on the fact that the UK, like Switzerland, Canada, Australia, New Zealand and other countries, has launched its own digital identity system and has the infrastructure for the trending digital era.

The founding team of CRex of the China Stock Exchange stated that a decentralized exchange is by no means a simple “decentralized” platform, but a completely “on-chain” asset system that carries more than just digital assets. The launch of many Dapps will eventually form a completely “online” asset transfer and transaction ecology, that is, an “on-chain” system that can create all business forms.

2.CRex of China Stock Exchange is committed to an autonomous, safe and compliant blockchain digital asset trading platform.

CRex of China Stock Exchange is committed to creating an autonomous, safe and compliant blockchain digital asset trading platform, allowing institutional investors and individual investors to safely conduct transactions of any size and frequency without worrying about the fairness and fairness of the trading platform. Security, privacy of user data, stability and reliability of the transaction system.

Based on the strong capital power of China Resources Assets and the large number of users, CRex of the China Exchange has always been based on the principle of user interests first, and is committed to developing a new ecosystem of fully autonomous blockchain digital assets symbiosis and co-prosperity.

（1）、Main common problems:

① Security issue: the most prominent issue. ②The transaction process is not transparent: exchanges can use information asymmetry to manipulate prices. ③ KYC information: KYC means Know your customer. When tracing hackers and criminals, the information reserved by KYC can provide very good help, but a large number of traders are doing legal transactions, and the centralized trading platform collects them through KYC. Customer information is also inconsistent with the anonymity of digital currency.

（2）Solve industry pain points, strategic advantages:

In order to change the pain point and realize its original intention, CRex of China Exchange had the following advantages at the beginning of the project design:

①High safety and low cost. CRex of the China Stock Exchange writes custody and clearing into smart contracts and assets on the chain; funds can only flow in and out of the same account; it has passed the most stringent slow fog audit and continuous offensive and defensive tests. CRex on the China Stock Exchange reduces gas costs through smart contracts combined with threshold signature technology, and the batch-on-chain model also minimizes gas costs. At the same time, no costs will be incurred for pending and canceling orders, which is also a big advantage.

②High performance, deep integration of transactions. CRex of the China Exchange has adopted the "off-chain matching, on-chain settlement" model to achieve rapid transaction completion. CRex of China Exchange will use the mechanism of order pool sharing in the early stage to promote the in-depth development of transactions. By providing technical support to the wallet party, every wallet connected to CRex of China Exchange can share the order pool of CRex of China Exchange and gather all major players. The transaction volume of the wallet increases the transaction depth of the trading platform.

In the later period, CRex of the China Stock Exchange directly shared the trading depth with mainstream exchanges, mainstream currencies such as BTC, etc., to ensure transaction liquidity.

③High-speed matching engine, trusted atom cross-chain. CRex of the China Exchange has optimized the Loopring protocol, which has enlarged the advantages of on-chain matching and off-chain settlement. Currently, it supports matching transactions between BTC and other assets. The original trading system supports more than a dozen legal currency pair transactions worldwide. Since there is no management by a central organization, decentralized exchanges require powerful cross-chain technology. CRex of the China Exchange has adopted trusted atomic cross-chain technologies to ensure that transactions between assets on different public chain platforms can proceed smoothly.

④APP access is easy to use, CA symbiosis agreement, co-prosperity ecological layout. CRex of China Stock Exchange has launched full-platform client support, supporting APP, H5, PC terminals, and supporting market and trading APIs. The core members of CRex of the China Exchange are well versed in the principle of symbiosis and co-prosperity. Therefore, a sound ecological layout was built at the beginning of the project. On the one hand, it can break down the barriers between industries and increase the circulation and use of CRA. Provide users with more investment and income channels.

⑤Double deflation model, increasing value. The CRex ecological token CRA of the China Exchange adopts a dual deflation model, namely platform deflation and project deflation. For the platform, account activation, project voting, ecological applications, balanced issuance of mining pools, and node applications will consume a certain amount of CRA.

⑥It is highly suitable for the underlying design of DeFi. CRex of China Exchange is highly suitable for DeFi projects in the core component order book, matching system, settlement contract, that is, the design of the corresponding front-end, back-end, and contract layer, which can bring better liquidity and transaction experience to users, thus bringing To bring greater benefits.

3. CRex of China Stock Exchange adopts CA+DeFi+NFT mechanism, technological innovation, decentralized business credible ecology.

CRex of the China Stock Exchange takes the CA co-existence agreement as the basic consensus, adopts the CA+DeFi+NFT mechanism, and uses dual deflation, dual ecology, and five symbiotic mining pools as the main implementation strategies to create a decentralized transaction of symbiosis and prosperity from the technical field platform. The performance is as follows:

① Safety guarantee-three-dimensional protection

CRex of the China Stock Exchange cooperates with world-class security companies to conduct code audits on the entire site code before going online. Set up a multi-level firewall to monitor system data abnormalities in real time. In terms of user assets, a wallet solution with multiple signatures and hot and cold isolation is adopted to ensure the security of user assets to the greatest extent.

② Loopring protocol-on-chain settlement, off-chain matching

The Loopring protocol adopted by CRex of China Stock Exchange is an open source decentralized transaction protocol. Order generation, dissemination, and matching are off-chain, and clearing and settlement are on-chain to solve the problem of on-chain transaction congestion and ensure open and transparent capital flow. There is no need to recharge, withdraw cash, and cannot touch user funds.

③Atomic swap agreement-trusted cross-chain asset transaction

Cross-chain is one of the many problems faced by blockchain, which restricts the development of blockchain applications. Decentralized exchanges and cross-chain technology have a natural strong combination. In order to realize the circulation and trading of multi-chain assets, CRex of China Exchange adopted the credible HTLC atomic swap protocol.

④Asset management contracts-to prevent damage by external forces

When preventing damage from external forces, CRex of China Exchange also built a corresponding security system internally. Such as the introduction of asset management contracts, it supports the establishment of centralized asset management contracts on the chain, restricts funds entering the exchange, and defines control addresses with different permissions to control assets.

⑤Embedded Kubernetes open source platform-high load performance

CRex of China Stock Exchange will build a decentralized business ecosystem including thousands of enterprises in the future, so it has high requirements for load. In order to meet this requirement, CRex of China Stock Exchange chose to embed the Kubernetes open source platform.

Kubernetes is an open source platform that can automatically implement Linux container operations. It can help users save many manual deployment and expansion operations in the application containerization process.

⑥ Threshold signature technology-reducing data and computing costs

Threshold signature is a distributed multi-party signature protocol, including distributed key generation, signature and signature verification algorithms. In recent years, with the rapid development of blockchain technology, signature algorithms have received extensive attention in academic research and commercial applications, especially in the dimensions of security, ease of use, scalability, and distributability.
