Most exchanges are in the mode of currency matching or over-the-counter trading. According to the current understanding of market trading gameplay, users are not limited to a single gameplay, but prefer diversified operations. At present, the mode of exchange in the market: (1) Introduction of trading mode of price limit: Price limit buying/selling means that the user sets the price and quantity of a buying/selling currency, generates a consignment note, and the system will automatically match the buying and selling orders in the market. Once the price set by the user is reached, the transaction will be completed automatically in the order of price priority. (2) Introduction of market trading mode: Market buying means that users set a total amount, generate an order, and match it from the beginning of selling to the completion of the total amount. Market selling means that the user sets the total amount to be sold, generates an entrustment document, and matches it from the beginning of buying to the completion of the total amount transaction. (3) Introducing currency trading mode: Currency trading is mainly aimed at the transactions between virtual digital assets and virtual digital assets, and one of them is used as the pricing unit to buy other currencies. When necessary, the exchange can inquire about the currency trading rules, and the matching transaction is also completed in the order of price priority. (4) Introduction of C2C trading mode: Both parties to the transaction publish trading information of buying or selling coins on C2C trading platform according to their needs. The buyer and the seller complete the transaction offline according to the agreed payment method, and the platform acts as an intermediary to collect a certain percentage of the handling fee from each successful transaction. (5) Introduction of OTC trading mode: It is a platform for offline purchase in digital currency, independent of the exchange. Merchants can post purchase and sale advertisements on this platform, and purchase and sale users can purchase and sell through offline transfer. After the transfer is completed, the platform will transfer the frozen digital currency to the buyer. The technical construction of the exchange can be found by Baidu search consulting. (6) Introduction of mining mode: The exchange platform will return a certain percentage of commission income to the platform users, and the platform currency will be returned. According to the principle of proportion, the exchange platform will give a certain proportion as a mining reward. Mining refers to trading on the platform to gradually unlock the platform coins until all the platform coins are fed back. This kind of gameplay is very attractive to attract users. (7) Introduction of futures/contract trading mode: A futures contract is an agreement that the buyer agrees to receive assets at a specific price after a specified time, and the seller agrees to deliver assets at a specific price after a specified time. The price that both parties agree to use in future transactions is called futures price. The designated R period in which both parties must conduct transactions in the future is called the settlement date or delivery date. The assets that both parties agree to exchange are called "targets". (8) Introduction of perpetual contract trading mode: perpetual contract is a new and unique contract, and its goal is to replicate the market situation of spot market with high leverage.

The contract evolved from the traditional futures contract, but the perpetual contract has more obvious advantages and greater risks than the traditional futures contract, supports long and short two-way trading, provides leverage of 100 times, can hold positions permanently and can pay a premium.
Blockchain cross-border payment system development, digital currency stock exchange system development blockchain+cross-border payment new gameplay. Simply put, blockchain is a chained data structure, which combines data blocks in an orderly manner in time sequence and cryptographically ensures that it cannot be tampered with or forged. The development of the original Sino-Swiss blockchain payment system added the cross-border payment of blockchain gameplay, and the whole system was built on the P2P (peer-to-peer) architecture of blockchain, achieving a high degree of disintermediation. Each node in the system enjoys account books, and no longer relies on traditional intermediaries such as banks and remittance companies to complete accounting services. Instead, it directly completes the conversion between different legal tender currencies in the blockchain network, and the transaction is confirmed and cleared by the * * * identification algorithm. At the same time, because all transaction information is recorded in the distributed ledger, the blockchain+cross-border payment model has the properties of high data security and high system reliability, which makes it difficult to forge and tamper with transaction data and will not affect the operation of the whole system because of a node failure. It is worth mentioning that any financial institution can use its own network to deploy and pay for the system quickly and conveniently, and it is not necessary to implement a comprehensive hardware update in order to join the system, which saves a lot of construction costs and communication costs for the large-scale deployment of new channels. What are the advantages of blockchain+cross-border payment? 1. Point-to-point mode reduces cross-border payment costs. In the blockchain peer-to-peer model, it no longer relies on traditional intermediaries to provide credit certification and accounting services. Any financial institution can use its own network access system to realize point-to-point payment information transmission between the receiver and the payer. 2.*** Enjoy the ledger and improve the efficiency of cross-border payment. All nodes in the blockchain * * * share account books, and peer-to-peer transactions between nodes use the * * * identification algorithm to confirm transactions, and broadcast the results to all nodes, so it is no longer necessary for both parties to establish hierarchical account agency relationships to realize peer-to-peer value transfer. 3. Distributed architecture provides business continuity guarantee. There is no central node in the distributed system architecture of blockchain network, and each node on the network conducts transactions and bookkeeping spontaneously on the basis of following the necessary protocols, which has stronger stability, reliability and business continuity guarantee. 4. Time stamp realizes the traceability of cross-border transactions. Time stamp can ensure that all transaction activities can be tracked and queried, and reduce the regulatory cost of cross-border payment transactions. 5. The automatic execution of intelligent contracts improves the transaction efficiency. The handling of cross-border payment business needs to review the identity of customers according to KYC policy, and limit the conditions of value transfer through blockchain smart contracts to improve the automation of transactions.
