     The computer device  12  in risk investment end includes a first user interface program  120  for a risk taker  6  to set subscription quantities of risk investment units  1200  and execute through the first user interface program  120  to allow the computer device  12  in risk investment end execute the high leverage risk trading provided by the quasi-decentralized financial investment system  1  based on blockchain. 
     The computer device  14  in fixed income end includes a second user interface program  140  for a fixed income holder  8  to set subscription quantities of fixed income units  1400  and execute through the second user interface program  1400  to allow the computer device  14  in fixed income end execute the low risk monthly profit trading provided by the quasi-decentralized financial investment system  1  based on blockchain. The two types of users of the risk decomposition system can be the fixed income holder  8  and the risk trader  6 . 
     It is needed to be explained that the investment targets of the risk investment units  1200  and the fixed income units  1400  include cryptocurrency, traditional investment targets, such as stocks, bonds, futures, options, financial derivatives, or other financial products, etc. 
     The quantitative platform  16 , such as, mirror trading platform, escrow trading platform, stores selective investment strategy program  1600  for executing high leverage risk trading. 
     The smart contract  10  is connected to the computer device  12  in risk investment end, the computer device  14  in fixed income end, and the quantitative platform  16 , such as, mirror trading platform, escrow trading platform, respectively, for data exchange processes. 
     The smart contract  10  further includes risk collateral module  102  and investment interest exchange contract module  104 , wherein first monetary amount  1022  corresponding to subscription quantities of risk investment units  1200  of the risk trader  6 , and second monetary amount  1024  corresponding to subscription quantities of fixed income units  1400  of the fixed income holder  8  are stored in the risk collateral module  102 , data  1042  of Investment interest exchange contract rules between the computer device  12  in risk investment end and the computer device  14  in fixed income end, the computer device  14  in fixed income end and the quantitative platform  16 , such as, mirror trading platform, escrow trading platform, and, the computer device  12  in risk investment end and the quantitative platform  16 , such as, mirror trading platform, escrow trading platform, are all stored in the investment interest exchange contract module  104 . The smart contract  10  executes capital gains distribution of the first monetary amount  1022  and the second monetary amount  1024  stored in the risk collateral module  102  according to the data  1042  of investment interest exchange contract rules. 
     The computer device  12  in risk investment end can include but not be limited to desk-top computer, laptop, smart phone, Tablet PC, etc. 
     The first user interface program  120  included in the computer device  12  in risk investment end is for the risk taker  6  to set subscription quantities of risk investment units  1200  and execute through the first user interface program  120  to allow the computer device  12  in risk investment end execute the high leverage risk trading provided by the quasi-decentralized financial investment system  1  based on blockchain. 
     That is, the trading strategy or trading product provided by the computer device  12  in risk investment end is the financial investment product especially for the high risk taker  6 , high risk means higher returns and high leverage is suitable for the risk taker  6  to invest the tradable asset. 
     It is needed to be specifically explained that the risk taker  6  sets subscription quantities of risk investment units  1200  through the first user interface program  120  and execute, and can use fiat currency, cryptocurrency or quasi money to subscribe, wherein the quasi money subscription is such as investment points subscription, member points subscription, etc. 
     The first user interface program  120  is for the risk taker  6  to set subscription quantities of risk investment units  1200 . For example, if the unit price is 100 USTD (Tether USD), the risk taker  6  wants to subscribe 8 units, and, then, must transfer 800 USDT to the computer device  12  in risk investment end to accomplish the subscription. And, that means the risk taker  6  invests 800 USDT to execute the high leverage risk trading provided by the quasi-decentralized financial investment system  1  based on blockchain. 
     The cryptocurrency in the present invention is not limited to USDT, but also can be other cryptocurrency, such as Bitcoin, Ethereum, Ripple, Litecoin, etc. 
     In the present invention, the investment units can be established at fiat currency such as, USD, etc. The quasi-decentralized financial investment system  1  based on blockchain can convert the fiat currency to cryptocurrency to execute the trading investment. When the liquidation process of the trading investment is processed, the quasi-decentralized financial investment system  1  based on blockchain can convert the cryptocurrency to the fiat currency. Meanwhile, in the same way, the quasi currency can be used to execute the trading investment and the liquidation process. 
     In the same way, the computer device  14  in fixed income end can include but not be limited to desk-top computer, Laptop, smart phone, Tablet PC, etc. 
     The second user interface program  140  included in the computer device  14  in fixed income end is for the fixed income holder  8  to set subscription quantities of fixed income units  1400  and execute through the second user interface program  140  to allow the computer device  14  in fixed income end execute the low risk monthly profit receiving in trading provided by the quasi-decentralized financial investment system  1  based on blockchain. 
     That is, the trading strategy or trading products provided by the computer device  14  in fixed income end is specially for the fixed income holder  8  preferring stable income with low risk, low risk meaning lower returns than the returns in high leverage trading is suitable for the fixed income holder  8  to invest the tradable asset. 
     It is needed to be specifically explained that the fixed income holder  8  sets subscription quantities of fixed income units  1400  and execute through the second user interface program  140 , and can use fiat currency, cryptocurrency or quasi money to subscribe, wherein the quasi money subscription is such as investment points subscription, member points subscription, etc 
     The second user interface program  140  is for the fixed income holder  8  to set subscription quantities of fixed income units  1400 . For example, if the unit price is 1000 USTD (Tether USD), the fixed income holder  8  wants to subscribe 8 units, and, then, must transfer 8000 USDT to the computer device  14  in fixed income end to accomplish the subscription. And, that means the fixed income holder  8  invests 8000 USDT to execute the low risk monthly profit receiving in trading provided by the quasi-decentralized financial investment system  1  based on blockchain. 
     The cryptocurrency in the present invention is not limited to USDT, but can be other cryptocurrency, such as Bitcoin, Ethereum, Ripple, Litecoin, etc. 
     In the present invention, the investment units can be established at fiat currency such as, USD, etc. The quasi-decentralized financial investment system  1  based on blockchain can convert the fiat currency to cryptocurrency to execute the trading investment. When the liquidation process of the trading investment is processed, the quasi-decentralized financial investment system  1  based on blockchain can convert the cryptocurrency to the fiat currency. Meanwhile, in the same way, the quasi currency can be used to execute the trading investment and the liquidation process. 
     It is to be mentioned that under the system structure constructed by the present invention, there is a multiple leverage relationship between the subscription price of the unit price of the risk investment units  1200 , and the subscription price of the unit price of the fixed income units  1400 . 
     The multiple leverage is between 5 to 20, and the selected investment strategy program  1600  used for executing high-leverage risk trading tends not to trigger an early terminating condition and execute an early liquidation due to trader&#39;s poor performance. 
     For the example mentioned above, the subscription price of the unit price of the risk investment units  1200  is 100 USDT, and the subscription price of the fixed income units  1400  is 1000 USDT. That is, the subscription price of the fixed income units  1400  is 10 times than that of the unit price of the risk investment units  1200 . And under this situation, the multiple leverage of the high leverage risk trading provided by the quasi-decentralized financial investment system  1  based on blockchain of the present invention is 10. 
     As for the quantitative platform  16 , such as, mirror trading platform, escrow trading platform, the quantitative trading strategy is a investment method by using automated program with the help of modern statistics and mathematics to execute trading. The selected investment strategy program  1600  stored in the quantitative platform  16 , such as, mirror trading platform, escrow trading platform, of the present invention used for executing high-leverage risk trading can be one of or a combination of Artificial Intelligence programs, empirical logic programs, trading logic programs, and programs based on mathematical models. 
     A risk investment computer device used for providing a risk taker to execute the high-leverage risk trading would be executed by the selected investment strategy program  1600 , and in particular, the selected investment strategy program  1600  can be maintained and updated by a professional trading team. And that is, the selected investment strategy program  1600  can be updated and modified according to the market mechanism and changes in the market without keeping the same trading strategy. 
     The smart contract, in short, is a special protocol used in blockchain in the development of contracts, primarily to provide verification and execution of the conditions and terms defined in the smart contract. In addition, smart contracts are defined by the creator and constructed by blockchain network execution, wherein all messages related to the contract conditions and terms are automatically executed according to the actions set in the contract. 
     In the present invention, the smart contract  10  is connected to the computer device  12  in risk investment end, the computer device  14  in fixed income end, and the quantitative platform  16 , such as, mirror trading platform, escrow trading platform, respectively, for data exchange processes. The smart contract  10  further includes risk collateral module  102  and investment interest exchange contract module  104 . 
     For more details, the first monetary amount  1022  corresponding to subscription quantities of risk investment units  1200  of the risk trader  6 , and the second monetary amount  1024  corresponding to subscription quantities of fixed income units  1400  of the fixed income holder  8  are stored in the risk collateral module  102  of the smart contract  10 . As for the example mentioned above, the first monetary amount  1022  invested by the risk trader  6  is 800 USDT, and the second monetary amount  1024  invested by the fixed income holder  8  is 8000 USDT. 
     The investment interest exchange contract module  104  stores data  1042  of investment interest exchange contract rules corresponding to the computer device  12  in risk investment end, the computer device  14  in fixed income end, and the smart contract  16 . 
     The data  1042  of investment interest exchange contract rules records various caution notes of the financial investment, and related payment and disbursement, profit-splitting, and so on. 
     According to the data  1042  of investment interest exchange contract rules, the smart contract  10  executes a distribution of profits on the basis of the first monetary amount  1022  and the second monetary amount  1024  stored in the stored in the risk collateral module  102 . 
     Through the structure of the smart contract  10 , the distribution of profits is automatically executed according to trading terms of the data  1042  of investment interest exchange contract rules, and the trading terms of agreement are immutable, and all the activities are actively collected in the blockchain for viewing, which are traceable, immutable and irreversible, and enable the computer device  12  in risk investment end and the computer device  14  in fixed income end to execute profit sharing according to the smart contract, effectively preventing any respective parties from not executing contract and avoiding the risk of financial fraud. 
     An embodiment is to describe practical investment operation processes based on the quasi-decentralized financial investment system  1  based on blockchain of the present invention. 
     The quasi-decentralized financial investment system  1  based on blockchain of the present invention is a quasi-decentralized financial investment system to satisfy requirements of the computer device  12  in risk investment end and the computer device  14  in fixed income end, and simultaneously to integrate the high risk investment strategy for the computer device  12  in risk investment end, and the low risk investment strategy for the computer device  14  in fixed income end. 
     That is, the purpose of the cryptocurrency invested by the risk taker  6  through the computer device  12  in risk investment end is to increase leverage investment to maximize profits, and the cryptocurrency invested by the fixed income holder  8  through the computer device  14  in fixed income end is collateralized to receive fixed interest rate. 
     In this embodiment, if a contract period of the smart contract  10  of the quasi-decentralized financial investment system  1  based on blockchain is 6 months and the investment performance of the smart contract  10  can guarantee and reach an annualized rate of return of 12% for the fixed income holder  8  through the computer device  14  in fixed income end, it needs 1000 USDT invested by the fixed income holder  8  to subscribe 1 unit of the investment product. 
     That is, after the fixed income holder  8  invests 1000 USDT to subscribe 1 unit of the investment product, the 1 unit earns the fixed income holder  8  10 USDT risk free per month in interest for 6 months, or, after 6 months, the smart contract  10  is terminated and the fixed income holder  8  receives 60 USD for interest payment (contract period, half year, annual interest rate, 12%). And The 1000 USDT invested by the fixed income holder  8  as the collateralized property is stored in the risk collateral module  102 . The interest payment made every month, or made once after the smart contract expiry date can be read in the data  1042  of investment interest exchange contract rules of the smart contract  10  to make an appointment. 
     It is needed to be mentioned that the annual interest rate 12% for the fixed income holder  8  in the computer device  14  in fixed income end is not negotiated and determined by the computer device  12  in risk investment end and the computer device  14  in fixed income end, and, however, the annual interest rate is changed based on the increased demand. If the trend of the overall cryptocurrency gradually has slowed down, and even begins to enter a slow-down and consolidation phase, the market liquidity and arbitrage space become smaller; the annual interest rate may be less than 12%. 
     On the other hand, the risk taker  6  in the computer device  12  in risk investment end just needs to pay a small amount of funds to get the encrypted assets lent by the fixed income holder  8  through the computer device  14  in fixed income end, and, through high multiple leverage, can maximize the profits by using the selected investment strategy program  1600  of the quantitative platform  16 , such as, mirror trading platform, escrow trading platform. 
     In this embodiment, the risk taker  6  in the computer device  12  in risk investment end needs to invest 1000 USDT to subscribe 1 unit of the investment product. That is, after subscribing 1 unit of the investment product, the risk taker  6  can own the investment rights of the encrypted assets (encrypted assets, 1000 USDT) lent by the fixed income holder  8  in the computer device  14  in fixed income end, and the leverage ratio is 10 times. 
     Generally speaking, the investment funds (100 USDT) invested by the risk holder  8  in the computer device  12  in risk investment end will be divided into the following 3 uses: 
     1. For example, 60% of the investment funds (60 USDT) is used as loan interest paid to the fixed income holder  10  through the computer device  12  in fixed income end. 
     2. 30% of the investment funds (60 USDT) is used as the margin stake, and serves as the margin stake for the selective investment strategy program  1600  to approach profit or loss. When the strategy is terminated, there is a positive return, the margin stake will be returned to the risk holder  6  in the computer device  12  in the risk investment end. 
     3. The platform of the quasi-decentralized financial investment system based on blockchain receives platform fee from both the fixed income holder&#39;s and the risk taker&#39;s investment. 10% of the investment funds (60 USDT) is used as the platform management fees. 
     If the selective investment strategy program  1600  is to receive a 30% annual return, the computer device  12  in risk investment end can receive 150 USDT profit during the 6-month contract period, and, however, the computer device  12  in risk investment end only invests 100 USDT, but can invest 1000 USDT lent by the computer device  14  in fixed income end and receives the profits by using the selected investment strategy program  1600  to earn a 30% annual return. In other words, this means that the investment return rate in the computer device  12  in risk investment end is the annualized return rate which is 100%. 
     It should be noticed that if the performance of the selective investment strategy program  1600  is negative or under expected, it is possible to execute a liquidation process and the risk taker  6  in the computer device  12  in high risk investment end will lose all of his assets, 100 USDT, and, however, the smart contract  10  will always guarantee that the fixed income holder  8 , the asset lender, receives his interests during settlement periods. 
     As mentioned in the above, the multi-leveraged investment product provided by the quasi-decentralized financial investment system  1  based on blockchain of the present invention is suitable for the risk takers  6  who is pursuing high-risk and high-reward. The risk taker  6  initially inputs a small amount of cryto assets to gain access to a greater amount provided by the fixed income holder  8  in the computer device  14  in fixed income end, and to gain full rights to the investment equity. 
     The computer device  14  in fixed income end provides crypto assets to the the selective investment strategy program  1600 . At the end of the contract period, the fixed income holder  8  can recover 100% of his lending crypto assets without the risk of loss. 
     In the embodiment, the fixed income holder  8  in the computer device  14  in fixed income end can earn a stable 12% annual return rate within half a year. The risk taker  6  in the computer device  12  in risk investment end does not to pledge an over-collateralized amount of crypto assets to the selective investment strategy program  1600 , and can own the investment rights of the encrypted assets 10 times than the crypto assets invested by the risk taker  6  to maximize the profits. 
     By extending the concept of a decentralized lending platform, the quasi-decentralized financial investment system  1  based on blockchain of the present invention brings in more traditional investors with conservative investment styles, and can simultaneously satisfy investors with different risk tolerances to meet two extreme needs of two types of investors—the fixed income holder who pursues low-risk, stable returns, and the risk taker who is willing to take on more risk for higher returns. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed embodiments. It is intended that the specification and examples be considered as exemplary only, with a true scope of the disclosure being indicated by the following claims and their equivalents.
