What is pool trusteeship
because the probability of a single miner digging a block is very small, after all, it takes a lot of computing power to dig a block in 10 minutes. Even if there is such a large amount of computing power and the ability to dig, there are many competitors. So it becomes a game of 0 and 1. And the emergence of the mine pool is to break the 0 and 1 play. The computing power of a mine pool is a collection of many miners' computing power, which is far more likely than fighting alone. Every time you dig a block in the mine, you will be rewarded to the indivial according to the percentage of the calculation power of your mining machine in the total calculation power of the mine, and there will be no unfair situation.
Trusteeship has two meanings:
1. One or more member states are entrusted by the United Nations to manage the areas that have not yet gained autonomy under the supervision of the United Nations
2. Entrusted management or custody
for example, enterprise trusteeship means that the owner of enterprise assets entrusts the management right and disposal right of the whole or part of the assets of the enterprise to other legal persons or indivials for management in the form of contract under certain conditions and within a certain period of time, thus forming the mutual interests and restrictive relationship among the owner, the trustee, the operator and the procer
another example is bank trusteeship, which means that the bank, as a third party, acts on behalf of the interests of the asset owner in accordance with laws and regulations and the trusteeship contract, engaging in custody of the assets, clearing the funds under the name of the assets, accounting and valuation of the assets, and supervising the investment operation of the manager, so as to ensure the interests of the asset trustor and collect the trusteeship fee

Second, only transfer the management right, not the ownership, which is concive to the "separation of the two rights", to avoid too much interference from the asset owners, and to better reflect the principle of independent management of modern enterprises Thirdly, ring the period of entrusted operation, we can engage in both proct operation and asset operationEnterprise trusteeship is a new thing in China's economic life in recent years, which is a new form of capital management. At present, the reform of property right system of state-owned enterprises lags behind in China. Trusteeship is a flexible way to invigorate state-owned enterprises, and also a way to restructure assets of listed companies
commercial banks have a wide range of custody business, mainly including: safe custody of entrusted assets; Fund clearing and securities delivery under the name of entrusted assets; Supervise the investment operation of entrusted assets; Timely report the investment operation and relevant information of entrusted assets to relevant departments and clients; Record the assets, liabilities and investment of the entrusted assets; Value the securities held by entrusted assets according to relevant requirements; Objectively and fairly analyze the investment operation of the entrusted assets, and provide relevant analysis information to the client; Other business related to entrusted asset custody
for the client, the entrusted asset custody business takes into account both the profitability and safety of investment, and can enjoy the financial services provided by the client. At the same time, since the custodian is responsible for the account and clearing of funds, it can effectively avoid some disputes in the process of entrusted financial management. Therefore, the entrusted asset custody business of commercial banks has broad market prospects.
in practice, there are also different modes of trusteeship management, which can be summarized into three types
1. The trusteeship management of enterprise property rights. Trusteeship management takes the property right of the enterprise as the subject matter. According to certain laws, regulations and policies, the entrusting party signs a contract with the entrusted party, takes certain conditions as the premise, and takes a certain price as compensation, and transfers all the property rights of the enterprise to the entrusted party for disposal. The trusteeship management of enterprise property rights is essentially a kind of transaction of enterprise property rights in the non-public market. Under the condition that the property right market has not been perfected, it has become a flexible way of property right circulation
2. The trusteeship management of state-owned assets. This kind of trusteeship means that the state-owned assets management department authorized by the government, as the representative of the owner of state-owned assets, entrusts the state-owned assets of state-owned enterprises and corporate enterprises to the entrusted party in the form of contract. Due to the nature of ownership, in this kind of trusteeship, the object of trusteeship can only be the management right of the enterprise, not the property right of the enterprise. This is a kind of economic behavior with short-term output as the operation goal. The entrusted parties can only maintain and increase the value of state-owned assets by changing the operation mechanism of the trusteeship enterprise and adopting other means within the scope of the contract
3. Trusteeship management of state-owned enterprises. In this mode, a certain department or organization takes over a part of the loss making small and medium-sized state-owned enterprises, and through comprehensive transformation, changes the original enterprise structure and asset structure, so as to realize the reallocation of resources. The trustee fully accepts the trusteeship enterprise, including all property, all staff and debts of the enterprise. In our opinion, strictly speaking, trusteeship refers to the transfer of the right of operation and disposal of the enterprise assets or the enterprise legal person property (whole or part) by the subject of the property right of the enterprise legal person (the trustor) through the trust agreement. The legal person (the trustor) who has strong management ability and can bear the corresponding business risks shall manage and deal with the entrusted assets by the trustor, It is a kind of management mode to ensure the value preservation and appreciation of enterprise assets. The essence of enterprise trusteeship is to introce a trust mechanism in line with the rules of market economy in clarifying the relationship between the rights and responsibilities of the owners and managers of enterprise assets. The essence of enterprise trusteeship comes from trust< First, it provides a broad stage for a large number of entrepreneurs who have vision and management ability but can't afford to spend a lot of money to buy large assets
Second, only transfer the management right, not the ownership, which is beneficial to & quot; Separation of two rights;, Avoid too much interference from the owners of assets, and better reflect the principle of independent operation of modern enterprises
thirdly, ring the period of entrusted operation, we can engage in both proct operation and asset operation

what you said is reasonable.
(1) managed code: the. Net environment provides many core runtime services, such as exception handling and security policy. In order to use these services, we must provide some information code (metadata) for the running environment, which is called managed code. All C + + is managed by default, but visual c + + is not managed by default. You must use the command line option (/ CLR) in the compiler to generate managed code
(2) managed data: managed data is closely related to managed code. Managed data is the data that is allocated and released by the garbage collector running in the common language. By default, C #, visual basic, and data are managed data. However, by using special keywords, C # data can be marked as unmanaged data. Visual C + + data is unmanaged by default, even when using the / CLR switch
(3) managed class: although visual c + + data is unmanaged by default, when using the managed extension of C + +, you can use the__ The "GC" keyword marks a class as a managed class. As the name shows, it means that the memory of the class instance is managed by the garbage collector. In addition, a managed class can also be a member of. Net framework. The advantage is that it can interact with classes written in other languages correctly. For example, managed C + + classes can inherit from visual basic classes. However, there are also some limitations, such as that managed classes can only inherit from one base class. It should be noted that both managed and unmanaged classes can be used in managed C + + applications. The unmanaged class here does not refer to the standard C + + class, but uses the__ Class of nogc keyword.
