What is the mode of mine pool
ore pool cost
at present, the allocation modes of ore pool mainly include PPS, PPS +, FPPS, PPLNs and solo mode
in the corresponding allocation method, the mine pool charges part of the income of the miners at a certain rate as the mine pool fee
PPS: the income is stable. As long as the mining machine works normally, there will be income. The income is related to the submitted workload, and has nothing to do with the lucky value of the ore pool and the transaction fee
PPS + (pay per share plus) settlement method is an improvement on the traditional PPS settlement method. Based on the traditional PPS settlement method, the distribution of miners' fees is increased
FPPS: full PPS, which allocates all block income including transaction fees. Compared with the traditional PPS settlement mode (no transaction fee allocation), it can increase the income by 10% - 20%
under the PPLNs (pay per last n shares) settlement mode, every effective block found in the ore pool is allocated according to the proportion of user computing power in the pool computing power in the past n difficulty cycles. In this way, the income of miners is related to the output of ore pool. The income of miners is unstable, but the long-term average income is higher
in solo settlement mode, all the income is distributed to the miners who dig out the block, and other miners do not participate in the distribution. The mine pool charges very little handling charge, which is used for the operation and maintenance of the mine pool< How to choose a mine pool:
1< Secondly, choose your distribution mode, pursue stability or high income. It is generally recommended to choose PPS or PPLNs of large ore pool< Finally, according to the distribution mode, select the supported ore pool, and choose the one with fast connection speed and good income
4. In addition, 1-2 spare ore pools are selected for emergency use.
income distribution
mode, which is created by AA mining pool. The optimized combination of traditional PPLNs, pplnt and prop modes makes it more accurate and efficient in
computing power
and income distribution. The concrete intuitive embodiment is that the income obtained from digging blocks is accurately distributed, and the long-term mining improves the miners' income.
Excavator generally has three modes: fine mode, ordinary mode and heavy load mode. The use of three modes: fine mode - for slope leveling fine work, ordinary mode - for the general work of mping and loading, heavy load mode - for fast loading or large amount of soil operation. It usually works in normal mode
Generally, it's OK to drive in comfort mode. If you drive in the urban area, it's recommended to use comfort mode. If you drive at high speed, it's recommended to use economy mode. If you switch to economy mode, the car will save more fuel. If you overtake at high speed, it's recommended to use comfort mode
Economic mode is also called eco mode. Eco mode pursues economy, environmental protection and practicability, which can be divided into active driving mode and non active driving modeeco mode is relatively fuel-efficient, but in the process of climbing, it is recommended not to turn on Eco, if you do not want to use it, you can turn it off by yourself
the motion mode can be switched at will ring driving, and the gearbox can shift freely, but there will be a certain delay in shifting in the motion mode, and the engine will keep at high speed for a long time, so that the engine can obtain a very large output power
sport mode is usually used in climbing and fast overtaking. Now many models are equipped with sport mode, but it is not recommended to use it under normal driving conditions. In sport mode, the fuel consumption of the car will increase instantaneously
There are four different driving modes for drivers to choose from: quiet and stable "EV pure electric mode", efficient and energy-saving "eco economic mode", stable "normal standard mode" and powerful "Sport mode"1. External mode:
external mode is also called sub mode, corresponding to user level. It is the data view of the database seen by one or several users, and it is the logical representation of the data related to an application
The
outer schema is a subset derived from the schema, which contains the part of the data that a specific user is allowed to use in the schema. The user can describe and define the data records corresponding to the user through the external schema description language (external schema), and can also use the data manipulation language (DML) to process these data records. External schema reflects the user view of database
2. Internal mode:
internal mode is also called storage mode, corresponding to the physical level. It is the internal representation or bottom description of all data in the database, and the logical description of the lowest level of the database. It describes the storage mode and physical structure of data on the storage medium, corresponding to the database actually stored on the external storage medium. Internal schema is described and defined by internal schema description language, which is the storage view of database
3. Pattern:
pattern, also known as conceptual pattern or logical pattern, corresponds to conceptual level. It is a global logical structure constructed by the database designer according to a unified point of view. It is a general description of the logical structure and characteristics of all data in the database, and a common data view (global view) for all users
it is described and defined by the data schema description language (DDL) provided by the database management system, which reflects the overall view of the database system
external schema, also known as subschema or user schema, is the description of the logical structure and characteristics of local data that can be seen and used by database users (including application programmers and end users), the data view of database users, and the logical representation of data related to an application
extended data:
a database has only one internal mode
a table may be composed of multiple files, such as data files and index files
It is an effective method for DBMS to organize and manage the data in the databasethere are also RD and AR modes commonly used.
- RD is the computer randomly selects more than ten heroes among all the heroes for both sides to choose from. In this mode, some entertainment heroes will not appear, such as bombers
- AR mode is that all people randomly choose heroes
