How to use EOS mining

1.

EOS: EOS can be understood as enterprise operation system, which is a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture introced by EOS software, which aims to realize the performance expansion of distributed applications. Note that it is not a currency like bitcoin and Ethereum, but a token based on the EOS software project, known as blockchain 3.0

The main features of

EOS are as follows:

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of blockchain, it supports multiple applications to run at the same time and provides the underlying template for the development of DAPP

EOS solves the problems of delay and data throughput by means of parallel chain and dpos. EOS can process thousands of data per second, while bitcoin has about 7 transactions per second, and Ethereum has 30-40 transactions per second

There is no service charge for EOS, and the general audience is more extensive. The network and computing resources needed to develop DAPP on EOS are allocated according to the proportion of EOS owned by developers. When you have EOS, it is equivalent to having computer resources. With the development of DAPP, you can lease your EOS to others. From this point alone, EOS has a wide range of value. To put it simply, if you have an EOS, it is equivalent to having a set of rent to collect rent for others, or having a piece of land to rent for others to build a house. digital currency exchange "currency exchange"

development prospects

through a more in-depth understanding of EOS, EOS is quite valuable for investment. First of all, as the first to launch smart contracts, ETH runs smart contracts on eth, which is not free and depends on your gas. If gas runs out, the contract will stop. According to people who have used eth trading platform, it runs slowly and is very expensive, However, there is no such problem in EOS. The operation contract on EOS depends on the number of EOS you have. The more EOS you have, the more you can rent. With the continuous development, the more expensive the price will be; Secondly, it's very simple to develop DAPP on EOS, and you don't need to write many moles, because EOS itself builds the bottom mole for developers, which provides a platform and greatly reces the threshold of development; Thirdly, as an ordinary investor, owning EOS is equivalent to owning real estate, which can be used to rent and earn money. With the development of DAPP, the number of users increases, and the price increases irresistibly

EOS is a public chain system at the bottom of blockchain developed by block. One, which is specially designed to support decentralized application of Commerce, and its code is open source

bitcoin is called blockchain 1.0 because it opens up the world of digital cryptocurrency and takes a decisive step from 0 to 1

Ethereum is known as blockchain 2.0, because it provides Turing complete virtual machine that can run smart contracts, bringing unlimited possibilities

and EOS is called blockchain 3.0, why? Two words: performance

The positioning of EOS is the slogan of its home page:

English: the most powerful infrastructure for decentralized applications

Chinese: the most powerful decentralized application infrastructure

EOS expects to be an enhanced version of Ethereum, a high-throughput intelligent contract platform

although Ethereum has complete functions, it is limited by its design choice. Due to the block output speed of 15 seconds, the transaction throughput is far from large-scale practical level, which is only about 30 ~ 40tps (transaction / s). EOS, on the other hand, has chosen a different technology route, with the goal of achieving a considerable million TPS, which is quite attractive considering visa's actual processing speed of 1700tps

consensus mechanism of EOS

the reason why the throughput of bitcoin and Ethereum is so low is that they are constrained by the application scenario they envision and the consensus mechanism they choose for the scenario - both of them assume that the environment in which the system runs is totally untrustworthy, so they both adopt the consensus mechanism of proof of work

consensus, as the name suggests, is to reach a unified understanding of something - for blockchain, something refers to the confirmation of the transaction - any node to submit a transaction needs everyone's approval

the pow mechanism currently adopted by bitcoin and Ethereum is the design of the legendary Nakamoto Tsung. Under this mechanism, in order to obtain the bookkeeping right and digital currency reward, miners need to constantly dig for the compliant hash value, and confirm and package the transaction data through the consensus of hash value. POW has no access threshold, and any node has equal rights to participate in bookkeeping. Of course, the probability of winning is related to computing power:

the price of ram is based on Bancor algorithm, that is, it is regulated by market supply and demand: if the supply of ram exceeds the demand, more EOS certificates are needed to buy ram, At this time, more EOS certificates can be obtained by selling ram

memory is a consuming resource, which cannot be redeemed and can only be bought and sold. Take the issue of currency on EOS as an example. At present, the issue of currency requires 20m of memory. An EOS can buy 20KB. According to the current storage price, issuing a currency will consume 1000 EOS. This is the source of EOS memory consumption

"Transaction is mining" is a typical platform operation mode. Users mine through transactions. Some platforms will issue their own tokens as rewards for users' trading behavior

Relevant introction:

in June 2018, the cryptocurrency exchange fcoin put forward the concept of "trading is mining", and in a short period of time, the daily trading volume rose to the first in the world, triggering a war between exchanges

"transaction is mining" is actually a return mechanism of personal transaction fees based on platform currency. Strictly speaking, there were similar playing methods before the establishment of fcoin. For example, bibox had a mechanism to return a certain proportion of fee income to platform currency holders

extended data

fcoin's "transaction is mining" is repackaged. Following the allocation rules of bitcoin mining, 51% of platform currency ft is taken as the mining reward pool. Through "mining (trading on fcoin)", FT is graally unlocked. Once 51% of FT is fully fed back, "mining" is automatically terminated

in terms of specific implementation, fcoin trading means mining starts at 0 o'clock every day (GMT + 8), and the transaction fees generated by users will be converted into ft for accumulation every hour. The conversion price is calculated according to the average price of FT in that hour (the average price is calculated as total transaction amount / total trading volume)

6. Planet coin XQ
ccoin is the proof of the rights and interests of EOS planet community, which has an innovative "invite and dig" mechanism. It is said that the total amount is 1 billion, and there will be no additional issuance. I don't think it's very useful for the time being. It's equivalent to a new project. One day, the platform will be able to sell

7. Let me give you a metaphor. Using SLR camera (including 500D) is like driving a car. It's not enough to know how to use it. You have to master it to use it flexibly
you must be familiar with the meaning of each function key and how to adjust it. Look at the instructions bit by bit and make sure you understand them. On this basis, the following questions are explored:

1. What is sensitivity? How to adjust and adjust the influence of sensitivity on photo quality and exposure parameters? When is the sensitivity adjusted< What is the shutter speed? How to adjust the shutter speed? Shutter speed synchronized with flash? What is the minimum shutter speed required for end stabilized cameras? What is the shutter speed of a moving object? When is shutter priority
3. What is the aperture of the lens and how to adjust it? How does aperture affect depth of field? The influence of aperture on flash distance? The influence of aperture on imaging quality? When is aperture first< What is the focal length of the lens? 5. What is white balance? What is the criterion? How to adjust< What is exposure compensation? How to adjust? When do you use it? There are several ways to measure light by camera. What are their characteristics and shortcomings? In what cases< 7. Use of flash. What determines the operating distance? How to fill the light< 8. Adjustment of image size and resolution, image format

after understanding the above problems, understand the characteristics of automatic file P file a file s file and m file, then you can shoot

practice while shooting

8. I don't know what you want to ask specifically. If you want to set query conditions, you can set criteriaentity in the assignment. First set the persistent entity object corresponding to the query entity, and then set query conditions. For example, add three lines to the assignment, criteriaentity / expr on the left of the first line/_ Property, setx (constant) on the right side of the first line, criteriaentity / expr on the left side of the second line/_ OP, setting on the right of the second line = (constant), criteriaentity / expr on the left of the third line [1]/_ Value, the third line right female (constant), according to this assignment is OK, there are instructions in the tutorial, I calm down to see the line, not very difficult!
