what is Ethereum:
Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want
advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum
what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application
The design of Ethereum is very flexible and adaptable
Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields
blockchain applications of Ethereum
Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc
Ethereum has achieved more than 100 blockchain applications by many start-ups
Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged
the relationship between Ethereum and blockchain:
Ethereum is a programmable blockchain
Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes
in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
This is two different concepts. According to different standards, blockchain can be classified into three categories:
& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain
&# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain
&# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain
the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process
short video platform that can make money, I need to say again, it is really reliable. Today, I am going to share with you a short video platform called tubing, jitter and block chain. Tiktok Kwai br />1, platform features are now short video platform, so many people finally won the jitter, and no quick response. But if a new short video platform wants to promote and get more traffic, it is bound to invest an initial capital to guide and support the content procers on the platform. Although we can't guarantee that this platform will continue, for us, even a novice who has just contacted the Internet, we can earn the first money from these short video platforms by moving. Is it worthless for us to release so many gimmicks on this platform? Of course not. In the field of blockchain, there is a concept called "decentralization". This concept is reflected in the community convention of short video of firebull, which has become such a paragraph: "firebull video community users are completely autonomous, without official management and audit, and are completely maintained through the user's behavior and community standards." Of course, there can't be a completely unregulated platform right now. But we can feel from this concept that the audit of this platform will be more relaxed than that of some old platforms. And with the addition of the concept of blockchain, users' behaviors on this platform, including watching, liking and commenting, are no longer just a simple number. These behaviors can directly increase the income of video owners. 2. Access to software firebull video is now online in the Android App store, but users on the IOS side can't find it in the Apple App Store yet. They can only download it by scanning the code. You can scan the following QR code to download and register
firebull video app to download: firebull video
however, the app downloaded by Apple mobile phone through scanning code will encounter the same problem as above, and the solution to this problem is extremely simple
IOS users first enter the settings interface, then click general, and then find the option of "device management"
in this option, we choose to trust the app, and then we can use the proct on Apple's mobile phone
after logging into this interface, we can start to register the account of firebull video
a new invitation code is required to register on firebull video, because the platform has a new policy. Here is an invitation code for you to fill in: 1650333
on the main page of short video, we can see that firebull video will directly provide a revenue channel for video owners through the function of "like". Users can praise the short video and then directly reward the video host with 10 virtual currencies. However, this reward will be different from that of other we media platforms, because all the virtual money spent in this reward behavior is provided by the platform, rather than the virtual money obtained after users recharge and purchase. This means that the content procers of this platform directly get the pink of the platform revenue, rather than waiting for the users to pay for it. It is precisely because users can conct a kind of free reward behavior, as long as the video can attract the attention of users, we have a great chance to obtain revenue. 3. User income because it is a short video platform related to blockchain, huoniu short video also adds the function of mining
on this platform, each user can get the virtual currency provided by the platform through the app. And from the above figure, we can see that as long as we watch and reward videos, we have a chance to get more platform virtual coins. This is the welfare period policy of the new platform, which means that the platform will not only encourage content procers to create content on the platform, but also encourage users to conct "user behavior" on the platform. Under this al stimulation, both content procers and users can guide more traffic for the platform. It is also this kind of welfare policy that both new and experienced people have the al means to obtain benefits. If we operate the platform as a user, there are only two ways to obtain virtual currency: one is to conct user behavior and watch, share and reward videos. As we can see in the above figure, there are 10 signs like small fire buffalo in the reward function. Users will consume a small fire bull by clicking reward, and each small fire bull will increase the probability of procing virtual currency. When we've consumed all 10 buffaloes, we'll get one for every 5 minutes we watch the video. In order to encourage users to watch and reward. Firebull video app Download: firebull video
the second method is to get virtual currency of platform reward through innovation. Because the platform is in an initial stage, it needs a lot of traffic support, so the platform will also have more support for pull new. Every time you pull a friend, you will get 80 virtual coins provided by the platform, and new users must fill in the invitation code when they register
you can fill in: 1650333
and we need to use Ethereum wallet to withdraw the virtual currency on the firebull video. Although the process will be complicated, with the trust endorsement of Ethereum, it is a cash withdrawal guarantee for users. However, this currency has not been online yet, so it can not be directly converted into RMB. 4. Dividend income
compared with the platform virtual currency that can't directly connect with RMB, I recommend you to directly become content procers to obtain income. For content procers, the platform will first calculate the virtual currency we get on the day of our short video, and then the platform will take out 80% of the revenue on the day, and give us dividends according to the proportion of virtual currency we get. And the dividend is directly in the form of cash dividends to our account, and is settled by the day. That is easier than pulling new harvest virtual currency or moving bricks to get dividend income
in this new platform, it is definitely the best that we can create our own content. If we can't create our own content, we can use this technology to find content that can attract a large number of users on other short video platforms, and then transport these content to the platform of firebull. If we want to avoid the homogenization of moving content, the users who have started the YouTube brick moving project can directly put their prepared videos on this platform. Of course, if some friends rely on their own wool traffic to operate the above mentioned pull new project, then we can also guide this batch of traffic to operate for our own video users, so as to increase our dividend income. However, whether it is to pull new or rely on traffic to improve our video dividends, we should try not to use technology tools to decode and brush. Because the benefits offered by the new platform are relatively high, if we use scientific and technological tools for batch operation, it is easy to be monitored by the platform because of high profits. Once it is found that cheating is used, we will be banned by the platform. Generally speaking, this is a project worthy of our operation. Although we can't ensure that this platform can continue to develop, we can also make a good profit in the welfare period of several months as long as we operate it properly.

Leadership refers to the ability to make full use of human resources and objective conditions within the jurisdiction to achieve what is needed at the minimum cost and improve the efficiency of the whole group. The common leadership development methods include ceo12 leadership promotion, EMBA and EDP projects, etc
the research on leadership begins with the research on leadership. From the end of the 19th century to the beginning of the 20th century, the leadership trait theory focused on the personality traits of leaders, to the 1940s, the leadership behavior theory explored the specific behaviors of leaders in the process of leadership and the influence of different leadership behaviors on subordinates
The contingency theory of leadership (situational theory), which studies the potential influence of situational factors related to leadership behavior on leadership effectiveness in the 1960s, and the later leadership attribution theory, transactional and transformational theories, have graally expanded from indivial research on leaders' personality traits and behavior to the influence of situational interaction in the whole organization
the basic principles of leadership are as follows:
leadership is the art of how to be a person, not how to do things. Finally, the ability of a leader is determined by personal quality and personality. Leaders succeed through the efforts of the employees they lead. The basic task of leaders is to build a highly conscious and proctive work team
leadership ability is the sum of indivial quality, thinking mode, practical experience and leadership methods of leaders, which affect the effect of specific leadership activities. Leadership ability is the core of leaders' quality< br />
It can only be explained from the concept
Bitcoin is a kind of network virtual currency, which can buy real-life goodsit is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
in 2013, the US government recognized the legal status of bitcoin, which led to a sharp rise in the price of bitcoin
In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuanin front of the article: the video version is slightly different from the text version. If you want to see my affectionate interpretation, please see the video version (meow understands blockchain phase 22 | sharding: Ethereum is too slow, "disk" him!), The logic of thinking is strange. Please see the extended version
recently, Ethereum has shown an overwhelming positive trend e to the Constantinople upgrade, while Ethereum's upgrade road is like upgrading and fighting monsters, falling into rabbithole. No one knows how deep the hole is. Since it is a long way to go, it is of vital importance to make every step well and accurately. After overcoming this difficulty, Ethereum's next technical difficulty, sharding fragmentation, has been put on the table again. This issue of "meow understands blockchain" will take you into sharding, the magic weapon that makes Ethereum fast
what is sharding
slicing technology is not a new concept. At first, it is an optimization scheme for large central database. Specifically, it divides the data in large database into many shards according to certain rules, and then stores these data in different servers to rece the data access pressure of each server, So as to improve the performance of the whole database system
let's take a small popular example:
for example, meituan, Didi taxi and other software that we often use can be divided according to the "city". Because the data of different cities do not need to communicate, the data of different cities can be stored in different databases, so that the database server can be deployed to the nearest node from the corresponding city, Can also improve the speed of access, why not do it
from the above examples, we should have a preliminary understanding of the concept of fragmentation. What about fragmentation in blockchain scenarios
taking Ethereum fragmentation as an example, in the original single chain system, the overall performance of the public chain depends on the performance of a single node. After fragmentation, each node only needs to undertake the work of the whole network, and each fragmentation works in parallel. According to vitalik, each shard is like a separate galaxy, and each fragmentation is like an independent universe, In this way, the efficiency will be improved naturally! Originally, the total network TPS of Ethereum chain was about 20. Now, if it is increased to 100 pieces, the total network TPS can be increased to 2000. Similarly, the total network capacity will be increased to 100 times of the original
"each node only needs to undertake part of the work of the whole network", which will lead to several major problems. 1. How to determine which piece of work this node is responsible for? 2. Which transactions should be classified into which segments? 3. Does each node only need to store its own transaction information (ledger)
according to the implementation of the above problems, we can divide the fragmentation into three types: network fragmentation, transaction fragmentation and state fragmentation
Network fragmentation: how to divide the nodes of the whole network into different partitions
transaction segmentation: how to divide the whole network transactions into different segments
State fragmentation: how to make each node only maintain the account book in its own fragmentation without affecting the security of the whole system
the difference and connection between main chain and fragmentation chain
we have understood the types of fragmentation, so what's the difference between main chain and shard chain
turn left | turn right
the realization of Ethereum fragmentation is a long process. Even vitalik himself said that it will be graally realized by stages. We'd better look forward to whether fragmentation can move from theory to practice
