The value of Ethereum founder V God

1. Vitalik buterin, the founder of Ethereum and the younger brother of the post-90s generation, is known as "V God" in the Jianghu
bitcoin is a digital currency designed by Nakamoto in 2009. The identity of its founder "Nakamoto" has always been a mystery. Rumors about "father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura. Matcha exchange can find out more about Ethereum bitcoin

Q: What is bitcoin bifurcation and why

A: the reason why bitcoin bifurcates is that the underlying technology of bitcoin is blockchain. Some people begin to think that bitcoin's block capacity is too small and there are always congestion. So they ask for bitcoin's upgrade and expansion. Some people think that bitcoin's function is too single and its future development is not optimistic, So these people ask bitcoin to have the function of building DAPP (decentralized application), and some support it, while others oppose it. This kind of divergence can be understood as the bifurcation of bitcoin

Q: the classification of bitcoin bifurcation

A: there are two kinds of bifurcations of bitcoin, one is soft bifurcations, the other is hard bifurcations, so what is soft bifurcations

Q: the formation principle of soft bifurcation

A: soft fork refers to optimizing and modifying bugs in the original bitcoin network to improve the capacity of the block, such as 2m, 4m or 8m, 16m. The segwit lightning network is the mainstream solution, which is equivalent to a traffic jam on the main road, and the development team will build an auxiliary road to help the main road to divert congestion

this is a mild solution, which can make the original bitcoin network compatible with the network after soft bifurcation, and the main transaction of bitcoin is still on the main chain

Q: disadvantages of soft bifurcation

A: of course, there are disadvantages of soft bifurcation, that is, it can only solve the temporary congestion problem, and after the implementation of soft bifurcation, it can only keep the network unobstructed for a few years. In the future, it needs continuous expansion, which has an impact on the stability of the system

Q: what is hard bifurcation and its formation principle

A: another solution is hard fork, which means to upgrade the bitcoin system again, change the height of the block completely in the form of code, and take bitcoin unlimited as the mainstream solution. Generally speaking, it is equivalent to a traffic jam on the main road. We directly abandon this road and find a place to build a three-dimensional transportation hub on the ground and underground. All new cars use this transportation system, which changes the block size of the bitcoin network and optimizes the processing speed of the network

Q: what are the disadvantages of hard bifurcation

A: but hard bifurcations also have disadvantages, that is, they are not compatible with the original bitcoin system, which requires all people in the bitcoin network to support hard bifurcations. If some people do not support hard bifurcations, there will be two versions of bitcoin network, which will proce two bitcoins. The blockchains of the two bitcoins form a competitive relationship, This kind of internal friction will lead to greater price volatility and uncertainty of bitcoin's future situation

Q: a classic case of bitcoin bifurcation

A: Eth and etc are typical cases of hard bifurcation. The Dao project is a crowdfunding project initiated by slock.it, a blockchain Internet of things company. It was officially released in May 2016. As of June of that year, the Dao project has raised more than $160 million. It wasn't long before the Dao project was targeted by hackers. Because of the huge loopholes in the smart contract, the Dao project was transferred to ether coin with a market value of 50 million US dollars

in order to recover the assets of many investors and stop the panic, vitalik buterin, the founder of Ethereum, finally proposed the idea of hard bifurcation, and finally completed the hard bifurcation in block 1920000 of Ethereum through a majority vote of the community, rolling back all the Ethereum coins occupied by hackers

even though Ethereum hard bifurcates into two chains, some people who believe in the tamper proof property of blockchain still stay on the original chain of Ethereum classic. Today, Ethereum (ETH) and Ethereum classic (etc) are ranked in the top 20 in the global cryptocurrency market value, which is one of the reasons why they are regarded as classic cases in the field of hard bifurcations

Q: the difference and influence between soft bifurcation and hard bifurcation

A: for users, soft forking will not proce new bitcoin currency. They only need to understand the transaction mode and K-line characteristics of bitcoin. They only need a mainstream wallet of bitcoin

hard bifurcation will generate new currencies, and there may be more than one new currency. Once the core code of bitcoin is modified and the core code of bitcoin is reconstructed, there may be a second time for the first time, and btc1 and btc23456789 may all happen. Users will be confused. Which kind of coin would be better for me to trade? What kind of bitcoin do I use to pay for a large circulation range? In short, users with dyschooia will crash. Moreover, users need to download wallets of different hard bifurcated systems, which brings complex operation to save and pay bitcoin

however, correspondingly, the user's right to choose has also increased. You can choose the bitcoin code developed by the development team you like and trust. When the bifurcations of bitcoin are not clear, when the soft bifurcations start to activate and the computing power starts to vote, the best way for users to deal with it is to wait and see. Don't recharge and extract bitcoin in the process of bifurcation

in addition, soft fork will change the settlement mode of bitcoin all nodes, and some small settlement will be confirmed by the third party node, namely settlement channel. The settlement channel may incur part of the service charge. Similar to the role and business model of UnionPay

Bitcoin has opened the era of blockchain 1.0, which is characterized by providing a different way of thinking for value transfer, that is, value transfer no longer depends on centralized institutions such as banks. During this period, as more and more people were familiar with bitcoin, many people began to learn from the idea of bitcoin, so a large number of counterfeit coins appeared

the reason why these counterfeit coins are called "counterfeit coins" is that their source code is similar to that of bitcoin, and there is no substantive breakthrough. They also have the shortcomings of bitcoin, and there is no breakthrough improvement. However, people do not have the problem of bitcoin. Many people in the bitcoin community hope to solve these problems through a variety of technical means, so as to make the bitcoin system perfect

Among them, there is a Russian teenager named vitalik buterin, who is also eager to make up for the shortcomings of bitcoin system as soon as possible

first, you play games in a lively way, while others play games as gatekeepers

when he was 13 years old, he was a typical Internet addict, addicted to world of Warcraft. One day, the game company of world of Warcraft suddenly cancelled his favorite warlock "life siphon" skill. He was very angry and contacted the company many times to restore the skill. However, the game company did not agree

as a result, Butlin began to reflect that in Internet games, players, as participants, are actually very weak. The strong ones are game developers, who are the center of a game. Has the final say that the game player has no say what the developers want to do, and can only choose to accept or leave passively. p>

Butlin realized the disadvantages of centralization through "world of Warcraft", so he began to look for ways to break the centralization. Butlin realized bitcoin from his father, a programmer, and became so interested that he decided to give up the aura of a famous university and drop out of the University of Waterloo to travel around the world to exchange and learn with blockchain enthusiasts all over the world

at that time, bitcoin enthusiasts were going all out to add more functionality to bitcoin and build bitcoin 2.0. But Butlin believes that the establishment of a new programming language is bitcoin's top priority. So, at the age of 19, Butlin wrote a new white paper, which is the rudiment of Ethereum white paper. Butlin mentioned in the white paper

: he hopes to create a variety of applications based on the common programming language, such as social networking, trading, games... These ideas have been strongly echoed by the bitcoin community, and more and more people have joined in the design of Ethereum. Finally, this project was named "Ethereum" by Butlin, because "Ethereum" is a kind of material that has not been confirmed under scientific theory, implying Butlin's expectation for the project

in June 2015, Ethereum officially released

in the next two years, Ethereum's cryptocurrency "Ethereum" became the most popular digital asset after bitcoin. The price of Ethereum increased 85 times in 2017, and more than 20 global top financial institutions and technology companies, such as JPMorgan Chase, Chicago Board of exchange, Microsoft, Intel and Accenture, established the enterprise Ethereum alliance, Butlin has become a blockchain God "V God" from a young boy

2. The great potential of Ethereum to activate blockchain

the emergence of Ethereum has activated the great potential behind blockchain. Why do you say that

the breakthrough of Ethereum is that it not only upgrades the blockchain to an operating system, so that you can develop an application chain on this basis, but also allows you to publish your own tokens in a very simple way

different from bitcoin's preset trading system operation, Ethereum is a programmable blockchain:

Ethereum allows users to create their own operations that meet their needs and have different degrees of complexity. In this sense, Ethereum is a platform. This "platform" has built a relatively complete "system", which is a bit similar to Android and apple. Application developers can develop various applications on this system

this setting makes Ethereum break through the single "monetary function" of bitcoin, and expand the application scenarios of blockchain technology to all aspects. Now, for example, we can do a lot of things through mobile app: paying fees, ordering meals, taking a taxi, shopping and so on. Similarly, developers can develop DAPP (blockchain application) on Ethereum. In the future, you can use DAPP to replace app, paying fees, ordering meals, taking a taxi, shopping and so on. Ethereum gives us these beautiful visions

Thirdly, the consensus mechanism of Ethereum is different from that of bitcoin. As we mentioned earlier, bitcoin decides its bookkeeping rights through the consensus mechanism of pow. Although the security index of pow is high, the energy consumption and cost of mining are huge, and the transaction processing speed is still very slow. Therefore, Ethereum further enriched the technology of bitcoin and proposed a new mining mechanism, namely, proof of interest (POS)

The "proof of equity" proposed by Ethereum is similar to the shareholder mechanism. The more shares people have, the easier they are to obtain the bookkeeping right. It is a system of interest distribution according to the amount and time of holding money. The core logic of POS mechanism is: who holds the currency, who has the control of the network. It should be noted that in the POS mechanism, there is still computing power mining, which needs to solve a mathematical problem. However, the difficulty of the mathematical problem is related to the "age" of the coin holder. The longer the coin holder holds the coin, the easier the difficulty will be, and the greater the probability of digging the coin

Fourthly, the controversial ICO

Ethereum is an open source system, similar to the current Android and apple systems. Developers can develop various applications on it. Most of the ICO projects are based on Ethereum. If developers want to develop blockchain applications (DAPP) on Ethereum, they need to raise certain funds through ICO as operation and maintenance costs

The concept of ICO was very popular in 2017, which was once considered as the main reason for the bull market in 2017

What's the matter with ICO? ICO (initial coin offering) is a way to raise funds for digital currency / blockchain projects. Because the token has market value, it can be converted into legal currency. In this way, it can be used as the development cost of the project. And early participants can get the initial issue of digital currency in return

generally speaking, if a blockchain game company announces: we are going to issue money for private placement (ICO)! If you are particularly optimistic about this project, if you want to participate, you need to buy a certain number of Ethereum and call the wallet address of the blockchain game project party, which is equivalent to that you have participated in the crowdfunding (ICO) of the blockchain game project party. When the currency of this blockchain game company can be traded on the exchange, then they will pay you back according to certain rules

it seems that ICO in blockchain field is similar to IPO in stock field, isn't it? you 're right! In fact, ICO in the blockchain field is very similar to IPO in the stock field. Let's take a look at their general explanation:

IPO refers to an enterprise or company (limited company) selling its shares to the public for the first time

ICO refers to an enterprise or company (mostly blockchain start-ups) selling its token to the public for the first time

however, normally speaking, it is very difficult for an enterprise or company to go through the IPO process. It is very difficult to go through "BP seed round Angel round a round B round C round D pre IPO IPO IPO" without five to eight years. However, ICO in the field of blockchain can only be realized in three to eight months by "white paper - cornerstone investment - Private Placement -

- ICO - Stock Exchange"

This is also the reason why ICO is controversial. At present, many countries define ICO as an illegal act. It is not unreasonable to ban ICO, because at present, the state has no relevant supervision on this aspect, so it is very easy for the project party to illegally raise funds and circle money, which not only causes great losses to investors, but also disrupts the normal financial order

Fifthly, the most important feature of Ethereum is the introction of "smart contract". What does smart contract mean? Smart contract is to define a set of trading rules in the form of code. In our daily life, we usually sign paper contracts, and the implementation of paper contracts needs centralized institutions, that is, the court to supervise. The "smart contract" proposed by Ethereum is to realize decentralized automatic execution through program

the account called "smart contract account" will only be executed according to the code. This technology has a wide range of applications, including insurance, equity, trust and so on. It can be said that this technology can be applied to all activities that need trust

Sixth, the significance of Ethereum: it represents the blockchain 2.0 era. After the glorious period of 2017, now, in the face of bear market, some ICO projects are worried about being tired by the bear market and cash out one after another, leading to a sharp drop in the price of Ethereum. V God, the founder of Ethereum, is also deeply involved in all kinds of rumors. There are often rumors that he is going to quit Ethereum and he is running away

However, Ethereum is indeed a leap forward in blockchain technology, which represents the era of blockchain

2.0. If bitcoin represents the era of blockchain 1.0, it provides new ideas and new methods for value transfer; Then, the blockchain 2.0 era represented by Ethereum makes the commercial application of blockchain possible

V God refers to V God in happy male voice

is elected by the majority of netizens, who hold the power to blackmail other judges

V God should not only have a high popularity, but also directly veto the judgment of one of the judges, directly affect the competition results, and be the VIP of the judges

{rrrrrrr}

extended materials:

the characters represented by V God:

I. in myth,

V God is a Xuanwu people in Beiping. It was born in the autumn of 1987. When he was young, he was gifted. He was often appointed a date by a university in Beijing. He was famous for his expeditions, which can be said to be noisy. Waiting for V God crown, because from the tribe is a graceful station, elegant manner, closed on shy flowers, sunken fish wild goose beauty you

Second, in the game DOTA,

V God has played an immeasurable role in the process of VP winning mym7. God V's gank power is unmatched. Even if God V starts badly. In recent games, he led the team through the suffocating gank to destroy opponents. God V can be competent for any hero, such as the moon arrow, the fearless bounty hunter, and even the witch doctor. There is no doubt that vigoss will continue to rule the DOTA community< Third, in the water king, vshen is a member of the 5th phase of the 3rd unit of arma3 armed assault of saga, a famous domestic game team. Now he has become a regular member and one of the soul figures of the unit

Third, in the economy, vitalik buterin is the founder of Ethereum. Vitalik buterin, inspired by bitcoin, put forward the idea of "next generation cryptocurrency and decentralized application platform", which began to develop through ICO crowdfunding in 2014

at the end of 2013, vitalik buterin, founder of Ethereum, released the first edition white paper of Ethereum and launched the project. From July 24, 2014, Ethereum has carried out a 42 day pre-sale of Ethereum coins

Tencent's search engine is soso

development history of soso:

1. it was officially released and put into operation in March 2006

3. on September 3, 2009, the words "the following results are provided by Google" have been removed from the soso search results page, and the search engine technology developed independently has been used instead

5. in 2013, the word "Tencent effect promotion" has appeared on the soso search results page, and it is stepping into commercialization

< / OL >




misunderstanding of Tencent search engine: Tencent vigorously promotes Sogou, many people mistakenly believe that Sogou belongs to Tencent, but it is not

Sogou search engine is the third generation of interactive search engine strongly built by Sohu company. On September 16, 2013, Tencent injected US $448 million into Sogou and merged its Sogou business and other related assets into Sogou. After the transaction, Tencent immediately acquired 36.5% shares of Sogou after full dilution, and the shareholding ratio of Tencent will increase to about 40% in the near future. This makes Tencent have a higher interest and voice in Sogou, and then use its own channels to promote it

6. Mutual promotion of cryptocurrency development

7.

Rc20 token standard (erc20 token standard) is a standard used to create token through Ethereum. According to the erc20 specification, a smart contract can be written to create a "interchangeable token". It is not mandatory, but following this standard, the token created can interact with many exchanges, wallets, etc. it has now been widely accepted by the instry

erc20 token standard was first proposed by Ethereum developer Fabian vogelsteller in the open source community. Later, Ethereum founder vitalik (known as "V God") wrote the first version of the document, which was called "standardized contract API" at that time_ Contract_ APIs

following erc20 token standard, smart contracts can be written. The token methods it needs to implement include: optional name, symbol, decimals, balance of, transfer, transfer from, approve, and allowance. The event responses it needs to implement include transfer, approve

in addition to erc20, Ethereum also focuses on erc721. Different from erc20, erc721 is a non fungible token standard (NFT)

The general syndromes of

erc20 are interchangeable and homogeneous, while the general syndromes of erc721 are not interchangeable and heterogeneous; Erc20 can be subdivided infinitely, while erc721 can not be subdivided because its minimum unit is 1

in June 2018, erc721 was officially accepted by Ethereum community and became the final standard. The popular cryptokitties followed the erc721 standard

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system

8. Now, blockchain ICO is very popular. Some of them are hyped by the concept of blockchain. However, some of them do operate blockchain projects. For example, blockcdn actually improves the problem of network traffic acceleration through blockchain technology. Last year, v-god, founder of Ethereum, specifically recommended it on twitter.

9. First, the IPFs team is indeed very mysterious in domestic reports
Juan Banet, the founder of the IPFs team, seldom participates in blockchain summit or some offline activities reported in China, and does not have the same high exposure as the founders of Ethereum V God or other project parties. The founders of other projects are often invited to give speeches at regional blockchain summit or serve as platforms for emerging projects. The IPFs team rarely participates in some summit activities held in China, and never provides platform for other projects. According to the official weekly report of ipfs.io, the IPFs team has only organized five community activities in 2018, which are for community enthusiasts, and other meetings are for developers who need to be invited
Second, the filecoin project has not been launched for a long time, and the progress of the project is not very dynamic
according to the blog information on the official website of filecoin, filecoin was crowdfunding on the coinlist platform (a financing platform dedicated to providing initial token issuance (ICO) for certified investors and high-quality blockchain projects) on August 12, 2017. Tens of thousands of investments and excessive traffic also caused some twists and turns in the crowdfunding process of the platform. Since then, a blog notice was sent on September 13, 17, raising more than 205 million dollars in investment. By 2018, the blog has been updated four times, one is a quarterly report on January 1, and the last three are quarterly reports and Q & A in the second half of the year. Compared with other 17 years of crowdfunding projects such as EOS, quantum qtum and omg, filecoin can almost be said to be very low-key and stable
thirdly, there are too many manufacturers selling storage mining machines under the name of IPFs in the market, so it is inevitable that there are black heart manufacturers
e to the rich experience of bitcoin and Ethereum's early miners, many investors who missed the filecoin crowdfunding ICO can think of an investment opportunity to dig filecoin. So a lot of people smell business opportunities in it. For a while, IPFs mining machine manufacturers of various brands have sprung up, but filecoin has not been online for a long time. What should we do? As a result, with the technology vision of IPFs and all kinds of false propaganda, there are generally three types of black heart manufacturers:
the first is to take the equipment with a cost of 300 and sell it at a price of 1000 yuan or even 10000 yuan. Such equipment is often small boxes that look like routers. According to the feedback from the professional team participating in the test of filecoin development network, such a small box can't find filecoin
the second kind of scam is to take the white paper of filecoin, delete and modify it, turn it into a new project, and then sell the exclusive mining machine developed by ourselves. This kind of project side, while selling high priced mining machines, takes out part of the profits and manages the market value of the excavated tokens in the exchange. It can be said that it is a double harvest, which makes it impossible to prevent
the third kind of scam, with the name of cloud computing power and node hosting, has no entity. It mainly sells at a high price through the bonus mode of more than three levels, and over promises revenue and online time. Such a brand can not be found on the Internet, not to mention on the official website
Fourth, the filecoin project has not been launched yet, but the exchange can't wait to launch the futures trading
after learning about the filecoin project, some investors decided to go to the exchange to buy some fils and wait for the currency price of the project to rise. It should be noted that the fils currently traded in the exchange are futures. First of all, the fil purchased here can't be circulated, and it can't be extracted from the personal wallet. It can only be stored in the exchange. Secondly, there are fil6, fil12 and fil36 in the current futures trading, which respectively represent the delivery of filecoin six months, 12 months and 36 months after it goes online. In other words, after the main network goes online, it still needs to wait several months to get the real fil, which still has certain risks
fifthly, many Paolu public chains have written IPFs as their underlying technology into the white paper, which has led many investors who have lost all their money to talk about "IPFs"
among them, there are two projects with relatively high exposure. The first one is filecash coin, or FCC for short. It claims to be the first public storage chain in Hong Kong based on IPFs technology. Its founder, Mr. coin, once made the headlines for throwing paper money on the streets of Hong Kong. At present, the "master coin" has been arrested, and the FCC's official website has been unable to open, and the platform trading has disappointed investors because of the multiple rounds of currency price diving.
