Ethereum annual Developer Conference
recently, the identity of Satoshi Nakamoto, the father of bitcoin, was accidentally exposed, which made bitcoin, which had graally faded out of the public's view, hot again. However, Craig, an Australian businessman with low-key and simple daily behavior, is still in the market; It took only five days for Craig Wright to admit that he had no courage to give up and prove that he was Nakamoto
not surprisingly, the mystery of "Nakamoto Tsung" will continue
"the twists and turns of Zhongben Cong's identity have not brought significant impact on the bitcoin market," Li Qiyuan, President of bitcoin China (BTCC), said in an interview with the first Financial Daily yesterday (May 9). As an innovative thing, bitcoin has been able to survive and grow steadily in the past few years, marking a kind of success. Liu Shengjun, executive vice president of China Europe Lujiazui Institute of international finance, is worried about the development prospect of bitcoin. "At present, no government is willing to give up its management power and accept bitcoin to replace legal tender."< On November 1, 2008, Nakamoto published a research report in a secret cryptography discussion group, in which the concept of bitcoin was first proposed. In 2009, the world's first bitcoin algorithm software appeared. In just four years after that, the price of bitcoin increased by hundreds or even thousands of times, which eclipsed other investment targets
as the creator of bitcoin, "Nakamoto Tsung" not only grasps the most core technology, but also increases people's curiosity and speculation about his real identity because of its huge wealth brought by about 1 million bitcoins (the current price of one bitcoin is about 2970 yuan)< On May 2, Wright publicly told several major overseas media that he was the so-called "Nakamoto Tsung", the founder of bitcoin, which aroused heated discussion in the market<
(the price trend of bitcoin in the past year)
Wright, 46, is a computer scientist and an entrepreneur. When he introced himself at the 2015 bitcoin investor conference, he said that he was a scholar, engaged in business research, and had a doctor of law and a master's degree in statistics
according to foreign mainstream media, Wright confirmed his identity as "Nakamoto Tsung" from a technical point of view by using the bitcoin owned by the founder of bitcoin. Wright also said publicly that it was not easy to make a decision to disclose his identity, and the reason for his clarification was his love and concern for his work, which he "hoped to eliminate the false legends and worries surrounding bitcoin"
as the Internet world continues to argue about Wright's real identity, the plot takes a major turn< On May 6, Wright suddenly published an open letter entitled "I'm sorry", saying that he "has no courage" to continue to prove his identity as "Nakamoto Tsung"
"I believed that I could end the years of hiding and hiding. However, with the events of the past week fermenting, I was going to publish the evidence that I had the initial block, but I couldn't stand it. I don't have the courage. I can't do it. " Wright said<
Wright once said in his public identity that he did not want money, nor did he want to be famous, nor did he want to be worshipped, but only wanted to be alone. Li Qiyuan told China Business Daily that if he really wanted to live his own life, why did he suddenly choose to expose his identity
obviously, the emergence of Wright has not completely ended the mystery of "Nakamoto" and investors are more concerned about the impact of "Nakamoto" on the price of bitcoin
Gong Ming, the founder of blockchain pencil, told the first financial daily that the identity of "Zhongben cong" will not have a substantial impact on the market, but is more symbolic. Unless "Nakamoto Tsung" sells a lot of bitcoin, it will not have an impact on the price of bitcoin. "From 2009 to now," Nakamoto Tsung "is not a person who has a strong desire for money and will not buy or sell bitcoin because of the high or low value of the currency."< Recently, Zug, a small Swiss town, announced that from July 1 this year, buyers will be allowed to pay for its public services with bitcoin as the payment method. Although there are still great limitations in the scope and amount of this payment method, the small progress is enough to cheer bitcoin's staunch admirers
from the beginning, virtual goods can only be purchased on the Internet, to now, bitcoin can be converted into multi-national currencies, and there are many twists and turns along the way
in February 2014, Mt. GOx, the world's largest bitcoin trading platform at that time, said that bitcoin was stolen e to large-scale hacker attacks, with a total loss of $470 million, and the platform declared bankruptcy. Affected by this, the price of bitcoin plummeted from more than $600 to $102 in just a few seconds, a drop of 83%
in January 2015, bitstamp, one of the most reliable bitcoin trading platforms in the world, was attacked by hackers, resulting in the theft of at least US $5 million of bitcoin, causing panic among some cryptocurrency holders. The openness and security of bitcoin cause instry concern. When the negative news came out, bitcoin was finally recognized by the regulatory authorities
in September 2015, the US Commodity Futures Trading Commission (CFTC) confirmed for the first time that bitcoin and other virtual currencies are defined as commodities, which means that bitcoin is classified as commodities like gold and oil, and trading behavior will comply with all commodity derivatives market rules; In October of the same year, the European Court of justice formally ruled that bitcoin and other virtual currencies in Europe should be exempt from VAT just like traditional currencies. Because according to the relevant provisions of the EU, "currencies, bank bills and coins used as legal tender" do not need to pay VAT. Bitcoin has taken a solid step towards legalization
nevertheless, the market is still worried about whether bitcoin, which reached a historical peak of more than 8000 yuan in 2013, can return to its former glory
at present, the price of bitcoin is hovering around 2900 yuan, which is much more stable than the previous ups and downs, and the trading volume of bitcoin has also dropped significantly
"I don't think bitcoin has changed from hot to cold. Compared with the sharp rise and overheating in 2013, I think it is now the normal price of bitcoin. In 2013, bitcoin rose from tens of dollars in January to thousands of dollars in less than a year, overdrawing the later increase, so it has been falling back after 2013." Gong Ming told the first financial daily
how much is bitcoin worth? It is estimated that bitcoin players, exchanges, mining machine manufacturers and even bitcoin creators can not give an accurate answer
although the value of bitcoin cannot be determined, one thing is certain that the number of bitcoins is certain. Because the "issuance" of bitcoin depends on complex calculation, it is essentially different from the "printing" mode of traditional currency issuance. The total amount of bitcoin graally increases according to the design predetermined rate, and the increase rate graally slows down, and finally reaches the limit of 21 million in 2140. The instry estimates that the total amount has reached 15.5 million
Li Qiyuan believes that the limited number of bitcoin is in sharp contrast to the inflation and the decline in the purchasing power of fiat money caused by the massive printing of money by central banks“ The goal of bitcoin is not to replace the existing currency, but to become a universal digital asset in the world and provide convenience for people's lives. "
it is generally expected that with the departure of short-term speculators, the continuous development of bitcoin related applications and the improvement of infrastructure, the digital currency represented by bitcoin will be in a benign development stage
in addition to bitcoin, there are also outstanding digital currencies such as lightcoin, Ethereum, dogcoin and Ruitai coin.
Ethereum Community Foundation (ECF) is a non-profit organization. Its original idea was to give community projects a bonus to support incubation of early projects and research. Then in 2018, omisego, Golem, status, maker, Web3 (Polkadot), cosmos and ef (Ethereum Fund) were set up in Tokyo as consultants
ECF 2.0 is the upgrade of ECF, which has two core goals:
< UL >
coordinate community relations through various harmonious ways, such as bonus, strategic and business support, and community activities
in order to become an open capital network, ECF emphasizes its initial vision, which is to form a network with various funds to realize the support and contribution to the community
In addition, ECF 2.0 upgrade will not only support non-profit infrastructure projects, ecation programs, instrial community activities, but also support application and tool development, and even commercial projectsDigital assets and digital currency are not the same thing
Digital assets refer to the non monetary assets owned or controlled by enterprises or indivials in the form of electronic data and held in daily activities for sale or in the process of proction. The emergence of digital assets benefits from office automation, digital assets rely on the development of electronic payment system, its prospects are predictable2. Digital currency
digital currency refers to the digitization of currency. Digitization doesn't mean scanning. This is just like digital signature. Digital signature does not mean scanning your signature into a digital image, or using the touchpad to obtain the signature, let alone your signature
digital currency is often mistaken for virtual currency. But virtual currency refers to non real currency. For example, when you play "Three Kingdoms" (game) or "grand Voyage", you have money, and that money is virtual. Of course, the virtual money will also have its real value
for example, if you buy her / his account from another player, you can get all the virtual assets of that player, and then it will be much easier for you to continue playing. Virtual money is not necessarily digital. For example, children play games with pebbles as virtual currency
extended data
characteristics of digital assets:
1. High price. Because these application software with special purpose is specially developed for a specific work, its cost is relatively high, and its price is not lower than the price of fixed assets of factory buildings
(2) strong attachment. Application software must be supported by computer hardware and system software in order to play its role3. Strong interaction. Even the simplest application software also has some interactive functions, such as the error prompt to the operator, which is the most basic advantage of IT instry procts
The quantity is infinite. Digital assets as assets are scarce (because not all enterprises or indivials can create digital assets), but its supply can be unlimited. However, tangible assets are always limited e to the limitation of property and storage space Cost decreasing. The proction cost of tangible assets is positively proportional to the proction quantity References:

what is MLM coin? MLM coin is a virtual currency used in MLM activities. Like other MLM activities, it usually encourages members to earn returns by pulling people to buy MLM coins under the slogan of "get rich quickly". Of course, the final result is that many investors have been cheated out of their money. Speaking of this, many investors want to ask, what are the MLM coins in the market? Only by knowing which are MLM coins can we avoid stepping on thunder again. Next, we will summarize the list of MLM coins in 2020<

how to distinguish MLM currency
1
virtual currency does not rely on specific monetary institutions to issue, it is based on a specific algorithm, generated through a large number of calculations, is a decentralized way of issuing. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head
2
virtual currency is a kind of sporadic transaction formed spontaneously in the market. After the scale is formed, the third party graally establishes an exchange to complete the transaction. The MLM currency is issued by an institution and traded on its own platform
3
virtual currency itself is an open source program, which is maintained in GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency
4. Whether to give the source code link
the general decentralized digital currency will give the link of the source code in the prominent position of the official website, so as to show the operation mechanism of the system openly and transparently. What MLM currency focuses on is the transaction process of recharge purchase, not to mention its operation mechanism, and even the website does not have the link address of the source code
5. Whether the official website starts with HTTPS
in general, the addresses of the official website and trading website of decentralized digital currency begin with HTTPS. The purpose of this kind of website is to protect users' data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS
what is MLM? Through the above introction, I believe you already know something about MLM coin. The editor of currency circle reminds investors that if someone tells you by phone or flyer that there is a virtual currency with stable profit and no loss, or that the interest is high and the principal is guaranteed, you must be careful. According to the identification method provided in this paper, you should not easily believe it. You can go to the regular and reliable exchanges to see if there is also a change in currency, Don't trust a small exchange at will, because such an exchange may be a liar. In a word, investment is risky and investment should be cautious. If you want to know more about related issues, you can pay attention to the follow-up reports of the coin circle
what is Shanzhai coin? What is Shanzhai coin? What is Shanzhai coin? At present, there are numerous virtual currencies on the market. Among them, some are short-lived, some are popular and sought after. In fact, in addition to the well-known bitcoin, there are many virtual currencies, of which at least 11 are called Shanzhai currency. Of course, what is Shanzhai currency? At present, there are numerous virtual currencies on the market. Among them, some are short-lived, some are popular and sought after. In fact, in addition to the well-known bitcoin, there are many virtual currencies, of which at least 11 are called Shanzhai currency. Of course, Shanzhai currency does not mean counterfeit currency or pirated currency, The Shanzhai coin mentioned in this paper is a new virtual currency proced by many innovations e to the deficiency of pointer bitcoin. Next, the coin circle editor will explain in detail what Shanzhai coin is? Hope that through this article, investors can understand what is Shanzhai currency
what is Shanzhai coin
Shanzhai coin is a kind of blockchain asset that uses bitcoin code as a template to modify its underlying technology blockchain, among which technical innovation or improvement is also called competitive currency. Because of the open source of bitcoin code, the cost of bitcoin plagiarism is very low. Even if you just the bitcoin code and modify some parameters, you can generate a new blockchain. At present, there are many counterfeit coins. Most Shanzhai coins are not recognized by the market e to the weak technical strength of the founders, lack of technical maintenance, lack of market promotion and other reasons. Only a few teams with strong technical strength and innovation ability can develop excellent competitive currency which is recognized by the market and has investment value. We are familiar with the competitive currency such as Leyte currency
how to choose Shanzhai coin< Market value is the best screening machine
reference market value is the most stupid method, which has great limitations and is a compromise. Bitcoin can be held without a brain, but the water of Shanzhai coin is very deep, and it takes a lot of brain energy to screen. For those who know little about blockchain, they have no ability to screen out potential small currencies. Some people have summarized that the top 10 currencies change their posts in turn every year, except bitcoin, which is rubbish. In fact, compared with the top 50 currencies over the years, you will find that many of them are relatively stable. Projects with strong communities and supportive scenarios are hard to disappear
therefore, for ordinary investors, the market value is a very good reference index, because the capital market votes with its feet, and there must be a reason for the high market value. Those old coins that can survive are stable at the top 50. They have more or less capital to support, so they can choose Shanzhai coins with large market value or leaders in different fields
2. To confirm whether the Shanzhai coin can survive the bull market
first of all, we should realize that not all the coins can survive the bull market successfully. Before the Shanzhai coin bull market, bitcoin market will be completely suppressed, and if it falls sharply, many Shanzhai coins will be drained to death. For example, 17 year old Daniel, many coins will die before the bull market, For example, at present, many projects and exchanges are beginning to be unbearable. For investors, it's not easy to survive the bear market, and as a result, they hit a return to zero coin before the bull market. It's hopeless, so make sure that your coin can last to the bull market
many exchanges have taken off some counterfeit coins, and these coins have only been put on several exchanges, or even only one platform. Once they are taken off the shelves, they are basically sentenced to death. Therefore, we can refer to the fact that counterfeit coins have been put on several exchanges, some of which are head exchanges. Besides, look at whether their official website, official account, micro-blog, twitter, GitHub have updated projects, and if there are more than a few months of parking, they must stay away from the project.
in addition, it also depends on whether the project will progress and develop. You can check the roadmap on the official website to see whether the progress in reality has kept up with the expected goal of the roadmap, and whether there are any new plans in the next few years
3. New technology, new story
many bitcoin fans have missed eth perfectly. In their eyes, except bitcoin, everything else is shit. Maybe Ethereum will return to zero in the future, but they have missed a whole prosperous period of Ethereum. Ethereum has introced the smart contract, which brings more possibilities and new stories to the blockchain. Although Ethereum is a good tool for ic0 to make money, who wants to miss the wealth effect brought by its technological innovation
the explosive power brought by new technology is very strong. Ethereum is taking this opportunity to directly cut into the second place. At the same time, it also shows that the technology changes very fast. If there is no technical breakthrough in the current projects, they may be on the verge of death in a few years, because they need to leave room for new technology coins and new stories. EOS is just an evolutionary version of eth, which obviously cuts leeks in a bull market
of course, it's not easy to catch a fast car like eth or iota, and it's more gambling. It's like looking for a needle in a haystack to catch the next round of killer projects. Even if you catch it, it's hard to grasp it. If you think you've caught the killer projects in the next round of blockchain instry, look at Zhihu's reply of 11 year old clip, buy it, put it in your wallet, and then forget it
what is Shanzhai coin? Through the above introction, I believe you have some understanding of Shanzhai coin and how to choose Shanzhai coin. The coin circle editor should remind investors that when investing in counterfeit currencies, they should not invest all the funds. At the same time, they should also remember to stop losses or profits in time. The most important thing is that if they don't have too much energy, investors will return to mainstream currencies. Of course, no matter what currency they choose, the most important thing is the choice of the exchange. This can avoid the risk of the exchange running away.
According to foreign media reports, although the price of bitcoin has dropped sharply this year, the cryptocurrency conference is still a major event
This week, coindesk, a well-known bitcoin news website, will hold a three-day bitcoin conference in New York City with a ticket price of about $2000. It is expected that 4000 people will attend the meeting, which is a lot more than last year's 2700 people. As a result, ticket revenue for the conference will be at least $8 millionwithin a few days of the bitcoin conference in New York, there are 20 other conferences held at the same time, and the ticket price of these conferences is also very high. Three years ago, the consensus conference was first held, and only 400 people attended. Now, the conference has become the main feature of blockchain week NYC
before and after the consensus meeting held in May last year, the price of bitcoin soared to about $2000. Of course, this is also the result of the first tokensummit summit and ethereal summit
since then, the price of bitcoin has skyrocketed, successfully attracted the interest of Wall Street, and exceeded $10000 for the first time after the consensis invest meeting held in November. In December, the price of bitcoin peaked at more than $19000. But since then, its price has fallen by more than half
strong speaker lineup
this year's speaker lineup shows that the cryptocurrency instry has taken an important step towards the mainstream direction. Jack Dorsey, co-founder of microblogging site twitter, is e to speak at the consensus conference on Wednesday. Square, his mobile payment company, also launched bitcoin trading this year. Other members of the meeting's expert group include government officials and heads of start-ups
"the consensus conference is very famous. If you give a speech at the conference, it means that you are also very famous." Said Michael oved, co-founder of airswap, the cryptocurrency exchange. He is also the organizer of the fluidity blockchain conference held last Thursday
he said that he deliberately lowered the ticket price of his fluidity conference to $150-250. Because he thinks it's a "good opportunity for us to share what we're studying.". About 700 people attended the fluidity conference, and ticket sales reached about $140000, oweed said
"ironically, the organizers charge a lot, but they never pay the speakers. These speakers are the people who are most concerned about the development of the blockchain community and are most eager to share new developments. " She tweeted on April 28
she will give speeches at ethereal summit and consensus meeting this week“ Neither of these meetings paid me for my speech. " She said. She added, "live online is a great way for the public to watch the content of the conference."
"too many meetings, it's crazy"
all kinds of meetings are very powerful and lively, but we don't know whether they finally help start-ups, especially those with imperfect management
"there are too many meetings now. It's crazy." "In the San Francisco Bay area alone, there's a weekly meeting on blockchain," oweed said. It's easy for us to be distracted by these meetings. "
however, some people are convinced that these meetings will eventually be the catalyst for the recovery of bitcoin prices
"after the previous consensus meetings, the price of bitcoin will rise. This fact strongly supports our view that the price of bitcoin has hit the bottom this year. " "During every meeting, the price of bitcoin goes up 10-70%," Tom Lee, co-founder of fundstrat global research, a market research firm, said in a research briefing on May 7
he added, "considering the significant increase in the number of participants, we believe that the price of all cryptocurrencies will increase similarly."
