The first Ethereum Developer Conference
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 projectsblockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention
on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019
extended data:
Application of blockchain Finance:
since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain Technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency
standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency
in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016
the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology
Three questions blockchain (economic hot spot)
recently, news about bitcoin is very eye-catching, and blockchain is on fire. In the capital market, the rise and fall of various blockchain concept stocks is like a roller coaster. It can be seen from the sensitive capital market that the blockchain is on the way and is highly concerned by all parties
"blockchain technology is essentially a kind of database technology, specifically a kind of ledger technology. The account book records the asset changes and transactions of one or more accounts. In fact, it is a kind of database with the simplest structure. The daily accounts we usually record in the small account book and the statements sent by the bank are typical account books. " Wang Jun, chief researcher of Tencent Financial technology think tank, said that security is a major feature of blockchain technology, which is mainly reflected in two aspects: one is the distributed storage architecture. The more nodes there are, the higher the security of data storage is; The other is the ingenious design of tamper proof and decentralization, which makes it difficult for anyone to modify data without following the rules
take the online shopping transaction as an example, the traditional mode is that the buyer purchases the goods, and then sends the money to the intermediary platform of the third-party payment institution. After the seller delivers the goods and the buyer confirms the receipt, the buyer informs the payment institution to send the money to the seller's account. The transaction mode supported by blockchain technology is different. Buyers and sellers can trade directly without any intermediary platform. After the transaction between the buyer and the seller, the system publishes the transaction information in the form of broadcast, and all hosts receiving the information record the transaction after confirming that the information is correct, which means that all hosts have done data backup for the transaction. Even if a machine has problems in the future, it will not affect the data recording, because there are countless machines as backup
when it comes to blockchain, many people associate it with bitcoin, and many even equate blockchain with bitcoin. He Fei said that bitcoin is a way of presenting blockchain, but blockchain is not the same as bitcoin. Blockchain is the underlying technology and infrastructure of bitcoin, and bitcoin is a successful application of blockchain, but it does not mean that blockchain can only be applied to bitcoin
What is the use ofblockchain
can solve the pain points and difficulties in many fields such as finance, public welfare, supervision, anti-counterfeiting, but there are many applicable conditions
financial service is the first application field of blockchain technology. The application of blockchain technology can solve the pain points in payment, asset management, securities and other fields
taking the payment field as an example, the cost of reconciliation, clearing and settlement among financial institutions, especially cross-border financial institutions, is high, involving many manual processes, which not only leads to high costs for users and financial institutions' back-end business, but also makes it difficult to develop micro payment business. The application of blockchain technology helps to rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing efficiency of payment business. In addition, the cost and efficiency advantages brought by blockchain technology in the field of payment enable financial institutions to better handle the small cross-border payment which was considered unrealistic e to high cost in the past, and contribute to the realization of Inclusive Finance
for example, in order to solve the problem of high reconciliation cost among financial institutions, in August 2016, Weizhong bank and Shanghai Huarui Bank launched the inter agency reconciliation platform of micro loan, which is also the first application scenario of banking alliance chain running in the proction environment in China. Zhang Kaixiang, chief architect of Weizhong bank's blockchain, believes that the high cost problem that the traditional "batch file reconciliation" model has failed to solve for a long time is exactly where blockchain technology can be used. Subsequently, Bank of Luoyang and Bank of Changsha have also been connected to the inter agency reconciliation platform. Through the blockchain technology, the inter agency reconciliation process in the micro loan business has been optimized, achieving the goals of quasi real-time reconciliation, improving operation efficiency and recing operation cost. Up to now, the platform has been running stably for more than one year, with zero failure, and the number of real transactions recorded has reached tens of millions
in the field of public welfare, blockchain technology is also promising. The first application scenario of ant financial services involving blockchain is public welfare, which helps a group of hearing-impaired children get a donation, and then uses blockchain technology to promote public welfare to be more open and transparent. Hu Danqing, senior proct expert of ant financial services technology laboratory, said: "the blockchain public welfare platform is like a post office dedicated to mailing funds on the Internet. Every sum of money donated by users will be packaged into a package, which will be delivered through the blockchain platform. Every node we pass through will be stamped with a postmark and finally delivered to the recipient. This can ensure that every sum of money donated by users is transparent, traceable and difficult to tamper with. "
blockchain technology can be used to crack down on counterfeit goods. Hu Danqing introced that ant financial services has applied blockchain technology to the traceability of authentic procts. At present, some seafood procts from Australia and New Zealand, such as milk powder, are swept away with Alipay, so they can know if they are genuine procts. Different from previous businesses' self input of commodity information, blockchain allows multiple "bookkeepers" to complete bookkeeping fairly, independently and non repudiately. "
for financial supervision, blockchain technology can also play a role. According to the white paper of FISCO bcos, the underlying platform of financial blockchain, issued by the financial blockchain cooperation alliance (Shenzhen) in 2017, blockchain provides consistent and easy to audit data for financial regulators. Through the data analysis of inter agency blockchain, it can supervise financial business faster and more accurately than the traditional audit process. For example, in the anti money laundering scenario, the balance and transaction records of each account are traceable, and any link of any transaction will not be separated from the regulatory line of sight, which will greatly improve the anti money laundering efforts
some people in the instry believe that blockchain 1.0 is mainly aimed at digital currency; Blockchain 2.0 aims at smart contracts and can be applied in financial markets; Blockchain 3.0 will apply to more scenarios, and even create a "blockchain era"
He Fei believes that blockchain can indeed solve the pain points and difficulties in many fields, but blockchain is not omnipotent and has many applicable conditions
for example, the decentralization of blockchain technology is suitable for multi-party participation scenarios, and if it is only unilateral or bilateral participation, the value is not great. Due to the need for each node to check, blockchain technology is not suitable for those high-frequency trading activities
for another example, blockchain emphasizes openness and transparency, which is not suitable for scenarios with high data privacy requirements
will blockchain become a new outlet
technology is not yet mature enough. We must be alert to the concept of speculation. In particular, we should distinguish between technological innovation or fund-raising innovation. We can not block the chain chain concept of
block chain so that we will not become a "Internet plus". p>
in recent years, the development ecology of blockchain has been graally improved and enriched. Instry insiders believe that with national policy support, extensive attention and financial support, blockchain technology can achieve graal and stable progress. Although the prospect of blockchain technology is broad, we should also keep an ordinary mind
"despite the current blockchain craze, we still believe that it is still in a very early stage." Hu Danqing said that at present, there is a virtual heat in the concept of blockchain. Instead of using technology to solve practical problems, it is hot to raise money and speculate on valuation. In particular, most of the so-called ICO (initial token issuance) that are hot are innovation of fund-raising tools, which has nothing to do with technological innovation
blockchain technology can indeed create great value, but some risks can not be ignored
"blockchain technology is not very mature, and its application scenarios are relatively limited, so we should be more alert to the concept of capital market speculation." He Fei said that behind the blockchain boom, there will inevitably be some companies that want to speculate. They do not really carry out business, but just try to make a profit in the capital market. They should be careful to prevent the emergence of "bad money drives out good money", which will lead to the withdrawal of institutions that really want to carry out business from the market and affect the application of blockchain technology
Hu Danqing suggested that for the current blockchain craze, regulatory authorities should be more active in intervening, distinguish between technological innovation and fund-raising innovation, encourage government organizations, credible experts and instry participants to help the public identify, comprehensively curb fund-raising innovation in the name of blockchain, and let the actual controller of ICO bear responsibility for fund-raising behavior“ The basis for judging whether it is technological innovation or fund-raising innovation is actually very clear, that is, whether it starts with trust and whether it creates practical value by solving the trust problem. "
in order to better promote and use blockchain technology in the future, we need to continue to improve the infrastructure and strengthen the formulation of relevant laws and policies
Wang Jun believes that there is still room for optimization and improvement of core technologies of blockchain such as consensus algorithm; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. At present, the mainstream blockchain technology platforms are originated in foreign countries. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. Enterprises with blockchain application scenarios should actively embrace new things and scientifically evaluate the demand for blockchain, instead of blockchain for the sake of blockchainHe Fei believes that the government can issue relevant policies to guide the enterprises who are interested in the R & D and application of blockchain technology, and at the same time, clarify some suitable application scenarios of blockchain and areas encouraged by the state
the white paper 2016 on the development of China's blockchain technology and application suggests that government departments at all levels should learn from the advanced practices of developed countries and regions and, in combination with the development of China's blockchain technology and application, timely issue support policies for blockchain technology and instrial development, focusing on supporting key technology tackling, major demonstration projects, the construction of "innovation and entrepreneurship" platform, and the development of China's blockchain technology and application System solution development and public service platform construction. At the same time, it is suggested that domestic key enterprises, scientific research institutions, universities and user units should strengthen cooperation to speed up the research of core key technologies such as consensus mechanism, programmable contract, distributed storage and digital signature
can bring money to the enterprise will become the outlet
Some time ago, a picture of Chinese aunts appearing on the scene of the blockchain conference became popular on the Internet. For a while, it caused a heated discussion. Netizens said one after another: "aunts have been targeted by the blockchain." In fact, since a few years ago, when the concept of blockchain came out, there have been some illegal elements carrying out pyramid selling activities in the name of blockchain, which has become one of the latest varieties of pyramid selling. In fact, with the development of blockchain, all kinds of virtual currencies emerge as the times require. Most of them are scams. In the name of "virtual currency" and "blockchain", swindlers carry out scams. This is mainly to make use of the psychology that investors do not understand virtual currency and blockchain, but want to catch up with the upsurge of virtual currency investment. This kind of scam seems complicated, but it is also very simple. However, once it is cheated, it is difficult to recover the investment
in a word, blockchain technology is not a fraud, but is used by swindlers to cheat investors by using information asymmetry
when many people are doing blockchain, they usually register a foundation to run with ordinary companies. Compared with Singapore foundation, what are the common problems when they register a Singapore foundation to do blockchain, Below, we will sort out and share some of our customers' concerns with you
1. Does the registration fee include the cost of the white paper
A: No, the legal adviser is a personalized business, and the fee depends on the project. The legal adviser can provide services in the whole process. Including the revision of the legal provisions of the white paper, and the issue of professional legal opinions on relevant laws and regulations such as the non securities nature of the token. ICO is the legal consultation in the process of issuing currency
2. About the Singapore foundation. Why should there be a company to operate and what is the relationship with the foundation? Why not register a company directly for ICO and exchange docking
A: the foundation is a public welfare organization and a public sector. It is more concive to attract investment and technology development to use the foundation to issue blockchain. It can also be directly ICO through ordinary companies. It depends on how customers want to operate
3. Isn't ICO a way to raise funds?
A: Yes. Participate in the crowdfunding of the project with the existing real value currency, and exchange for the new cryptocurrency issued by the project. The advantage of fundraisers is that they get the funds to carry out the project, while the participants want the project to be successful. In this way, the newly issued cryptocurrency in their hands is likely to appreciate and arbitrage. The so-called ICO means that investors use bitcoin and other ready-made virtual digital currencies to exchange for new tokens issued by ICO projects. Because there are few new currency owners and the price fluctuates greatly, the selling price on the exchange is likely to be much higher than the issuing price. The sponsors of ICO project use the traditional digital currency to exchange RMB and other legal currencies in the exchange, and then put them into the designated technical projects
4. Why not raise funds through common channels
A: the threshold of common channels is low, and there is no regulatory department. The risk is high
5. How to set up an exchange
A: you can choose an exchange according to your own situation. Generally, you should have strong experience in digital asset security management. There are many platforms
6. Why do you need to make a legal opinion
according to Singapore's financial law and securities law, if a virtual currency with securities nature needs to apply for a special financial license, so it needs to prove that the project does not contain securities nature, it needs a lawyer to issue a legal opinion on the non securitization of token and a legal opinion on compliance of white paper to prove the legality and compliance of the project, both of which are required by most customers
7. How can a registered Singapore foundation open an account in a bank
first of all, there is no need to open an account for a registered public non-profit foundation, and it is useless to open an account because the nature of the foundation itself is non-profit. When it comes to the next year's audit, can't it explain the income and expenditure of the bank account with the monetary authority? Second, the bank has a choice of customers. If the bank is told to do blockchain, the bank will not accept opening an account; Third, whether it's private placement or public offering, all the money raised are virtual currencies like Ethereum bitcoin. Ordinary bank accounts can't accept these currencies, so I don't recommend opening an account in a bank.
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."
Vicat China has internally confirmed that Vicat is "direct selling", but it has not obtained the domestic license. In the list of 61 direct selling enterprises published by the Ministry of Commerce, the reporter did not find the name of Vicat
bitcoin and other virtual currencies are open source programs, and the parameters and methods of their total amount limit are displayed in the open source code, so as to show the operation mechanism of the currency system openly and transparently. However, Vicat does not disclose its source code, which in itself violates the basic principles of virtual currency. " In addition, bitcoin and other virtual currencies are scattered transactions spontaneously formed in the market, and after the scale is formed, the third party graally establishes an exchange to complete the transaction. The Vicat is issued by itself and traded on its own platform. The so-called cooperation with the bank is nothing. Vicat currency, which has problems in basic properties, has high investment risk, so investors need to be cautious Netease News)
in the coin circle, bitcoin home and many mass media have also exposed the pyramid scheme of Vicat under the guise of bitcoin
economists point out that Vicat is a virtual currency with the nature of multi-level pyramid selling, and its investment risk is extremely high, so participants should be cautious China business website)
