a brief history of etheric Classics (etc)

etheric classics began with an unfortunate event

in May 2016, the decentralized autonomous organization (DAO) held a token sale with the goal of establishing a blockchain based venture capital to fund future decentralized applications (dapps) in the Ethereum ecosystem

basically, Dao is a complex smart contract that operates in a decentralized way - computer code that automatically performs tasks between multiple parties when conditions are met

despite its ambitious goals and successful token sales, Dao's code has a major vulnerability that allows attackers to steal eth from decentralized organizations

the attacker took advantage of this vulnerability in June 2016, triggering the infamous Dao hacking event, and maliciously stole eth worth about US $50 million

there is no doubt that Dao hacking has shocked Ethereum community and made eth price drop from $20 to $13

after the Dao hacking, the Ethereum community has to choose from three options

< UL >
  • do nothing and try to bear the consequences of the attack

  • start soft bifurcation to recover funds

  • deploy a hard fork to recover the lost eth

  • both soft and hard bifurcations are significant network upgrades. However, soft fork allows users who are not upgraded to communicate with upgraded users, while hard fork is not backward compatible with previous versions

    as developers realize that deploying soft forks will expose the network to distributed denial of service (DDoS) attacks, Ethereum community decides to initiate hard forks to recover the funds lost in Dao hacking attacks

    although this scheme is supported by most people, a small number of people in Ethereum community oppose it. They think that "code is the law" and blockchain network should be unchangeable

    the failure of both sides to reach an agreement on the solution eventually led to the fragmentation of Ethereum blockchain

    those who tried to recover the lost eth chose the hard fork and opened the Ethereum (ETH) blockchain as we know it today, while another group stayed on the original Ethereum classic (etc) chain

    what problems does ethereal classic solve

    Ethernet classic (etc) is a blockchain platform that allows developers to deploy smart contracts and dapps

    although this function is the same as Ethereum (ETH), etc blockchain has two main differences

    first of all, Ethereum classic community opposes tampering with distributed ledger and supports the view that "blockchain network cannot and should not be modified"

    secondly, although there is no rigid upper limit on the total supply of eth, it is allowed to create 230 million etc at most by adopting the monetary policy of constant supply

    as a bonus item, ethereal classic launched Atlantis hard bifurcation last year to increase the interaction with Ethereum and improve the privacy protection of transactions through ZK snarks

    the trading platforms recommended by ethereal classic etc are: Fire coin, okex, AAX, etc

    2.

    as of August 23, 2019, Ethereum price: the highest price in 24 hours is ¥ 1922.07 ≈ 0.0365btc, the lowest price in 24 hours is ¥ 1876.36 ≈ 0.0356btc, the highest price in history is ¥ 10047.07 ≈ 0.1906btc, and the lowest price in history is ¥ 2.95 ≈ 0.0001btc

    2. Turnover of the exchange: 5.944 billion, 0.62%, 24 hours up and down

    precautions:

    1. The co founders of Ethereum believe that competition will be positive, and the world absolutely needs to see that indivial freedom is respected, and that they can freely access global IT tools. The data of these tools are not controlled by companies or companies that can use digital transformation to increase data

    Unlike paper or pound gold, code lines allow people to transfer value digitally. However, the difference between them and traditional currency lies in the source, maker and owner. These new currencies, designed by computer scientists and based on Mathematics and cryptography, are not forged, controlled or supported by the government

    3.

    Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")

    The token on the

    blockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum

    the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin

    extended data:

    Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks

    for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound

    in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale

    Hello, according to my experience, 1. First set up the rack, then fix the graphics card, and then plug the CPU and fan, memory, SSD hard disk into the slot of the motherboard, and connect the power supply and motherboard power supply

    I hope my suggestions can help you, thank you

    5. On June 12, 2017, the price of Ethernet currency broke through $400, a record high. From $8 in February 2017 to $400 on June 15, 2017, the price of Ethernet currency has increased 50 times. However, in the past two years, the currency circle has entered a bear market, and the price of Ethereum has fallen sharply. Now it is still an opportunity to short Ethereum. Investors can log on to the bitnet exchange and participate in Ethereum's short trading.
    6. First of all, what is Ethereum? Ethereum is a programming language and a platform. The Ethereum that investors / speculators pay attention to is actually Ethereum, which is a digital token derived from Ethereum - Ethereum

    whether Ethereum has investment prospects or not, we just need to see its value, From tens of dollars to hundreds of dollars of the increase, and do not say the future bubble or not, just say that this stage of appreciation of the space, it is worth our attention!
    Ethereum trading platform, at present, I recommend btctrade platform (bitcoin trading network), which is a relatively reliable trading platform in China! Ethereum was launched in 2016, and the rise of currency price is amazing!
    7. Confinement is a thing that must be done after childbirth. If you don't take delivery, the maternal body will leave the root of the disease after pregnancy, which is difficult to cure. Pregnant women can choose to take delivery at home or in the delivery center

    first of all, confinement is usually for one month. So whether at home or in the confinement center is the same, it needs to live for a month. But this time is not certain, can only be said to be at least a month's time to live. A month is a minimum time, even if the maternal recovery is fast, but also to live enough for a month. But if the maternal recovery is relatively slow, then it is not only to live for a month, it is necessary to live longer. Therefore, it is more recommended that pregnant women take delivery at home, which is more convenient and comfortable<

    secondly, confinement is the key period for a newborn baby to recover. During this period, it is necessary to take good care of the baby. The time of each confinement is different, but it is generally 30 days or 42 days, so the body will recover more completely

    in the end, the place to take delivery of the baby must choose a better place, a place with more complete facilities and better service. Otherwise, if the pregnant woman goes to the delivery center and no one is in charge, the delivery of the baby will be greatly reced

    pay attention to diet after childbirth:

    women have higher requirements for diet when they are in confinement, and many women think that there are not so many restrictions after childbirth, but as long as women are still in lactation, there are still many things to pay attention to

    1. During lactation, women should not eat food with milk returning function, such as leek, malt, etc. Many women think ginseng tonic body is very effective, but ginseng will make maternal milk, in breast-feeding, it is best not to eat. In addition, more estrogen content of food is also easy to cause milk, such as pigeons, hens and so on

    2. Women should not eat caffeinated food ring lactation. Caffeine can stimulate the nervous system. It is likely to enter the child's body through milk, causing damage to the child's nervous system and heart, and also causing indigestion

    3. Eat less salt and monosodium glutamate, too much salt will increase the burden on the kidney. And monosodium glutamate will affect the development of children, eat too much monosodium glutamate will make children appear mental retardation, growth retardation and so on

    women should not only pay attention to their diet when they are in confinement, even when they are out of confinement, as long as they are still in the lactation period, they can not do whatever they want in their diet, so as not to have adverse effects on their children.
    8. In short, this is the function of the central bank
    new currencies are usually solved through open market operations. In other words, the central bank makes its own money flow out by buying Treasury bonds (issued by the Ministry of Finance), so that the money flows to commercial banks, and commercial banks make money circulate in the society through lending
    first of all, understand currency: today's commonly referred to as currency is the paper money in our pocket. It is a medium and tool to facilitate the exchange and circulation of goods under the commodity economy. It has no value in itself and is issued and forced to circulate by the national bank. When you go shopping in China with us dollars, the shop owner will treat us dollars as a piece of waste paper, because US dollars must be converted into RMB through the central bank to be used in China
    currencies of different countries cannot be circulated in different countries. Now, with the global economic integration, there are certain economic exchanges between countries. In order to solve the trade and currency problems between different countries, two concepts of foreign exchange and foreign exchange reserve are involved
    as we all know, a country's wealth is not measured by the amount of its currency issued or owned, but by the amount of its commodities, which are the material needs of people's life, rather than money, that is, a country's proction capacity and gross domestic proct
    trade between countries can be divided into export and import as follows:
    in the case of export, if US dollar is used as foreign currency, that is to say, Chinese multinational enterprises sell their procts in the United States in exchange for the currency of other countries. For Chinese people, foreign currency is not allowed to circulate in the Chinese market, Therefore, in the Chinese market, foreign currency is equivalent to a pile of waste paper. Therefore, it is useless for Chinese export enterprises to sell foreign currency to the national bank to exchange it for RMB, and the state holds foreign currency. People's wealth is ultimately reflected in their material enjoyment, and money is only an intermediary and tool for material exchange, Our domestic enterprises give the goods they proce to the United States, while the United States only gives us foreign currency (bonds), thus forming a debt relationship: that is, China is the creditor, foreign countries (the United States) are the debtor, and foreign exchange (US dollars) is the debt relationship certificate

    for the import situation, foreign currency reserves will not be affected. For example, if foreign businessmen sell foreign goods at home to earn RMB, the central bank will take the foreign exchange reserves (US dollars) to buy back RMB from foreign investors (because this part of RMB is circulating at home and is not counted as foreign exchange reserves), It may also be that foreign businessmen take RMB to their own country to exchange for their own currency, which also forms their own foreign exchange reserves (whether the actual process is like the above, I don't know, it's not studying economy, it's just speculation). Buy back is actually a hedging process (the real sense of hedging seems to be that the central bank takes foreign exchange to buy overseas). It can also be understood as follows: foreign goods are regarded as the goods proced by the central bank and sold in the domestic market. In this way, part of the foreign exchange reserve is returned to the people through the central bank, and the debt is also paid

    generally, the amount of money in circulation of a country corresponds to the amount of goods proced by the country Material wealth corresponds to the amount of money)
    Chinese enterprises export goods, which can be seen as: China proces too many domestic goods (that is, the corresponding currency is not enough),
    domestic enterprises get foreign markets for commodity sales and exchange through the form of export, and can exchange domestic goods for foreign goods, but because of the existence of foreign currency, In fact, these foreign currencies are equivalent to the debts of foreign consumers to China's export enterprises, and these debts are uniformly assigned to the name of the national bank. This has become the country's foreign exchange reserves. The more foreign exchange reserves, the more money the state will lend. Lending is equivalent to issuing money. If a country releases too much money, it needs to issue a large amount of money, which may cause inflation (there are not enough goods, but a lot of currency in circulation). At this time, the country purchases goods from overseas through the international market, and consumes foreign goods in exchange for goods, so as to achieve the goal of stabilizing and balancing the economy. It can also be understood from another perspective that the central bank releases a large amount of money to exchange for foreign exchange reserves. The increase of this kind of money is not caused by the "invisible hand" of the market rules, but by the Central Bank of the government. If we zoom in, the increase of money will actually be inflation, and the money on the hands of the people will be devalued, The devalued part is occupied by the central bank free of charge. Therefore, it can be understood as: foreign exchange reserves are liabilities of the central bank, not assets, because it is exchanged by the central bank from the people's hands with RMB, then the people will want to cash this asset one day
    as China's foreign exchange currency is mainly US dollar, once the US economy fluctuates and leads to the depreciation of US dollar, China's foreign exchange reserves will have the risk of devaluation. The devaluation of foreign exchange reserves is also the loss of China's assets< In a word, foreign exchange reserve is a kind of debt relationship between the people and other countries (reserves are not national assets, but the money of the working people), and the people, as one of the creditor's rights, transfer the creditor's rights to the National Central Bank and hang them in the name of the central bank

    foreign exchange reserve refers to the foreign convertible currency held by a country's monetary authority and can be used for external payment, which acts as an international reserve asset. The amount of foreign exchange reserve mainly depends on the status of import and export, the scale of foreign debt and the actual use of foreign capital. Foreign exchange reserves are used for trade with other countries
    in order to increase foreign exchange, we need to issue RMB to buy, and the supply of RMB will increase, which may cause monetary expansion in the domestic market. A certain amount of foreign exchange reserve is an important means for a country to adjust its economy and realize the economic balance at home and abroad. When there is a deficit in the balance of payments (more imports, the domestic market full of foreign goods, causing domestic monetary tightening), the use of foreign exchange reserves can promote the balance of payments; When the domestic macro-economy is unbalanced and the total demand is greater than the total supply (the consumption demand increases and the goods are not enough), we can use foreign exchange to organize imports, so as to adjust the relationship between the total supply and the total demand and promote the macro-economy balance
    at the same time, when the exchange rate fluctuates, we can use the foreign exchange reserves to intervene the exchange rate and make it stable
    the performance of foreign exchange reserves is to hold a kind of financial claims expressed in foreign currency, not put into domestic proction. This leads to the problem of opportunity cost, that is, if the monetary authorities do not hold reserves, they can use these reserve assets to import goods and services, increase the real resources of proction, and thus increase employment and national income, while holding reserves gives up such benefits
    the increase of foreign exchange reserves should expand the money supply. If the foreign exchange reserves are too large, it will increase the pressure of inflation and increase the difficulty of monetary policy
    holding too much foreign exchange reserves may also cause losses e to the depreciation of foreign exchange rate
    because foreign currency can not circulate in the domestic market, the central bank not only releases a certain amount of money (through export and foreign capital) in China, but also reserves a certain amount of foreign exchange on behalf of the country. At this time, RMB is used in China, while foreign exchange itself is independent of the domestic economic operation, and is used by the central bank to maintain and increase value in the international financial market.
