what is Ethereum:
Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. Blockchain technology is one of them
Ethereum platform can safely run any program users want
advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum
what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application
The design of Ethereum is very flexible and adaptable
Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields
blockchain applications of Ethereum
Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc
Ethereum has achieved more than 100 blockchain applications by many start-ups
Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged
the relationship between Ethereum and blockchain:
Ethereum is a programmable blockchain
Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes
in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
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 theblockchain 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
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum. The concept of Ethereum was first inspired by bitcoin by vitalik buterin, a programmer, between 2013 and 2014, and now it's 2.0. Ethereum 2.0 is also something that the whole coin circle is waiting for. In order to celebrate the birth of the genesis block of eth2.0 on December 1, chinacoin officially supports the exchange of eth2.0 verification nodes at 17:00 Hong Kong time on November 20, 2020. It will invest its own eth in the verification node mining and exchange qeth to obtain liquidity. It will participate in the mining as soon as the exchange is received. Now it will give back to the user's welfare. The top 1000 eth enjoy the over exchange of qeth according to the ratio of 1:1.02. Compared with eth2.0, qeth has too many advantages: liquidity is guaranteed, users do not need to bear the technical cost, the threshold of participation does not need 32 eth, as low as 0.1eth, nodes are maintained by the platform, and the revenue is distributed according to eth2.0< br /> < br /> < br />
etc (Ethereum Classic) is a bifurcated currency that Ethereum hard bifurcates after 1920000 blocks, and its function is very similar to Ethereum. Etc adheres to the concept of decentralization and supports the consensus mechanism of blockchain guarantee. Etc firmly believes that once the blockchain starts to run, its development direction will not be controlled by any central team, but will be determined by the consensus of the people participating in the whole network and the consensus of the computing power of the whole network
the Ethereum blockchain hard branching in July 2016 aims to transfer the Dao funds stolen by hackers to an account controlled by investors, and let the old transaction records be forgotten by history. Most Ethereum developers are involved in the reversal, as are exchanges, startups and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old record. As a result, a small number of miners continued to use the original blockchain as a protest. They described the hard fork as a capital withdrawal for the abandoned project of the Dao. So Ethereum classic (etc) was born
2. Detailed parameters

compared with bitcoin, we can find that Ethereum is more difficult to develop a new encryption technology than bitcoin. This breakthrough has greatly reced the development cost and time for developers who apply blockchain technology. The emergence of Ethereum once again reiterated the need to split the center, as well as the feasibility and advantages of decentralized distributed applications, to the existing economic market, the financial sector a new direction of development and throw to the society a new entrepreneurial ideas and opportunities.
1. A little thought on currency
at present, the currency issued by all countries in the world is basically credit currency. For example, the US dollar has been decoupled from gold since the Bretton Woods system. It is generally believed that the value of the modern dollar is supported by the national credit, or national strength and military strength of the United States
however, this is specious. Because the national strength and military strength of the United States cannot be quantified, who can tell me how much the national strength and military strength of the United States are worth? Since it is impossible to quantify, how can we ensure that the US dollar is not printed too much? In fact, there is no guarantee. On the other hand, it says "in God we trust" on the dollar, which is to tell you clearly that the dollar is actually a kind of faith. It's like trump supporters shouting, "America! USA! ", People's trust in the dollar is not purely rational, but a mixture of rationality, pride, sacredness, speciousness and habitual thinking
and this kind of trust is also fragile. In recent years, for example, the Thai baht and ruble have dropped by 40% or 50% overnight, which is also common. Even more outrageous, for example, the government of the Republic of China basically cheated on the golden yuan
bitcoin is also true. Its value comes from trust, but it is not backed by the government's credit endorsement. The letter of bitcoin is a more pure letter, because it is more invisible than the legal coin, but there is a small group of people who believe in it, such as me. This kind of letter comes from the simplicity and strength of bitcoin technology, from the ideas beyond the times contained in it, from the dissatisfaction with the existing monetary system, and from the natural yearning for progress of human beings
2. Bitcoin price and reflexivity
Buffett's value investment theory is very popular: because of people's fear or greed, the price of a thing may temporarily be higher or lower than its value, but it will eventually return to the value itself
Soros's view is that because of the fragility of human nature, a thing can never return to its value. That is to say, the correction must be over correct. When the value of a thing is absolutely undervalued, then in the process of rising, people's awareness of its rising is constantly strengthened, which often leads to crazy buying, and the final price will rise to its own value, and vice versa
in this process, the rise of price leads to people's pursuit of a thing, and people's rising expectation will continue to push up the price of this thing
Soros calls it reflexivity
for example, there is a prophet in the village. He told us that gold would go up and we should go to buy gold. Everyone flocked to buy gold. The supply of gold was in short supply, and it rose as expected. So everyone said that the prophet was right
this process has nothing to do with the basic value of gold or the actual demand for gold
if you look at it with a magnifying glass. In this process, the bullish view of gold is constantly strengthened. Because gold also rose in the process. If in the first rise callback, someone sold. When it goes higher for the second time, this person will feel that his operation is particularly stupid, so he will not easily sell when he buys again next time. Even if he sells again next time, there will always be a time when he will "learn to be smart" and no longer sell
man is also a social animal. So this expectation of rising will continue to spread and "learn" from each other, aggravating this weakness of human nature
often when a bubble burst, most people could not escape. A few rational people can run away, a few win the majority and make a lot of money. In the book mob, it is said that the IQ of a group is often lower than that of a person. In management, this is called herding. In China's stock market, this is called "retail dividend". You don't see how many people earn money every day on the platform, even wealth is free.
this may be found from the contract law and the losses caused by violation,
