1. Eth is a kind of digital token of ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of tens of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform

2. A virtual currency with a wallet doesn't mean it's more professional and advanced. The existence of digital currency wallet is the premise of currency existence. Currency without wallet can be identified as fraud
mainstream digital currencies such as bitcoin, Puyin, Laite, Ethereum and dogcoin all exist in wallets, and wallets existed before the release of such currencies.

4. In May 2017, investors and onlookers saw bitcoin worth more than $2300. This number marks the highest price of bitcoin in its entire career. Due to the success of bitcoin in the past few years, many investors are attracted by it and other cryptocurrencies
however, bitcoin is not the only cryptocurrency with rising value. The value of another cryptocurrency called Ethereum has been increasing since January 2017. From $8.24 to $203. Up 2367%
investors are worried that in the past few years, cryptocurrencies have gained the favor of many investors who are looking for other investment methods than traditional ones. Although most investors still invest their money in traditional financial markets, such as the stock market and foreign exchange market, many of these investors have begun to worry about the economic climate of the world economy
recent events have made us aware of the instability of traditional financial markets such as the stock market and foreign exchange market. Many investors have been looking for other ways to invest their money
with the creation and popularization of cryptocurrency and its rapidly rising value, many investors, especially those from Asia, have joined the trend of bitcoin and cryptocurrency
advantages of Ethereum
although many people are more familiar with it, Ethereum has also gained a fair share of the market with its own value. However, there are key differences between the blockchains used by Ethereum and bitcoin
the difference between the two systems is that Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
although many people may think that Ethereum may be inferior to bitcoin because its value is lower than bitcoin, this is a good thing for investors who are looking for investment channels other than bitcoin. A lower price may attract more investors because it has more room for growth. The only drawback is that Ethereum is not as established as bitcoin. In view of this, bitcoin is more secure than Ethereum<
not as volatile as before
since bitcoin was founded in 2009, cryptocurrencies have made great achievements, and they have continued to grow. In fact, the value of legal cryptocurrency has risen a lot since then
although cryptocurrencies have performed very well this year, analysts expect that when the economic situation is good, investors will leave cryptocurrencies and return to traditional investment media. When this happens, the volatility of cryptocurrency will decrease because of the decrease of demand
of course, we will still see the growth of cryptocurrency in the next few years, which will help the instry remain strong. When that happens, it's a good idea for investors to hold cryptocurrencies for future growth.

5. When it comes to money, mining is indispensable. In Ethereum network, if you want to get Ethereum, you also need to mine it. When it comes to mining, there must be a consensus mechanism
do you remember what the consensus mechanism of bitcoin is? The consensus mechanism of bitcoin is pow. To put it simply, the more work you do, the higher the amount of computation you pay, the more likely you will be the first to find the correct hash value, and the more likely you will be rewarded with bitcoin
however, there are some defects in the pow of bitcoin, that is, it is too slow to process transactions, and miners need to constantly collide hash values through calculation, which is costly and inefficient. Friends who are interested in blockchain knowledge should see such a saying:
in order to make up for the deficiency of bitcoin, Ethereum has proposed a new consensus mechanism, called POS (this is the abbreviation of English, which means "proof of equity", also translated into "proof of equity")
POS simply means the same as its literal meaning: equity, equity. The more currency you hold, the more equity you have, the higher your equity
Ethereum's POS means that the more money you hold, the longer you hold it, the less difficult it will be to calculate and the easier it will be to mine
in the initial setting of Ethereum, Ethereum hopes to build a relatively stable system by using POW in the early stage, then graally adopt POW + POS, and finally completely transition to POS. So, it's true that the consensus mechanism of Ethereum is POS, but POS is only a plan or goal at the beginning of Ethereum's release. At present, Ethereum has not yet transitioned to POS, and the consensus mechanism adopted by Ethereum is still pow, that is, the pow of bitcoin, but it is slightly different from the pow of bitcoin
the amount of information here is a bit large,
the first information point is that the consensus mechanism currently adopted by Ethereum is also pow, but it is slightly different from the pow of bitcoin. So, what's the difference between the pow of Ethereum and bitcoin: in short, the mining difficulty of Ethereum can be adjusted, but the mining difficulty of bitcoin can't be adjusted. Just like our college entrance examination, because the teaching situation and the number of students in different provinces are not the same, so the college entrance examination is divided into national papers and provincial independent proposition
Ethereum said that I am in favor of the topic by region. Bitcoin said: No, it must be the same volume in the whole country. The difficulty is the same for everyone
the popular explanation is that bitcoin uses computer computing power to do a lot of hash collisions, enumerate various possibilities to find a correct hash value. The Ethereum system has a special formula to calculate the difficulty of each block. If a block is verified faster than the previous block, Ethereum protocol will increase the difficulty of the block. By adjusting the block difficulty, the time needed to verify the block can be adjusted
according to the Ethereum protocol, the dynamic adjustment method of difficulty is to make the time interval of creating new blocks in the whole network 15 seconds, and the network uses 15 seconds to create blockchain. In this way, because the time is too fast, the synchronization of the system is greatly improved, and it is difficult for malicious participants to launch 51% (that is, more than half) of the computing power to modify historical data in such a short time
the second information point is: in the initial setting of Ethereum, we hope to achieve the transition from POW to
POS through phased upgrade
dating back to 2014, at the beginning of Ethereum's launch, the team announced that the launch of the project would be divided into four stages, namely, Froniter, homestead, metropolis and serenity. In the first three stages, the consensus mechanism adopts pow (workload proof mechanism), and in the fourth stage, it switches to POS (equity proof mechanism)
on July 30, 2015, the first phase "frontier" of Ethereum was officially released. This phase is only suitable for developers. Developers can write smart contracts and decentralized application DAPP on Ethereum network, and miners begin to enter Ethereum network to maintain network security and get Ethereum coins. The leading-edge version is similar to the beta version, proving whether the Ethereum network is reliable or not
on March 14, 2016, Ethereum entered the second stage of "homeland". In this stage, Ethereum provides the wallet function, so that ordinary users can easily experience and use Ethereum. There is no obvious technology improvement in other aspects, but it shows that Ethereum network can run smoothly
in September 2017, Ethereum has reached the third stage of "metropolis"“ "Metropolis" is composed of Byzantine and Constantinople. The goal of this stage is to introce the hybrid chain mode of POW and POS, so as to prepare for the smooth transition from POW to POS. This is the latest popular "Ethereum Constantinople upgrade". In the Constantinople upgrade, Ethereum will make some changes to the underlying protocols and algorithms to lay a good foundation for the implementation of POW and
POS
how much reward will Ethereum get for mining? Miners who win the block creation competition will get the following income:
1. Static reward, 5 ethereums
2. The fuel cost in the block, i.e. gas, we talked about in the last issue
3. As a part of the block, it includes the extra reward of "Uncle block". Uncle is uncle of uncle, and each uncle block can get 1 / 32 of the mining reward as a reward, that is, 5 times 1 / 32, which is equal to 0.15625 ethereums. Here, let's briefly explain the concept of "TERT block". The concept of "TERT block" was proposed by Ethereum. Why should we introce the concept of TERT block? This also starts with bitcoin. In the bitcoin protocol, the longest chain is considered absolutely correct. If a block is not part of the longest chain, it is called a "orphan block". An isolated block is a block, which is also legal, but it may be found later, or the network transmission is slower, and it does not become part of the longest chain. In bitcoin, the solitude is meaningless and will be discarded later, and the miners who find the solitude will not receive mining related rewards
however, Ethereum does not think that isolated blocks are worthless, and Ethereum system will give rewards to miners who find isolated blocks. In Ethereum, isolated blocks are called "Uncle blocks", which can contribute to the security of the main chain. Ethereum's ten second block interval is too fast, which will rece the security. By encouraging the use of tertiary blocks, the main chain can obtain more security guarantees (because the isolated block itself is legal). Moreover, paying the tertiary block can also stimulate the miners to actively mine and actively use tertiary blocks. Therefore, Ethereum thinks that it is valuable.

6. Ethereum one click coin, the specific technical content is not very clear, but this operation is safe? Does digital financial security allow the operation of one key currency issuing?
7.
First of all, we need to understand what is MLM:
MLM refers to the illegal behavior of organizers and development personnel to obtain wealth by calculating and paying remuneration to the developed personnel based on the number or performance of the personnel directly or indirectly developed, or requiring the developed personnel to pay certain fees to obtain the qualification to join. The essence of MLM is "Ponzi scheme", that is to say, the money of later comers is distributed to the income of former comers
However, the new type of MLM does not restrict personal freedom, does not accept ID cards and mobile phones, and does not take classes collectively. Instead, it uses capital operation as a banner to pull people to cheat money, drives luxury cars, wears gold and silver, and uses money to attract your relatives and friends to join in, and finally makes you lose all your moneythen judge whether the ether coin is a kind of MLM, whether you need membership fee, whether you need to ask your relatives and friends to join
extended materials:
Ethereum is an underlying technology platform on which developers can create distributed applications. With the application, there will be transactions. With a transaction, you need money to complete the transaction. In this way, money has value, and investors' investment has a return. If the transaction volume on the platform is larger and larger, the demand for money will be higher and higher, and the money will be more and more valuable
from the perspective of image, bitcoin creates a kind of digital gold, while Ethereum creates a country, and Ethereum is the credit currency of the country
after bitcoin, there are thousands of digital virtual currencies in the world, many of which are completely deceptive in the guise of "digital currency". Previously, Haikou Municipal Public Security cracked down on a pyramid selling organization called "Eurasian currency", which operated on the internet pyramid selling platform, making more than 40000 investors cheated, involving 4.06 billion yuan. The field of virtual currency has just started, so we need to be cautious

8. Ethereum has established a programmable and Turing complete blockchain. On this blockchain, you can realize the proction of all kinds of digital assets through a simple program, and you can also accurately control the status of the blockchain assets circulating on Ethereum by writing a program, such as whether the asset is to be paid or locked or has a quota, whether the account is a treasure list or a white list Ethereum and other digital assets, etc. At the same time, Ethereum is a programmable, flexible and complete blockchain network foundation. On this basis, we can realize more functional procts of non regional fast chain assets. For example, I use Ethereum to set up smart contracts, which can be applied in personal daily economic life and enterprise economic activities. Ethereum is a new and open blockchain platform based on the concept of blockchain and blockchain assets. It allows anyone to build and run decentralized applications on the platform by using blockchain technology. In short, Ethereum technology is blockchain technology plus smart contract.
9. Now digital currency is a zero sum game, you put money in, I put money in, I take out more, you take out less, then I make money, earn your money, so simple.
