Where is the Ethereum fork coin

2.

The capacity of a block in bitcoin is 1m (megabytes). A transaction is between 250 and 500 bytes

according to this algorithm, a block contains about 4194.3 transactions

the confirmation time of a block in bitcoin is 10 minutes, so the seven transactions that a block can process per second may sometimes be less than seven

What are the consequences

The bifurcations of

bitcoin are divided into hard bifurcations and soft bifurcations

hard fork means that when the block format or transaction format of bitcoin changes, the UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes

the upgraded nodes can verify the blocks proced by the non upgraded nodes, and they continue the chain they think is correct, so they are divided into two chains

What is soft bifurcation

soft bifurcation means that when the data structure of bitcoin transaction changes,

UN upgraded nodes can verify the blocks proced by upgraded nodes,

and upgraded nodes can also verify the blocks proced by UN upgraded nodes

In September 2017, the central bank and other seven departments jointly issued the "notice on preventing the financing risk of token issuance", which defined ICO (initial coin offerings) as unauthorized and illegal public financing, suspected of illegal selling token bills, illegal issuing securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities

in 2017, ICO became very popular relying on the concepts of "digital currency", "blockchain" and "smart contract". However, only by publishing a "white paper" through a few people's team, and even some can start financing activities without a white paper, this operation mode has laid great risks for investors, and the outside world has always disputed the legitimacy of ICO. In September last year, the central bank and other seven departments gave a clear definition of ICO and stopped all kinds of token financing activities. Seven departments said in the announcement that token issuance financing is essentially an illegal public financing behavior without approval, and is suspected of illegal sale of token tickets, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities

However, after the ban of ICO, a new way of playing the coin circle, IFO, has sprung up. The so-called IFO refers to the branching currency issuance based on mainstream currencies such as bitcoin and Ethereum. On the basis of the original blockchain of these mainstream currencies, another chain is split according to different rules to generate new digital currency. People who hold mainstream currencies can get new currency after bifurcating in the process of IFO, and IFO has become a new means of virtual currency financing

on August 1, 2017, the birth of BCH marked the first generation of bifurcated coin in the coin circle. The size of bitcoin block is only 1m, and the smaller the block is, the smaller the capacity is, the slower the bitcoin transaction will be. In order to solve the problem of bitcoin block congestion, BCH blockchain successfully separated from the main chain in block 478559, resulting in a new cryptocurrency. The default block size is 8m, which can also realize the dynamic adjustment of block capacity. At the same time, people who used to hold bitcoin can get BCH for free at a ratio of 1:1

since its birth, there have been different opinions about whether BCH is a new branch of bitcoin or another kind of "counterfeit currency". However, after several ups and downs, the price of BCH began to develop steadily. As of 20:30 p.m. on February 26, the price of BCH reached 8058.8cny, and that of BTC was 67558.69cny, according to the data of fire coin

following the success of BCH bifurcation, more and more new virtual currencies have been proced through IFO, such as BTG (bitcoin gold), BCD (bitcoin diamond), SBTC (super bitcoin), etc. Chen Yunfeng believes that according to the explanation of the technical level, part of the forked currency is the upgrading or improvement of the original technology. If it is a forked currency in this sense, it is difficult to say that it has no value. Moreover, when the regulatory level repeatedly prompts the investment risk of virtual currency, the investment value should be judged by the investors themselves

Shi Qingwei, the founder of sharing finance, said that IFO is a new way to play in the past two months, and most projects generated by IFO have no investment value. Some IFO issuers believe that they are not raising funds through ICO, but a fork of mainstream currencies such as bitcoin and Ethereum, which have a large number of users. After users get the forked coins, they usually ask to join the transaction, and then the issuer of IFO will get a huge profit because of the number of forked coins g in advance. He further said that most of the bifurcated currencies proced by IFOS have no investment value and even higher investment risk than ICOS

"pre dig" fork currency or there is a risk of fraud

so, how does IFO make money According to the daily economic news, miners develop bifurcated coins in bitcoin blocks through technical means, and then distribute the developed bifurcated coins to bitcoin holders in proportion, and gain value in the transaction and circulation. Some of them will also be traded and circulated through the digital asset exchange. It is worth noting that most of the forked coins will be "pre g" before they are officially released. The pre g forked coins are equivalent to those obtained free of charge, so the founders of the forked coins can easily make profits. In the market, some people think that IFO in the name of "pre digging" is actually a more naked game of token issuance

on November 15, 2017, the domestic well-known super bitcoin team announced that it will implement the bifurcation at the 498888 height of bitcoin blockchain on December 17, and start the technical test of zero knowledge proof and intelligent contract supporting Turing complete, and expand its block to 8MB. It will also launch the intelligent contract in early March 2018 to increase the scalability of BTC Zero knowledge proof will be launched by the end of May 2018, and dynamic checkpoints will be removed by the end of November 2018 to realize fully decentralized mining. If the split is successful, a new split coin, SBTC, will be proced. The original bitcoin holders will give it away one by one, with a total amount of 21.21 million. Among them, 210 thousand are pre g by the split team foundation, which is mainly used to encourage early developers to invest in ecological construction and foundation operation

Song Qinghui, a famous economist, said that e to the lack of regulatory policies and the extremely low threshold of user participation, IFO itself may be suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising and financial fraud. Many new virtual currencies born through IFO have little value, and there may be fraud and fraud, Investors need to pay enough attention

According to Shi Qingwei's analysis, on the one hand, IFO will cause great division in the community; On the other hand, the people who issue IFO are basically some investors, and few of them really do the Ifo project in a down-to-earth way. Because they do not have strong executive power and values, it is difficult to do the Ifo project. To put it bluntly, some IFO projects are short of money, and they will not do it after cash out, and there is no particularly big risk. Just intensify market acquisition and cut leeks. The most typical risk is fraud risk, and the other is the risk of market operation. Some investors have been trapped in the Ifo project

according to Zhang Yexia, senior researcher of Yingcan consulting, first of all, there is no clear definition of IFO financing activities in China's law, and there is a risk of being prohibited; The second is fraud risk. With the rise of the concept of IFO, it is easy to attract criminals to use concepts such as "mainstream currency bifurcation" and "blockchain technology" to attract investors, but in fact there is no so-called token issuance and technology research; The third is the technical risk. At present, the technologies and standards of mainstream currencies, such as bitcoin and Ethereum, are different. There is no same technical standard, and the technical level is also different. Therefore, the hidden dangers of technical security can not be ignored

Chen Yunfeng believes that for the financing behavior in the name of IFO, the investors can only obtain the value-added income through the digital currency trading market without the actual application scenario of the bifurcated currency itself. This form of financing activity has not been clearly defined in law and needs to be regulated by the relevant departments

Hong shuning, chief researcher of the blockchain Laboratory of Suning Financial Research Institute, believes that the risks of IFO are manifested in the following aspects: first, there may be serious loopholes in changing the agreement without careful consideration; Second, the software released in a hurry will inevitably have a lot of bugs; Third, every IFO will divert some miners, causing fluctuations in the trading smoothness of bitcoin; Fourth, e to the low acceptance of bifurcated currency, the price fluctuation may far exceed that of bitcoin, which is unfavorable to investors

At the same time, Hong shuning said that in the real sense, IFO should not pre dig because it goes against the original intention of bitcoin development, fairness and freedom. In fact, like ICO, IFO is a disguised means of financing. Teams that need to make profits in advance should issue their own digital currency, not under the banner of IFO

is illegal

4. Ethereum can be said to be a very successful currency in technology. In a short period of time, it has formed a trend of convergence. No matter in the technical level or in the market level, it has received global support, and the applications developed around it are emerging in an endless stream. At present, its price has been hovering at 3000 yuan for nearly half a month. I believe that with the progress of the bifurcation, its price is likely to exceed 4000 yuan by the end of the year. As the second largest market value of blockchain projects and bitcoin projects, its value is obviously likely to rise

Ethereum uses fog computing. The data processing and applications of fog computing are concentrated in the devices at the edge of the network, rather than almost all stored in the cloud, which is an extension concept of cloud computing, which is more in line with the spirit of decentralization of blockchain. If all the storage and operations still stay on the centralized server, then it will not be a real blockchain
recently, the hot "ethereal cat" on Ethereum network has led to the congestion of Ethereum network. The problem is that the TPS concurrency per second of Ethereum is too low. The emergence of ethereumfog with fog computing will break the embarrassing situation of Ethereum network congestion, and add powerful decentralized storage and additional computing power to the chain.

the concept of fog computing may be unfamiliar to many chain friends, but it is the most important aspect of ether fog to attract investors. In fact, I have heard about the concept of fog computing for a long time, and I have always thought that fog computing is the future development direction. When it comes to fog computing, we should start with cloud computing. In fact, the cloud computing we see now evolves from the cluster of independent servers, that is, from the original centralized independent servers to large server clusters, but in the final analysis, it is still a form of centralized computing. Compared with cloud computing, which is the evolution of centralized computing, fog computing is to share computing tasks with various computing power devices around us, and realize the evolution of decentralized and distributed computing, which coincides with the philosophy of blockchain itself.

6. Fork coin, as the name suggests, comes from the concept of "fork" in blockchain. The early bifurcations of bitcoin were a compromise solution to the problem of bitcoin block expansion
bifurcation means an incomplete upgrade of bitcoin. After upgrading, some UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes, but the upgraded nodes can verify the blocks proced by the UN upgraded nodes, thus splitting the two chains
now there is a flood of counterfeit coins in the market, which are actually some bifurcated coins
a typical split coin operation is to announce a split coin and give each user a special new "split coin" or "candy" in a ratio of 1:1
after users generally get the new currency after the split, there will be a natural demand for trading. At this time, public opinion can be guided, and the huge number of users and trading demand force the exchange to put on the currency
after the currency is put on the exchange, the holders of the forked currency first use a certain amount of capital to pull up the forked currency, create the illusion of pursuing, and then sell their "pre g" forked currency for arbitrage
however, players can also think that some forked coins are valuable, so they can follow up. Therefore, the exchange of forked coins is also valuable. There are still many such activities, such as bitfinx, coin rise, coin safety, etc.

7. Yes, it is estimated that an Annet 3, safe, and the others are all issued tokens. This is the public chain.

8. Ethereum fog, or ETF for short, is a branch chain of Ethereum, which is designed to solve the problem of distributed storage and distributed computing power that Ethereum lacks. In the later stage, it will switch to the hybrid mining of pow + POS. The original coin is ETF

after Ethereum bifurcates into etheric fog, the two will exist and develop together< br />

9. This number is not fixed, because the price of bitcoin is constantly changing. The highest price of bitcoin is more than $19000. At present, the price of bitcoin is around $4000. You can log in to the bitcoin exchange to view the bitcoin market in real time.

10. Okex is the largest bitcoin exchange in the world. I'm sure you can buy it.
