DTV share, Ethereum is an open source public blockchain platform with intelligent contract function. It provides decentralized virtual machines to handle point-to-point contracts through its private cryptocurrency, Ethernet. Key points: open source, smart contract function, public chain platform, Ethernet
2. After nearly two years of bear market in the currency circle, the currency price of Ethereum has now dropped to more than 900 yuan, and the current downward trend continues. Short Ethereum is now a better trading strategy. At present, digital currency exchanges that can be short, such as coin an, fire coin, bitnet.
3. Ethereum is not a kind of currency, but a decentralized intelligent protocol. It can be understood as a huge global account book. The logic of this intelligent protocol does not need a specific server to support its daily operation. Instead, it is the protocol terms given by the executors before entering among the scattered users. This is an application evolved from decentralization
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.

4. Note that Ethereum is 2.0 now. As of 13:57 on the 4th, the current deposit contract address of Ethereum 2.0 has received 1000098eth, and 31252 addresses have completed the mortgage of 32eth. With the increasing number of mortgage, the annual yield of mortgage will graally decrease. After the mortgage amount reaches 1 million eth, the current annualized yield is about 15.7%. Zhongyuan, a well-known exchange, has taken the lead in opening the mining channel of eth2.0 verification node, and then launched qeth. Users can invest their own eth in verification node mining and exchange qeth to obtain liquidity, and then participate in mining. Compared with the disadvantages of eth2.0, qeth has too many things: the liquidity is guaranteed, the user does not have to bear the technical cost, the threshold of participation does not need 32 eth as low as 0.1eth, the nodes are maintained by the platform, and the income is distributed according to eth2.0.

About 1625 RMB
The system ofEthernet coin is the most widely used public blockchain system supporting complete application development
compared with bitcoin, Ethereum belongs to the category of blockchain 2.0, which is a new blockchain system designed to solve some problems of bitcoin network
the design of bitcoin is only suitable for the scenario of encrypted digital currency, it does not have Turing completeness, and it lacks the concept of saving the real-time status of the account, and it also has the problems of efficiency and resource waste caused by POW mechanism
The blockchain network ofbitcoin has the defect of insufficient scalability. As bitcoin attracts more and more attention of developers and technicians, some users try to use bitcoin network for other digital currencies or other applications
However, with the development of Internet, it is difficult to develop blockchain applications independently. Users need to master a lot of software and hardware development capabilities and encryption algorithms, which makes the application of blockchain not so easy for some users
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!

It depends on the electricity bill, and the efficiency of mining
the most efficient is Claymore on GitHub. The algorithm is very good, but the author has 2%
because of the wall, the download of GitHub will often have problems
< P > I modified the code to remove the author's extraction. Students who want to mine can try Claymore, Give a link to the network disk ~ students who are inconvenient in GitHub can download it from the network disk, double-click the EXE file ~ but remember to change the account to your own ~network cloud link - Claymore algorithm optimization version
8. Core developer Mike Hearn: why bitcoin should be forked

Yes, it's coming. The community is beginning to separate, and bitcoin is about to bifurcate: including software, and perhaps blockchain. The two sides of the split are bitcoin core and the micro variant program based on the same program, called bitcoin XT. On August 16, Beijing time, there is now a full version of bitcoin XT
this bifurcation has never happened before. I want to explain this from the perspective of bitcoin XT developers: it can't be said that it hasn't been communicated enough
bitcoin bifurcation, this topic may make many people curious, so this article is written for ordinary readers. It doesn't involve the knowledge that has been debated before
the original version of bitcoin was carefully arranged by Nakamoto, and has always been very clear. The debate is about growth. In 2008, he answered the first question about the design of bitcoin, saying:
visa processed 37 billion transactions in fiscal year 2008, or an average of 100 million transactions per day. So many deals require 100GB of bandwidth = 12 DVDs or 2 HD quality movies = about $18 of bandwidth at the current price
assuming that the bitcoin network reaches this scale, it will take several years. By then, sending two HD movies over the Internet may not be a big deal
at that time, he was more tired of bitcoin expansion than any of us. His plan is to make bitcoin popular from the beginning, and he knows that this success will change how people use his system. In 2010, he said, "it's good that we keep [blockchain] files as small as possible
the final solution will not care how big it (blockchain file) becomes
but now, while it is still small, keep it in a small state, and the growth of new users will be faster. When I finally implement client only mode, it's no longer a problem
"
in 2011, through a series of calculations, I expanded the expansion intuition of Nakamoto in detail: if bitcoin becomes so popular, will it completely replace visa? The answer is that his plan is credible - you don't need anything else but a computer, even if there's so much traffic. Before he left, I also implemented the model he talked about
it was Nakamoto's plan that brought us together. It has changed the lives of thousands of people around the world. Some of us give up our jobs, others devote their spare time to the project, others set up companies and even travel around the world. This is an idea that ordinary people can complete mutual payment through blockchain and create this global community
that's the vision I signed, and that's the vision Gavin Andresen signed, and that's the vision signed by millions of developers, founders of startups, evangelists, and users around the world
and this vision is now in danger. In recent months, it's clear that a small group of people have completely different plans for bitcoin. These people have never really understood Nakamoto's intention because they are worried about success, if the technology has never been improved, if people can't run bitcoin on their home computers? Doesn't this make bitcoin move away from centralization and more like banking? What if people start to rely on bitcoin, even if it's imperfect
now, Nakamoto has chosen to disappear, and they want to make a major change: substantially increase transaction costs, end support for mobile P2P wallets, give up unconfirmed transactions, and many things that have never been found in the project's founding documents
the so-called lightning network, which is about to be promoted as a substitute for Nakamoto's design, does not exist. The white paper describes that it was announced earlier this year, and if it can be realized, it will be a huge departure from the bitcoin we know and love. Pick one of the many differences, and a bitcoin address won't work. What they will be replaced with has not yet been worked out (because no one knows). There are many other surprising pitfalls that I mentioned in another article. What will it eventually proce to make our existing bitcoin network better? It is still extremely unclear
what happened to the free market
in theory, none of this should be a problem. Lightning network is built on the blockchain, but it needs a rather trivial upgrade process to achieve the best function. Of course, people are willing to explore this direction, which is entirely possible. If the jobs they set up are better than the existing ordinary bitcoin network, then the market will choose their way, if so... It is fair competition for them! The current design of bitcoin is unlikely to be the final version for payment. This is a reasonable imagination, one day it will be eliminated in the competition, or enhanced by something else
but our system is working today. It has an ecosystem, including developers, exchanges, wallets, ATMs, books, applications, conferences, and many people have learned how it works
if there was a free choice, would people decide to move to a completely different system
we don't know, but the people who are pushing these things don't want the market to make a decision. That's what happened
a long time ago, Nakamoto set up a temporary "mixed brand assembly computer": he limited the size of each block to 1 MB. He did so in order to keep the blockchain in a small state in the early days, until we now call it the creation of SPV wallet (that is, what Nakamoto calls "client only mode"). As mentioned above, when the time comes, it can be adjusted. It has never been said that it is permanent. In the end, it becomes irrelevant. In 2011, I wrote the first SPV tool with my respected colleague Andreas schildbach, and we built the first and most popular Android wallet together. Since then, SPV wallets have been used on major platforms. Therefore, Nakamoto's reasons for this temporary restriction have been solved a long time ago
with the continuous growth of bitcoin, its blocks are also growing. Reasonable traffic forecasts show that the block will reach the current system limit sometime next year, at the latest in 2017. Another bubble or pressure cycle will force us to exceed that limit before, and the result may not be beautiful.
so it's time to raise the upper limit, or delete it completely. That's our plan, and the problem starts: those who don't want to see bitcoin expand have decided to postpone the process. They saw a beautiful, one-time opportunity to forcibly transfer bitcoin's predetermined path to a completely different technological trajectory. They don't know what this alternative design will be, and of course they haven't built it yet. But it doesn't matter. They believe that by blocking the growth of the blockchain, they can "motivate" (that is, force) the bitcoin community to switch to different things, something more in line with their personal technical taste
why restrict blockchain
so far, I haven't explained much about these people or who they are. I think it's a very time-consuming and laborious thing to name names in this article, and it seems to be futile in the end. Presumably those who care about this matter already know it, and those who don't know it can't recognize the people who are involved in it
I just want to say that they are very few people who have access to the bitcoin core code base, or those who are convinced by their arguments
therefore, we will not discuss these arguments here, which has been too much. Gavin and I have written articles to analyze the questions raised by everyone to refute them. Sometimes the answer is some common sense, some will be more in-depth, need more work, such as network simulation
the best place to understand these controversies is in Gavin's blog. I hope to find a link to a collection of opinions similar to those refuting Gavin's point of view, but none of them
to sum up, in the long and hard debate, several different opposition groups:
if bitcoin approaches this limit, we will be stimulated to create something better
the limit should be raised, but it is not ready (the actual time is not specified)
if bitcoin is expanded and becomes more centralized, it will no longer be bitcoin< Other people: if the objections you support are not listed above, please check Gavin's blog and find out the answer
the first point may become a reality one day, but it is not comparable with the theoretical system on paper. But no one who has seen any alternative solutions on the table thinks they can be implemented within 12 months (see another example in the last paragraph, for example)... Even assuming they are better. This is also an example of the nirvana fallacy:
the nirvana fallacy refers to the name of the informal fallacy of some unrealistic and idealized substitutes for something more practical. It can also refer to the tendency to think that there is a perfect solution to a specific problem, so it is also called perfectionism fallacy
it's obviously advantageous to create an imitative dichotomy for a current choice. But it's also totally incredible. One who uses the nirvana fallacy can attack any opposing idea because it is imperfect. According to this fallacy, the choice is not between real-world solutions. One is a realistic solution, and the other is an impractical solution, which is the "better" choice between the two
the answer to the second objection is too vague. It is reasonable to believe that the overall upgrade of each bitcoin node may take one year, and the actual bitcoin network capacity overload will cause serious damage. We really should be ready before that. In the bitcoin development mailing list, there are two people who have professional capacity planning experience, and both of them have
