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. Ethereum blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.

recommendation: this book is mainly for programmers. Combined with API programming, we can tell you the principle and usage of cryptocurrency, as well as how to develop related software. For non programmer readers, the first few chapters of this book are still applicable as in-depth introction of bitcoin Book pdf download: https://quant.la/Download
5. Recently, a friend recommended to me a new investment project - etherpay, which is said to combine the hottest concepts such as blockchain and mobile payment. At the same time, it also adopts the investment mode of private fund, and the income of e-money fund e before is very high
Lao Xue has always been conservative about e-money investment. Listening to what my friend said, I don't think it's very reliable, so I paid close attention to it. It doesn't matter if you don't look at it. I really found some twists and turns in it<
let's talk about its issuer first:
FVI (finatech capital investment) is a cryptocurrency fund company from the Netherlands, which was founded in 2016, focusing on the investment of blockchain technology, cryptocurrency and related assets
the company claims to have offices in the United States, Australia and Hong Kong. It has previously launched bitcoin contracts (456% of profits) and Ethereum contracts (the current contract period is not expired, but it claims to have positive profits). This sale is the company's new project ICO contract - Ethereum payment
what is etheric payment?? I found the relevant white papers and dozens of pages of PDF documents. I was dazzled by them. After studying them all afternoon, I finally understood that the so-called Ethernet payment is not only the name of electronic currency, but also the name of a transnational electronic payment project
according to the white paper, Ethereum is a general decentralized market based on Ethereum blockchain. In short, it is a Taobao or Amazon that can pay with e-money, and there is also a debit card for Ethereum, which can be used for cross-border consumption and can withdraw the e-money at any time. The most important thing is to pay through Ethernet. The service charge of online or cross-border payment is only 0.88%, which is lower than that of traditional e-commerce or bank
as an investment project, the most attractive thing is its income. Taifu private placement project plans to issue 800 million tokens, accounting for 80% of the total issue. The private placement period is one year, and the starting price is $1.00, which is expected to rise to $6.40 after the lock-in period (52 weeks), so if the first batch of purchase income is considerable
but Lao Xue, I'm a professional at least. As soon as I say that, my career sensitivity tells me that etherpay is not as beautiful as it says
for the online payment and cross-border payment claimed in the white paper, I can't tell the authenticity of such a large project for a moment, but I'm sure it's a difficult problem to realize it. First of all, cross-border payment and ether payment debit card have basically crossed the bottom line of central banks. E-money is not recognized by all countries. In addition to the possible capital outflow caused by cross-border payment and the impact on traditional commercial banking business, I think our central bank can not pass this pass. Let's talk about online shopping and e-commerce, because etherpay is equivalent to re establishing an independent payment platform, which can move the cake of traditional Internet giants. It will be fresh for Ma Yun and Bezos to watch it thrive and grab their own jobs
there are many difficulties in realizing the "lofty ideal" of this project, so whether this project can achieve this degree of profitability naturally has to be questioned. The project is unreliable. Isn't there a way to sell tokens? Let's study token appreciation
since the whole project is based on Ethereum technology environment, it is natural to check on Ethereum before investment. As a result, the white paper says the name of the token on Ethereum - ethepay, and it has been put on sale since August this year. It should be valuable now, but the value of ethepay found on Ethereum's website is at present $0@0Eth In other words, at present, the intrinsic value of aether payment token is "air"
in order to avoid my mistake, Lao Xue checked all the links similar to ethepay and Epay (including the differences between case and case), and found that all the links had zero value. I doubt that the etherpay project is an "air currency" ICO project in the final analysis, but the packaging is more realistic and advanced
seeing this, we should understand what is the situation of the etheric payment. The project itself and the future appreciation space of the token are basically impossible to make money. If we rely on the development of the MLM mode to get the Commission, we can still make some money. So whether you can participate or not depends on your IQ and conscience.

9. The issuance of futures and other derivatives will expand substantially. The debate on whether derivatives trading is stable or undermines the stability of the underlying market has lasted for decades, with dozens of papers written by leading economists. A 1976 paper analyzed the onion and potato futures market and concluded that derivatives, in fact, tend to have more and more proction shocks on the price, thus recing the volatility
this paper analyzes the same problem with bitcoin: the futures market has been launched for some time, allowing researchers to draw preliminary conclusions on its impact. The researchers found that the effect was not linear: Although the first trading period actually led to higher volatility, then graally declined, establishing a strong causal relationship in the last period
"from a professional perspective, market makers prefer to use settled and closed markets; Material object; Contracts to hedge futures contracts, thereby greatly recing the risk of potential settlement price manipulation, "he explained“ Through a cash settlement contract, the settlement price will never really be effective at maturity. "
the difference between cash settlement and physical delivery futures is how to deal with the underlying assets: in the former, transactions are only written off mathematically according to the reference spot price, while in the latter, the assets are actually e
"as a result, the buyers of these [cash settled] contracts seem to be speculators, using leverage," he continued“ Once the long-awaited physical contracts are listed, I expect most cash settled contracts will lose their attractiveness and the spot market will stabilize. "
at the end of last week, the trading price of bitcoin was in an incredible state of tension. Bulls failed to take charge of cryptocurrency, while the market was quite good. As pointed out earlier, when bitcoin trades at a smaller price in a very short period of time, a breakthrough move is likely to come
for most of this month, Ethereum enjoyed a strong upward movement over the weekend after the territory was depressed. Looking at the ETH / BTC chart, it seems that cryptocurrency has surpassed bitcoin in the short term, despite the warning of MACD index that there may be a bearish correction soon
the level of $10000 is the key support area that sellers need to break through this week. The weakness in this key technology area may be the trigger for the bearish attack on BTC / USD against the current monthly trading low
in the short term, it is important for sellers to force the price to be around $10260 at the weekly fulcrum to gain control over the price action, and to encourage testing of the previous week's trading lows of BTC / USD pairs.
