2. The double precision values of 480 and 580 are basically the same, which are 1 / 16 of the single precision, about 360gflops. In fact, these two cards are not easy to use. The double precision of 280x is three times that of this, about 1000gflops.

3. Rx470 and rx570 are the most cost-effective ones (before 1500), and their mining performance is no worse than 480 and 580, but they are much cheaper. We can also consider the lower 460 and 560, and other models are not worth considering.

bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher

ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.

different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum

at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s

the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining

compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.

from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly

The ASIC mining machine of

bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand

5. The concept of fog computing may be unfamiliar to many chain friends, but it is the most important aspect of ether fog to attract Xiaobian. In fact, the concept of fog computing has been known for a long time, and I always think 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 the existing cloud computing, fog computing does not rely on the remote server located in the central computer room, but intelligently connects to the nearest distributed computer resources, so as to achieve the most efficient utilization of computing resources. This topology is characterized by decentralized peer-to-peer network, which is a perfect match with blockchain. If cloud computing represents efficient computing power in the Internet era, then in the era of Internet of things and value networking blockchain, fog computing should be the most efficient way of computing power networking
therefore, compared with the evolution of cloud computing, which is a kind of centralized computing, fog computing is to share computing tasks with all kinds of powerful devices around us, and realize the evolution of decentralized and distributed computing, which coincides with the philosophy of blockchain itself. However, it is necessary to encourage the owners of distributed computing resources to contribute computing power to the fog computing network. It is not only difficult for centralized enterprises (such as Cisco) to organize supply and demand market settlement in real time and monopolize, but also contrary to the decentralized distributed philosophy of fog computing itself, which is difficult to be widely recognized, It is difficult to find a satisfactory solution on how to settle the compensation of fog calculation reasonably

we can see that Amazon's AWS, Microsoft's azure and Alibaba's aliyun are all centralized operators operating centralized computing services, and the combination of blockchain value network and cloud computing network, which are both decentralized philosophy, is almost perfect. Ethereumfog is born for this purpose. Upgrading Ethereum based on Ethereum will really bring fog computing to us. In the near future, many personal computing devices may contribute their computing power to do useful things on ethereumfog chain, and do not waste every resource to earn corresponding returns< We use cloud computing, but it runs in the remote data center; Fog is close to the ground and lingers around us. Fog computing makes both computing and storage decentralized distributed on the devices around us. The combination of blockchain and value Internet makes more people willing to let their computing resources participate in it. The organic combination of supply and demand is becoming more powerful. Ethereumfog etherfog (ETF) is opening the door to the new world of Ethereum.

anonymous user's reply
according to the price of Ethereum / Ethereum eth of China bitcoin chbtc on May 4, one Ethereum / Ethereum eth is about 62 RMB. Anonymous user's reply
the current latest currency exchange: 1 RMB = 0.1584 US dollars, and the transaction price is subject to the bank counter<
anonymous user's reply
at present, the price of Ethereum is about $200. Ethereum is a digital currency next only to bitcoin and has a good investment value. The price will definitely rise sharply in the future. Anonymous user's reply
some institutions predicted that Ethereum will rise to $2500 by the end of the year, but it seems unlikely in the current market
domain Kingdom's latest Ethereum price is $166, down 16% from yesterday
although the price of Ethereum continues to decline, there are still many investment opportunities
nowadays, many people invest in Ethereum through virtual currency trading in the realm Kingdom, which is not affected by the rise and fall of prices, but also can invest less money in the shortest time to obtain more profits
- knowledge about the historical trend of bitcoin - in history, bitcoin has experienced three ups and downs
when? What is the reason? I cut it out today
for the first time, bitcoin soared from US $0.75 to US $30 in just two months from April to June in 2011 to 2013. After careful calculation, compared with us $0.0076 when bitcoin was born, it increased by 40000 times. It's too scary
then why does it suddenly rise from 0.75 to $30? It turned out that bitcoin and sterling exchange trading platform went online in those two months
then some mainstream newspapers in the United States began to report on bitcoin, and as soon as the news came out, global investors simply flocked to join the ranks of speculation
at that time, the value of bitcoin was not very obvious. These people had nothing to do when they were full
from June to November of the same year, bitcoin fell from $30 to $2, which was frightening when it rose and even more frightening when it fell, with a 93% decline. It is estimated that the newly added small white vegetables will be scared to death
the root cause of such a sharp decline may be related to the hacker attack on Mt. GOx, the world's largest bitcoin trading platform, in June 2011
hackers certainly won't let go of the rise
from 2013 to 2015, from January to December 2013, bitcoin rose from $13 to $1147, an 88 fold increase
compared with the birth price, it has increased by more than one million times
ring this period of time, hacker attacks also occurred, causing price callback
however, it is still bullish and keeps the price of 1000 US dollars
the main reason for the rise is that the debt crisis in Cyprus has triggered a crisis of trust in traditional financial institutions
then, in the second half of 2013, some European countries introced policies that are beneficial to bitcoin. Well, more and more people know about bitcoin
naturally, speculators will not let go of this opportunity
as soon as these speculators appear, I know that there is nothing good about it. It's not easy to rise, but it's plummeting again
from December 2013 to January 2015, bitcoin dropped from $1166 to $170, a drop of 85%
the reason for the sharp drop is probably related to the notice on preventing bitcoin risks issued by the five ministries and commissions of the central government in December 2013
because bitcoin plummeted 92.5% in 83 days after the announcement
at that time, digital currency was not as influential as it is now< So prevention is right
the third sharp rise and fall, from 2017 to now this period is the most important two years of bitcoin, because bitcoin rose from $789 to $19878 in one year of 2017
24 times increase
compared with the birth price of bitcoin, it has increased by 20 million times
reason: in this year, the underlying technology of bitcoin, blockchain technology, rose strongly, driving the value of bitcoin soaring
at the same time, the outbreak of Ethereum's ICO triggered a surge in bitcoin
twenty thousand dollars has made many people become local tyrants overnight
it's not just speculators. People on the earth know about bitcoin, which will surely attract more vampires and the murderous eyes of many countries
No, it is estimated that a long bear market rarely seen in the history of bitcoin will come
since December 17, bitcoin has been in a bear market, falling from $20000 to more than $6000
the decline of 60% makes many people begin to doubt their life
there are many reasons for this decline. Global regulation has become stricter, exchanges have been attacked all the time, and the vulnerable hearts of investors are under heavy pressure
