Ethereum killer

3. 1、 EOS and graphene technology
(1) faster processing speed
first of all, as far as the underlying technology is concerned, EOS claims to be able to process tens of thousands or even millions of transactions per second. What kind of technology is used to achieve this
EOS uses graphene substrate tool to process high frequency data. Let's talk about the graphene underlay tool
graphene is actually a chemical substance. Later, blockchain developers got inspiration from the molecular structure of graphene, believing that the molecular structure of graphene can be applied to the underlying structure of blockchain. So, the graphene we are talking about now basically refers to the blockchain tool group, which is written in C + +
data show that: Based on graphene underlying technology, it can achieve an average confirmation speed of 1.5s, achieve 3300tps data throughput under limited conditions, and can reach millions of TPS, even millisecond level confirmation speed
(2) strong concurrency
in addition, EOS has strong concurrency, which is also related to the underlying architecture of graphene. Concurrency, in short, means that multiple programs can be executed at the same time
EOS is a blockchain infrastructure on which developers can build their own blockchain. Chain to chain does not affect the use of resources between each other
DAPP on EOS is independent of each other and does not affect each other. There will not be a large area of congestion e to the huge resources consumed by indivial application developers on the platform
(3) free
in addition, compared with Ethereum, the most important point of EOS is free. Free is very competitive. In the past, we had to pay fees through bank card transfer, but Alipay and WeChat appeared later. In the early stage, free transfers can be realized through applications such as Alipay and WeChat. It is believed that ring the free time, payment methods such as Alipay and WeChat were graally popularized and accepted by the public.
as we said before, Ethereum transactions need to pay gas, which means that you have to pay a certain Ethereum service charge for each transaction, but it does not need to consume EOS token to conct smart contract and transfer transactions on EOS
there are three main sources of EOS value: bandwidth and journal storage (disk), calculation and calculation backlog (CPU), and state memory (RAM). Resources are allocated according to the number of EOS held by the account, which can attract a larger number of users, so as to meet multiple business scenarios< (4) strong security
compared with Ethereum's smart contract, EOS increases security
we know that there is no legislature in the world of blockchain, so the underlying code is equivalent to the law in real life
however, when it comes to code, bugs cannot be avoided, especially for smart contracts. The harm of bugs is very great, and your digital assets will face great risks
although Ethereum has established various applications and code standards for smart contracts, they can not meet the business needs, and EOS stipulates that the task cannot be fully performed only by code
EOS believes that the source code protocol must be readable. Generally speaking, when a system error occurs, blockchain procers can distinguish what kind of bug the error is based on the readability information, and judge whether the community repair is correct through the readability information< Second, consensus mechanism of EOS: dpos
the consensus mechanism adopted by EOS is "dpos", which means "proof of entrusted rights and interests" in Chinese
Ethereum uses POS (proof of equity). In short, the more money you hold, the more rights you will have in Ethereum
then, EOS proposes dpos on the basis of Ethereum POS (proof of equity), that is, it adds a "Commission" before the proof of equity, to whom? Delegate to the supernode
in the setting of EOS, the super node of EOS should be selected from 100 standby nodes through voting by all users holding money, and finally 21 nodes with accounting rights will be selected
this is a bit similar to the "people's Congress system" in our country. A deputy to the people's Congress represents the interests of a group of people; A super node represents the interests of a group of ordinary nodes. In dpos, there is no need to solve the hash function, but the procer is elected by the holder. Therefore, compared with pow, the efficiency of dpos mechanism in dealing with transactions has been greatly improved
however, there are some defects in dpos. It needs to solve the problem of community voting enthusiasm and rece the number of nodes in order to speed up the voting process, thus aggravating the "centralization" problem
the above advantages enable EOS to rise rapidly, especially in China, the strength of EOS community is very huge
in fact, it's useless for most people to tell them how powerful EOS technology is and how much better it is compared with Ethereum and bitcoin, because it's more about how much dividend you can get from it
three what makes people say EOS is a bubble?
obviously, EOS gives people the hope to get a huge dividend. What hope
with the rapid rise of EOS, people can see the real hope of DAPP application in blockchain. People are eager to hoard enough EOS and get more chips before the large-scale outbreak of DAPP, and then wait for its price to rise tenfold, hundredfold, thousandfold...
however, the answers submitted by EOS are not so satisfactory. In terms of transaction speed, EOS can actually process thousands of transactions per second, which is far from the "million level" described in the publicity
although DAPP has really appeared, it is basically similar to "capital disk" projects or simple games with low operability and poor experience
some time ago, there was a rumor that BM, the founder, was suspected of "abandoning the ship" and running away
BM, speaking in the EOS telegraph group, said: it intends to break the original design, abandon the original consensus mechanism of EOS, and redesign a system that can perfectly solve the problems of centralization, privacy and capacity expansion. This new design will reach tens of millions of TPS...
it's hard to say the future direction of EOS, The reason why the killer DAPP didn't appear can't all be attributed to EOS, which involves the constraints of policy, development team and so on
however, compared with bitcoin and Ethereum, EOS has made some progress and innovation, so we say it is the representative of the blockchain 3.0 era.

4. Hello, I'm an old user of Feixun. It's easy for me to buy it at 0 yuan. It's simple, that is, they will return you the full amount of cash after purchase. This purchase mode has been carried out by fisun for several years, and it has never been overturned. I bought their router and air purifier, and this time I bought two C8. How to say, investment is bound to have risks, but we should be good at judging the trend. Everything will fall when it reaches the peak, and rise when it reaches the lowest point. Now it's in a bear market, it won't go up or down, but I personally think it will go up in the future. At present, Ethereum's blockchain technology is up-to-date and Turing is complete. Many experts predict that within 2-3 years, Killer Software Based on Ethereum's blockchain technology will appear. This is my personal point of view, which needs the subject's own judgment.

5. This question actually leads to a topic worthy of discussion: how do we see the "use" of the existing digital currency? Or how do we divide our understanding of digital currency

this division of cognition not only helps us understand digital currency, but also guides our behavior in the process of investment. So I'm going to analyze this topic in two or three articles
from the perspective of cognition, I divide all digital currencies into the following three categories:

the first category is that their value and consensus have been strongly recognized, almost indisputable, and have been transmitted from within the circle to outside the circle. This kind of currency is the least in the whole field of digital currency
this kind of currency typically includes bitcoin and Taiwan dollar. Bitcoin is recognized as "digital gold" and has repeatedly shown the characteristics of "sea calming needle" when the external political and economic environment is unstable; The profit model of platform currency is clear, especially the top three platform currencies have solid cash flow and income relying on the exchange
when talking about this kind of currency, both their consensus and value are highly recognized in the instry, and ordinary people can understand it outside the instry
when we talk about bitcoin with ordinary people, as long as we tell them that gold goes up, bitcoin goes up; When talking about platform currency with ordinary people, just tell them that platform currency is equivalent to the stock of securities companies, and they will immediately understand what we are talking about
although some people outside the instry do not agree with some consensus (for example, some people still do not agree with the value of bitcoin), this does not prevent ordinary people from understanding what we are talking about
the second type is that consensus has been reached, but the actual use value is still being proved, or the so-called "use value" can not show us the actual effect for the time being. This kind of currency is slightly more than the first kind, but also very few in the whole field of digital currency
this kind of currency typically includes Ethereum, EOS and cross chain projects in the field of smart contract

take Ethereum and EOS for example, they are highly expected by the instry. We hope to see that their smart contract function can proce killer applications and bring higher efficiency and lower cost to our daily life
in the past two years, Ethereum has developed a highly concerned defi Ecology (defi, decentralized finance, often referred to as distributed finance or decentralized Finance) in the instry
however, does this ecology have a direct relationship with the life of ordinary people or bring direct benefits? In fact, it does not exist at all. It is still a "niche ecology" in a small circle, far away from our daily life
the ecosystem developed by EOS in the past two years is far from the areas where we expect to bring value into play, and even there are not many people in the instry who pay attention to it
the concept of cross chain project is very novel when it first came out, and it is also considered by the instry to have great potential demand. But after a period of discussion, some people began to question whether this demand really exists
the instry has a consensus, or even a high consensus, on these currencies, but their current value is not satisfactory. Therefore, even if they are recognized by the instry, it is difficult for this consensus to be transmitted outside the instry, not to mention that ordinary people can understand these consensus and values
so we can't talk with ordinary people about what "defi" and "cross chain" are and what's the use

the third category is the currency whose consensus is still in the process of forming. The design objectives and scenarios of this kind of currency may not be understood or recognized by the instry, or even there are great differences in understanding. Their value is even more difficult to judge. This kind of currency accounts for the vast majority of the current market.

7. What is a network card

a key hardware in a network system is its adapter, commonly known as a network card. In LAN, network card plays an important role. Network card is used to input and output signals between computers. The Nic has its own interrupt number (IRQ) and I / 0 floor. The network cards include isa card, EISA card and Ethernet card used on Mac. At present, 16 bit isa network card and 32-bit PCI network card are widely used. The network card has buffer memory to store data. Similar to sound card, network card usually has its own driver. When using, the network card is inserted into the expansion slot of the computer. There is an indicator light on the network card, which indicates whether it works normally
network cards support different transmission rates, some are 10 megabits per second, some are 100 megabits per second, and some can adapt themselves to 10 megabits or 100 megabits
network card with remote boot chip can be used in diskless workstation. Diskless workstation, no hard disk, you can also have no floppy drive. Starting the computer through the network card can ensure the security of the system and avoid viruses. In addition, it can rece the cost
in notebook computers, smart PCMCIA card is used to exchange data with other computers. In the high-speed network, there are FDDI network card used in optical data distribution interface, ATM network card used in different card transmission mode, etc. The network card used for bus structure topology in LAN is the network card of BNC port, and the transmission medium section is 50 Ω Thin coaxial cable should be sealed with terminators at both ends of a network segment to form a network loop

what is a graphics card

a graphics card is what we usually call a graphics accelerator card. Its basic function is to control the computer graphics output, it can be said that it is a "middleman", it works between the CPU and the display. A high-quality graphics workstation, its CPU may not be the fastest, but enough to use, the important thing is that such a computer must have a very excellent professional display card, the speed of processing graphics alone is much faster than the CPU, the internal complexity is no less.

8. Elecoin has a killer function, that is, it can search hundreds of thousands of digital currencies. You can use code search, bitcoin code is aaa00001, Ethereum is aaa00002, if you find a specific currency, it is recommended to use the erc20 contract address of this ratio for search, because the name and code will be repeated.
