Ethereum cat Post Bar

1.

There is an essential difference between ethereum and bitcoin. What is the difference? Bitcoin defines a set of currency system, while Ethereum focuses on building a main chain (which can be understood as a road) to allow a large number of blockchain applications to run on this road

from this point of view, Ethereum's application scenarios are more extensive, which is why we say that Ethereum marks a simple monetary system in the era of blockchain

1.0, and a transformation to other instries and application scenarios in the era of blockchain 2.0

however, there is no perfect thing in the world. Although Ethereum has expanded the application scope of blockchain in all walks of life and improved the speed of transaction processing, it also has some disputes and doubts

first, the solution to the lack of scalability of Ethereum: slicing technology and lightning network

the bottom design of Ethereum, the biggest problem is that Ethereum has only one chain and no side chain, which means that all programs have to run on this chain equally, consuming resources and causing system congestion. Just like last year's very popular Ethereum game "encryption cat", when this game was very popular, it once caused Ethereum network paralysis

to improve the processing capacity, Ethereum proposes two ways: shard and lightning network. Let's introce these two technologies respectively

(1) fragmentation technology

vitalik buterin, founder of Ethereum, believes that the reason why mainstream blockchain networks such as bitcoin process transactions very slowly is that every miner has to process every transaction in the whole network, which is actually very inefficient. The idea of fragmentation technology is: a transaction does not need to be processed by all nodes in the whole network, as long as some nodes (miners) in the network are allowed to process it. Therefore, Ethereum network is divided into many pieces. At the same time, each piece can handle different transactions. In this way, the network performance will be greatly improved

however, the slicing technology is also controversial. As we all know, the important idea of blockchain technology is decentralization. Only when the whole network witnesses (processes) the same transaction can it have the highest authority. The Ethereum slicing technology is similar to the group witness, not all nodes witness together. In this way, it will lose the absolute "decentralization" attribute, and can only achieve the purpose of high performance by sacrificing certain characteristics of decentralization

(2) lightning network

lightning network uses the way of transaction under the chain. What does that mean? It means: when the participants of lightning network transfer money to each other, they do not need to confirm the transaction through the main chain of Ethereum, but create a payment channel between the participants and complete it under the chain

however, lightning network is not separated from the main chain. Before establishing a payment channel, you need to use the assets on the main chain as collateral to generate a balance proof, which indicates that you can transfer the corresponding balance. In the case that both parties of the transaction hold the balance certificate, both parties can make unlimited number of transfers under the chain through the payment channel

only when the off chain transaction is completed and the assets need to be transferred back to the chain, the balance change information of the main chain account will be registered on the Ethereum main chain, and no matter how many transactions occur ring this period, there will be no record on the main chain

another real benefit of lightning network is that it can save the cost of miners for you. At present, when we trade on the main chain of Ethereum, we need to consume gas and pay for miners. Once we move the transaction to the lower chain, we can save this part of the cost

Of course, lightning network is not perfect. When using the lightning network, the assets on the main chain should be used as collateral; And this part of assets as collateral can not be used before the user completes the transaction under the chain. This also determines that lightning trading is only suitable for small transactions

the above is the problem of insufficient scalability of Ethereum, as well as the two main solutions: fragmentation technology and lightning network

Second, there are loopholes in Ethereum's smart contract and the infamous Dao event

Ethereum's smart contract is very powerful, but there are loopholes in any code. The biggest controversy of Ethereum's smart contract lies in the so-called loopholes, that is, security issues. According to relevant research, 34200 (about 3%) of the nearly 1 million smart contracts based on Ethereum contain security vulnerabilities, which will allow hackers to steal eth, freeze assets or delete contracts, such as the infamous Dao incident

(1) what does Dao mean

before introcing the Dao event, let's first introce what Dao is. Dao is the abbreviation of decentralized

autonomous organization, which can be understood as decentralized autonomous organization. From the perspective of Ethereum, Dao is a kind of contract or a combination of contracts on the blockchain, which is used to replace the government's review and complex intermediate proceres, so as to achieve an efficient and decentralized trust system. Therefore, Dao is not a specific organization, that is to say, there can be many Dao, all kinds of Dao

(2) the infamous Dao event

however, when we talk about Dao now, we basically refer to the Dao event, that is, the infamous hacker attack event we just mentioned. As we know, the English word "the" refers to "the Dao event". The Dao event

refers to "the Dao event", because we just said that Dao is not a specific organization, there can be many Dao, all kinds of Dao

in 2016, slock.it, a German company focusing on "smart locks", launched the Dao project on Ethereum in order to realize decentralized physical exchange (such as apartments and ships). Since April 30, 2016, the financing window has been open for 28 days

unexpectedly, this Dao project is very popular. It raised more than US $100 million in just half a month. By the end of the whole financing period, it raised a total of US $150 million. Therefore, it has become the largest crowdfunding project in history. However, it didn't last long. In June, hackers took advantage of the loopholes in the smart contract to successfully transfer more than 3.6 million Ethernet coins and put them into a Dao sub organization, which has the same structure as the Dao. At that time, the price of Ethernet currency fell directly from more than $20 to less than $13

this event shows that there are loopholes in smart contracts, and once the loopholes are exploited by hackers, the consequences will be very serious. This is why many people criticize Ethereum and say that its smart contract is not smart

to solve this problem, many foreign companies begin to provide code audit services in order to solve the vulnerability problem of smart contract. From a technical point of view, some teams are currently testing smart contracts. Most of these teams are led by professors from Harvard, Stanford and Yale, and some of them have obtained investment from leading institutions

in addition to the problems of insufficient expansibility and loopholes in smart contracts, the controversy over Ethereum lies in the POS consensus mechanism it pursues, that is, the proof of equity mechanism. Under the proof of equity mechanism, if anyone holds more money and holds it for a longer time, he will get more "rights" (interests) and have the opportunity to get bookkeeping power, Bookkeeping can also be rewarded. In this way, it is easy to create the oligarchic advantage of "the stronger the stronger"

Another problem is the chaos of ICO. ICO is a common way to raise funds for blockchain projects, which we can understand as pre-sale. The outbreak of ICO projects on Ethereum has caused illegal activities such as fund allocation and money fraud under the banner of ICO, which has caused security risks to social and financial stability

2. 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.

4. Ethernet clown is a real blockchain pet development game
cryptoclones is a digital blockchain game with collection value based on Ethereum blockchain. Using ether money to adopt clowns can be resold, and they can also be used to breed a new generation of clowns with strange shapes. They can also be cultivated to work and earn money, which makes the digital collection of clowns more sustainable and playable
the blockchain pet was originally caused by the fire of crypto kitties. It is the first digital game based on blockchain Technology launched by Ethereum. Each pet is unique and cannot be copied in the world. It is understood that Chuangshi cat was even fired to tens of millions of dollars
as a blockchain pet with great sustainability and playability, the future development prospect of ether clown can not be underestimated!

5. The dragon is a mythical creature typically depicted as a large and powerful serpent or other reptile, with magical or spiritual qualities. Mythological creatures possessing some or most of the characteristics typically associated with dragons are common throughout the world's cultures.

Dragons are commonly portrayed as serpentine or reptilian, hatching from eggs and possessing long, typically scaly, bodies; they are sometimes portrayed as having large eyes, a feature that is the origin for the word for dragon in many cultures, and are often (but not always) portrayed with wings and a fiery breath. Some dragons do not have wings at all, but look more like long snakes.

Although dragons (or dragon-like creatures) occur commonly in legends around the world, different cultures have perceived them differently. Chinese dragons (Simplified Chinese: 龙; Traditional Chinese: 龙; pinyin: lóng), and Eastern dragons generally, are usually seen as benevolent, whereas European dragons are usually malevolent (there are of course exceptions to these rules). Malevolent dragons also occur in Persian mythology (see A Dahaka) and other cultures.

Dragons are often held to have major spiritual significance in various religions and cultures around the world. In many Eastern and Native American cultures dragons were, and in some cultures still are, revered as representative of the primal forces of nature and the universe. They are associated with wisdom—often said to be wiser than humans—and longevity. They are commonly said to possess some form of magic or other supernormal power, and are often associated with wells, rain, and rivers. In some cultures, they are said to be capable of human speech.

Dragons are very popular characters in fantasy literature, role-playing games and video games today.

The term dragoon, for infantry that move around by horse, yet still fight as foot soldiers, is derived from their early firearm, the "dragon", a wide-bore musket that spat flame when it fired, and was thus named for the mythical beast.

[edit] Symbolism
In medieval symbolism, dragons were often symbolic of apostasy and treachery, but also of anger and envy, and eventually symbolised great calamity. Several heads were symbolic of decadence and oppression, and also of heresy. They also served as symbols for independence, leadership and strength. Many dragons also represent wisdom; slaying a dragon not only gave access to its treasure hoard, but meant the hero had bested the most cunning of all creatures. In some cultures, especially Chinese, or around the Himalayas, dragons are considered to represent good luck.

Joseph Campbell in the The Power of Myth viewed the dragon as a symbol of divinity or transcendence because it represents the unity of Heaven and Earth by combining the serpent form (earthbound) with the bat/bird form (airborne).

Dragons embody both male and female traits as in the example from Aboriginal myth that raises baby humans to althood training them for survival in the world (Littleton, 2002, p. 646). Another contrast in the way dragons are portrayed is their ability to breathe fire but live in the ocean--water and fire together. And like in the quote from Joseph Campbell above, they also include the opposing elements of earth and sky. Dragons represent the joining of the opposing forces of the cosmos.

Yet another symbolic view of dragons is the Ouroborus, or the dragon encircling and eating its own tail. When shaped like this the dragon becomes a symbol of eternity, natural cycles, and completion.

[edit] In Christianity
The Latin word for a dragon, draco (genitive: draconis), actually means snake or serpent, emphasizing the European association of dragons with snakes. The Medieval Biblical interpretation of the Devil being associated with the serpent who tempted Adam and Eve, thus gave a snake-like dragon connotations of evil. Generally speaking, Biblical literature itself did not portray this association (save for the Book of Revelation, whose treatment of dragons is detailed below). The demonic opponents of God, Christ, or good Christians have commonly been portrayed as reptilian or chimeric.

In the Book of Job Chapter 41, the sea monster Leviathan, which has some dragon-like characteristics.

In Revelation 12:3, an enormous red beast with seven heads is described, whose tail sweeps one third of the stars from heaven down to earth (held to be symbolic of the fall of the angels, though not commonly held among biblical scholars). In most translations, the word "dragon" is used to describe the beast, since in the original Greek the word used is drakon (δράκον).

In iconography, some Catholic saints are depicted in the act of killing a dragon. This is one of the common aspects of Saint George in Egyptian Coptic iconography [1], on the coat of arms of Moscow, and in English and Catalan legend. In Italy, Saint Mercurialis, first bishop of the city of Forlì, is also depicted slaying a dragon.[2] Saint Julian of Le Mans, Saint Veran, Saint Crescentinus, and Saint Leonard of Noblac were also venerated as dragon-slayers.

However, some say that dragons were good, before they fell, as humans did. Also contributing to the good dragon argument in Christianity is the fact that, if they did exist, they were created as were any other creature, as seen in Dragons In Our Midst, a contemporary Christian book series by author Bryan Davis.

[edit] Chinese zodiac
The years 1916, 1928, 1940, 1952, 1964, 1976, 1988, 2000, 2012, 2024, 2036, 2048, 2060 are considered the Year of the Dragon in the Chinese zodiac.

The Chinese zodiac purports that people born in the Year of the Dragon are healthy, energetic, excitable, short-tempered, and stubborn. They are also supposedly honest, sensitive, brave, and inspire confidence and trust. The Chinese zodiac purports that Dragon people are the most eccentric of any in the eastern zodiac. They supposedly neither borrow money nor make flowery speeches, but tend to be soft-hearted which sometimes gives others an advantage over them. They are purported to be compatible with Rats, Snakes, Monkeys, and Roosters.

[edit] In East Asia
Main article: Chinese dragon
Main article: Vietnamese dragon
Dragons are commonly symbols of good luck/health in some parts of Asia, and are also sometimes worshipped. Asian dragons are considered as mythical rulers of weather, specifically rain and water, and are usually depicted as the guardians of flaming pearls.

In China, as well as in Japan and Korea, the Azure Dragon is one of the Four Symbols of the Chinese constellation, representing spring (season), the element of Wood and the east. Chinese dragons are often shown with large pearls in their grasp, though some say that it is really the dragon's egg. The chinese believed that the dragons lived under water most of the time, and would sometimes offer rice as a gift to the dragons. The dragons were not shown with wings like the European dragons because it was believed they could fly using magic.

A Yellow dragon (Huang long) with five claws on each foot, on the other hand, symbolize imperial authority in China, and indirectly the Chinese people as well. Chinese people often use the term "Descendants of the Dragon" as a sign of ethnic identity. The dragon is also the symbol of royalty in Bhutan (whose sovereign is known as Druk Gyalpo, or Dragon King).

In Vietnam, the dragon (Vietnamese: rồng) is the most important and sacred symbol. According to the ancient creation myth of the Kinh people, all Vietnamese people are descended from dragons through Lạc Long Quân, who married Âu Cơ, a fairy. The eldest of their 100 sons founded the first dynasty of Hùng Vương Emperors.

A naga guarding the Temple of Wat Sisaket in Viang Chan, LaosWhere the original concept of a dragon came from is unknown, as there is no accepted scientific theory or any evidence to support that dragons actually exist or have existed.

Some believe that the dragon may have had a real-life counterpart from which the legends around the world arose — typically dinosaurs or other archosaurs are mentioned as a possibility — but there is no physical evidence to support this claim, only alleged sightings collected by cryptozoologists. In a common variation of this hypothesis, giant lizards such as Megalania are substituted for the living dinosaurs. Some Creationists hold that dragons are just an exaggerated depiction of what we now call dinosaurs and that humans and dinosaurs (dragons) did co-exist.[1] All of these hypotheses are widely considered to be pseudoscience or myth.

Dinosaur fossils were once thought of as "dragon bones" — a discovery in 300 BC in Wucheng, Sichuan, China, was labeled as such by Chang Qu.[2] It is unlikely, however, that these finds alone prompted the legends of flying monsters, but may have served to reinforce them.

Herodotus, often called the "father of history", visited Judea c.450 BC and wrote that he heard of caged dragons in nearby Arabia, near Petra, Jordan. Curious, he travelled to the area and found many skeletal remains of serpents and mentioned reports of flying serpents flying from Arabia into Egypt but being fought off by Ibises Histories.

According to Marco Polo's journals, Polo was walking through Anatolia into Persia and came upon real live flying

6. How to earn money by raising cats
on cryptokitties, you can buy virtual cats. By 17:00 Beijing time on December 6, 2017, the cheapest kitten had reached 0.037eth. Equivalent to 110 yuan per piece
then the kittens have some opinions about the generation. For example, Gen 12 indicates that it is the 12th generation, while Gen 20 indicates that it is the 20th generation. Generally speaking, the smaller the algebra, the more valuable it is. And you can make your kittens slap each other. For example, a Gen 1 kitten and a Gen 1 kitten will give birth to a Gen 2 kitten
you can sell your kittens and their offspring for money
but what if you don't have two kittens? If you only buy one kitten, you can use your kitten to have fun with other people's high-quality kittens. The fee also depends on the kittens (to be honest, this mechanism is very evil, similar to... Borrowing chickens to have children?) The quality of the proct. If your kitten is of high quality, you can also use your kitten to mate other people's kittens, and then you get Ethereum income
but kittens also have special fertility rates

every time a kitten gives birth to one generation, it will have a certain cooling time, and it can't regenerate kittens within the cooling time,
the cooling time is divided into several grades
fast: 1 minute
swift: 2 – 5 minutes
snappy: 10 – 30 minutes
brisk: 1 – 2 minutes
plodding: 4 – 8 minutes
slow: 16 – 24 minutes
sluggi Sh (lazy kitten): 2 – 4 days
catatonic (nervous kitten): 1 week
so the price of your cat also depends on its birth time
and generally speaking, the larger the algebra is, the higher the gen value is, and the slower their growth rate is
but I want to make complaints about it because CryptoKitties is too hot! Ethereum network has a little bit of a crash, the official recommended that every time you buy a cat, the minimum handling charge is 21000. 400000 fuel = 0.01eth. However, it is irritating that I raised the procere to 1.6 million fuel, which is 0.04, and Ethereum still failed. 0.04 Ethereum. That's more than 120 yuan. It's too dark.

8.

Now many people have played the game of keeping electronic pets. Now there is a new kind of electronic pet game, which is completely different from the past. Although this "cat" is not a real "cat", but a small game called cryptokitties, which is based on Ethereum's "encrypted cat", also known as "cloud cat", its popularity is absolutely no less than that of any valuable real cat

one sold for 120000 US dollars, and 70000 were traded in less than two weeks after it was launched.

the online edition of the Sunday Times reported on the 10th that since the game was launched 12 days ago, 70000 encrypted cats have been traded, with a transaction volume of more than 11 million US dollars, about 72.82 million yuan

The phenomenon of

news pictures

has caused many discussions. There is a view that this kind of electronic pet is not the first time to appear. This time it only carries the concept of "block chain". Such a high price is just a bubble. p>

there are also views that, in a sense, this game is the first large-scale application of blockchain in daily scenes. Blockchain ensures the irreplaceability of each cat and may have collection value

9. Me too. Have you solved your problem? How did you do that

10. It is a real blockchain pet development game, which is more playable than the previous ethercats. Using ether money to adopt clowns can be resold, and they can also be used to breed a new generation of clowns with strange shapes. They can also be cultivated to work and earn money, which makes the digital collection of clowns more sustainable and playable.
