What are the six types of Ethereum coins
a brief history of etheric Classics (etc)
etheric classics began with an unfortunate event
in May 2016, the decentralized autonomous organization (DAO) held a token sale with the goal of establishing a blockchain based venture capital to fund future decentralized applications (dapps) in the ethereum ecosystem
basically, Dao is a complex smart contract that operates in a decentralized way - computer code that automatically performs tasks between multiple parties when conditions are met
despite its ambitious goals and successful token sales, Dao's code has a major vulnerability that allows attackers to steal eth from decentralized organizations
the attacker took advantage of this vulnerability in June 2016, triggering the infamous Dao hacking event, and maliciously stole eth worth about US $50 million
there is no doubt that Dao hacking has shocked Ethereum community and made eth price drop from $20 to $13
after the Dao hacking, the Ethereum community has to choose from three options
< UL >do nothing and try to bear the consequences of the attack
start soft bifurcation to recover funds
deploy a hard fork to recover the lost eth
both soft and hard bifurcations are significant network upgrades. However, soft fork allows users who are not upgraded to communicate with upgraded users, while hard fork is not backward compatible with previous versions
as developers realize that deploying soft forks will expose the network to distributed denial of service (DDoS) attacks, Ethereum community decides to initiate hard forks to recover the funds lost in Dao hacking attacks
although this scheme is supported by most people, a small number of people in Ethereum community oppose it. They think that "code is the law" and blockchain network should be unchangeable
the failure of both sides to reach an agreement on the solution eventually led to the fragmentation of Ethereum blockchain
those who tried to recover the lost eth chose the hard fork and opened the Ethereum (ETH) blockchain as we know it today, while another group stayed on the original Ethereum classic (etc) chain
what problems does ethereal classic solve Ethernet classic (etc) is a blockchain platform that allows developers to deploy smart contracts and dapps although this function is the same as Ethereum (ETH), etc blockchain has two main differences first of all, Ethereum classic community opposes tampering with distributed ledger and supports the view that "blockchain network cannot and should not be modified" secondly, although there is no rigid upper limit on the total supply of eth, it is allowed to create 230 million etc at most by adopting the monetary policy of constant supply as a bonus item, ethereal classic launched Atlantis hard bifurcation last year to increase the interaction with Ethereum and improve the privacy protection of transactions through ZK snarks the trading platforms recommended by ethereal classic etc are: Fire coin, okex, AAX, etc
Q: What is bitcoin bifurcation and why
A: the reason why bitcoin bifurcates is that the underlying technology of bitcoin is blockchain. Some people begin to think that bitcoin's block capacity is too small and there are always congestion. So they ask for bitcoin's upgrade and expansion. Some people think that bitcoin's function is too single and its future development is not optimistic, So these people ask bitcoin to have the function of building DAPP (decentralized application), and some support it, while others oppose it. This kind of divergence can be understood as the bifurcation of bitcoin
Q: the classification of bitcoin bifurcation
A: there are two kinds of bifurcations of bitcoin, one is soft bifurcations, the other is hard bifurcations, so what is soft bifurcations
Q: the formation principle of soft bifurcation
A: soft fork refers to optimizing and modifying bugs in the original bitcoin network to improve the capacity of the block, such as 2m, 4m or 8m, 16m. The segwit lightning network is the mainstream solution, which is equivalent to a traffic jam on the main road, and the development team will build an auxiliary road to help the main road to divert congestion
this is a mild solution, which can make the original bitcoin network compatible with the network after soft bifurcation, and the main transaction of bitcoin is still on the main chain
Q: disadvantages of soft bifurcation
A: of course, there are disadvantages of soft bifurcation, that is, it can only solve the temporary congestion problem, and after the implementation of soft bifurcation, it can only keep the network unobstructed for a few years. In the future, it needs continuous expansion, which has an impact on the stability of the system
Q: what is hard bifurcation and its formation principle
A: another solution is hard fork, which means to upgrade the bitcoin system again, change the height of the block completely in the form of code, and take bitcoin unlimited as the mainstream solution. Generally speaking, it is equivalent to a traffic jam on the main road. We directly abandon this road and find a place to build a three-dimensional transportation hub on the ground and underground. All new cars use this transportation system, which changes the block size of the bitcoin network and optimizes the processing speed of the network
Q: what are the disadvantages of hard bifurcation
A: but hard bifurcations also have disadvantages, that is, they are not compatible with the original bitcoin system, which requires all people in the bitcoin network to support hard bifurcations. If some people do not support hard bifurcations, there will be two versions of bitcoin network, which will proce two bitcoins. The blockchains of the two bitcoins form a competitive relationship, This kind of internal friction will lead to greater price volatility and uncertainty of bitcoin's future situation
Q: a classic case of bitcoin bifurcation
A: Eth and etc are typical cases of hard bifurcation. The Dao project is a crowdfunding project initiated by slock.it, a blockchain Internet of things company. It was officially released in May 2016. As of June of that year, the Dao project has raised more than $160 million. It wasn't long before the Dao project was targeted by hackers. Because of the huge loopholes in the smart contract, the Dao project was transferred to ether coin with a market value of 50 million US dollars
in order to recover the assets of many investors and stop the panic, vitalik buterin, the founder of Ethereum, finally proposed the idea of hard bifurcation, and finally completed the hard bifurcation in block 1920000 of Ethereum through a majority vote of the community, rolling back all the Ethereum coins occupied by hackers
even though Ethereum hard bifurcates into two chains, some people who believe in the tamper proof property of blockchain still stay on the original chain of Ethereum classic. Today, Ethereum (ETH) and Ethereum classic (etc) are ranked in the top 20 in the global cryptocurrency market value, which is one of the reasons why they are regarded as classic cases in the field of hard bifurcations
Q: the difference and influence between soft bifurcation and hard bifurcation
A: for users, soft forking will not proce new bitcoin currency. They only need to understand the transaction mode and K-line characteristics of bitcoin. They only need a mainstream wallet of bitcoin
hard bifurcation will generate new currencies, and there may be more than one new currency. Once the core code of bitcoin is modified and the core code of bitcoin is reconstructed, there may be a second time for the first time, and btc1 and btc23456789 may all happen. Users will be confused. Which kind of coin would be better for me to trade? What kind of bitcoin do I use to pay for a large circulation range? In short, users with dyschooia will crash. Moreover, users need to download wallets of different hard bifurcated systems, which brings complex operation to save and pay bitcoin
however, correspondingly, the user's right to choose has also increased. You can choose the bitcoin code developed by the development team you like and trust. When the bifurcations of bitcoin are not clear, when the soft bifurcations start to activate and the computing power starts to vote, the best way for users to deal with it is to wait and see. Don't recharge and extract bitcoin in the process of bifurcation
in addition, soft fork will change the settlement mode of bitcoin all nodes, and some small settlement will be confirmed by the third party node, namely settlement channel. The settlement channel may incur part of the service charge. Similar to the role and business model of UnionPay
what is bitcoin bifurcation? The difference and influence of soft bifurcation and hard bifurcation
The capacity of a block in bitcoin is 1m (megabytes). A transaction is between 250 and 500 bytes
according to this algorithm, a block contains about 4194.3 transactions
the confirmation time of a block in bitcoin is 10 minutes, so the seven transactions that a block can process per second may sometimes be less than seven
What are the consequences The bifurcations of
bitcoin are divided into hard bifurcations and soft bifurcations
hard fork means that when the block format or transaction format of bitcoin changes, the UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes
the upgraded nodes can verify the blocks proced by the non upgraded nodes, and they continue the chain they think is correct, so they are divided into two chains
What is soft bifurcationsoft bifurcation means that when the data structure of bitcoin transaction changes,
UN upgraded nodes can verify the blocks proced by upgraded nodes,
and upgraded nodes can also verify the blocks proced by UN upgraded nodes
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.
bifurcation means an incomplete upgrade of bitcoin. After upgrading, some UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes, but the upgraded nodes can verify the blocks proced by the UN upgraded nodes, thus splitting the two chains
now there is a flood of counterfeit coins in the market, which are actually some bifurcated coins
a typical split coin operation is to announce a split coin and give each user a special new "split coin" or "candy" in a ratio of 1:1
after users generally get the new currency after the split, there will be a natural demand for trading. At this time, public opinion can be guided, and the huge number of users and trading demand force the exchange to put on the currency
after the currency is put on the exchange, the holders of the forked currency first use a certain amount of capital to pull up the forked currency, create the illusion of pursuing, and then sell their "pre g" forked currency for arbitrage
however, players can also think that some forked coins are valuable, so they can follow up. Therefore, the exchange of forked coins is also valuable. There are still many such activities, such as bitfinx, coin rise, coin safety, etc.
after Ethereum bifurcates into etheric fog, the two will exist and develop together< br />
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.
buy at a low price and sell at a high price
it's very easy to get the business running task. There is no qualification requirement. As long as there is a gang, you can get it from the sect master. After receiving the task, a silver note will appear in your backpack, which is the principal of your business! How to do a good job in business is the next thing you need to consider. It's worth noting that at this time you will enter a state of being unable to transmit, and everything will be done step by step with your legs
here's a reminder to all players: at this time, your name has become "XX Gang businessman". This is to tell you that you are doing business for the gang, and no one is allowed to disturb you. However, be careful. Some young swordsmen with bandit temper like to rob businessmen. Although they will lose their popularity, their gangs will increase the money of the corresponding banknotes and commodities. This is a business that can make no loss. So don't expect other young Xia to give up robbing you for fear of popularity. In the process of running a business, you must take good weapons and be ready to accept challenges at any time. Only with strong strength and courage can you defend the glory of the gang
selective buying and selling
there are four kinds of goods for us to buy from the specialty merchants in Chang'an city. The purchase price and selling price of each kind of goods are different. In order to save time and complete the business as quickly as possible, players should use their brains here to selectively purchase several kinds of goods according to the income and earn the maximum price difference
the next step is to run back and forth between several maps with specialty goods suppliers. The purchase prices of different goods vary in different locations. At present, there are two main business routes, one is from Chang'an city to Taohuawu and then to Loulan, the other is from Chang'an city to Kunlun mountain to Wangxian town. Find out your favorite business route and make the most profit for the gang
it's hard to run a business, but the target amount is not enough. Remember to go back to the gang and hand over the task to the master before it's really over. You will be rewarded with money, experience and tribute when you finish running business. You also have the chance to get all kinds of treasures in the gang warehouse!
