just like bitcoin, Ethereum is neither controlled nor owned by anyone - it is an open source project created by many people around the world. Different from bitcoin protocol, Ethereum's design is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform. With the release of homestead, anyone can use the applications on this platform safely
Ethereum is a programmable blockchain. It does not give users a series of preset operations, but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator.
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
It does not belong to MLM
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through crowdfunding in 2014. The market value of Ethernet currency is second only to bitcoin, and it is the second largest encrypted digital currency in the world
extended data
bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years. In fact, bitcoin's blockchain is a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network
however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions
In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoinnow bitcoin bubble serious, may collapse, the market needs to be cautious. But unlike tulip, it will rise slowly after falling, rather than collapse
because the total amount of bitcoin is limited. mining costs are getting higher and higher. It can also be preserved for a long time at a low cost. At the same time, about 40% of bitcoin is in the hands of a very small number of people, which can achieve high control
you need to judge its future & quot; Collection value & quot; Up or down
what you should pay attention to is its & lt; Collection value & quot; It does not depend on itself, but on the public's enthusiasm for it and its general recognition. It's changing all the time
from the perspective of coin holders, the more people they buy, the better. This will lead to the & lt; decline of bitcoin; Collection value & quot; Up
there are many coin holders who strongly advocate bitcoin and turn shit into gold. With the success of advocacy, more and more people buy money. Excrement really becomes gold. Advocacy is no longer advocacy, but truth. This paradox is also what Soros said; Reflexivity Principle & quot; It's the embodiment of the idea. This is also the most painful and unacceptable thing for rational people who do not speculate
at present, I personally feel that the price is too high. There are too many speculators in the short term. There are some bubbles. Investment should be cautious. You can buy some in the next slump and collect them for a long time
you should not believe the following two statements:
1. Bitcoin is the perfect currency in circulation in the future. It has high use value, so it is very valuable
2. Bitcoin is deceptive and has no use value, so it is not valuable
one answer is that bitcoin is like a diamond. It does
diamond's & lt; Use value & quot Love is eternal), which was hyped by De Beers in the last century. Until then, diamonds were not worth money. And the total supply of diamonds is monopolized and controlled by giants such as De Beers Is "diamond" the most wonderful marketing scam in the world in the 20th century? Is it really worthless? There are many good answers to this question.)
De Beers constantly claims that diamonds are the strongest objects and can symbolize eternity. People graally accepted it
and Nakamoto develops bitcoin, and believes that its decentralization, blockchain technology and other characteristics are suitable for the future as a perfect e-currency (the initial title of the paper is "a peer-to-peer e-cash system"). With the expansion and publicity of bitcoin's followers, more and more people have accepted this idea. But now there are still a large number of people who don't know anything and feel that the price is rising sharply, so they buy bitcoin. After buying it, reverse rationalize it and persuade yourself to accept the concept that bitcoin is a perfect electronic currency
this is & lt; The community of imagination; The process of formation. The essence is similar. It doesn't matter whether these concepts are true or not. It's important: how many people do you trust. If more people believe in it, it will come true
In the end, diamond has become an extremely successful marketing case. The symbolic meaning of diamonds has been formed all over the world; The community of imagination;. Instead of collapsing like tulip, it has become a sustainable instryfrom the current trend, bitcoin is working in this direction. There is a public opinion game between advocates and bearers to see who has more power to influence the huge group of passers-by to identify or not to identify with bitcoin. Both sides exaggerate, saying that bitcoin is the Holy Grail of changing human society and that bitcoin is a Ponzi scheme. At present, because of the continuous rise (and it has doubled after several sharp falls), the advocates have the upper hand
hailimeda (25.99 + 0.89%, buy) has become a leading mobile information service and third-party payment provider in China through M & a linkage advantages, entered the first echelon of A-share mobile payment, and formed a unique mass data base, which is expected to become one of the earliest financial service companies to lay out blockchain in China. Although the company's answer to the market rumor that it is involved in the blockchain technology instry is "so far, it has not been included in the main business", it seems to be optimistic that the company is involved in this field according to the research reports of many securities companies
Hang Seng Electronics (62.30-0.73%, buy) is trying to establish a digital bill system based on alliance chain by using blockchain technology
on April 11, yingshisheng (44.20-2.60%, buy) said on the investor relations interactive platform that the company currently has technical reserves in this area, but it is in the initial stage
Feitian Chengxin (31.20 + 3.31%, buy) said that it has certain technical reserves and research in blockchain technology, and the company said that it will actively participate in digital currency and other blockchain technology instries in the future
Hengbao (14.85-0.07%, buy) has blockchain technology research reserves, focusing on information security and big data
New Guo (26.52-1.19%, buy) actively pays attention to blockchain technology, and established bitcoin research group in 2014
of course, these are just concept stocks. Bitcoin, Ethereum and decent are the real blockchain projects.
this will make the bitcoin market more full of bubbles, and speculators will be more than ever before. according to media reports, ring this period, the price of bitcoin broke through a record high again, reaching US $64000. The main driving force for further price rise is the official listing of the first digital currency exchange, and the shares of the exchange will rise sharply as soon as they are listed. This has completely aroused the sentiment of bitcoin investors. Retail investors have been pouring into the market and the price has been pushed up. Especially under the promotion of musk and other celebrities, many institutions also participated in it, and some enterprises began to change their reserve currencies into virtual currencies
