Decentralization of etcis
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; Or
start soft bifurcation to recover funds; Or
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 etc hot money, okex, AAX, etc

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
bitcoin cash
bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)
the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"
BTC is bitcoin
LTC is lightcoin
eth is Ethereum
etc is Ethereum classic
cloud chain is the first risk protection platform in the world to guarantee the blockchain world. In the cloud insurance chain platform, each user can use CIC token to complete the whole risk hedging process of insurance, underwriting and automatic claim settlement. The cloud insurance chain guarantees the intelligent contract to realize the automation of claims settlement, at the same time to disintermediate the guarantee of the blockchain world, which greatly reces the trust cost and operation cost. On February 5, okex, the world's largest digital currency trading platform, announced the global launch of cloud insurance chain (CIC), and opened the trading markets of CIC / BTC, CIC / Eth and CIC / usdt.
the Internet of things (IOT) has been a hot topic in recent years. People in the instry have been using the term to describe the future from home automation to smart city planning for several years. Now many projects have adopted the Internet of things technology, which promotes the development of global informatization
As a new technology,etc has been applied in the Internet of things. ETC technology can enhance the sharing of information and value in the digital economy. Etc's smart contract can automatically transmit information and value under dynamic conditions, providing a customized business model for the Internet of things and machine payment network. Based on the flexible and intuitive intelligent contract programming platform and supported by etc, we can push the development of the Internet of animals to a high degree of globalization, good security and decentralization
As the development team of etc, etc dev team is also concerned about the application of etc in IOT. At present, the team has started to develop a friendly virtual machine for IOT to make it universal, independent and efficient. Therefore, etc development team will upgrade several protocols in 2018 to make it suitable for mobile devices and embedded devices. In order to better use IOT applications, etc community has formulated a development plan for cross chain operation function. Aiming at the rapid increase of transaction data in the field of Internet of things, the fragmentation technology and side chain technology are designed. Improve efficiency while ensuring safety. The above is not just a technical solution. The etc development team has formulated a specific schele to enable etc nodes to run on the most popular Internet of things operating system "raspberry pie" in 2018grayscale, an investment trust sponsor of etc, wrote in a paper entitled "into the ether with Ethereum classic" published in August this year: "we believe that etc will one day become the foundation of a globalized, secure and decentralized Internet of things (lot) The word "Internet of things" appears in this paper many times, which seems to be one of the main reasons why the author of this paper, Matthew Beck, supports etc. In this regard, Beck, based on his own research and calculation, concluded that etc is very suitable for processing machines in the future, so that machines can automatically trade data. He pointed out that if by 2025, etc can obtain 10% of the data traffic of Internet of things devices, then the price of each etc will increase tens of times
referring to the investment opportunities of etc, Beck wrote: "first of all, etc has storage properties similar to the value of precious metals and bitcoin, which makes it an inflation hedging tool suitable for long-term investment. Secondly, as a digital token to run etc smart contract, etc is a scarce commodity, which can provide power for the development of the Internet of things in globalization. "
the combination of etc and Internet of things can not only push the Internet of animals technology to a higher level, but also promote the development of etc. The combination of the two makes the Internet of things more secure and decentralized, and also makes it more independent and universal. At the same time, the project also gives play to the advantages of etc, so that the value of etc has been well reflected
at present, compared with eth, etc has less applications. However, ETH is not perfect either. The incident of congestion caused by cloud cat shows that eth is defective. Due to the rigorous attitude of etc team towards technology, the implementation of each proposal of etc has been fully demonstrated, and the advantages of later development are graally revealed. Moreover, etc continues to expand its own field, especially the application expansion in the field of Internet of things, pushing it to a new peak. It is believed that etc will become a decentralized and tamperable public infrastructure in the future
The experience and feeling of taking a mental health class
the experience and feeling of staying in a mental health class are more and more concerned by the social form, especially the mental health of college students, who are faced with more and more tongue tied events e to their mental health, Let's fully realize that it is imminent to solve the psychological problems of college students in time. As a modern college student, I think mental health is to have an optimistic attitude towards life and study; Have correct self subjective consciousness; They can control themselves and their emotions well; As well as students and harmonious relationship, a good integration in the collective; The first time I took a psychology class, I was very nervous. I thought I had to say what I thought in front of so many students. Later, I realized that everyone was very friendly and there was no need to worry. In the future, we should stand in the position of others or from the perspective of others to see things. We can't just think about ourselves and don't think about whether others are hurt. I am very happy, now I learned to transpose thinking, I have a fortune. Mental health class has benefited me a lot, I learned a lot of knowledge and truth. Let me feel and understand the value of love in the world, and learn to live with others. I know that when we encounter misunderstandings, we should think in another place, be tolerant to others, understand others, and speak our own things frankly. Bear a foot of calm, step back and talk. No matter how many people you are with, you should always be fair and treat them equally. You should not be close to one or two people, but be separated from others. In particular, you should not protect the people you love. In this case, it is bound to cause others' jealousy, and many disputes arise. Parents for their children, teachers for students, superiors for subordinates, brothers, sisters, classmates, colleagues, their center must guard against this kind of situation, experience "experience and feelings of mental health class". After a semester of psychological study, I learned some essentials of communication with people, whether with relatives or friends, we should control the essentials of communication, learn to transpose thinking, and treat people with a tolerant heart. Only in this way can we manage the relationship with relatives and friends wisely, and make my side less quarrels, more love and warmth. I will apply the knowledge learned in the classroom to my daily life, accept love and repay love. Let's take off by love! In psychology class, I learned a lot of knowledge and answered a lot of questions. I also felt my own shortcomings and decided to correct them. The teacher of psychology class is very attentive, and the way of teaching is also different. However, the teacher and we are not people of the same era, but we don't feel that no matter what generation gap exists between her and us, she can teach us how to stand in different positions to see things, and how to deal with the relationship with our parents, teachers, classmates and friends. I will treat everything reasonably according to the main points of the teacher's teaching, open my heart to communicate with others, and do not have a gap with others. Through the course of mental health class, I finally feel the value of life. I feel that I have to be filial to my parents and do what I can for them. I feel that we do our own things. We don't have to worry about our parents and let them worry about us. We also have to be considerate of the people around us and let everyone get considerate. As the saying goes, at home by parents, go out by friends, although we have not really entered the social form, but the teachers and students around us are just like our friends, we should be sincere in everything. Keep a sincere heart, say sincere words and do sincere things. What's wrong with you, you should admit it frankly, and don't use words to conceal it; When someone rebukes you, you should accept it with a humble and grateful heart. You should not be ashamed to refuse. There should be no false politeness when you are with others, but you should always be polite and behave in a moderate way, so that people can't find fault with your actions and behaviors. More love for talents can bring more love, more respect for talents can bring more respect, more tolerance for talents can bring more tolerance and more compassion for talents. What you send is what you come back from. The psychology class let me understand some truth, in life to be tolerant, learn and family and friends transposition thinking, understanding and understanding of others. More know how to understand parents, love their own parents. I hope more courses like this will be offered. Psychology class gives me a new life experience: I should always think for others and understand others; Return love with a grateful heart
students can pass this class as long as they write by themselves
