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

    The strict definition of blockchain refers to the distributed database technology that multiple nodes in peer-to-peer network jointly maintain a continuously growing list ledger constructed by time stamp and orderly record data blocks through consensus mechanism based on cryptography technology. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true

    blockchain is a technical solution similar to NoSQL (non relational database). It is not a specific technology, and can be implemented through many programming languages and architectures. There are many ways to realize blockchain, including pow (proof of work), POS (proof of stake), dpos (delegate proof of stake), etc

    the concept of blockchain was first proposed in the paper "bitcoin: a peer-to-peer electronic cash system" by indivials (or groups) who call themselves Satoshi Nakamoto. Therefore, bitcoin can be regarded as the first application of blockchain in the field of financial payment

    < H2 > [popular explanation]

    no matter how big the system or how small the website is, there is a database behind it. So who will maintain this database? In general, who is responsible for the operation of the network or system, then who is responsible for the maintenance. If it is wechat database, it must be maintained by Tencent team, and Taobao database is maintained by Alibaba team. We must think that this way is natural, but blockchain technology is not

    if we think of the database as a book, for example, Alipay is a typical account book. Any change of data is bookkeeping. We can think of database maintenance as a very simple way of accounting. In the world of blockchain, everyone in the blockchain system has the opportunity to participate in bookkeeping. The system will select the fastest and best bookkeeper in a period of time, maybe within ten seconds or ten minutes. The bookkeeper will record the changes of the database and the account book in a block. We can think of this block as a page. After the system confirms that the records are correct, the system will record the changes of the database and the account book in a block, It will link the fingerprint of the past account book to this paper, and then send this paper to everyone else in the whole system. Then, over and over again, the system will look for the next person with fast and good bookkeeping, and everyone else in the system will get a of the whole ledger. This means that everyone as like as two peas in the system is called Blockchain. It is also called distributed account technology. P>

    as like as two peas (computer) have identical accounting books, and everyone has the same rights, they will not collapse e to the loss of contact or downtime of a single person. As like as two peas, the data is transparent and everyone can see what changes are in every account. Its very interesting feature is that the data can't be tampered with. Because the system will automatically compare, it will think that the same number of books with the largest number are real books, and a small number of books with different numbers are false books. In this case, it's meaningless for anyone to tamper with his own account book, because unless you can tamper with most nodes in the whole system. If there are only five or ten nodes in the whole system, it may be easy to do so. However, if there are tens of thousands or even hundreds of thousands of nodes and they are distributed in any corner of the Internet, unless someone can control most computers in the world, it is unlikely to tamper with such a large block chain

    < H2 > [elements]

    combined with the definition of blockchain, we think that we must have the following four elements to be called public blockchain technology. If we only have the first three elements, we will consider it as private blockchain Technology (private chain)

    1, peer-to-peer network (power equivalence, physical point-to-point connection)

    2, verifiable data structure (verifiable PKC system, non tampering database)

    3, distributed consensus mechanism (Solving Byzantine general problem, solving double payment)

    4 Game design of Nash equilibrium (cooperation is the strategy of evolutionary stability)


    < H2 > [Characteristics]

    combined with the definition of blockchain, blockchain will realize four main characteristics: decentralized, trustless, collective maintenance and reliable database. And the other two will be derived from the four characteristics  Features: open source  Privacy. If a system does not have these characteristics, it can not be regarded as an application based on blockchain technology

    Decentralized: there is no centralized hardware or management organization in the whole network. The rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system. Therefore, it can also be considered that the blockchain system has excellent robustness

    trustworthiness: there is no need to trust each other when participating in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are also open. Therefore, within the specified rule range and time range of the system, nodes cannot and cannot cheat other nodes

    collective maintenance: the data blocks in the system are maintained by all the nodes with maintenance function in the whole system, and these nodes with maintenance function can be participated by anyone

    reliable database: the whole system will enable each participating node to obtain a of the complete database in the form of sub databases. Unless more than 51% of the nodes in the whole system can be controlled at the same time, the modification of the database on a single node is invalid, and the data content on other nodes cannot be affected. Therefore, the more nodes and computing power in the system, the higher the data security in the system

    Open Source: since the operation rules of the whole system must be open and transparent, the whole system must be open source for the program

    Privacy Protection: since there is no need to trust each other between nodes, there is no need to disclose the identity between nodes, and the privacy of each participating node in the system is protected

    3. Just like MLM, clearing inventory is just a cover, increasing value every day, that is, in order to stimulate everyone to buy his counterfeit money with real money, and only can't get in and out! The boss asked a bunch of stupid people to pay for his counterfeit money to buy things. Anyway, the boss only made money but didn't pay for it. As long as he made the game bigger, the more people involved, the more people who bought his money with real money. Because he stipulated that the counterfeit money would increase in value every day, so the believers hoped to hold more counterfeit money. But remember, when you want to cash in the counterfeit money, it's impossible, They can only pay transactions in the small areas cultivated by their cheater team. Frankly speaking, it is the cheater team that makes money. The earlier participants may get some goods because of value-added, which is doomed, but the vast majority of people need to contribute. The boss only made as like as two peas. He only earned money. His only risk was that he was afraid of being caught by the police. He could only buy small area officials, so sooner or later he would seize it. Then all the counterfeit money on the hands of the participants disappeared instantly, which was exactly the same as pyramid schemes.
    4. With the development of ATT today, I think the government has made some efforts, so there is no way for att to develop
    5. 1、 Several circles of blockchain
    currency circle: refers to the people who focus on currency speculation or even issue their own digital currency to raise funds. Generally speaking, blockchain project parties, exchanges and some blockchain media all belong to the currency circle
    chain circle: refers to people who focus on the research and development, application or underlying protocol of blockchain. Without the technical support of the chain circle, the coin circle can not exist. In the future, the implementation of the blockchain scene will depend on the technology of the chain circle
    mining circle: refers to the "miners" who focus on "mining"< Second, several investment behaviors of blockchain
    currency speculation: similar to stock speculation, refers to the behavior of repeatedly buying and selling digital currency through trading platform in order to obtain high income
    Soha: it's a transliteration of show hand, originally a term used in gambling games. It's the act of withdrawing all available chips at one time. When it comes to blockchain investment, it refers to investing all of your available assets in digital currency in order to speculate in money, which has the meaning of "bet your fortune"
    Buddhist holding of cryptocurrency: it refers to the behavior of not caring about the price trend of cryptocurrency after holding of cryptocurrency. No matter how much the asset price of cryptocurrency falls, it will not rece the holding of cryptocurrency in hand
    3. Segmentation of blockchain investors
    banker: refers to the investor with strong capital volume, strong relationship network and the most informed information, who can influence or determine the price trend of a certain currency to a large extent
    large investors: investors with abundant capital, but not as strong capital and relationship network as makers
    retail investors: refers to the small amount of funds, small amount of trading, and unorganized investors< Four, blockchain investment common phenomenon
    leek: is an image of metaphor, leek growth ability and adaptability are very strong, can be one after another in a large range of breeding. It is compared to some retail investors who do not know the market situation. Most of them are easily influenced by the investment sentiment. They buy at a high price and sell at a low price. Some people will lose money, and after they leave the market, new forces will enter. Like leeks, they will cut one crop and grow another soon
    cut leek: it means that the dealer buys at a low price, speculates at a high currency price, sells at a high price after the retail investors come in and make a profit, and then smashes the plate to a low position. In this way, the retail investors will suffer losses and the dealer will make a profit. The makers and the big investors keep repeating this routine, that is, "cutting leeks", while the retail investors keep entering, the makers repeat the routine of cutting leeks
    cut back: refers to the sharp drop in the price of digital currency, which is very huge, falling to half of the previous highest price. For example, when I buy a currency, the highest price of this currency is $100. After a while, I fall to less than $50. It can be said that my currency has been cut off
    meat cutting: it refers to the behavior of selling stop loss in time when the price of digital currency falls in order to prevent the continuous decline from causing greater losses, so as to prevent greater losses in the future
    being held up: it means that I spend a high price to buy a currency. After a while, the currency falls, and I don't want to sell it and stop loss in time. Instead, I choose to wait to see if the price can rise again. The waiting process is "being held up". In this case, I can be said to be held up
    unwinding: it means that the purchased digital assets graally rise back after a round of sharp decline, and the price rising back exceeds the price when I bought them. At this time, I will not lose money when I sell these digital assets. This is unwinding
    airdrop candy: refers to the free distribution of a certain amount of digital currency to users in order to promote the blockchain project at the beginning of the project. These free digital currencies are called "candy" by users.

    Digital assets att refers to the non monetary assets owned or controlled by enterprises or indivials in the form of electronic data, which are held in daily activities for sale or in the process of proction

    the network accounting, office automation, electronic payment system platform in the network era make the current mode of proction have incomparable advantages compared with the traditional mode of proction, but in real life, they only rely on magnetic media and exist a series of codes. Although they are digital commodities, they reflect the nature of assets, so they are called digital assets att

    extended data:

    att features of digital assets:

    1. High price. Because these application software with special purpose is specially developed for a specific work, its cost is higher, and its price is not lower than the price of fixed assets

    (2) strong attachment. Application software must be supported by computer hardware and system software in order to play its role

    3. Strong interaction. Even the simplest application software also has some interactive functions, such as the error prompt to the operator, which is the most basic advantage of IT instry procts

    The quantity is infinite. Digital assets as assets are scarce (because not all enterprises or indivials can create digital assets), but its supply can be unlimited. However, tangible assets are always limited e to the limitation of property and storage space

    Cost decreasing. The proction cost of tangible assets is positively proportional to the proction quantity. Due to the unlimited output of digital procts, the development cost is allocated to the output according to the traditional financial accounting method, so the cost of digital procts is lower and lower with the continuous expansion of sales volume

    source: network digital assets
