1.

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

    2. This should be a problem in two aspects: open source code refers to what we all know about this piece of code; As for the modification and destruction of the system, it should be the problem of system protection, so that people who want to modify and destroy can not enter. For example, there is a very valuable cultural relic in the glass window of a museum, which is on public exhibition. If you ask this question, someone will destroy or steal it.
    3.

    Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:

    1, open source code

    upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public

    2, complete decentralization

    anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"

    3. Developing decentralized applications

    through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers

    4. The public chain, as the name suggests, has great inclusiveness and fairness. The better the public chain project does in these two aspects, the more prominent it will be. At present, many public chains sacrifice fairness in order to speed up the transaction, which is not optimistic. There is a project called Fanta network. Their DSC technology claims to be safe, democratic and fair, which deserves long-term attention. However, their code will not be open source until the end of the year, and the progress needs to be accelerated

    6. When a simple project starts, it usually takes about one second. You can open the Tomcat directory to see if there is your project folder in webapp. If you use MyEclipse, the deployment is very simple. There is a deployment button on the left side of the server icon to add the project to the server
