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

what is Ethereum:
Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. Blockchain technology is one of them
Ethereum platform can safely run any program users want
advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum
what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application
The design of Ethereum is very flexible and adaptable
Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields
blockchain applications of Ethereum
Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc
Ethereum has achieved more than 100 blockchain applications by many start-ups
Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged
the relationship between Ethereum and blockchain:
Ethereum is a programmable blockchain
Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes
in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
BTC bitcoin
bitcoin is the first distributed digital asset platform created. Since its launch in 2009, it has proven to be not only the most popular, but also the largest market capital value. In addition, it is also the most expensive, with a value of $10710 per coin on February 17, 2018. Bitcoin introces the first blockchain distributed ledger dedicated to recording all transactions, and gets rid of the function that users need a central authority to process or verify transactions
its goal is to provide a platform for users to conct cross-border transactions without any intermediary, which is what we call decentralization. The platform's largest money (BTC) supply is about 21 million. Of this figure, about 16.5 million have been mined and are now in circulation. It is mined all the time around the world to ensure the circulation of coins
Advantages:1. Its distributed system provides users with great freedom
2. High portability
This is a secure networkdisadvantages:
1
2. The user may lose the key
eth Ethereum
Ethereum is also a distributed platform, which was created by Network Programmer vitalik buterin in July 2015. Ethereum aims to enable users to create and deploy smart contracts. One of the main functions of smart contracts is to allow the creation of encrypted assets or tokens running on Ethereum networks. Ethereum token is used to purchase various functions such as cloud storage space. These tokens are stored in a digital wallet compatible with Ethereum blockchain
Ethereum's digital currency ether serves as the medium for executing smart contracts. At present, about 98 million ether coins have been mined and circulated, and the circulation supply increases by about 18 million every year. Ethernet coin is created to run on the Ethereum network. It can be used to compensate the participant nodes or transfer from one user to another
advantages:

The safety was very highdisadvantages: large circulation
< H2 > extended data:generation principle:
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique
in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. The number of the top word on a banknote owns the banknote. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
after completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
-
about the variability of blockchain
-
eth, if most people agree to modify the chain, that is, variability, then they can modify the blockchain records and contracts
-
etc, blockchain records and contracts can't be modified, that is, they can't be tampered with
-
here are the advantages and disadvantages of the two methods
The advantage of -
variability is that people can make timely changes to make the right decisions. Therefore, modifying the specification is more practical than finding loopholes
-
non modifiability means that no matter how smart people are at that time, it is impossible not to make mistakes. Therefore, when problems arise in this scheme, it is best to find and solve the loopholes through the existing legal framework
-
differences in development
-
eth, whether it is intentionally arranged or since its birth, the core decisions of blockchain are made by Ethereum foundation with the participation of the community and most of them are developed by it
-
etc, the decision-making of blockchain is mainly decided by the feedback of three loose, collaborative teams with community participation
-
in any case, anyone can put forward improvement suggestions for the two kinds of blockchains. This is the benefit of open source, and it is also very common. You will find that developers of the two chains communicate with each other through GitHub and reddit. I hope to improve the frequency of communication in order to achieve the common goal
-
about compatibility
-
at present, the two kinds of blockchains are compatible with each other. Contracts or applications written by eth can be applied on etc, and vice versa
-
eth, focusing on ewasm, is committed to providing a platform for more and more developers, while the issue of contract security is secondary, such as viper
-
etc focuses on making developers create more secure contracts, such as viper, iohk research, at the cost of consuming the number of potential developers
-
it's obvious that both chains can accept each other, regardless of whether their wishes are the same or not. My view is that the number of developers is not necessarily related to the quality of the proct
-
about the transaction speed
-
eth, the average is 25 seconds, which will be shortened after upgrading
-
etc, with an average time of 14 seconds, maintained at 10-14 seconds after upgrade, according to ecip-1010 and ecip-1036 protocols
-
about the block capacity
-
eth, with the daily trading volume of eth graally reaching 5 million, the block capacity is graally saturated. This situation is similar to the recent transaction cost of bitcoin. This problem can be solved by expanding the block capacity by increasing the default fuel limit
ETC， At present, there is still a lot of room for block capacity. As more and more people accept etc, the block capacity will also increase, just like eth
-
about community
-
eth, mainly discuss on reddit
-
etc, mainly discuss on slack
-
about monetary policy
-
eth, the planned supply is growing steadily, resulting in an average inflation of 3% in eth blockchain in its life cycle
-
etc, before 2025, inflation will reach 3%, and then the total supply will reach 200 million etc, and then there will be deflation
As for the regional distribution of trading volume, China accounts for 20%, South Korea 25% and the United States 25% In etc, China accounts for 50%, South Korea 25% and the United States 10% About securities, at present, investors do not have the option to trade securities. Recently, one of eth's ETFs, trading open-end index funds, was denied by the regulators -
etc owns etc trading trust, which allows investors to own etc instead of the asset itself
Ethereum Community Foundation (ECF) is a non-profit organization. Its original idea was to give community projects a bonus to support incubation of early projects and research. Then in 2018, omisego, Golem, status, maker, Web3 (Polkadot), cosmos and ef (Ethereum Fund) were set up in Tokyo as consultants
ECF 2.0 is the upgrade of ECF, which has two core goals:
< UL >
coordinate community relations through various harmonious ways, such as bonus, strategic and business support, and community activities
in order to become an open capital network, ECF emphasizes its initial vision, which is to form a network with various funds to realize the support and contribution to the community
In addition, ECF 2.0 upgrade will not only support non-profit infrastructure projects, ecation programs, instrial community activities, but also support application and tool development, and even commercial projects
although bitcoin and Ethernet are both digital currencies, unlike bitcoin, the main purpose of Ethernet is not to build itself as a payment substitute, but to facilitate and monetize the operation of Ethereum, so that developers can build and run distributed applications
The idea of Ethereum was born in 2013. Vitalik buterin ˙ When he was a programmer in the bitcoin community, he suggested to the core developers of bitcoin to develop a language for application developers to facilitate the development of various applications. Bitcoin core developers disagree. So God V decided to develop a new platform for this purpose
V God wrote the white paper of etheric currency in 2013, in which he explained the goal of building a decentralized program. In 2014, we got development funds through crowdfunding, so we developed the Ethernet system< (better digital currency trading platform "currency exchange")
since its birth, it has carried out four hard bifurcations so far
for the first time, in order to adjust the difficulty
released a stable version of "homeland" for the second time
for the fourth time, in order to prevent DDoS and rece weight
there is only the third hard fork, because of the hacker attack, and forced to fork. This is the Dao event
On July 30, 2015, v-god and Ethereum Foundation created the first smart contract platform and designed the Dao Ethereum contracton April 30, 2016, the Dao smart contract was officially deployed, and the world's largest crowdfunding was completed, reaching an amazing $150 million As an aside, the biggest crowdfunding event in time is EOS crowdfunding, which has reached an even more amazing $5 billion!)
on June 17, 2016, the Dao was attacked by hackers, who stole about 50 million US dollars of Ethernet currency, and the price also plummeted from US $20 to US $15, causing great harm to Ethereum. In order to recover the loss of investors, the community finally decided to hard fork
therefore, on July 20, 2016, at the block height of 1920000, the hard branching was successful, and the new chain is called Ethereum eth, while the original chain is now Ethereum classic etc
what is Ethereum
Ethereum is often compared with bitcoin, but the situation is different. Bitcoin is a kind of cryptocurrency and distributed payment network, which allows bitcoin to be transferred between users
related: what is bitcoin? How does it work
Ethereum has a bigger goal. As Ethereum says, "Ethereum is a distributed platform running smart contracts.". These smart contracts run on "Ethereum virtual machine", a distributed computing network composed of all devices running Ethernet nodes
"distributed platform" means that anyone can set up and run an Ethereum node just as anyone can run a bitcoin node. Anyone who wants to run "smart contracts" on nodes must pay the operators of these nodes in ether, which is a cryptocurrency related to Ethereum. Therefore, the person running the Ethernet node provides computing power and gets paid in the Ethernet, which is similar to the way that the person running the bitcoin node provides hash power and pays in bitcoin
in other words, although bitcoin is only a blockchain and payment network, Ethereum is a distributed computing network, and its blockchain can be used for many other things. Details are provided in the Ethereum white paper
what is ether
Ethernet is a digital token (or cryptocurrency) related to Ethereum blockchain. In other words, Ethereum is the token and Ethereum is the platform. But now people often use these terms alternately. For example, coinbase allows you to buy Ethereum, which stands for Ethereum
this is technically "altcoin", which actually means a non bitcoin cryptocurrency. Like bitcoin, ether is supported by distributed blockchain - in this case, Ethereum blockchain
developers who want to create applications or Ethereum smart contracts on Ethereum blockchain need Ethernet token to pay for nodes to host it, while users of Ethereum based applications may need Ethernet to pay for services in these applications. People can also sell services outside the Ethereum network and accept Ethernet payments, or they can sell Ethernet tokens in cash - just like bitcoin
