Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")
The token on theblockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin
extended data:
Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks
for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound
in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale
-
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
etc (Ethereum Classic) is a bifurcated currency that Ethereum hard bifurcates after 1920000 blocks, and its function is very similar to Ethereum. Etc adheres to the concept of decentralization and supports the consensus mechanism of blockchain guarantee. Etc firmly believes that once the blockchain starts to run, its development direction will not be controlled by any central team, but will be determined by the consensus of the people participating in the whole network and the consensus of the computing power of the whole network
the Ethereum blockchain hard branching in July 2016 aims to transfer the Dao funds stolen by hackers to an account controlled by investors, and let the old transaction records be forgotten by history. Most Ethereum developers are involved in the reversal, as are exchanges, startups and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old record. As a result, a small number of miners continued to use the original blockchain as a protest. They described the hard fork as a capital withdrawal for the abandoned project of the Dao. So Ethereum classic (etc) was born
2. Detailed parameters

developer: Ethereum Classic team core algorithm: ethash consensus proof: POW
release date: 2016 / 7 / 20 block time: About 15-17 seconds / block
total currency: fixed at 210 million, up to 230 million, Every 5 million blocks decelerate by 20%, and the first proction rection is expected to be in December 2017
main features: independent cryptocurrency
EOS coin
EOS (Chinese Name: EOS, English Name: EOS, abbreviation: EOS) is a token based on Ethereum released for eos.io blockchain system. Blockone is a new blockchain architecture developed by blockone company, which aims to expand the performance of distributed applications. The goal of EOS project is to achieve a blockchain architecture similar to the operating system supporting applications. The architecture can provide account, identity authentication, database, asynchronous communication and program scheling on hundreds of CPUs or clusters. The ultimate form of this technology is a blockchain architecture, which can support millions of transactions per second, and ordinary users do not need to pay for the use of the blockchain
function of EOS token
the current form of EOS cryptocurrency belongs to ERC 20 smart contract token on Ethereum blockchain. EOS ERC 20 token will be converted into the cryptocurrency available in EOS system 1:1 after the formal launch of EOS blockchain. The EOS system is expected to release the test network in August 2017, and it is expected to take one year for the main network of EOS blockchain to go online. The following application scenarios are introced after the EOS blockchain is officially launched
EOS cryptography currency has three main application scenarios: bandwidth and log storage (hard disk); Calculation and calculation reserve (CPU); State memory (RAM)
both instantaneous and long-term components consume bandwidth and computation. The blockchain system will maintain logs of all messages, which will be downloaded and stored by all complete nodes. With log information, the state of all applications can be reconstructed
the specific application scenario of EOS cryptography currency can be explained as:
receiver payment: customers purchase specific procts from the business, and the sales revenue of these procts will be used to pay the business cost, so as to avoid customers paying for the use of blockchain directly, and will not restrict or prevent enterprises from determining the monetization strategy of their procts
authorization capability: if a blockchain is developed by using EOS software system and its token is held by a ticket holder, it may not need to consume all or part of the available bandwidth immediately. Such a holder can choose to give or rent the unused bandwidth to others
separate transaction costs from token value: if the application owner holds a corresponding amount of tokens, the application can continue to run in a fixed state and bandwidth usage. Developers and users are not affected by price fluctuations in the token market, so they are not price dependent
block reward: each time a block is generated, the eos.io system will reward the block generator with a new token. The system may be configured to limit the reward cap for block procers, so that the total annual increase in token supply does not exceed 5%
community welfare applications: users can choose three community welfare applications, also known as smart contracts. These smart contracts will collect tokens based on the proportion of votes each application receives from the token holder. The elected application or smart contract can be replaced by the smart contract of the newly elected application or token holder
What are the technical advantages of EOS
1. EOS creates a developer friendly underlying platform of blockchain, which is similar to the operating system of blockchain. It has powerful performance, can support multiple applications running at the same time, and can support multiple programming languages at the same time. It provides developers with underlying moles to lower the development threshold, just like Microsoft's windows. Do you think Microsoft is worth money
2. EOS solves the problems of delay and data throughput through parallel chain and dpos. EOS can achieve a processing capacity of one million per second. At present, bitcoin has 7 transactions per second, while Ethereum has 30-40 transactions. This super power of EOS can hang bitcoin and Ethereum. For example, the recent cryptokitties | collect and breed digital cats! This is a very popular eth game. Only one game accounts for about 15% of eth's throughput. If there are seven or eight similar games at the same time, ETH will die. It's scary to think about it. Eth, which can't expand bandwidth, will have great challenges in throughput, and EOS can solve the above problems.
In fact, Ethernet is an electronic virtual currency, which is regarded as "bitcoin version 2.0". The blockchain technology "Ethereum", which is different from bitcoin, is the real reason to win Putin's favor
Ethereum is an open-source public blockchain platform with smart contract function. It mainly provides decentralized virtual machine to process point-to-point contracts through its special encrypted currency Ethereum, which is fast and unlimited in quantity. In other words, it is a monetary payment system, but their functions and purposes are different
if bitcoin is considered to be a shared global book that securely records all bitcoin bills. Then Ethereum is to maintain a shared computing platform, which can flexibly and safely run any program users want. Because of this, many countries and enterprises are developing how to use Ethereum technology in the real world
the latest price of eth on btctrade platform of bitcoin trading network is ¥ 2430! The increase is amazing
blockchain Ethereum is widely used
at present, the application of Ethereum technology in Russia is still relatively positive. For example, veb, the state-owned Development Bank of Russia, began to apply Ethereum technology to some administrative functions last week, and Russian steel giants are also testing the application of Ethereum in the safe transfer of international letters of credit. Therefore, Putin believes that this virtual currency can help Russia diversify its economy and support the paving of the way by blockchain technology and the establishment of new businesses
not only Russia, JPMorgan Chase, Microsoft, Intel and others are optimistic about Ethereum technology. At the same time, Ethereum has also been paid close attention by some financial institutions, banking consortia, Samsung, IBM and other large companies, resulting in the simplification and automation of financial transactions, merchant loyalty index tracking, customer satisfaction index tracking, customer satisfaction index tracking, etc Blockchain applications such as gift cards are designed to achieve decentralization of electronic transactions. That's why the etheric currency is rising
the future of ether coin
of course, different from Ethernet, there are 670 bitcoin ATMs in the world, and thousands of outlets support bitcoin payment, but Ethernet has not yet emerged in the field of electronic payment. Mainly used to support the Ethereum network to run the program. Therefore, whether bitcoin will be recognized in the future is still unknown, but what Russian President Vladimir Putin has done may not be a signal
we have said before: it is still difficult to define bitcoin as currency, but it must be an asset, and I think Ethereum must be an asset. Although the application of blockchain technology is not yet mature, in a sense, it will be used sooner or later. After all, in the future era of big data, blockchain technology can better protect the efficiency and privacy of our information
this is why digital currency Ethereum is so popular
hope to adopt
Bitcoin is not the only digital currency on the Internet. There are also ripple, stellar, litecoin, Ethereum and other digital currencies. Of course, the most popular is still bitcoin. But many times, some developers, entrepreneurs or enterprises will let us know that we need better digital currency. A programmer named Jed McCaleb, the father of electric donkeys, developed the reborn coin, which should be better than the bitcoin. Later, he launched the star coin, which is better than the reborn coin. What is more gratifying is that he is not fighting alone
now there is a trend that the instry hopes to develop a technology that enables all these online digital currencies to flow to each other, which means that you can transfer money freely in different online digital currency systems in the future. This technology is known as "interleaver protocol (ILP)", initiated by ripote. However, in recent months, that is, after the company released this idea, they also got the support of many famous companies in the instry, including Microsoft and the world wide web. Obviously, Ruibo currency company wants to set the technical standard of digital currency on the Internet. They want to develop a single global network, which can not only unify all digital currencies, but also unify all enterprises and indivials who use these digital currencies
"we want to be on a higher level and extract the differences between various digital currencies," said Stephen Thomas, chief technology officer of ripple. "We are trying to develop a global standard for payment."
with the launch of this agreement, we hope to enable more people to use online digital currency, expand the scope of use of online digital currency, and let us transfer funds more efficiently. This is actually the goal of many existing projects. For example, the original intention of the design of reborn currency and star currency is to allow users to transfer money to these two digital currency accounts in any currency, and to enable these two digital currencies to be converted into other currencies correspondingly. You can send bitcoin, and then the other party gets it. You can also send us dollars, and the other party will get dogecoin. However, for businesses and the developer community, there are restrictions on their use of these ledgers, so there are some problems because you can't transfer money from one payment network to another. Now, however, the interleaver agreement hopes to change that
to some extent, after ten years of efforts, they hope to develop a new network protocol, which is commonly known as "money Internet". If we go back to the early 1990s, we know that the famous Marc Andreessen founded the Netscape web browser. Now, the project hopes to play a similar role. They want to establish a standard way to send funds on the Internet. In fact, the original Hypertext Transfer Protocol (HTTP, which defined the basic standard of the network) contained code for payment. But this code has never been used. In recent years, many companies (such as coinbase, a bitcoin exchange, and stripe, a company that helps enterprises accept various online digital currencies) are at least trying to create a conventional standard for online digital currencies. In the future, we hope to be able to send and receive money online, just like sending short messages or e-mails. However, we still have a long way to go to this paradise, but at least now we are in the right direction
Many places in China are experimenting with the use of digital RMB, and the convenience of digital RMB is as follows:
First: Digital RMB can be used offlinealthough mobile payment is very common now, any third-party payment software needs to be connected to the Internet. Alipay and WeChat also monopolize the third party payment market, but once these two software are not connected, they will not be able to complete the payment. Although it's all right to go out with your mobile phone now, you don't need to bring your wallet and cash, but all this is based on the fact that your mobile phone has electricity and network
The consumption habit of
is unhealthy, so digital RMB is actually a more real and planned payment method, which is helpful for young people to develop good consumption habits. This can avoid over consumption and other bad habits
