Early Ethereum
although the pow mining mechanism is adopted, the block out mechanism of Ethereum is different from that of bitcoin. Due to the short block time of Ethereum, Ethereum is easy to form isolated blocks. Isolated blocks refer to the blocks that are not on the longest chain. Bitcoin's isolated blocks have no block rewards, but in Ethereum, isolated blocks can be referenced. The referenced isolated blocks are called "Uncle blocks", and their packaged data will also be recorded in the blockchain. Unlike bitcoin, Ethereum's TERT block has a reward, and each TERT block can get a reward of 4.375 Ethernet coins at most
Ethereum is a programmable and Turing complete blockchain development platform, which is equivalent to a decentralized global computer. In a programming system, there are usually some virtual machines to compile and execute. Java has JVM. In Ethereum, there is also Ethereum's virtual machine EVM, which can execute any complex algorithm code. Developers can use existing programming languages such as JavaScript or Python to create their own applications on Ethereum. Through Ethereum's virtual machine, you can easily issue digital assets, write smart contracts, set up and run decentralized applications, and set up decentralized autonomous organizations
eth is also known as the internal fuel of Ethereum. Unlike currency digital assets, Ethereum is not only used for transfer, but also for payment of smart contracts
in order to prevent the Ethereum blockchain from being full of junk contracts and junk applications, and to establish and run smart contracts on Ethereum, you must use eth to pay for smart contracts. For example, when you transfer your newly created digital assets on the Ethereum blockchain, you need to use eth to pay the handling fee instead of your newly created digital assets.
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
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 projectsICO (abbreviated as initial coin offering) is the concept of initial public offering (IPO) derived from the stock market. It is the behavior of blockchain project to issue token for the first time and raise bitcoin, Ethereum and other general digital currencies
brief introction to ICO:
ICO is a blockchain instry term, which is a common way to raise funds for cryptocurrency / blockchain projects. Early participants can get the cryptocurrency generated initially as a return
because the token has market value, it can be converted into legal currency to support the development cost of the project. The tokens issued by ICO can be based on different blockchains. The common issue is based on Eth and BTS blockchain, which provides bookkeeping service and value consensus to realize global issue and circulation
ICO participants are very important for the success of a project. They will publicize the blockchain project in the community, so that the tokens generated by it can obtain liquidity before the transaction starts. However, the most important value of ICO participants is still the potential benefits brought by the project development or the price appreciation after the token issue
extended information:
domestic prohibition:
at 3:00 p.m. on September 4, 2017, the people's Bank of China led seven ministries and commissions, including the Information Office of the people's Bank of China, the Ministry of instry and information technology, the State Administration for Instry and commerce, the China Banking Regulatory Commission, the China Securities Regulatory Commission and the China Insurance Regulatory Commission, to issue the announcement on preventing the financing risk of token issuance (hereinafter referred to as the announcement)
the announcement points out that token issuance financing is essentially an unauthorized illegal public financing behavior, which requires that all kinds of token issuance financing activities should be stopped immediately from the date of the announcement, and at the same time, organizations and indivials who have completed token issuance financing should make arrangements such as refund
The full name of HT is Huobi token, which is a global common scoring system based on blockchain issuance and management. The analysis is as follows:
(1) the total amount of HT issuance is limited to 500 million, 100% of which is used for gift
(2) 60% (300 million) of them were used to purchase point card packages and 20% (100 million) were used for user rewards and platform operation; 20% (100 million) for team motivation, with a lock-in period of four years and 25 million per year
(3) purpose of fire coin: when HT is used to buy VIP, different levels of VIP enjoy different discount of service charge, and the maximum discount of service charge is 50%. At the same time, HT can be used as a deposit to become a legal currency transaction certification business, which can obtain exclusive certification marks and one-to-one customer service. HT can also be used in hadax voting, hadax project party margin, super node, super partner and fire coin global ecological fund scenarios

(1) fire coin is a safe and reliable bitcoin trading platform in China. It has obtained a round of 10 million RMB capital investment from Zhenge fund, Dai Zhikang, Sequoia Capital (shareholders of many global well-known companies such as apple and Alibaba). Fire coin implements strict risk control management and operates stably. As of the end of 2016, the accumulated turnover of fire currency reached 200 billion yuan
(2) in the future, Huo coin will mainly focus on overseas transactions. Founder Li Lin said in an open letter that he is currently carrying out five major businesses around the world, including fire coin global professional station, fire coin Korea, fire coin China, fire Coin Wallet and fire coin global dollar station
(3) among them, fire coin China focuses on blockchain technology R & D and application information, while fire coin Korea and fire coin global dollar station will continue to provide local legal currency to digital currency digital asset trading services
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
Ether coin
related introction:
eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0", and uses the blockchain technology "Ethereum" different from bitcoin
The system ofEthernet coin is the most widely used public blockchain system supporting complete application development. Compared with bitcoin, Ethereum belongs to the category of blockchain 2.0, which is a new blockchain system designed to solve some problems of bitcoin network
extended data
related background:
the emergence of Ethereum is to help users more easily use blockchain technology for application design. According to BARTLIN, the purpose of Ethereum is to create a more general blockchain platform, which can allow users to easily create blockchain based applications and avoid users having to build a blockchain in order to create a new application
generally speaking, the previous blockchain was only a single tool or at most a combination of multi-functional tools, while Ethereum is the smartphone of blockchain, and users can use the smartphone to build any "application" they need. Therefore, BARTLIN said that the application of blockchain is not limited to cryptocurrency. It has great potential and can be applied to all walks of life. It can bring significant benefits to enterprises and organizations of all sizes
