Ethereum token project source code
just like bitcoin, Ethereum is neither controlled nor owned by anyone - it is an open source project created by many people around the world. Different from bitcoin protocol, Ethereum's design is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform. With the release of homestead, anyone can use the applications on this platform safely
Ethereum is a programmable blockchain. It does not give users a series of preset operations, but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator.

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.
generally speaking, Ethereum is an open source platform, digital currency and blockchain platform, which provides developers with a platform to build on the blockchain
A few days ago, Renren TV's official website published a news about "retired hard disk processing" and its high price, which has aroused the attention of many movie fans and drama fans. Beijing Business Daily reporter learned that the hard disk of Renren film and television processing brought us TV series, Japanese TV series, Korean TV series, movies, documentaries, open classes and other related resources, and sold them to users according to the size of the hard disk capacity. It is not the first time that Renren film and television, which has been in the whirlpool of right disputes for many years, has made the decision to "deal with hard disks". Behind these hard disks, which carry a large number of film and television resources and cost tens of thousands of yuan, an image of money shortage and crazy exploration on the edge of infringement has graally become clear
according to the capacity of hard disk and the content resources stored, Renren TV has set four packages for users to choose. Package 1 is a "super finished proct package", priced at 10000 yuan, with a total of 30tb, including all subtitled American TV series, Japanese TV series, Korean TV series, movies, documentaries and open classes released by Renren film and television. The final update date is June 23, 2019; Package 2 is the "super Hd 1080p movie source package". There are 5000 popular movies in the 50tb capacity, all of which are subtitle free Blu ray HD Movie sources, and the price is 17000 yuan; Package 3 is set as "super American TV series without subtitles", with a total capacity of 90tb, storing nearly 100000 episodes of American TV series, and many popular American TV series. Of course, the price of the package is relatively high, with a price of 25000 yuan; In addition, package 4 is only 10TB, and the contents include "selected American dramas + Movie updates + 1080p subtitle Free HD source of the hottest American dramas", priced at 3000 yuan
in order to further understand the situation of retired hard disk, Beijing business daily tried to contact Renren film and television through the official platform and leave a message, but there was no response at the time of publishing. However, it can be seen from the introction that Renren film and television is still cautious about selling hard disks, and marked with the following information: "all payments will be made on wechat, and delivery will be arranged after payment without refund", "wechat and all contact information will be deleted 15 days after the completion of the transaction", etc
suspected of right infringement as early as 2011, Renren film and television once claimed that the subtitle group launched the activity of "group buying hard disk" on the fifth anniversary of its establishment, and set the price at 699 yuan, 1399 yuan and 1980 yuan respectively, with content resources such as American dramas, documentaries and movies
coincidentally, in that year, Shanghai quanju Network Technology Co., Ltd., which belongs to Renren film and television, was established. According to the data of Tianyan, the company was registered on November 24 of that year, and its legal representative was Jiang Zhengpeng. In the brand introction, Renren film and television was introced as a non-profit organization. In addition, in 2017, Renren film and television also announced the sale of hard disk on the official microblog, and launched seven sales schemes according to the size of hard disk capacity and content resources
Zhao Hu, partner of Beijing Zhongwen law firm, believes that if Renren film and television fails to get authorization, it will be suspected of infringement if it adopts this method to sell its content resources“ Copyright covers the right of reproction, and the operation mode of Renren film and television is a typical act of reproction. And according to the relevant requirements and standards of the crime of right infringement, the amount of illegal business more than 50000 yuan can constitute a crime. Therefore, the behavior of Renren film and television will not only be suspected of infringement, but also serious illegal and criminal behavior. "
Renren's operation has also attracted relevant discussions. According to practitioners, it should be related to the operation status of subtitle group. Beijing Business Daily reporter learned that the operation of subtitle group is also a cost-effective process. A member of a domestic subtitle group told Beijing business daily, "it seems that the subtitle group is just carrying resources, but it also has a lot of operating costs. First of all, not to mention the cost of manpower, just to meet the download needs of users, the subtitle group needs to rent a server. The more users there are, the higher the cost of the server will be. The annual cost of some larger subtitle groups on the server can reach more than 100000 yuan. In addition, in order to obtain resources, subtitle groups also need costs. Some will buy genuine resources from overseas and then go to the domestic translation line, which also needs funds. In order to be able to operate with funds, subtitle groups also began to cash in different ways, such as publishing advertisements with traffic, selling hard disks, etc
struggling for transformation
since its first launch in 2004, Renren film has gone through 15 years. However, in the past 15 years, the right issue has been an unavoidable constraint for Renren film and television. Public information shows that on November 22, 2014, Renren film and television once posted a post announcing that "the station is temporarily closed today, and issued an announcement that it is cleaning up the content. Thank you for your love and support.". On December 20, 2014, Renren film and television subtitle station declared officially closed. Just when people thought that the era of subtitle group would end, Renren film and television posted on its official website in early January 2015, "silkworm is about to change, please look forward to it!", At the same time, version 1.0 of Renren American TV series was launched
but just one year later, Renren announced that the members of Renren did not really participate in the Renren American TV app project, and the "independent subsidy" promised by the latter to Renren has not been fulfilled, so the cooperation between the two sides ended. Subsequently, "independent" Renren film released an announcement to announce its return
however, after the return of Renren film and television, not only the right problem has not been solved effectively, but the capital chain has been under pressure repeatedly. In August 2017, Renren film and television released its microblog and revealed that it had financial problems, saying that because the R & D client squandered its reserve funds, it hoped that netizens would download and register a game to help them get promotion fees; In March 2018, Renren film and television announced its attempt to accept digital currency donations through the official microblog, so as to rece the bandwidth pressure and development expenditure pressure of the client, and attached the addresses of the donated bitcoin, Ethereum and bitcoin wallet on the official website
"looking back at the years from 2009 to 2016, it is the stage when the major domestic video website giants inlge in using money to smash the right of overseas dramas. A large number of high-quality rights were introced through legitimate channels. After years of free cake, they were taken away by others, which hit the subtitle groups including Renren film and television. It is precisely in recent years that the consumption habits and right awareness of the public have also changed significantly, which is undoubtedly worse for subtitle groups. " Liu Chang, a film critic, said
Zhao Hu stressed that people will inevitably have the mentality of taking advantage and want to get "free lunch". Although this kind of demand belongs to the moral level, and the law cannot directly intervene, the law can govern from the perspective of operation, so as to prevent those platforms that supply pirated resources from operating, and there will be no harm if they can't buy or sell. Compared with the past, domestic piracy has been much less, many pirated sites have been destroyed, and people engaged in piracy, including BT paradise webmaster, have also been sentenced, which proves that strict law enforcement can effectively rece piracy. However, if we want to completely eliminate the piracy problem, it is very unlikely at present. We can only find out that we can fight together, and graally rece the piracy through continuous fighting
