Download of decentralized application blockchain Technology
In 2017, blockchain technology is undoubtedly a new wave of technology after the mobile Internet. From the three dimensions of technology implementation, commercial application and commercial realization, blockchain is expected to become a new technology after the mobile Internet, which will once again subvert people's digital lifestyle. At present, the new technology wave of blockchain fascinates more and more developers. Therefore, Neo, a non-profit community blockchain project, joins hands with Microsoft to open the first domestic blockchain developer competition, aiming to proce more excellent applications based on Neo blockchain and Microsoft's development environment and tools, so as to form a strong application ecology for blockchain developers
"People are using blockchain technology in a more interesting way as the basis for 'decentralized applications' rather than just applications like financial technology and cryptocurrency," said Mike Mason, technical director of the office of chief technology officer of ThoughtWorks, a global software consulting firm. You know, "blue ocean" has never lacked players. Some Internet companies are trying their best to land on the beach, and have established the blockchain instry market as an inevitable choice for development. In China, netxin technology, a wholly-owned subsidiary of Xunlei, has used blockchain technology in the innovative cloud computing mode - "shared computing"
earlier, Xunlei implanted the concept of sharing economy into the field of cloud computing, and created an original" sharing computing "mode. By collecting users' idle computing resources, Xunlei transformed them into innovative cloud computing services for enterprises, On the one hand, it can effectively solve the social contradiction between the shortage of social computing resources and the high cost of computing, on the other hand, it can greatly rece the operating costs of enterprises. In August 2017, Xunlei launched a new sharing economy intelligent hardware player cloud. Its significance lies in that in the shared computing ecosystem, Xunlei joined the blockchain technology to issue player coins to users who share idle resources such as bandwidth, storage and computing power through the player cloud intelligent hardware
playcoin is a digital asset created based on blockchain technology in the thunderbolt shared computing ecosystem. With the launch of playcoin, Xunlei has become the pioneer of blockchain technology in China, and also has many advantages in its shared computing. Firstly, playcoin, based on shared computing and blockchain technology, ensures that the payment and income of users' shared computing resources and content are equal through smart contracts, which cannot be denied; Secondly, through decentralized accounting records, all transactions are true and transparent; Third, register users' right and modify records through blockchain to protect users' right from infringement
in fact, blockchain technology has strong advantages in network security, cross-border payment and other fields, and also has important value for building a community of destiny in cyberspace. On October 31, 2017, Chen Lei, CEO of Xunlei group and CEO of netxin technology, put forward the all in blockchain strategy and announced that Xunlei will increase investment in blockchain technology starting from the player cloud to explore the application of cloud computing and blockchain technology integration. On the day of the press conference, playmaker cloud also signed a right content distribution agreement with 4K garden, trying to integrate shared computing and blockchain technology to provide a platform for right distribution and content distribution. In the future, blockchain will generate more application scenarios in thunderbolt's shared computing ecosystem. Xunlei's innovative attempt may give more inspiration to developers of other blockchain technology applications
at the same time, as a leading enterprise in the blockchain application market, Xunlei is also actively guiding the healthy development of blockchain applications, insisting on not doing ICO, not going to the third-party trading platform, and severely cracking down on the third-party platform for illegal trading of customer coin, and cracking down on speculation and speculation through such measures as the real name system of customer Coin Wallet. Therefore, blockchain application developers should also abide by the law and avoid risks
based on the blockchain technology, Xunlei's "player cloud" takes the lead in building the C-end application of China's blockchain technology, which promotes China's blockchain technology to participate in the ecological development of global blockchain and creates important value in the development of digital economy“ The development history of the Internet is a history of innovation and Entrepreneurship of Internet talents. " The development of blockchain also needs a lot of talent support. We are looking forward to the birth of "blockchain +" Application in the first domestic blockchain developer competition
The characteristics of decentralization in blockchain technology are decentralization, distrust and collective maintenance
Decentralization: there is no centralized hardware or management organization in the whole network, the rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system. Therefore, it can also be considered that the blockchain system has excellent robustness2. Distrust: there is no need to trust each other when participating in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are also open. Therefore, in the specified rule range and time range of the system, nodes cannot and cannot cheat other nodes
3. Collective maintenance: the data blocks in the system are jointly maintained by all the nodes with maintenance function in the whole system, and these nodes with maintenance function can be participated by anyone
extended data
blockchain technology has never excluded supervision, and supervision nodes can easily access any blockchain network. Because of the openness and transparency of the blockchain, the regulatory authorities can monitor the transaction data of the whole system more conveniently, and because of the anti tampering property of the blockchain
once a transaction occurs, it can't be changed or deleted, so it's impossible for the data fraud to hoodwink the supervision, which is more concive to the supervision of the regulatory authorities on the market behavior. Thus, blockchain will become an important tool for regulatory Technology (regtech)

If bitcoin represents blockchain version 1.0, it proves to the world that digital currency can be realized. Then Ethereum represents blockchain version 2.0, which lets you know more about the play of blockchain, decentralized applications and smart contracts. In 2018, blockchain will enter the stage of 3.0, application and scenario landing will be the core of blockchain, and blockchain based applications in various instries will spring up, which will be the early dividend period of the last stage of blockchain development. The demand for talents driven by the application of blockchain technology has become increasingly large. Blockchain technical talents have become the new professional talents, which are highly competitive, and also have enviable high salaries
whether to form a meaningful large-scale consensus: one of the outstanding advantages of blockchain is that it can effectively form a large-scale consensus by opening account books and notifying the whole network. At present, there is no need to form a network wide consensus for many projects. Some projects are just for crowdfunding and token issuance. The blockchain consensus of projects is meaningless. Does this model have network effect: network effect means that a project will become more and more valuable with more and more users of the project, because the value of the project is not in the users themselves, but in the connection network between users. Bitcoin is a typical example. The more user nodes there are, the more links between nodes will grow exponentially, and the whole ecosystem of bitcoin will be more valuable
of course, in addition to these points, there are many basic principles to judge the project, such as effective incentive mechanism, strong team, project solving pain points, and so on
With the rapid development of human society, many people find that decentralization is a trend and also represents a new proction relationship. This is a new kind of proction relationship that is suitable for the business or business logic based on the highly developed and market-oriented human society and economy, equality and mutual trust. Since the decentralized trust mechanism blockchain has been established, many intermediaries will also face upgrading and innovation. For example, "Wall Street", a traditional medium which is essentially a financial intermediary, may soon develop into a new model
decentralization has changed more than one financial instry. In the consensus of China's excellent Internet company "Xunlei", science and technology is developing from centralization to decentralization. They are proud that their first P2SP download technology is a kind of decentralized technology. At that time, blockchain was not widely recognized. Xunlei believes that decentralized technology has many advantages. Its solution is light weight and low cost; It respects privacy and doesn't have an intermediate database to know everything; It accords with the development of society; It is a measure of environmental protection and sharing. In 2014, Xunlei made up its mind to do decentralized cloud computing, also known as shared computing, which is to distribute the computing needs to thousands of households and use the idle resources of users
such an attempt has got a very good market response, because the marginal cost of shared computing is lower than that of cloud computing, which can more effectively solve the social contradiction between the shortage of social computing resources and the high cost of computing, and rece the operating costs of enterprises, including Xiaomi, Aiqi and Xiongmao live broadcasting, which have become the customers of thunderbolt shared computing. In fact, the demand for computing in the current society is growing explosively. Whether it is artificial intelligence, big data, 4K, VR, the demand for network is higher and higher, the speed of computing is higher and higher, and the demand for speed is higher and higher. If you want to solve all the needs, you need to prepare sufficient computing resources. The player reward scheme is born to solve this problem
the significance of the player reward program is that in the shared computing ecosystem, Xunlei has joined the blockchain technology to share the bandwidth with the players through the cloud intelligent hardware Users of idle resources such as storage and computing power will issue the digital asset chain gram (original gamer coin) based on blockchain technology. Users participate in this plan for free, and they also voluntarily contribute idle computing resources to the society. Users actively contribute idle resources, Xunlei payment chain rewards users, Xunlei then packages and sells resources to enterprises, and a supply chain based on shared computing is completed. In this process, decentralized blockchain technology plays an important role
of course, complete decentralization lacks supervision, and there is a certain risk of being used. Therefore, the blockchain chosen by chaink is "alliance chain", not a completely decentralized public chain like bitcoin and Ethereum. Therefore, Xunlei still has the right of supervision. In order to rece and avoid the occurrence of malicious events of accounting nodes, and to ensure that users' transactions enter the block as soon as possible, Xunlei is more cautious in selecting accounting nodes. In the initial stage, Xunlei will choose its own servers with good network connectivity and stability, as well as its partners' servers with good network connectivity and stability, After the performance and security of the next generation of gamer cloud hardware are further improved, the gamer cloud node distributed in the user's family will be selected as the accounting node and constantly changed. At the same time, Xunlei united government actively cracked down on speculation, announced the firm no ICO, cracked down on third-party transactions, adopted the real name system, unlimited pre-sale activities and other means to resolutely curb the risk of speculation, so as to ensure the stability and sustainability of the player cloud and chain ecology
with the emergence of blockchain applications such as chaink, we can see that decentralized technology can make the instry no longer become so extreme, and all kinds of opportunities will burst out because of the introction of new mechanisms, which is of positive significance to the instry and the whole society
every central node can generate blocks and write data, so every point is a central node, or the blockchain is decentralized. In order to control the whole system, more than half of the nodes must be controlled in order to control voting, so there is no administrator in this system.
Generally, it's legal, but I don't think it's reliable. If you put it in your wallet, it's equivalent to being there for others, so you can't make your own decisions
at present, the blockchain world all believe in a "God" named "Nakamoto Tsung". They all have a Bible named "bitcoin: a peer-to-peer e-cash system" written by Nakamoto Tsung, even though some blockchain projects in the future have started to be independent (such as eth, gucs, etc.), But it is still unable to change the essential characteristics of constant total circulation and "peer-to-peer payment"
However, the focus of attention is different. For example, Ethereum pays more attention to the development and deployment of smart contracts, while the recent big fire of gucs focuses more on the implementation of Inclusive Finance Gucs hopes that national and cultural differences will no longer be an insurmountable gap. Inclusive Finance will spread to every corner of the world, effectively rece the global gap between the rich and the poor, promote the upgrading of consumer finance, and improve the financial situation of small and micro enterprises and indivials around the world, so that the public can really control their rights and build a fairer and better societythe participants of the blockchain gather by following the same accounting transaction rule, which is based on cryptographic algorithm rather than credit. At the same time, every transaction in the network needs the approval of other users and records, so no endorsement from any organization is required, and the participants can't go back on their breach of contract.
