Blockchain talent show
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
1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain
Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain
four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data
5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network
these five blockchain companies are probably well-known in China, and I personally recommend bumeng
first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy
Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it
Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear
Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain
finally, for all my hard work, choose me!

He is an EOS open source contributor and has developed many blockchain cryptocurrencies. He once served as Google algorithm engineer and a gold medal lecturer in Microsoft tech.ed conference. He is the most valuable expert in the field of artificial intelligence and blockchain in the world. He also has 15 years of programming experience and 5 years of teaching experience. He is a senior software architect and Intel Software Technology expert. The teaching and research team of blockchain college led by him is mainly composed of master's and doctoral students who graated from Tsinghua University, Peking University and other well-known institutions
the team has rich practical experience in blockchain and has won many blockchain competitions.
each block is filled with transaction records, and the blocks are connected in sequence to form a chain structure, which is the blockchain ledger
blockchain technology divides the data to be stored in the database into different blocks. Taking bitcoin as an example, when miners generate new blocks, they need to calculate the new hash value and random number according to the hash value of the previous block, the new transaction block and the random number. Each block is linked to the back of the previous block through specific information, and connected in chronological order to present a complete set of data. In other words, each block is generated on the basis of the previous block data, which ensures the uniqueness of the blockchain data
each blockchain database is essentially an event chain connected in chronological order, which uses the cryptographic mechanism specified in the protocol for authentication to ensure that it will not be tampered with or forged. With the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid
there is no distinction between mobile and non mobile end in blockchain, and if there is one, it is also a gimmick.
it should be noted that this is the recharge price. If it's selling q-coin, because q-coin recycling is now done by some third-party platforms, there will be a certain cost. Therefore, the recovery price of Q coin is generally lower than the recharge price, remember!
