Global blockchain distributed

1. bitcoin and blockchain international summit aims to popularize the knowledge of bitcoin to more people while promoting the technical exchanges between domestic and foreign cryptocurrency instry and blockchain. The "China's first bitcoin documentary" brought by the summit is the best proof. I hope more people can learn about bitcoin and blockchain through this documentary, and explore the future together.

Blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

3. Blockchain is a kind of distributed ledger technology. By safely storing information across multiple systems, and by creating reliable "truth" sources, it realizes the intermediary of so-called "trust intermediary", so as to realize point-to-point transactions. Relying on secure distributed storage for verification brings a paradigm shift of trust building, which has a profound impact
in the future, jinwowo network technology will continue to tap the value of blockchain technology in the commercial field, give full play to the advantages of big data services, add value to user behavior, break the ice for the development of small and medium-sized enterprises, and build a real, efficient, safe and honest Internet community of destiny.

4. "A network-based computer processing technology, corresponding to centralized. As the performance of personal computer has been greatly improved and the popularity of its use, it is possible to distribute the processing power to all computers on the network. Distributed computing is a concept opposite to centralized computing. The data of distributed computing can be distributed in a large area

5. The development of blockchain? Now is an era of technology driven financial development. The driving factors of technology have developed from the earliest Internet information to big data, cloud computing and mobile Internet in recent years. However, technological innovation is endless, and blockchain, as a driving force of science and technology, has shown a vigorous development trend

as a blockchain with decentralized concept and distributed shared accounting technology as the core, it will be embedded in many links in the financial field in the future, such as credit enhancement, right confirmation, equity registration, financial trade, digital assets, etc. Blockchain is still in the primary stage of development, whether it is a large institution or a small company, blockchain is still on the road of exploration. As a distributed shared accounting technology, the latest and most cutting-edge technology in the field of financial technology, blockchain, in a greater sense, enables the parties involved to establish a trust relationship at the technical level. At present, this technology has a lot of imagination in the field of equity registration, right confirmation, clearing and settlement in the financial field, as well as in the field of logistics and proct authenticity traceability. Bubi's blockchain points out that at present, more Bubi's technologies are focused on commercial level blockchain technical support services, which specifically includes three areas. First, the field of digital assets includes other digital assets in addition to common points and check-in cards; The second is trade finance; The third is the field of equity, to improve the convenience of equity trading

the development history of blockchain? Blockchain will bring a new revolution in asset ownership in the future“ The first generation of Internet information solved the free transmission of information, but did not solve the problems of decentralization and asset ownership. " This problem can not be underestimated. At the level of capital market, if any technology can clarify the property rights of things that are uncertain, it will be a huge change for the whole market. In addition, blockchain will also lead the great changes in the field of credit enhancement. It is reported that China has about 700 million Internet users“ If every netizen adds tens of thousands of credit lines through blockchain technology, the amount of credit increase will be trillions nationwide, and it can be proved that all your credit is universal in the world at the level of blockchain. " In the future, three things will happen in Internet finance. First, there will be a good matching mode between asset side and liability side; Second, intelligent investment with two main modes of follow-up investment, suggestion and notification; Third, blockchain
"the blockchain model, as a foundation, rather than a business model, will solve a lot of credit problems. The largest blockchain market in the next three to five years should be in China."

Introction to Bubi blockchain

since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely

has blockchain solved any problems

the most important thing of blockchain is to solve the problem of intermediary credit. In the past, it was difficult for two people who didn't know and trust each other to reach cooperation, and they had to rely on a third party. For example, in the past, there must be a bank or an institution such as Alipay. However, through the blockchain technology, bitcoin is the first time for human beings to complete the transfer behavior that can be trusted by both parties without the participation of any intermediary. This is a major breakthrough in blockchain

the development of blockchain? The history of blockchain development

blockchain technology is the underlying technology of bitcoin. In the early days, not many people paid attention to the underlying technology of bitcoin. However, bitcoin has been running stably for many years without any centralized organization operation and management, and there have been no problems. So many people have noticed that the underlying technology may have a great mechanism, and it can be used not only in bitcoin, but also in many fields. Therefore, bitcoin technology is abstracted, which is called blockchain technology or distributed ledger technology. So from a certain point of view, bitcoin can be regarded as the first application of blockchain, and blockchain is more similar to the underlying technology such as TCP / IP, which will be extended to more and more instries in the future.

6. In short, it is an important concept of bitcoin

7. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS abroad and Binhe Yun patent technology and application landing in China are much higher than those of large companies.

Overnight, blockchain has become the hottest topic in A-share market. The frequent trading of concept stocks related to blockchain has caused many listed companies to clarify their relevant business, while some companies disclose the progress of relevant business on the interactive platform, intentionally or unintentionally "rubbing" the concept of blockchain

in the peripheral market, the concept of blockchain is also pursued by capital. Kodak launched its own Kodak coin, an encryption currency provided to photographers. As soon as the news was announced, Kodak's stock soared to $5.02 per share, up 60%. UBI blockchain Internet, another blockchain company, a consulting company headquartered in Hong Kong, China, saw its stock price soar by more than 1000% last year. On January 8, this year, the securities and Exchange Commission of the United States announced the freezing of trading, which lasted from January 8 to January 22

9. Blockchain itself is composed of distributed nodes. Yinying China has started to study and test the blockchain project, and the digital currency crowdfunding platform launched is also very avant-garde
the so-called distributed computing is a computer science, which studies how to divide a problem that requires a huge amount of computing power into many small parts, and then assign these parts to many computers for processing, and finally synthesize these calculation results to get the final results. Distributed network storage technology is to store data in a number of independent machines. The distributed network storage system adopts the scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate the storage information. It not only solves the bottleneck problem of single storage server in the traditional centralized storage system, but also improves the reliability, availability and scalability of the system.
