World famous blockchain Technology Organization

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

At the tokensky blockchain Conference on March 14-15, Zheng Xiaojun, director general of wbo, mentioned that the wbo licensing authority will issue three types of licenses: digital asset operation license (for ordinary digital asset companies), digital asset trading license (for digital currency exchanges, etc.) and ICO license (for ICO only projects, companies, etc.)

it is understood that the world blockchain organization is a non-governmental organization registered by the United Nations Economic and social affairs agency. Its purpose is to become a major international intergovernmental organization in the blockchain instry and provide another method and means to solve the financial problems between countries and regions by promoting the cooperation of the blockchain world

at present, wbo has more than 400 members and institutions, including nine offices including the licensing authority, to operate blockchain policy research, legislative promotion, standard formulation, evaluation and certification, conferences and exhibitions, training and ecation and other activities

the wbo with endorsement from international organizations will issue licenses related to digital cryptocurrency and blockchain, which may provide clearer guidance on supervision and practice at the national level, and bridge the cooperation between countries

as a financial technology leader, the United States discussed cryptocurrency, ICO and whether the existing regulatory framework is sufficient to protect investors at the recent congressional cryptocurrency regulatory hearing. Many of them agreed that the regulatory authorities should clarify the legal status of encrypted assets, and ensure that the relevant processes comply with the law while helping entrepreneurs to innovate

it is worth noting that on March 11, the blockchain instry alliance of China Hi Tech Instrialization Research Association also announced that it has officially joined the ranks of wbo sponsors, and Zhu Tao, chairman of the alliance, is also the deputy director general of the world blockchain organization. With the issuance of internationally recognized licenses, will China's policies be relaxed

On July 19, the 2018 global media blockchain summit was held in the financial hall of the Hong Kong stock exchange. A number of participating media, centering on the development prospects of blockchain and the trend of the instry, made suggestions on deepening the cooperation of media blockchain and promoting the healthy development of the instry, and jointly announced the establishment of the global media blockchain alliance

Ding Laibin, Secretary General of global media blockchain alliance, said that blockchain technology is expected to bring new social changes and needs to care for its healthy development. In terms of public opinion supervision in the field of blockchain, the media should give full play to its role, tap instry value, crack down on instry fraud, and make good contributions to the development of blockchain instry

Original title: China's blockchain instry market status and development trend analysis in 2019, widely used to accelerate the construction of Digital China. Basically, a relatively mature instrial chain has been formed. With the promotion of national policies and the increasing demand of downstream application fields, the market scale of China's blockchain instry is constantly developing, the regional concentration is high, and the instrial cluster effect is obvious. With the increasing maturity of blockchain technology, the blockchain instry is entering the 3.0 stage as a whole. It has a good performance in finance, logistics, right protection and other fields, and has made great contributions to promoting China's digital construction and accelerating the process of Digital China

instrial chain analysis of blockchain instry: there are many downstream application fields with huge development potential

from the perspective of instrial chain, China's blockchain instry includes upstream hardware, technology and infrastructure; Midstream blockchain application and technical services

application fields of downstream blockchain. The upstream hardware, technology and infrastructure mainly provide the necessary hardware, technology and infrastructure support for blockchain application. The hardware equipment includes mining machinery, ore pool, chip manufacturer, etc; General technologies include distributed storage, decentralized transaction, data service, distributed computing and other related technologies

the downstream application fields include the combination of application blockchain technology and existing instries, mainly including financial instry, logistics instry, right protection, medical health, instrial energy and many other fields. As an emerging technology, blockchain has many downstream application fields and great development potential

the application and service of midstream blockchain includes the construction of infrastructure platform and the provision of technical service support. The construction of infrastructure platform is divided into general infrastructure chain and vertical domain infrastructure chain; Technical service support includes technical support and service support. Similar to upstream technology, technical support is responsible for providing buyers with a series of technical support based on blockchain procts, such as blockchain security protection; Service support includes a series of services such as digital asset trading place, digital asset storage, media community, etc

instry chain analysis of blockchain instry Most of 360 and other enterprises use their own financial companies to apply blockchain technology to launch a new mode of blockchain + finance and broaden the application scenarios of blockchain technology

With the continuous development of China's blockchain technology and the continuous expansion of blockchain application fields, China's blockchain instry will become the forefront of global technology development and open up a new international competition track in the future

2. Blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
