Blockchain solution for chemical industry
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
the so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data< Advantages:
1) the algorithm is simple and easy to implement
2) there is no need to exchange additional information between nodes to reach a consensus
3) it takes a lot of cost to destroy the system< Disadvantages:
1) waste of energy
2) it is difficult to shorten the block confirmation time
3) the new blockchain must find a different hash algorithm, otherwise it will face bitcoin attack
4) it is easy to generate bifurcation and needs to wait for multiple confirmations
5) there is no finality, and checkpoint mechanism is needed to make up for it.
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 future2. Blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
3. Blockchain will be widely implemented in the real economy in the next three years and become an important support for the construction of Digital China
4. Blockchain creates a new platform economy and opens a new era of sharing economy
5. Blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy
The blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidatedRenren chain is an enterprise level platform service based on mainstream blockchain technology, which can help you quickly build a more secure and stable blockchain environment, rece challenges in blockchain deployment, operation and maintenance, and development, and enable you to focus more on core business innovation, so as to realize fast business on the chain
in the current enterprise management mode, no matter customer relationship management, project management, procurement management, human resource management, there are data security and reliability problems to some extent. For example, sometimes transaction data under the market mechanism is untrue / fake / deleted and changed, and some problems such as making ill considered decisions e to data resource blocking occur, In the long run, it will cause harmful business impact on enterprises. Moreover, some enterprise systems are lack of real-time tracking in the process of the project, which is prone to data disorder and lag, resulting in the inability to timely monitor the project and track the responsibility, low management efficiency and so on, which can be avoided in the early selection of enterprises!
health, ecation, agriculture, civil affairs, government affairs, energy and other instries can apply blockchain technology.
