What is the best blockchain technology

1. 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
blockchain is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry
in April 2018, a group of scholars from Oxford University announced the establishment of Woolf University, the world's first blockchain University
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.

2. For the first time in history, block chain has established a consensus on decentralization from the technical level, which has brought unprecedented technological innovation and first brought impact to the financial field. At present, it has been graally applied to securities, banking, insurance, credit, auditing, electronic bills, etc. on the one hand, famous financial institutions such as NASDAQ, NYSE and London exchange in Europe and America have invested huge resources in development, on the other hand, more than 50 banks such as Goldman Sachs, UBS and Citibank have started blockchain research and related financial innovative applications. At the same time, some international famous companies, such as IBM and Microsoft, have graally opened their blockchain development platform interfaces. The development of blockchain has been greatly accelerated, which can be said to be changing with each passing day<

the significant characteristics of blockchain decentralization are as follows:
1. Decentralized owner
2. Decentralized data storage
3. Peer to peer verification of related party transactions

at present, only a few domestic enterprises have broken through blockchain technology, mainly Shenzhen Qianhai Morgan Digital Technology Co., Ltd.

3. The following points are the characteristics of the blockchain summarized by jinwowo group:

1 - Decentralization: because the blockchain relies on each node to achieve system maintenance and ensure the authenticity of information transmission, it is based on distributed data storage without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network

2-DE Trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud

3 - extensible: blockchain is an underlying open source technology, on which various kinds of extension, decentralized and distrusted applications can be realized<

4 - anonymization: the two sides of data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information

5 - Security and reliability: because the activities between any nodes are supervised by the whole network, and the database adopts distributed storage, for hackers, first, they can't disguise and cheat, Second, we can't control the network only by conquering a node.

Recently, many friends have come to ask questions about blockchain, such as the specific advantages of blockchain, why to invest in blockchain, and what benefits can it bring? Can't you invest in real estate and wait for the appreciation; Can't you invest in a mature market like stocks and bonds? Why invest in the emerging blockchain? Does blockchain have any investment value? And so on a series of questions, I have made the following summary, basically summarized the answers to most of the related questions:

< p class = "ikqb_ image_ Blockchain is regarded as an important part of the fourth instrial revolution. We all know that every instrial revolution will bring leaping progress of human proctivity. The history of human development is actually a history of proctivity progress.

it can be summarized in the following four aspects:

1. Blockchain has a good market prospect; 2; As an emerging technology, blockchain is recognized by many professionals including investors. It is estimated that the market value of blockchain will be about US $60 billion in 2020 and US $20 million in the global market in 2024. The considerable market prospect of blockchain is obvious

2. The cost of block chain is less; Compared with the centralized mode of relying on third-party intermediaries such as credit card payment and stock trading, the decentralized distributed structure of blockchain saves investors high handling fees and transaction costs, saves investment costs and improves transaction processing efficiency

3. Block chain is more secure and stable; The traditional centralized mode often faces serious credit crisis, but because each transaction in the blockchain is tracked and permanently recorded by the distributed public account book, the phenomenon of forgery is greatly reced, and the losses caused by the credit problems of the third party are avoided, providing security for investors' transactions

4. The programming attribute of block chain is more standard; Traditional market investors often affect their earnings because of the confusion of market levels, and the programmability of blockchain makes the market level clear, which is an innovative technology that can change people's lives

I hope it can help you to solve related problems. Please feel free to ask or discuss more details or any questions

5. 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< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, 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< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled 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 information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy
