Blockchain's most revolutionary
the most valuable part of blockchain is not technology, but the idea behind it.
no technology is omnipotent, so is blockchain technology. As a trust connector, the greatest value it brings to the times is the concept of openness, openness and transparency behind it, and the spirit of building a business with trust and honesty. Based on this spirit, the blockchain technology is like the most impartial machine judge, so that every information in its hands can exist permanently in the world and be tested by future generations.
add a signature
in each record. Each device in the block chain network maintains a complete and identical account
another feature of the block chain is that this ledger book is kept in every computer, and each one is exactly the same as the 2. This can ensure that one account book is damaged (the disk is damaged or tampered with to make it unusable), and the account books on other machines can still be used to ensure that the data will not be lost
the above two points are the core technologies for blockchain to establish trust relationship, which ensures that the data is reliable and can not be tampered with. This revolutionary realization of trust transfer between two strangers does not require the participation of intermediate institutions. With this foundation, the whole "new institutional economics" will no longer exist, and even the trust companies derived from it will be replaced, This is probably why Alipay announced the introction of block chain technology in January 2017. It is bold to predict that Internet Co will be built on the block chain in the future. What we can imagine is the property chain, food safety chain, financial service chain, chain chain and so on.
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. 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.
before blockchain, any transaction activity needs an intermediary. Without an intermediary, two strangers can not reach a transaction. Here comes the blockchain, replacing the intermediary with a robot, and using a set of mathematical algorithms to ensure that two strangers complete a transaction
blockchain is a machine of trust, which is its essence
"decentralization" is a result of blockchain. In economic transaction activities, the so-called "decentralisation" is nothing more than these meanings:
first, when we complete a transaction, we no longer need a third party, which is a center
secondly, all the economic activities on the blockchain no longer need the organization and system of "company" to help us complete various transactions
thirdly, when serving for a centralized organization, the centralized organization gives us jobs and wages to encourage us to better serve the cause, but the incentive mechanism on the blockchain is not established by the centralized organization.
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

e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
openness
the system is open, in addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all, and anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
autonomy
blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work
information cannot be tampered with
once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high<
anonymity
since the exchange between nodes follows a fixed algorithm, their data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective by themselves), so the counterparties do not need to trust themselves by disclosing their identities, which is very helpful for credit accumulation
At present, with the rapid development of science and technology, the situation is surging. If you and I are a little lazy, we may be out. No, the new blockchain is coming. Since the beginning of this year, blockchain has become one of the hottest knowledge points in the field of science and technology, and has become increasingly prominent in the fields of digital finance, Internet Governance and big data computing
blockchain technology also has broad application prospects in the military field, which is very likely to quietly subvert the future war
this is not Xiaole's boasting“ There is nothing more important about the three armed forces than secrecy. " We should know that in the future information battlefield, confidentiality is the key to win or lose the war. Because the blockchain system has many characteristics such as information independence, confidentiality and integrity, it can realize the perfect combination of data storage and data encryption. After being attacked, it also has strong recovery ability, and can protect highly sensitive data, which is of great help to win the war
according to the information collected by Xiaole, some countries are planning to build blockchain information platform and begin to study the application potential of blockchain in several scenarios such as military satellites and nuclear weapons; An international organization is currently evaluating the performance of blockchain technology in military logistics, Internet of things and other fields
if bitcoin and other digital currencies are blockchain 1.0 applications, blockchain 2.0 is the "smart contract" that provides a strong guarantee for network transaction data security. There will be 3.0 in the future, from Dao (blockchain self consistent organization), DAC (blockchain self consistent company) to blockchain society
"cultivate new kinetic energy with informatization, promote new development with new kinetic energy, and create new brilliance with new development." I believe that blockchain, the "new kinetic energy" of science and technology, will bring us more surprises: "one machine in hand, I have it in the world", "trade autonomy", more extensive sharing, and the optimal life mode... Blockchain technology will create a more honest, convenient, and efficient Era of big data
