Real right blockchain
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
first of all, e to its lack of supervision, its circulation and trading forms are mostly similar to the issuance and listing of securities, and there is the behavior of setting up an exchange for trading. Its trading process and trading results are not transparent, and it is difficult to regulate when encountering problems. Moreover, its price formation mechanism is not transparent, and the trading price fluctuates greatly, which is easy to make investors suffer huge losses
secondly, it is not recognized by the central bank and can not be used as currency in China. Once it is subject to policy supervision, it is likely to encounter the risk that no one will take over the offer and the price will plummet, and the property law does not clearly protect the corresponding provisions of digital currency. Therefore, it is very dangerous to speculate on the blockchain, which is equivalent to streaking in the cold winter
finally, although blockchain is not illegal, it can not be ruled out that it is used by a small number of fraudsters and illegal fund raisers as a tool for crime and money laundering
therefore, it is recommended to carefully participate in blockchain investment to avoid irreparable losses.
blockchain originates from the underlying technology of bitcoin and is the blockchain technology of Internet. IP is connected by blockchain technology to form distributed accounting. It is not easy to tamper with and decentralize
code chain technology is the code chain technology of the Internet of things, which superimposes the Internet of things IDS one by one in a two-dimensional way to form personal records. The application of "code chain" technology will bring more efficient link forms of "people to people", "people to things" and "things to things"
Introction to code chain:
"code chain" refers to a "two-dimensional code chain" formed by using a smart phone to aim at the "two-dimensional code" and "scan", that is, to "generate a new two-dimensional code containing the scanner's DNA" and access to the "service". The whole process can be traced, supervised and managed
"code chain technology" is the most widely used two-dimensional code "scan" payment technology
code chain technology can realize more efficient link form of people to people, people to things and things to things
Introction to blockchain:
blockchain is an important concept of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
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 paradigm, 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
the difference between code chain digital currency and blockchain digital currency:
the difference between "code chain digital currency" based on code chain technology and the existing blockchain digital currency is that "code chain digital currency" is based on the control of property rights, and uses "intelligent two-dimensional code" as the medium to transform the contracts of various instry chains into divisible, tradable, transferable, exchangeable Traceable "smart contract" and real right exchange within the code chain alliance. In the code chain monetary system, "intelligent two-dimensional code" means "SGR". That is to say, each commodity corresponds to a "smart QR code", and this "QR code" represents the "special reference property" of the commodity. Through special reference to the exchange of property rights, the exchange of goods (barter) can be realized. This two-dimensional code, which represents "special mention of property rights", can be used as the carrier and payment means of digital currency at the same time, and payment can be completed through "two-dimensional code scanning".
Anti counterfeiting traceability system refers to the use of two-dimensional code anti-counterfeiting label information storage encryption features to keep the commodity information confidential, refine the proction process to each key control point, clarify the responsibilities of each key link, and complete the safety and quality management mode of "proction records, process traces". After scanning the QR code, consumers can get the date of proction, place of proction, commodity information, etc., so as to complete the traceability of goods. Two dimensional code anti-counterfeiting traceability system can not only let consumers buy at ease, but also deal with the problem of anti-counterfeiting traceability for businesses
The fourth step is flow detection. Enterprises should input the information of proct logistics management, sub packaging sales and proct warehousing, so as to realize the management mode of responsibility to person The fifth step is terminal sales. Note the procts put into different sales channels, which is convenient for enterprises to view the performance of different marketing channelsthe sixth step is to query the terminal. Consumers can query through four ways: mobile phone query, Internet query, 400 query, query and query
I think the future prospect of blockchain is very broad
1. Blockchain is the only data
because it can uniquely determine an information address. For example, the right of papers is now pirated a lot. We can use blockchain to solve this problem. For example, if Xiao Ming writes a paper, he needs to find a senior expert to tutor the paper before publishing it. If the tutor changes his name to his own name for publishing without permission of Xiao Ming, then Xiao Ming's right will be infringed. This is that Xiao Ming can record a block on the blockchain, The radio tells you that the author of this paper is Xiao Ming. You know, the information address on the block can't be changed by everyone. It protects the right very well
the future development prospect of the above blockchain is very big
since ancient times, "whole purchase, whole sale, whole lease" is a recognized commercial law, especially in the 40 years of reform and opening up, e to various reasons, "property right" is greater than "real right", and the status of "real right" has been artificially reced“ "Property right" can only be transferred and traded as a whole, and the financial security attribute of "property right" has been deprived
the emergence of the property law of the people's Republic of China, especially the legal rules of Chapter 8: common ownership of the property code of the people's Republic of China, has greatly enhanced the legal status of the "common property" and legalized the share based common ownership. At the same time, it is possible to "digitize" the "property" in combination with the background of "digital instrialization and instrial digitization", This will make the property right of small and medium-sized enterprises financialized and securitized to the maximum extent, and make the digitalization of property right become an innovative instry. In the face of tens of trillions of private enterprise "property" volume, "digital" property will usher in a broad space
the property rights of the civil code gives birth to "common property rights", new thinking, new logic and new instry of "digitalization of property rights", which will change the traditional pattern and mode of "proction, life, investment and transaction"< Article 15 of the property law of the people's Republic of China:
the parties shall conclude contracts concerning the establishment, alteration, transfer and elimination of real property rights. Unless otherwise provided by law or agreed in the contract, it shall come into force upon the establishment of the contract; If the property right is not registered, the validity of the contract shall not be affected
this provides a legal basis for the signing of "digital transaction of property rights", "transfer of common property rights" and "smart contract". Because after the "digitalization of real right", the trade fair is very frequent, and the "registration certificate of real right" cannot be replaced frequently. The "contract" is effective, which solves the bottleneck and difficulty of "digitalization of real right"< Article 297: real estate or chattel may be jointly owned by more than two organizations or indivials. Common ownership includes share ownership and common ownership. Article 298 a co owner by share shall have the ownership of a jointly owned realty or chattel according to his share. Article 299 the joint owners shall jointly enjoy the ownership of the jointly owned realty or chattel. Article 300 the co owners shall manage the jointly owned realty or chattel in accordance with the contract; If there is no agreement or the agreement is not clear, each co owner has the rights and obligations of management< In May 2020, the third session of the 13th session of the National People's Congress voted and passed the civil code of the people's Republic of China, which is the first law named after the code in New China. Thirdly, it defines the legitimacy of the transaction of "common real right" and "digital real right" in the form of "code".
