Code chain to blockchain
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".
① entry fee (whether to pay the capitation fee): whether it is necessary to subscribe for goods or pay fees to obtain the qualification to join or develop the qualification of others to join, so as to seek illegal interests
② pull the head (whether it is necessary to go down the proction line): whether it is necessary to develop others to become their own proction line, and pay the developed personnel according to the number of their direct or indirect rolling development, so as to seek illegal interests
③ payment method (whether rebate at different levels): whether the payment is calculated on the basis of direct or indirect development personnel to seek illegal interests
2. According to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk
warm tips: the above information is for reference only. Before investing, it is suggested that you first understand the risks existing in the project, and understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market
the above information does not constitute any investment proposal, and investors should not use such information to replace their independent judgment or make decisions only based on such information, which does not constitute any trading operation
digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

What is blockchain? What kind of changes will it bring to the future life
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. It is essentially 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 the information of a batch of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
in fact, the word blockchain does not appear in the original English version of bitcoin white paper, but the word chain of blocks. In the earliest Chinese translation of bitcoin white paper, chain of blocks was translated into blockchain. This is & lt; Blockchain & quot; This Chinese word first appeared
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services, which will come into effect on February 15, 2019
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography
In the end, this is undoubtedly a new life changing technology. In the future, the proction activities of the whole society will be carried out with blockchain as the underlying logic. Many things are within our reach. With the integration of artificial intelligence and big data, we can easily handle the seemingly complicated things, For example, some securities market transactions and intelligent matching of financial activitiesit's easy to understand that blockchain is the integration of people, property, man, machine, material, man, field and goods, which is packaged into a whole; A network computing center that runs on an infrastructure
