Blockchain differentiated circulation

1. bitcoin is a kind of virtual digital currency proposed by Nakamoto in 2009. It is characterized by no centralized issuing institution and a fixed total of 21 million pieces. It is not a one-time issue and needs to be proced by miners. Due to the decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve
blockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.

2. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid
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.

3. Virtual currency is a kind of blockchain technology. Some countries are legal, such as Japan, Russia, South Korea, etc. 66otc is currently the most fluent, reliable and best used OTC platform

4. The difference between code chain and 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".

5. First, let's look at the application scenarios. Blockchain is created to solve certain applications. The value of a token depends on what problems it is to solve, how big the market prospect is, and what pain points exist in traditional solutions. Can we only use blockchain technology? Is it global or local? Is it public chain or private chain or alliance chain? The wider the scope of general application, the higher the level of pain points to be solved, and the greater the market prospect, the higher its value. For example, ecoball operating system, which is a basic platform of blockchain, can quickly create various blockchain scenario applications, rece the technical and financial barriers for enterprises and indivials to use blockchain technology, and play a good social value and huge economic value

secondly, the management team. In Simultaneous Interpreting with the traditional instry, the main chain is not online, and has not even begun to research and build Token. Whether a blockchain project is successful or not, and what height it can reach, the start-up team is crucial. A good team must include the following types of talents: instry talents, technical talents and operation talents. It can be said that for a good project, these three types of talents are indispensable. The stronger the team strength is, the more comprehensive the configuration is, the higher the token value is

Third, look at the design of token. The value of token is directly related to the total amount of token. The less the total amount, the higher the value. In addition, the value of token is also related to the way of distribution. How to match the token of project side, operation side and fund side? How to design airdrop and incentive? Inflation or deflation? Do you need mining? The time of lock in will also directly affect the value of token. Good blockchain projects will distribute most of the tokens to users. Ecoball's token "ABA" is to award most of the tokens to users who have contributed to the community. When a project party holds a large number of tokens, it is necessary to prevent it from cutting leeks

four aspects of community construction. A key word for the development of blockchain technology is "consensus". The higher the degree of consensus, the better the community construction, and the higher the value of token

five factors are capital strength. Funds are the guarantee for the success of blockchain projects. Whether crowdfunding funds are in place and used as planned, whether there are other financing channels, and whether R & D funds are sufficient are also important factors affecting the value of token

it is revealed that the token "ABA" of ecoball project is currently carrying out the activity of white list. I don't do any promotion here. If you are interested, you can contact the project owner to find out by yourself.

6. Blockchain
is not a single indivial, but many
blocky structures
are connected together to form a chain structure. Then the connection of each block will also form a specific whole or area. So there is no difference between blockchain and regional chain. For more details, please note the official account of
