what is Ethereum:

Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want

advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum

what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application

The design of Ethereum is very flexible and adaptable

Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields

blockchain applications of Ethereum

Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc

Ethereum has achieved more than 100 blockchain applications by many start-ups

Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged

the relationship between Ethereum and blockchain:

Ethereum is a programmable blockchain

Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes

in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency

like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"

2. 1. Bitcoin 2, Ethereum: Ethereum is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0".

5. 1. What is blockchain
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 [1]
2. What is a concept
concept has two basic characteristics: Connotation and extension. The connotation of the concept refers to the meaning of the concept, that is, the unique attribute of the object reflected by the concept. For example: "goods are labor procts for exchange.". Among them, "labor procts for exchange" is the connotation of the concept of "commodity". The extension of the concept refers to the scope of the object reflected by the concept. That is, things or objects with attributes reflected by concepts. For example, "forest includes shelter forest, timber forest, economic forest, firewood forest and special purpose forest", which is to explain the concept of "forest" from the perspective of extension. There is an inverse relationship between connotation and denotation of a concept, that is, the more connotation a concept has, the smaller denotation it has; vice versa. A more understandable explanation: the connotation of the concept refers to the meaning of the concept. There are necessary conditions, that is, objective things (objective objects), among which there is only one necessary condition and N sufficient conditions. The more conditions, the smaller the extension of the concept. Conditions are functional. For example: the cup needs space to carry. And it is used to hold water, wine and other liquids. Moreover, it is a kind of utensils (the defined items cannot be directly or indirectly included in the definition items), so the meaning of the concept of cup is: utensils used to hold water, wine and other liquids. And if we know the sufficient conditions, we can roughly dece the things or objects. Because it must be connected with the objective things. The functions of concept include judgment, description, attribute, category, definition (conceptual clarity), etc

the description of concept in China is: concept is avant-garde, novel, trendy, with future trend, background and picture. The concept has the strict fixed content, also has the certain fuzziness. Concept is not real, but imaginary. We should use concept to think and use concept to show its authenticity. The pattern of consciousness is endless. The more thorough the images are, the better it will be for us to enter a fine and infinite field. Otherwise, one thing will always be reced to another
from the perspective of form: ideas are more advanced, concepts appear in the form of words, and ideas usually appear in the form of a complete sentence. But in the same form; They are all based on Chinese and symbols. Therefore, it can be understood that the concept is a brilliant idea that condenses more information. Therefore, the concept is imaginative and pictorial, while the scientific concept is systematic. Concepts must also be comprehensible, so they are universal and objective.

6. Anti counterfeiting research is the problem of "who am I?" it is to identify the unique properties of the goods by means of fingerprint recognition, iris recognition and other methods to ensure their authenticity and uniqueness. The problem of blockchain proct traceability is "where does the proct come from? Where are you going? " For example, vonetracer of wangchain technology, after users get the proct, they can scan the code to see the whole process.

7. 1, comprehensive layout is coming
as people's misunderstanding of blockchain technology graally dissipates, we will see that next year, the financial services, insurance and medical instries will carry out comprehensive deployment of blockchain technology
blockchain technology will subvert our payment system internationally - the old profit model and other processes will become obstacles, and payment will become faster, cheaper and safer
however, as blockchain becomes more and more mainstream, we can no longer ignore the main obstacles on its development path. For example, the banking instry must develop a clear roadmap for blockchain adoption and cooperate on the basis of global standardization
2, the standardization process is about to start
with the more and more extensive application of blockchain, it will become extremely important to establish standardization methods between each other. But there are complex and political processes that can get in the way - there are conflicts of interest between instry organizations, and companies are trying to gain a clear advantage
with the implementation of various blockchain schemes, we will see that the situation will change to the process of standardization and integration. Once competing organizations graally realize the benefits of alliance and start to accelerate the trade process, strengthen detection and optimize data management
in 2017, there may be only a few dynamic blockchain alliances left, but instry players will have to cooperate and reach an agreement on a flexible and universal open logo. Governments and regulators will also play an important role in protecting consumers and encouraging innovation
stakeholders driving the development of blockchain standards will need to be creative and can envision a future in which these standards can be used to create new and powerful tools
3, fintech is accelerating development
fintech is bringing great changes, from simple payment to complex global financial operations are being subverted by it
the in-depth changes that are expected to happen next year are as follows:
blockchain combined with machine learning can jointly accelerate the existing process and optimize efficiency
emojis, payment, will be more widely used, and mobile devices will become more and more secure
lending network will become one of the hottest areas of blockchain
all countries in the world will be more interested in the development of digital currency
4, it's time to subvert the field of payment
in the field of payment transaction, blockchain technology is used to overcome the problems existing in the agent banking system and international remittance
there are many proceres and incoherent processes in cross-border non cash transactions, which can be eliminated by eliminating the third-party institutions, direct currency transfer and efficient inter-bank settlement. This possibility of creating a competitive market for liquidity providers may ensure the optimal exchange rate for international exchange and payment transactions
payment systems are based on local banking regulations and practices, but lack of common standards, which reces the ability of seamless transmission of data and background information, and brings settlement and non settlement risks
the extensive implementation and use of blockchain will change and subvert the existing financial services instry and payment system on a global scale
in addition, although the blockchain was very popular in 2016, there was very little substantive progress. Only coin Ying China and China Post really put it into practice, and other projects just stayed in the theoretical stage.

8. The core significance of the blockchain of four technologies is to establish the credit of all data between the participating parties, establish the trust relationship under the premise of creating unilateral ecological common protection under clear regulations, and then let the miners participate in the realization of credit.
