Dao blockchain

1.

We need to establish data layer, network layer, consensus layer, incentive layer, contract layer and application layer

1. The data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and time stamp

2. The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism

The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes

The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuing mechanism and distribution mechanism of economic incentives

5. The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain

6. The application layer encapsulates various application scenarios and cases of blockchain

, general secretary of the CPC Central Committee, stressed in the eighteenth collective learning of the Central Political Bureau, "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". <

p>

the forward-looking judgment of the CPC Central Committee has brought the "blockchain" into the public view and become the common focus of financial capital, real economy and public opinion

from network power to big data, from media integration to blockchain, the Politburo of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, showing the direction, foresight and foresight of the CPC Central Committee, leading the pace of China's instrial change and economic transformation. This collective study of the Political Bureau of the Central Committee of the CPC, with special emphasis on "blockchain", has opened up an imaginary space for the development and application of blockchain

from the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

these features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry, and realize the cooperative trust and concerted action among multiple agents

2. 1.
the underlying development of blockchain can't be realized with Java
2.
to do the upper development, you only need to dock according to the given open source interface, and then use the language you are good at to develop what you need
3.
now there are many blockchain system templates, you can go to see what development cases there are

3. Now there are many frauds in the digital currency trading platform. For the sake of safety, you'd better ask professionals, because you can't verify the authenticity of what others recommend, so as not to be cheated.

Blockchain is a special network account book. The core of blockchain technology is digital encryption. As early as 1991, a group of young people invented a new set of mutual authentication encryption technology in order not to tamper with the date of electronic documents. By means of cryptography, they concatenated and protected the concatenated text records (also known as blocks)

blockchain stores data in blocks, and each block is queued in strict order to form a "chain". If someone wants to change the content of a block, the unique characteristics of the block will also change, and the following blocks will not recognize it immediately, and the "fake" block will have to break away from the chain

extended data

users all over the world can connect their servers to the blockchain network and become an independent node in the distributed database storage system. Once joined, the node will enjoy the same rights and obligations as all other nodes

therefore, people who carry out services on the blockchain can read and write to any node in the system. All nodes in the world will synchronize again and again according to some mechanism, so that the data of all nodes in the blockchain network is completely consistent

because of the two characteristics of immutability and decentralization. Blockchain is a good solution to the problem of trust in modern commercial society. It has emerged in financial services, Internet of things, public services, social welfare and supply chain management

5. In the field of blockchain technology, Dao refers to the community of distributed autonomous organizations, and block is a blockchain technology community
Dao is a mechanism through which we can use software on the Internet to achieve reasonable economic incentives (allocation of risks / rewards). With Dao, people can coordinate with each other and achieve common goals on a global scale without relying on trust or a third party. Blockchain technology makes this mechanism feasible
the establishment of block community is under the background of the rapid development of blockchain, which is faced with some problems: the mainstream blockchain community focuses on media positioning, has a fickle mentality, pays attention to currency speculation and ignores the promotion and discussion of blockchain technology; After blockchain project financing, they are keen on media PR promotion, and do not solidly develop procts and build technology communities; There is no platform to focus on the development of blockchain technology, open up instry university research and government departments, and construct a complete blockchain ecosystem; There is no fair, independent and powerful third-party platform in the instry, which can objectively reflect the quality and community influence of blockchain project development
block is a community that serves blockchain developers and projects, and promotes the implementation of blockchain technology and applications.

6. The full name of Dao in blockchain is "distributed autonomous organization", which is a kind of organizational structure based on blockchain. It can operate independently without intervention and management through some open and fair rules. These rules often appear in the form of open source software, and anyone can become a participant of the organization by purchasing its equity or providing services
there are many changes in the form of Dao, which can be a kind of digital currency, or a system or institution, such as e- community, focusing on the idea of Dao.
