Third generation blockchain

1. As a kind of decentralized database, blockchain has the characteristics of openness, distribution and irreversibility. As an electronic data storage platform, blockchain has the advantages of low cost, high efficiency and stability. At present, blockchain has been applied in many fields and has brought many changes to our life. Now many electronic contract platforms, such as Fada This kind of blockchain technology has been applied in the chain of evidence, and the blockchain technology has also been accepted by the court

2. The summary is as follows:
in the north, go to
in the south, do not want to go to

now new houses have their own bathroom, so less and less people will go to the public bath
especially the young people are reluctant to go. Generally, the elderly prefer to go. They can chat and take a bath with each other.

3. Blockchain and financial technology have become the hot spots of world investment in recent two years. Central banks and commercial banks in many countries are studying related projects. This is an interdisciplinary research topic, covering finance, computer, law, communication, management, mathematics, statistics, psychology, economics and sociology
the first generation of blockchain is represented by bitcoin chain, and the second generation is represented by ripple and Ethereum chain. These two generations of technologies need to be improved in terms of privacy and scalability, and there is a certain distance from commercial applications of banks, especially in bank settlement and stock trading, which are often mentioned
scholars are developing the third generation blockchain to change the architecture and application scenarios of blockchain. The development of the third generation blockchain will be based on systems engineering, software engineering, cloud computing, big data, computational law and application fields, combined with software, hardware, communication technology and a new application thinking and process
this new thinking is digital society. Gartner Group believes that human beings will enter the digital society in 2016, and blockchain is one of the 10 important technologies in the digital society. This digital society research project will change the financial sector (including banks and exchanges), the legal sector, and even the whole human society
this speech will mention the new blockchain architecture and possible banking application scenarios proposed by Beihang digital society and blockchain laboratory
however, the specific research results are not clear, and now there are many researches on blockchain. There are also many related projects, such as Ethereum, the distributed content publishing platform decent.

4. Dag is also a directed acyclic graph, in which there is no concept of block. The whole flow chart is composed of one transaction. The advantage is that it can save the block and packing process. The advantage is faster, no transaction costs, and no mining
iota adopts DAG technology to build a residential planet of blockchain rental platform, and will also be developed on the basis of iota. Ideally, the larger the network, the faster the transaction confirmation speed of iota, and the more secure the network. The purpose of living planet is to realize the interconnection of intelligent terminals such as intelligent door lock, router, camera and so on.

5. No, maybe some people mistakenly regard bitcoin, the key application of the first generation blockchain, as the blockchain itself, but in fact, it is only an application of the blockchain. At present, blockchain has developed to the third generation
the first generation of blockchain is exchangeable, mobile and encrypted digital asset authentication
the second generation of blockchain is essentially the first generation of blockchain + smart contract
the third generation blockchain is the instry wide application of the second generation blockchain + blockchain technology
what you said is just a narrow sense of application.

6. 1. Using high-performance chain trading to solve the security problems caused by the exchange centralization
2. Comprehensively provide simple and easy-to-use blockchain financial procts, including spot trading, financial lending, digital asset storage and financial derivatives, so as to realize the integration and upgrading of blockchain and traditional finance
3. Introce the regulatory framework of traditional financial securities, such as the issuance of STO securities, implement the third-party asset custody, and become a compliance financial service platform.
