Blockchain changes the world

1. A federal judge yesterday ruled that the IRS has access to user information on coinbase, the bitcoin and Ethernet exchange. The judgment came into force on November 30, Jacqueline; Scott & Chen 8226; Judge Jacqueline Scott Corley decided to approve the IRS petition, allowing it to investigate any possible tax avoidance in the United States
coinbase said it was aware of the existence of the judgment and would make a formal statement shortly

and the US government is celebrating this victory. Director of the IRS, John J; John Koskinen said:

like other properties, virtual currency transactions are taxable‘ The purpose of John Doe's summons is to ensure that citizens in emerging economies can abide by tax laws and fulfill their responsibilities

the coinbase user information that IRS applied to view was from December 31, 2013 to December 31, 2015. Coinbase said it would try its best to protect users' privacy when it first received the subpoena

as we all know, the attitudes and regulatory policies of countries around the world towards digital currencies such as bitcoin are not the same, and the tax policies of different countries are also different
on October 22, 2015, the European Court of Justice ruled that transactions in bitcoin and other virtual currencies would be exempt from value added tax (VAT). This decision is a major victory for the bitcoin trading community

generally, Japanese people need to pay 8% consumption tax to buy bitcoin on the digital currency exchange. In October this year, it was reported that the Japanese government planned to cancel the consumption tax generated by the purchase of virtual currencies such as bitcoin next spring

since 2015, the IRS has regarded bitcoin and other digital currencies as taxable assets. Recently, the IRS inspector general has been responsible for the Department's gaps in digital currency taxation. The American Institute of Certified Public Accountants (AICPA) has raised similar questions.

2. blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology or a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book, because the account books of all nodes are consistent, and different nodes can trust each other, so there is no doubt about the data, So we all say that blockchain realizes trust technically
based on trust, bumeng has built a digital asset platform, which allows enterprises to issue their own assets. In fact, it is an exploration based on the characteristics of blockchain technology to let these assets circulate freely.

3. A blockchain based world builds trust among multiple parties to a transaction, which does not require them to have private contacts. Our current system uses validation and needs to balance costs. The blockchain world not only makes transactions faster, cheaper and truly global, but also allows each of us to control and track the distribution of our own data
companies like Goldman Sachs, IBM and Cisco, as well as organizations like the world economic forum, the IMF and the Bank of England are experimenting with this technology, which shows that this is not a flash in the pan concept, but a reality
Ethereum, an intelligent contract platform, and decent, a decentralized content publishing platform, are the pioneers of blockchain.

4. Blockchain is just a program mode. The data formed by this program mode is traceable. Compared with other program modes, blockchain programs are more fair, safe and not easy to tamper. It only plays a role in the protection of property rights
it seems that some experts and scholars say that the value generated by blockchain will be ten times that of the Internet. They really disagree with this view. Shanghai is the city with the highest GDP in China and has great development potential. If someone says that the value created by Shanghai will be ten times that of the whole China, what do you think
blockchain is based on network and computer. How can it generate ten times the value of Internet?

5. To be sure, the Internet solves the problem of shortening the space for all kinds of exchanges and transactions, and at the same time solves the problem of certain efficiency. The blockchain solves the problem of trust and fundamentally improves efficiency. Take the government affairs field as an example. After the enterprise information and data are linked to the public service platform of SMIC blockchain in Changsha, the administrative department can immediately verify whether the approval conditions are met after the system authorization and permission, and pass the approval immediately, eliminating many kinds of seal proceres, audit verification evaluation and guarantee processes needed in the past, It also directly reces the repeated calculation of some data and the repeated audit of information.

6.

bus line: Metro Line 3 → fan29, the whole journey is about 15.0km

1. Take Metro Line 3 from Dashi, pass 3 stops, and reach Panyu Square Station

2. Walk about 280m, and reach Panyu Square Station

3. Take fan29, pass 3 stops, and reach Hexian hospital (Qinghe East Road) station (you can also take fan160, fan99, fan68, and Fan1)

7. The ground work is not dangerous, because the air compressor pumps that stop working when they need to be maintained should be maintained when the power is cut. If it is underground, it will not be very dangerous, because it will also stop working when it is maintained, and generally the underground is very safe, and there will be no safety accidents. Besides, the general machines are rarely placed underground

8. In just a few years, blockchain has developed from 1.0 era to 3.0 era. The update of each "era" has brought changes to the world. The development of blockchain can be divided into three stages from 1.0 era to 3.0 era: point-to-point transaction, transaction and transaction Smart contract and blockchain application Ecology (token economy)
blockchain 1.0 era: digital currency rate of return is the king

blockchain 2.0 era: smart contract provides infrastructure support for upper application development

blockchain 3.0: the subversion of business lies in the transformation of proction relations

all obstacles to the development of human society, Fundamentally speaking, they are all caused by "mutual distrust", especially various economic and financial crises. If human beings can solve the problem of mutual trust, then human beings will complete a very big leap forward
the development of blockchain has graally laid the foundation for this direction. Human beings are entering the era of "smart contract", which is the process of upgrading human trust mechanism. Once the smart contract is reached, human society is facing a new big upgrade. As a value creator, the value created by each indivial can be accurately recorded and the corresponding return can be obtained, There will be less and less mutual interference, and people are really moving towards independence and equality. Human civilization has evolved from "identity society" to "contract society", and blockchain is expected to lead human beings to transition from "contract society" to "smart contract society"
although blockchain has gone out of the conceptual stage, the current situation of blockchain technology development is that the underlying technology is not mature enough and the application scenarios are relatively limited. On the one hand, consensus algorithm and other core technologies of blockchain still have room for optimization and improvement; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms are originated from foreign countries. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the global blockchain technology development. It still needs a certain period of time. It can be said that the whole domestic trend is waiting for the emergence of a super level blockchain project
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
