Blockchain did distributed identity

1. 1. What is the technology of blockchain?

2. Specifically, the ID card and driver's license information entered by the user will be verified. The ID card and driver's license information that have passed the verification will be identified as valid, and the ID card and driver's license information that have not passed the verification will be identified as invalid. For more wonderful application problems, you can pay attention to the central area chain service platform for real-time understanding

3. Satoshi Nakamoto, who calls himself Japanese American, is the creator of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm called "bitcoin". In 2009, he released the first bitcoin software and officially launched the bitcoin financial system. In 2010, he graally faded out and handed over the project to other members of the bitcoin community. Nakamoto is believed to hold about one million bitcoins.

4. In the blockchain, jinwowo Group believes that the public key and private key are used to identify the identity
public key and private key can also ensure the security of new point-to-point transmission in distributed network
in the information transmission of blockchain, the encryption and decryption of the public key and private key of both sides of the information transmission are often not paired.

5. Users get bitnation & quot; through blockchain on their official website It has a significant impact on the identity authentication system

6. You should fill in your personal identity information, real name system, nickname, mobile phone number, Alipay, face sweeping, and you need to pay one yuan to verify your identity.

7. Blockchain can be traced. This technology is used in many fields. Many enterprises will use this technology to detect the source of goods, so that consumers can rest assured
the information in the blockchain can not be tampered, that is to say, the information recorded on the blockchain can be used to achieve the goal of traceability as long as the source is correct
in general, this technology is mostly used for commodity traceability, and the blockchain traceability technology can be understood in cryptography.

8. Bitcoin market suddenly soared, and now you can buy it. But you have to buy by yourself. Think about it, because bitcoin is a virtual currency. Market uncertainty, buy carefully.

9.

At present, with the rapid development of science and technology, the situation is surging. If you and I are a little lazy, we may be out. No, the new blockchain is coming. Since the beginning of this year, blockchain has become one of the hottest knowledge points in the field of science and technology, and has become increasingly prominent in the fields of digital finance, Internet Governance and big data computing

blockchain technology also has broad application prospects in the military field, which is very likely to quietly subvert the future war

this is not Xiaole's boasting“ There is nothing more important about the three armed forces than secrecy. " We should know that in the future information battlefield, confidentiality is the key to win or lose the war. Because the blockchain system has many characteristics such as information independence, confidentiality and integrity, it can realize the perfect combination of data storage and data encryption. After being attacked, it also has strong recovery ability, and can protect highly sensitive data, which is of great help to win the war

according to the information collected by Xiaole, some countries are planning to build blockchain information platform and begin to study the application potential of blockchain in several scenarios such as military satellites and nuclear weapons; An international organization is currently evaluating the performance of blockchain technology in military logistics, Internet of things and other fields

if bitcoin and other digital currencies are blockchain 1.0 applications, blockchain 2.0 is the "smart contract" that provides a strong guarantee for network transaction data security. There will be 3.0 in the future, from Dao (blockchain self consistent organization), DAC (blockchain self consistent company) to blockchain society

"cultivate new kinetic energy with informatization, promote new development with new kinetic energy, and create new brilliance with new development." I believe that blockchain, the "new kinetic energy" of science and technology, will bring us more surprises: "one machine in hand, I have it in the world", "trade autonomy", more extensive sharing, and the optimal life mode... Blockchain technology will create a more honest, convenient, and efficient Era of big data

10. 1. Block identity is the user's pass in TTC ecological community, which is bound with block identity ID
the block ID is equivalent to the QQ number in Tencent proct ecosystem. The differences between the block ID and QQ number are as follows:
a. the user's personal data will be stored in their respective block address, and the user can login through the block ID for management. b. Block ID is developed based on blockchain technology, which has the characteristics of decentralization, distributed accounting, anonymity, security and controllability of blockchain
2. Block ID is the pass of TTC ecological community, which can be used to log in to all applications in TTC ecological community with one click, including various dapps launched in the future. There is no need to register repeatedly, so it is more convenient to collect and pay. Now there is a six digit number for registration.
