Will blockchain steal user information

1. 1. blockchain is an anti tampering, shared and traceable distributed ledger technology. Anti tampering lies in that the modification of a single node can only be recognized through the consensus of other nodes; Traceability means that the whole account book of the blockchain can only be written in, not deleted, and all modification records will be left marks on the whole chain; Sharing means that the account book of the whole blockchain is transparent to multiple nodes in the distributed network
hash function in blockchain is the key to anti tampering, and hash algorithm is a one-way cryptographic mechanism to ensure that transaction information is not tampered in blockchain. After receiving a piece of plaintext, hash algorithm will transform it into a short and fixed hash data in an irreversible way. So block association has but is not limited to tamper proof
2. Quantum secure communication is divided into quantum cryptography communication, quantum teleportation and quantum dense coding. It can be divided into classical communication and quantum communication. The former mainly transmits quantum key, while the latter can be used for quantum teleportation and quantum entanglement distribution. When quantum communication is eavesdropped, although the eavesdropper can't get the information, the communication is interrupted, which affects the normal communication. His anti eavesdropping is at the cost of interrupting the communication, so it doesn't seem as good as the legend.. At present, there are still many unsolved problems in quantum communication, such as short transmission distance, relay difficulty and so on
3. In secure communication, technology competition and complementarity are mutual reference and common development. In secure communication, blockchain should belong to network layer, and quantum communication should belong to physical layer. Therefore, there should be no competition result of who will replace who.

2. Can solve, bit box is a good application proof

3. The core of blockchain + is to graally eliminate all instries that need intermediary to do trust. At present, many central nodes and service platforms of the Internet are essentially trust mediators. Users can do shopping, traveling, ordering, paying and so on through the trust intermediaries such as Taobao, Didi, excellent step, American group, Alipay and WeChat payment.

but the Internet has never been static, and continuous evolution is the norm. In the future, people will have new trust dependence. Because the records of the blockchain can not be tampered with and are authentic, people's trust in the blockchain graally exceeds that of the centralized company. With the joint efforts of many blockchain enterprises and some traditional instries, the world will graally transition from a centralized trust driven to a system driven by algorithms and data. When the centralized trust intermediary is graally weakened, the system represented by blockchain will graally take over the operation mode of the whole world, and finally form the "disintermediated" system trust
therefore, blockchain is not only a technology, but also a story about the paradigm shift of world operation. Although the story is still a little far away, it has sprouted and initially developed

blockchain Internet will start from the instries most closely related to trust and traceability, and graally expand and expand until most instries are blockchain oriented and blockchain +
Puyin is a high-quality Tibetan tea asset, which is stored, identified, evaluated and authorized by three parties. It is a standard digital currency issued through encryption and digitization. Puyin implements the concept of "white paper on standard digital currency" in strict accordance with its operation guidelines, and sets a standard for asset digitization

1. One ruble equals 100 Gobi

2. 1 Russian Ruble = 0.1238 RMB

then 1 Gobi = 0.001238 RMB

above is the currency exchange rate query

5. A new type of blockchain has been developed to make the public transactions used for verification contain only part of the information
Cooper takes interest rate swap as an example. Dodd Frank requires both parties to record 140 data fields. However, in the blockchain, other banks can only see specific data points, and they may just display the code of transaction nature and price range
at the same time, the blockchain will store complete transactions, which can only be seen by relevant parties and regulators with monitoring obligations
of course, the most important thing about blockchain is that it can not be tampered with, and the protection of intellectual property rights is very important, such as the recent foreign project of decent, which is a distributed content publishing platform.

6. No. Now the communication instry is developed, but personal information leakage is serious. It's normal to have such worries, which shows that people's self-protection awareness has improved. But the proct source chain is a high-tech, using the blockchain encryption technology, will completely encrypt the user's personal information, protect the security of the user's personal information, so, don't worry about this.

7. All software operators may disclose the privacy information you submit. The larger the scale, the stronger the security measures, the better.

8. As long as you don't download software, install software, install things, download things in any inexplicable place, and don't enter the account password and verification code in any open page, you won't be poisoned and divulge information. Don't be stupid enough to enter the account password of anything in other people's place. Many frauds fake other landing pages and mistakenly think it's another landing address, For example, make a fake network landing page, input your network account password on it, don't be stupid enough to log in anywhere else, you won't be poisoned, don't install things, don't download things
