Can blockchain find people

2. The blockchain can find the transaction direction and address, but you can't confirm who the address belongs to, which means that it is an anonymous and non lost item. Moreover, bitcoin transaction is irreversible, so it can't be recovered after being stolen

3. Blockchain is a public account book. You can't say that your natural gas and chopsticks violate the law, because they are just tools
Chinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.

4. Blockchain? Do you mean blockchain technology or blockchain information, or things related to the blockchain instry
1) if it's just "blockchain", the direct network can find a good interpretation of "blockchain network"
2) if it is "blockchain technology", the network also has a good interpretation, and all walks of life are also trying to combine with blockchain technology in new fields. Maybe in the future, blockchain technology will be used correctly instead of being used to deceive people
3) if it is "blockchain information", you can go to all kinds of blockchain media or financial media, and almost every day there are relevant blockchain instry information and news reports. Such as: Babbitt, coin you finance, blocknet, golden, daily, etc
4) if it's "blockchain audio", you can go to Himalaya FM, litchi micro class, qianchat and other platforms. For example, the audio related to "voice of money", "Yu Lingxiong", "Wang Feng" and some other financial media blockchain is also good, with various dry goods and in-depth analysis
therefore, the above four points are all related to blockchain. It depends on your choice.

5. It can be searched directly on the Internet, and there should be a network library. If you want to see a more complete cvsource where you can download the data of your investment, there is a research report database, which includes other databases besides blockchain, but it seems that it can't be downloaded.

6. From my understanding, blockchain is a kind of "consensus" implementation technology. Through blockchain, all transactions between the Internet can be recorded, which can be witnessed by users of blockchain to achieve "consensus", and the information content on the chain "cannot be tampered with". This "non tamperability" increases the cost of malicious tampering through the existence of multiple copies in the system. In the case of bitcoin, all the highlights in the figure below represent a consistent set of books. Therefore, when all the records are publicized, the problem of "two tables are not measurable" in real life is solved. The reason why the two tables can't be measured is that there is no center and the values of the two tables are different. But the center is not necessary. When there are multiple tables, and the majority pointer points to a time, the minority is subordinate to the majority, the viewer will know. Therefore, a problem to be solved by blockchain is that "the minority is subordinate to the majority". The existence of the minority may be the error of data generation or malicious tampering content. That is to say, if you want to tamper successfully, you must change 51% of the copies in the system [that is, 51% attacks], from a few to a majority. It can be imagined that the cost of tampering is huge in terms of technical difficulty, time consumption and personnel use. At the same time, another key combination of blockchain is the combination with smart contract. Because the former has achieved the "original" of the contract content, the latter has become the "Observer" to execute the contract by machine, which has eliminated the breach of contract and interruption of execution. From the earliest payment to the high development of financial derivatives, financial activities are all behind the signing and execution of contracts. At the same time, the vast majority of financial innovation is to ensure the implementation of the contract and default payment. If the signing of the contract becomes flat and implemented, the whole process will be more concise and efficient, which is a premise that blockchain will be valued by the financial sector.

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

8. If you contact the owner directly, even if you pay more maintenance fees, it's better than you toss back and forth
