1. 1. What is the technology of blockchain?
2. There are many consensus mechanisms in the blockchain. The advantage of the pow consensus mechanism behind bitcoin, the most influential one, is that it is secure and can not be tampered with. The disadvantage is that it is too slow to process only seven transactions a second
3. 1. Pow (proof of work) workload proof
one sentence introction: the more you do, the more you get
2. POS proof of stake
in a word: the more you hold, the more you get< Pbft: practical Byzantine fault tolerance
3. Pbft: practical Byzantine fault tolerance
Introction: it provides (n-1) / 3 fault tolerance on the premise of ensuring the activity and safety< Dbft: Byzantine fault tolerant algorithm authorized by delegated BFT
Introction: dbft mechanism adopted by ant is that bookkeepers are selected by rights and interests, and then bookkeepers reach a consensus through Byzantine fault tolerant algorithm
5. Pool verification pool
is based on traditional distributed consistency technology and data verification mechanism
chainnova is a blockchain company. I feel it's very good. Although I don't know any hash algorithm, I still know a little bit.

4. The analysis of jinwowo network is as follows: because the exchange between nodes follows a fixed algorithm, so the counterparties do not need to make the other party trust themselves through public identity, which is very helpful for credit accumulation.
5. On October 22, 2013, Qiao from Dongyang searched GBL company, a bitcoin trading platform, on the Internet, and recharged 90000 yuan to buy and sell bitcoin through a third-party payment. On October 26, Qiao found that the staff of the network trading platform were not online, and some normal trading proceres could not be implemented, and then reported the case to Dongyang Public Security Bureau
Dongyang Public Security Bureau of Zhejiang Province immediately started the investigation and found that Qiao was not the only one who suffered losses. Through efforts, the police of the special task force determined the identity of the manager of the GBL trading platform and implemented the pursuit in time. The first case of fraud on bitcoin trading platform in China was solved
lawyer analysis:
Zhang Yanlai, senior special researcher of China e-commerce research center and lawyer of Zhejiang Jin law firm, believes that virtual currency is not a new concept. Q-coin and online game currency have long been known by people. However, the emergence of bitcoin once again makes people realize the power of virtual currency. Compared with the traditional q-coin, the biggest feature of bitcoin is that it does not have a unified issuing agency. The generation of bitcoin completely depends on computer algorithms, and anyone can participate in the issuance of bitcoin
this makes it difficult to trace the source of bitcoin, which makes it a real virtual currency. The anonymity, cross-border and other Internet genes of bitcoin make people see a new form of currency that may circulate in the future society, so the pursuit and use of bitcoin also continued to rise in 2013. Some foreign governments have recognized the legal status of bitcoin. In China, some online stores have begun to use bitcoin for trading. Restaurants that accept "bitcoin" consumption have appeared in Beijing. The first "bitcoin" investment fund in China is also being raised. After the Ya'an earthquake, one foundation has received a total of 65 bitcoin donations, with a market price of about 50000 yuan
of course, money laundering, fraud, gambling and so on will follow. This case is a typical case of fraud under the banner of bitcoin trading. As the first case of bitcoin fraud in China, the public security organs have also concted in-depth study and understanding of the professional knowledge related to bitcoin, and finally cracked the case. On December 5, 2013, the people's Bank of China, the Ministry of instry and information technology and other five ministries and commissions issued the notice on prevention of bitcoin risk, which first made it clear that bitcoin does not have the status of legal tender, and required financial institutions and Payment institutions not to price procts or services with bitcoin. The central bank believes that there are three risks in bitcoin Trading: high speculative risk; High risk of money laundering and being used by criminals or organizations. In the future, the future of bitcoin is not clear, especially in sovereign countries, which will take a prudent and conservative attitude towards currency, which involves financial order and national security. Therefore, the public should also raise enough risk awareness.

6. Is bitcoin the most anonymous blockchain asset? What is the strongest
the second major feature of blockchain assets is anonymity. That is, no one else can know how many blockchain assets you have and with whom you have transferred money. There are different degrees of anonymity
the anonymity of bitcoin is the most basic. You can only find transfer records on the blockchain network, but you don't know who is behind the address. However, once you know the person behind the address, you can find all the relevant transfer records and assets. The anonymity of dascoin and Monroe coin is higher. Even if you find out who is behind the address, you can't know all the transfer information
and zcash achieves the utmost anonymity, only the person with the private key can find all the transfer information.

7. You're totally wrong about that<
there is no need for an exchange. The exchange is used for currency speculation, not for payment.
there is only a list of collection addresses. You don't know who the payee represented by the address is because there is no server record, so you can't find who received the money

8. Chongqing jinwowo analysis: because the exchange between nodes follows a fixed algorithm, the data interaction does not need trust (the program rules in the blockchain will judge whether the activity is effective).
9. Because the exchange between nodes follows a fixed algorithm, and their data interaction does not need trust (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to let the counterparties generate their own trust by disclosing their identities, which is very helpful for credit accumulation.
10. Because the trust between users comes from mutual trust in the whole system, there is no need for mutual trust between users, so blockchain technology can provide anonymity similar to cash transactions.
