1. 1. What is the technology of blockchain?
2. There are few real baas that have been approved by the state. At present, the mainstream platforms are Tencent's tbaas, Jingdong Zhizhen chain jdchain, ant blockchain baas, Rongze's rbaas, network's Intelligent Cloud and Huawei's cloud BCS. Among them, the top four baas platforms are teams that have been researching and developing blockchain technology for several years, R & D capabilities are very strong.
3. How to operate the isolation witness? In fact, it's not so simple ~
isolation witness is a method of blockchain expansion, which has been successfully implemented on lightcoin and bitcoin
at present, each block in the blockchain not only records the specific information of each transfer transaction, that is, at which time point the account receives or transfers out how many bitcoins, but also contains the digital signature of each transaction, which is used to verify the legitimacy of the transaction. The miner needs to verify each transaction one by one with digital signature when packing the block. After confirming that there is no problem, the transaction will be recorded in the block
however, for ordinary users, they only care about the number of assets in each account, and do not need to verify each transaction one by one. Isolation witness is to take out the digital signature information in the block, so that each block can carry more transactions, so as to achieve the purpose of expansion.
4. 1. Public chain, no official organization and management organization, no central server, participating nodes freely access to the network according to the system rules, not controlled, and work based on consensus mechanism among nodes Subversive: absolutely credible and open) < br > typical case: digital currency represents bitcoin < br > 2. The private chain is built within a group. The operation rules of the system are set according to the requirements of the group, and the modification or read permissions are limited to some extent, while maintaining the authenticity and partial decentralization of the blockchain Typical case: R3 < br > 3. Alliance chain, jointly initiated by several institutions, is between the public chain and the private chain, and has the characteristics of partial decentralization. The read permission on the fast chain in this area may be public or partially public, that is to say, multiple pre selected nodes are designated as bookkeepers internally, and the pre selected nodes compete for bookkeeping permission, Other access nodes can participate in the transaction, but not the accounting process The abilities of the candidates should not be uneven< Br > (relatively credible and open) < br > existing cases: Super ledger < br > example:? In the case of loan diversion, when the user jumps to the other party's website for registration through our link, the docking party can choose to cheat and say that it has not received the user's registration request. However, if we put the user registration behavior into the block, if the docking party wants to receive the user registration behavior, it must pay us at the same time.
5. The common point between AI and blockchain
blockchain focuses on keeping accurate records, authentication and execution, while AI helps to make decisions, evaluate and understand certain patterns and data sets, and ultimately proces autonomous interaction. AI and blockchain share several characteristics, which can ensure seamless interaction in the near future. Three main features are listed below
1. AI and blockchain need data sharing
distributed database emphasizes the importance of data sharing among multiple clients on a specific network. Similarly, AI relies on big data, especially data sharing. The more open data available for analysis, the more accurate the prediction and evaluation of the machine, and the more reliable the generated algorithm
2. Security
when dealing with high-value transactions on the blockchain network, there are great requirements for the security of the network. This can be implemented through existing agreements. For artificial intelligence, the autonomy of the machine also needs high security, in order to rece the possibility of catastrophic events
3. Trust is a necessary condition
for any widely accepted technological progress, there is no greater threat than the lack of trust, and artificial intelligence and blockchain cannot be ruled out. In order to make the communication between machines more convenient, we need to have an expected trust level. In order to execute certain transactions on the blockchain network, trust is a necessary condition
the impact of blockchain and artificial intelligence on ordinary people
in short, blockchain is a community-based technology, which can make value exchange more secure. Blockchain is just like its name. Each block contains an encrypted transaction record. The blocks are arranged in chronological order, and the security is guaranteed by a cryptographic system. Blockchain is a technology that can change rules, and its emergence is a revolutionary innovation
there are many functions of blockchain, and the specific application is also very wide. For example: if blockchain is used in the food instry, people will no longer worry about eating harmful food. If blockchain is used for diamond proction, consumers will no longer have to worry about buying fake diamonds. If the blockchain is used in the ecation instry, intellectual property protection can be strengthened. If the blockchain is used in the insurance instry, it can alleviate the information asymmetry of the insurance business and help to improve the security of the insurance business
the impact of blockchain and artificial intelligence on ordinary people is enormous. Just imagine, if blockchain and artificial intelligence are combined, will their role expand? Yes, the combination of the two can really have more impact to change the lives of ordinary people
blockchain and artificial intelligence are two extremely important roles in the field of technology, which bring convenience to our proction and life. If we find an intelligent way to make them work together, the impact of their interaction is unimaginable. This is also the core of OMT. After the combination of these two technologies, the future application scenarios are revolutionary and exciting. In the new ecological construction, data storage, sharing mechanism, platform problems, security problems, etc. can be overcome by using each other's technologies. OMT will create maximum value for global users and enterprises and bring more convenience to ordinary people through blockchain + artificial intelligence technology
the answer is over, hope to adopt, thank you!

Digital currency generally refers to bitcoin, lightcoin, Puyin, dogcoin, Ethereum and other digital cryptocurrencies

However, as early as December 5, 2013, the five ministries and commissions of the CPC Central Committee jointly issued a document to guard against bitcoin, which is not protected by law, and the Central Bank of China does not recognize its status

therefore, if there is no such statement as China's Internet of things digital currency, it can only be said that there is Internet of things digital currency operating in China

7. mining is the most direct way to get bitcoin. The way to get bitcoin by calculation is mining. If you have a better graphics card, you can go to http://btcchina.net Download the mining client. I believe you know how to do it.
8. Yingchi Hall of fame is the top non-public graphics card. Although the time of silent frequency is similar to 1060, the ability of overclocking is much stronger than 1060. The official power consumption is 165W, while 1060 is 120W. After overclocking, the power consumption will be higher. Pay attention to whether the power supply is enough. The price of 900 yuan can be bought, but please note that if you play a stand-alone game, it may explode in some games. As for mining, so to speak, there is no ore card in the 9 series, and the N card mining was started on a large scale in the 10 series. It may have been before, but it's too few. Before the 10 series, they used to dig with a-card.
9. Strictly speaking, he has a bachelor's degree and a master's degree in physics from the National People's Congress of China. In an interview, he said that after seeing this concept in American TV series, he went to know about his later work in this field. But in fact, I think before he entered the blockchain field, he was responsible for search engine technology and co founded douding.com at Yahoo, which paved the way for him to enter the blockchain field, both technically and operationally.
