Blockchain chess mahjong
blockchain technology is widely used. Under the integration of new technologies, the main application scenarios of blockchain include finance and insurance, intelligent manufacturing, intelligent environmental protection, energy and power, health care, ecation, culture and innovation, smart city, social welfare, agriculture and many other fields
-
blockchain + finance
blockchain can help financial institutions solve problems such as trust and data sharing
-
blockchain + right art

3. Blockchain + government
in statistics, voting, budget management and other aspects, blockchain can rece costs, improve efficiency, and increase transparency, so as to prevent the risk of failure of centralized system
4. Blockchain + insurance
fraud identification and risk prevention: by placing insurance claims under an unchangeable general ledger, blockchain helps to eliminate the common sources of fraud in the insurance instry
property insurance and accidental injury insurance: policies and shared ledgers recorded in the form of smart contracts can improve the efficiency of property insurance and accidental injury insurance
Health Insurance: blockchain technology enables medical records to be encrypted and shared among health service providers, thus improving the interoperability of the health insurance ecosystem
Reinsurance: the information security of reinsurance contracts on the blockchain platform can be ensured through the form of smart contracts, which can rece the amount of information and simplify the payment process between insurers and reinsurers
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.
The most important reason why blockchain is questioned is that there is no practical application scenario, and ordinary people can't see the possible value. In the eyes of these experts, where are the most likely application scenarios of blockchain
Shuai Chu, the founder of quantum chain, said: at present, the evolution of the whole blockchain technology is still at an early stage, just like the Internet era 20 years ago. At that time, we could not imagine that there would be applications like Uber on the Internet. The development of technology would give you more diversity. The possibility is the future According to the technical characteristics of blockchain, Zeng Ming, Dean of Hupan University, gave several possible answers:1. The most important advantage of blockchain is transparent, unchangeable and distributed ledger. Some areas have never been covered by the Internet, such as acceptance bills
2. Another big advantage of blockchain is that from the perspective of smart contract, it is possible to form more efficient network collaboration at the point-to-point level. Like crowdfunding
3. In the field of innovation, blockchain will definitely be closely combined with the development of Internet of things, artificial intelligence and other fields, including cloud computing, edge computing and so on
Xinhua News Agency's "Xinhua viewpoint" reporters Song Jia, Liu Juan, Ke Gaoyang
"rampant bombardment of SMS and phone calls", "it's hard to go without signing an agreement, people follow me to the toilet", "it's said that the degree is undergraate when recommending, Recently, many matchmakers have complained to "Xinhua view" reporters. Some matchmaking agencies that have opened online platforms have launched online and offline "bombing" sales, "kidnapping" contract signing, "and" make up "services, which have seriously damaged the rights and interests of consumers
the "bombardment" of phone messages continues, and the marketing staff are trapped for hours when they don't sign a contract when they arrive at the store.
many blind date people report that they have registered their blind date platform account at random, which leads to the "bombardment" of phone harassment and the nightmare of going to the store without buying a service
Mr. Li from Guangdong said that he received phone calls and short messages from the platform to invite him to the store just after registration. It's no use refusing to blackmail every day, but there will still be new numbers calling in“ They have always stressed that there are female members who are very interested in reading my information, but actually I didn't fill in anything in my personal information. "
the reporter registered their accounts on several love and marriage platforms with their mobile phone numbers, and received an invitation call from the sales staff on the same day. Since then, the reporter will receive more than 10 calls and text messages to the store every day. When the reporter said it was inconvenient to answer the phone, the other party would continue to harass later
"as long as you don't agree to go to the store or confirm the interview time, the other party won't hang up." Shenzhen's Ms. Li said, unbearable harassment, had to choose to go to the store to see. I didn't see the "matching" object, but I was "trapped" for more than 4 hours, and even went to the toilet with someone. In the sales staff's hard and soft, Ms. Li was finally inced to open the online loan, bought 28800 yuan blind date service package
the reporter visited several offline stores of love and marriage platforms as a blind date“ You'll see the match we screened for you later, and we'll communicate. When you sign a contract at the store for the first time, I can also help you apply for VIP service, which costs 16500 yuan and 28800 yuan. " A staff member who claimed to be "the top three in the success rate of blind date in the store" played a "preferential card" to persuade the reporter to sign a contract, and asked and checked the reporter's Huabei, credit card limit and repayment on the grounds of credit inquiry. He also hinted to the reporter repeatedly that he would open online loans such as jiebei to buy service packages
when the reporter said that she had no intention of signing a contract, she called the so-called superior "manager" and kept the reporter in the room to continue to sell under the guise of scoring the service. The reporter said that she wanted to go back to discuss with her family. She asked the reporter to call directly at the scene; The reporter said that she was hungry and wanted to leave to have something to eat. She said that she would order the takeout immediately and send it in... The reporter asked to leave several times, but she stopped her for various reasons. The interview lasted for more than four hours
"a member once stayed with us for 11 hours, followed us from morning to night, and finally signed." Century Jiayuan, a marketing staff said
consumption trap: pay and sign first to see if the contract, service and commitment are inconsistent
search the name of blind date institution on online complaint platforms such as "gather complaints" and "black cat complaints", and more than 2000 complaint cases have been found. The reporter found that the main problems that caused the complaints focused on inced consumption, Overlord terms, service inconsistent with commitment and so on
- the contract can only be read after paying and signing. Many complainants said that they did not see the contract before they paid. Some organizations are not allowed to see the contract without paying or signing; Some consumers are inced to sign electronic signatures, but they don't know what they are signing
"before signing, the marketing staff didn't mention the contract, and I didn't see the contract." Mr. Li told reporters that he was asked to enter his personal information on the iPad, fill in his mobile phone number and verification code, and then jump directly to a separate page with only the signature column
Ms. Wang from Sichuan also reflected that she was not allowed to see the contents of the contract when signing the contract, but took away the paper contract after paying for and signing it. She only received an electronic contract a few days later
- the oral promise is inconsistent with the contract terms. After receiving the E-contract, Mr. Niu from Zhejiang found that the terms of the contract were different from the commitment of the marketing staff. Not only the number of introcers was reced from five to three, but the service cycle was also changed from three months to two months“ I asked her what was the matter, and she said that she would fulfill her oral promise later. But after the service started, I changed several staff members back and forth, and finally it was e in two months. No one cared about me. "
- the terms of the contract do not match the subsequent services. According to Ms. Li's contract, the monthly income of the seven blind dates introced is between 20000 and 40000 yuan, of which three have houses in Shenzhen and four in other places“ I met with one of my blind date and chatted with him. He didn't have a house and his monthly salary was just over 10000 yuan. It's not what the contract says at all. "
Ms. Wang in Hangzhou was frequently informed to change her blind date“ It felt like a makeshift. When I recommended it, I said it was a bachelor's degree. As a result, I found it was a junior college after I met. " Wang said< According to Qiu Baochang, head of the law group of China Consumers Association, the consumer protection law stipulates that business operators are not allowed to send commercial information to consumers without their consent or request. Consumers can complain to the market regulatory authorities about the phone text message harassment of blind date organizations and dissuading blind date people from leaving the store. If you don't sign a contract and don't let go, you can call the police if necessary
in view of the consumption trap of matchmaking agency market, Hou Guoyue, a professor of civil and Commercial Law School of Southwest University of political science and law, believes that fairness is the basic principle of contract law, and the unequal and unfair terms set by matchmaking agencies in standard terms should be invalid. It is suspected that it is illegal for the blind date agency to ask the parties to sign on the iPad without seeing the specific terms of the contract and being informed of the specific content and price of the service. The parties have the right to terminate the contract and request a refund of the fee
"if a blind date claims afterwards that he or she does not know the content of the contract, it is often difficult to provide evidence, which is also an important reason for the difficulty in safeguarding his or her rights." Hou Guoyue reminded that blind date people should strengthen their awareness of legal risk prevention and enhance their ability of self-protection
according to Liu Junhai, a professor at Renmin University of China, some intermediaries attach great importance to development rather than standardization, and when they receive complaints, they often evade their responsibilities on the basis of "platform exemption", resulting in no way for consumers to complain
the reporter learned that the matchmaking agency, as a business entity, is registered by the market supervision department, and the matchmaking service needs to be approved by the civil affairs department. Experts suggest that the Civil Affairs Department, together with the public security and market supervision departments, should establish a department cooperation mechanism to form a supervision force.
as for the cost of blockchain technology applied to the development of chess and card games, we can refer to the usual. Of course, with the increase of blockchain technology, the development cost will increase rather than decrease. At present, in the development of blockchain technology, Yingtang Zhongchuang is relatively reliable, and the developed chess and card game solutions can solve many problems.
Blockchain is an emerging technology based on the Internet. The emergence of blockchain has greatly guided the change of proctivity and proction relations. As the most promising blockchain application, blockchain game is known as the killer application since the birth of blockchain technology. Since the end of 2017, the world's first blockchain game has won great support in the market as soon as it came out. Since then, blockchain games have become popular in the whole network. Whether it is the Internet instry or the blockchain instry, the game has a place
with the great enrichment of people's material life, the disadvantages of traditional games are graally emerging:
e to the centralized structure, the fate of game players is almost in the hands of game companies. Game companies can adjust the established rules of the game by modifying various data and parameters, thus damaging the interests of players. At the same time, e to the closed influence of different games, players can not freely control the hard-earned equipment. At the same time, they can rarely carry out cash operation. Based on the above reasons, bit Three Kingdoms was born
blockchain technology still has huge development space, and blockchain game also has great development potential. For bitthree, the exploration of blockchain game has been in the forefront of the instry, and will lead the development of the blockchain game instry
if serial protocol is used, TTL data line must be connected to the specified TTL data line interface of router first,
and then the connection rate of router CPU must be known so as to set,
of course, you also need to know which serial port your TTL data line occupies
