Mahjong is the most popular blockchain
in China, the other one I know is the network mutual aid blockchain, which represents the platform of concentric mutual aid. Blockchain technology is used to solve the shortcomings of the network mutual aid instry. At present, blockchain is also very popular in the network mutual aid instry.
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.
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
both eurocrowdfunding and Ethereum use blockchain technology.
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
economic law is subordinate to natural law
according to the length of its historical period, it can be divided into: the common economic laws that play a role in all social and economic forms. They are the embodiment of the common essence of the economic movement process in all human social and economic forms. For example, the proction relations must be suitable for the laws of the nature of proctivity. The common economic laws that play a role in some social and economic forms are the embodiment of the common essence of the economic movement process in some social and economic forms, such as the law of value. They are the embodiment of the special essence of the economic movement process in a certain socio-economic form, such as the law of surplus value in capitalist society. The special economic law that plays a role in a certain stage of a certain social form, such as distribution according to work, is the special economic law in the first stage of socialism, that is, the Communist society
