When marriage meets blockchain
blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code
extended data:
the evolution mode of blockchain is as follows:
& 9642; Blockchain 1.0 - digital currency
▪ Blockchain 2.0 - digital assets and smart contracts
▪ Blockchain 3.0 - Implementation of distributed applications in various instries
blockchain features:
1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work
The information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit
blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".
in today's life, many people use this pretext to cheat, such as direct selling, capital, technology, etc. There is no right or wrong in technology, but in people
with the progress of the times and society, the beginning of the application of any technology will be questioned positively and negatively. However, with the relative application and maturity of technology and the improvement of technology, the various applications around people will continue to improve. I believe that in the near future, these doubts will graally dissipate
the following is a summary of some blockchain scams around us
trap 1: block chain is the coin trap
trap two: virtual currency transactions, promise low investment, high return
trap three: centralization can solve all problems
trap four: block chain extension procts can be laid down with a mining machine to earn money
trap five: WeChat, Alipay trading transactions virtual currency
first of all, e to its lack of supervision, its circulation and trading forms are mostly similar to the issuance and listing of securities, and there is the behavior of setting up an exchange for trading. Its trading process and trading results are not transparent, and it is difficult to regulate when encountering problems. Moreover, its price formation mechanism is not transparent, and the trading price fluctuates greatly, which is easy to make investors suffer huge losses
secondly, it is not recognized by the central bank and can not be used as currency in China. Once it is subject to policy supervision, it is likely to encounter the risk that no one will take over the offer and the price will plummet, and the property law does not clearly protect the corresponding provisions of digital currency. Therefore, it is very dangerous to speculate on the blockchain, which is equivalent to streaking in the cold winter
finally, although blockchain is not illegal, it can not be ruled out that it is used by a small number of fraudsters and illegal fund raisers as a tool for crime and money laundering
therefore, it is recommended to carefully participate in blockchain investment to avoid irreparable losses.
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
future development and application scenarios of blockchain
1. Digital identity
many people will encounter the dilemma of "proving that my grandmother is an alt" and "my mother is my mother" when they open various certificates. With blockchain, they will never have to worry about it again. It turns out that our birth certificate, real estate certificate, marriage certificate and so on need a central node for everyone to recognize. Once transnational, contracts and certificates may become invalid because of the lack of a global central node
the tamper proof feature of blockchain technology has fundamentally changed this situation. Our birth certificate, real estate certificate and marriage certificate can be notarized on the blockchain and become something trusted by the whole world. Of course, it can also easily prove that "my grandmother is an alt" and "my mother is my mother"
2. Health care
in short, it is to use blockchain to establish a general record repository with time stamp, so as to achieve the purpose of extracting data information from different databases
3. Travel consumption
when we travel, we often use Ctrip, meituan and other apps to find and place orders for hotels and other services, and each platform gets a commission from them. The application of blockchain is to remove middlemen and create a secure and decentralized way for service providers and customers, so as to achieve the purpose of direct connection and transaction
4. More convenient transaction
blockchain can make payment and transaction more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when certain conditions are met, which means that automatic payment can be released when both parties agree to meet their conditions
5. Strictly control the proct quality
if you buy an apple, under the blockchain technology, you can know the whole process from the proction of fruit farmers to the circulation. Among them, there are government regulatory information, professional testing data, quality inspection data of enterprises and so on. The smart supply chain will make the food we eat and the goods we use safer and more reassuring
6. Art of property rights protection
the creator puts his works on the blockchain. Once someone uses his works, he will know immediately. The corresponding royalty will also be automatically paid to the creator. Blockchain technology not only protects right, but also helps creators sell their works to consumers more directly without the assistance of distribution companies.
Yes, the current deception is not surprising. In short, you should be more careful
with the rapid development of mobile communication, online dating has become a widespread form of communication, but there are some sweet traps set by outlaws. How to avoid being cheated in the complicated virtual space, so as to avoid unnecessary property losses
for example, he said that in his uncle's home in Taiwan, he sent a table of food, enlarged the picture, and you can see the logo of the drink, which is obviously a mainland brand, which needs to be seen carefully
marriage is an emotional problem
together, there is no relationship. Marriage and divorce are just a form, and a piece of paper can't guarantee anything.
