Popular science articles on blockchain

1.

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 high

5. 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

Thank you. Let me give you a serious answer

in fact, the circle effect of blockchain is very obvious, so most people are impetuous, some of them are attentive, and there is very little popular science. I recommend a few here

if you want to watch the video, you can recommend Babbitt's "meow understands blockchain", which is very deep. This is the sentiment of the people who want to watch it. I won't say more about other videos. I think the video of fire coin can also see the words of trust, but it's relatively shallow. I watch it as a kindergarten child

if you are not limited to videos, I think there are several popular science articles to recommend: Jiang Zhuoer's popular science in Zhihu, Gu Qianfeng, lightning, and pan Zhibiao are all great gods. Each category is different. You have to think about it yourself if you want to enter the circle

the things in PS blockchain field are sent here, and there are few people watching them

4. It's fire chain finance. News updates are fast and the quality of articles is high.

1. Application of blockchain technology in the banking instry the biggest feature of blockchain technology is decentralization, which will rece a lot of costs for the banking instry. The development of digital currency will make it possible for banks to realize real-time digital transactions. For example, in bill transaction, bank bill transaction always relies on the third party to realize the transfer of valuable documents. Even in electronic bill transaction,

also needs to be authenticated through the information of central bank ECDs system. The blockchain technology can realize the point-to-point value transmission, which no longer needs centralized system control. This not only speeds up the bill transmission speed, but also reces the mistakes caused by human factors. The rection of process will naturally rece the demand of the bank for personnel and save the labor cost of the bank

2, the application of blockchain technology in the insurance instry

blockchain technology also has incomparable advantages in the insurance instry. From the perspective of data management, the application of blockchain technology can effectively improve the risk management and control ability of insurance companies, including the risk supervision of insurance companies and the risk management of policyholders

the application of blockchain technology in the insurance instry can strengthen the internal risk supervision of insurance companies. Blockchain technology can record the daily operation process of insurance company on the node, realize the in-process control of the company's capital flow, investment situation, compensation amount and other business, and improve the company's risk management and control ability

3. Application of blockchain technology in the securities instry

4, blockchain technology and financial infrastructure

blockchain technology is a decentralized mechanism for value exchange, which will lead to earth shaking changes in the existing financial infrastructure characterized by centralization

5. Application of blockchain technology in supply chain, It has become an effective guarantee for enterprise bank's loan credit, financing credit and transaction credit

6. Blockchain is characterized by decentralization, distrust, collective maintenance and reliable database

7. The real person of Nakamoto is a mystery so far. Of course, many people have claimed that they are Nakamoto, and some people have been speculated that they are Nakamoto, such as Tesla's CEO musk, but in the end, they can't get a strong proof. But I think a mysterious cryptography organization might know. This group is the famous cryptopunk, and it is in this group that Nakamoto first released the white paper of bitcoin. Cryptopunk is a group of activists and dreamers who advocate the widespread use of encryption technology to promote social development. Its members are like thunder, such as Assange, the founder of WikiLeaks, Bram Cohen, the inventor of BT download, Sean Parker, one of the founders of Facebook, and so on. Before Nakamoto, cryptopunks had made similar attempts to bitcoin, but they failed, but they left valuable experience and reference for the birth of bitcoin.
