Why is blockchain abandoned

1. This is not a rigid rule. It has nothing to do with blockchain. There is a relationship between the algorithm of this currency. The confirmation method of each currency is different, so this is not a rigid rule
the confirmation times of bitcoin are different from that of Ruitai coin, Laite coin and doggy coin.

2. I transfer bitcoin to you. Do I still have bitcoin in my hand
the fourth feature of blockchain assets is that they cannot be copied. The transmission of information on the Internet is . I sent a very interesting picture to fire coin Niuniu. The network copied the picture in my hand to Niuniu. It wasn't really taken away from me. I still have this picture in my mobile phone
right on the Internet has always been a big problem. Words, pictures and images are easy to , which brings great trouble to their right owners
the reason why blockchain assets can become assets is that they cannot be copied. It can be delivered through encryption rather than ing. When I send a block chain asset worth 1000 yuan to Niuniu, the 1000 yuan asset will be transferred from my account to Niuniu's account, and I no longer own the 1000 yuan asset. Non replicability is an important factor to ensure that it becomes an asset.

3. Because each block contains its own hash value and the hash value of the previous block, changing a hash value will invalidate the rest of the blockchain
if you have problems with blockchain, you are welcome to chat in private~~~~~

Blockchain is not deceiving, but deceiving people under the guise of blockchain. In fact, blockchain scam is to make use of people's ignorance of the technology, and then fraudsters rely on various and fancy means to set up scams. Many people only look at the surface when making investments, and finally fall into the trap of high profits

in the current society, more and more people are willing to take this risk to make investment in order to get rich returns, but not all of them can make profits. After all, where there are interests, there are many people waiting, and they will set traps for people to take the t

precautions

blockchain is a technology. In short, this technology is a new way of data management based on cryptography. Blockchain technology has broad application prospects because it has the advantages of decentralization, non tampering, tracing and so on. And issuing currency is a kind of behavior derived from blockchain technology. At present, the vast majority of blockchain applications which mainly focus on currency issuance and speculation are suspected of illegal fund-raising

blockchain technology is still in early development, and it is difficult to apply it. If you only rely on a white paper to claim that there is an application, it is a deception in itself

Blockchain is on fire! It's so hot that I have no friends! In recent days, it has been swished by various popular science jokes of blockchain, just like crowdfunding, equity and original stocks in the past two years. If you go out and chat with others, you will be embarrassed to chat with others if you don't talk about blockchain. Textbook like explanation: an intelligent peer-to-peer network that uses distributed database to identify, disseminate and record information. It is a distributed database system with different nodes and an open ledger

the concept of "after the rules are settled, everyone will register spontaneously" in wechat organization corresponds to the concept of "decentralization, no single user can control it" in the blockchain. "Registration in wechat group" in wechat group corresponds to the concept of "peer-to-peer network" in blockchain. "As long as the network is connected, we can know the latest progress" in wechat organization Bureau, corresponding to the concept in blockchain, namely "game mechanism"

6. It's not that there's no fire, it's that ordinary people don't know much about blockchain technology, and blockchain technology is not without fire. Take chestnut as an example, the first project launched by blockchain start-up company Abbott Financial Technology Co., Ltd. is concentric mutual aid. The goal is to continuously promote the application and development of blockchain technology in China from the perspective of network mutual aid. As the first real blockchain landing application in China, concentric mutual aid combines open source code with practical application, and realizes the deep matching between blockchain technology and network mutual aid
compared with developed countries, China's insurance instry has developed for a short time, and the coverage rate of indemnificatory business, especially insurance types such as accident, serious illness, fixed life insurance and family property, is low, which makes it difficult for low indemnificatory and special groups to seek risk protection procts. In this reality, as a supplement of social security and commercial insurance, network mutual assistance can provide a group heating option for the low security group, which has a positive insurance inclusive effect. Yang Yong said, "blockchain technology can be applied to all aspects of social innovation. Our vision is to provide low-cost and adequate personal and property protection for the people who need protection most in China, so that insurance can benefit the public. After that, we are willing to open up this technical solution, so that more fields can benefit from the popularization of blockchain technology. "

7. The analysis of Chongqing jinwowo network is as follows:
based on the characteristics of decentralization, even if the blockchain is seriously attacked by hackers, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
this is a distributed data storage based on blockchain, because there is no centralized management center, so that even if a node in the blockchain system is attacked or tampered, the healthy operation of the whole network will not be affected
because the rights and obligations of all nodes are equal, and the activities will be supervised by the whole network. At the same time, each of these nodes has the ability to vote with computing power, which ensures that the result recognized is the result recognized by more than half of the nodes.

8. Blockchain belongs to the underlying technology of the Internet, and the most successful application is bitcoin
in turn, the success of bitcoin has driven the development of blockchain
the main features are "decentralized", "traceable" and "tamper proof". The transaction nodes of a and B can be seen throughout the network, and the records are not modifiable
