Zhihu of blockchain
Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:
1; Hash chain & quot There are several nodes participating in the system operation (distributed)
3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm
since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications
ant finance applies blockchain technology to public welfare projects, making public welfare more open and transparent, avoiding the recurrence of Guo Meimei event; Puyin is a high-quality Tibetan tea asset, which is stored, identified, evaluated and authorized by three parties. It is a standard digital currency issued by encryption and digitization. Puyin strictly implements the concept of "white paper on standard digital currency" in accordance with its operation guidelines, and establishes standards for asset digitization; China Post and IBM have jointly developed a set of asset custody system based on blockchain technology.
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
First of all, don't think too much about blockchain. It's a database storage system that is distributed all over the world and can work together. Different from the traditional database operation, where the read and write permissions are controlled by a company or a centralized hand (the centralized feature), blockchain believes that anyone who has the ability to set up a server node can participate in it. Gold diggers from all over the world deploy their own nodes locally and connect to the blockchain network to become a node in the distributed database storage system; Once joined, the node enjoys the same rights and obligations as all other nodes (decentralized, distributed features). At the same time, for those who carry out services on the blockchain, they can read and write to any node in the system. Finally, all nodes in the world will synchronize one after another according to some mechanism, so that the data of all nodes in the blockchain network is completely consistent
blockchain itself is a technology, so it can't be a fraud. Just like the normalized "P2P" finance in recent years, how many fraudsters are wearing the concept of P2P to illegally absorb public funds and cheat people's hard-earned money? But is "P2P" guilty? It's just an indivial to indivial mode of Internet finance. It not only creates profits, but also helps thousands of people get rid of poverty, so as to achieve a win-win situation between the poor and the poor. The problems of currency exchange digital currency trading platform
can not hinder the development of blockchain, such as simple payment verification, side chain, lightning network protocol and other technologies proposed and in-depth research, which has been the problem solved by blockchain
however, as Ethereum and hyperledger fabric have the best support for go language, go language must be learned
next, I'll give you the answer to another question, hoping to help you
Background: I started to study blockchain technology in 2015, so I have a certain understanding of blockchain
statement: it is estimated that everyone who sees this question wants to get started with blockchain, so this answer is mainly an introction at the entry level. It's just an introction at the entry level, which is not suitable for blockchain practitioners to improve their learning.
