How to understand blockchain technology in layman's terms? What are the characteristics of blockchain? How important is blockchain to us? Can blockchain change the world?
After studying blockchain for a week, I have the following current understandings: (1) Virtual currency will become popular, because a certain part of the world urgently needs decentralized operation, and virtual currency is the most effective way to organize it; (2) The essence of blockchain is the improvement of production relations, and it is also one of the most effective ways, which integrates the relationship between practitioners, users and investors from the beginning; (3) Technological progress has always been to improve productivity, and blockchain will completely change production relations; (4) Blockchain is a transparent mathematical presentation, and transparency is the first driving force for the progress of any organization; (5) Blockchain will bring bubble dividends. ——Wang Yuhao A few days ago, as long as the stocks were stained with the "blockchain concept", the stock price continued to rise. However, in the following days, concept stocks in the blockchain sector were hit hard across the board, with more than a dozen stocks falling by more than 5%, which was a big change and raised questions. Is blockchain a "flood beast"? Of course not. Blockchain schematic (picture from the Internet) In our country's 13th Five-Year Plan, for the first time, blockchain, artificial intelligence and other technologies are listed as "major tasks and key projects" during the "13th Five-Year Plan" period, and enterprises are actively encouraged to carry out innovative research on blockchain technology. As a result, the term "blockchain" has gradually attracted wider attention. So what exactly is blockchain? Where is the disruptive potential of blockchain? 1. What is blockchain?1. Evolution of centralized characteristics The concept of blockchain technology is relatively new, but it is a continuation of the human story, how to say: As humans, we are always looking for ways to reduce uncertainty with each other to be able to trade. So far, the first real research in economics is how to use the system as a tool to reduce our uncertainty with each other. Nobel laureate in economics Douglas North, who pioneered the "new institutional economics", believed that institutions (formal rules, such as the constitution; Informal rules, such as bribery) are the lubricant that drives economic development. Institutions have always played an important role in the entire history of mankind. When we were still in the age of gatherer hunting, we could only trade in our own villages, so trading was somewhat informally limited in space. As society gradually becomes more complex, the route of transactions gradually becomes more distant. We have established more formal institutions, such as banks, governments, companies, etc. As the uncertainty and complexity of transactions increase, these formal bodies can help us manage our transactions when individuals are not in control. In the Internet era, we have established the same formal institutions online: such as Amazon and Alibaba. These faster-moving institutions act as intermediaries and facilitate our economic activity. Douglas North prediction (Douglas North died in 2015): Institutions are tools used to reduce uncertainty, allowing us to make connections in society and exchange various valuable things. But today, we are entering a more profound and significant evolution: the way people interact and transact will change. This is the first time that uncertainty has been reduced without formal institutions such as governments and banks, but has been achieved by relying on technology alone. This technology is blockchain. 2. What is "blockchain"? "Blockchain" technology is a distributed database that stores users' asset registration and transaction information through a peer-to-peer network, and in general, it is a public record system that records who owns what and who has traded. Transaction records are securely protected by passwords, and over time, the transaction records are sealed in a database, and then the data blocks are encrypted and securely archived. This creates an immutable and non-lossy record of all transactions under the network, which is backed up on every computer in the network. Blockchain is not an application or a company, how to understand it? Let's use Wikipedia as an analogy. We see every piece of knowledge and entries on Wikipedia (a multilingual web encyclopedia run by the non-profit Wikimedia Foundation) that is constantly changing and updating. We can also track these changes in real time on Wikipedia, and of course, we can create our own wikis. Because its core is: the infrastructure of knowledge data. Wikipedia is an open platform that stores text and images, as well as data that is updated over time. "Blockchain" can be regarded as an open infrastructure architecture that stores various asset "histories", including asset managers, owners, and locations. Because blockchain is a public system of record that stores all transactions on the network, and it can be replicated to every computer in the network, it is highly secure and virtually impossible to tamper with. We can describe what blockchain is in a more complete and popular way. The "blocks" in the blockchain are data packets, which we can imagine as encapsulated packages, which are full of notebooks that record data, and these data can be imagined as accounting ledgers. "Blockchain" is a chain formed by blocks connected end to end. The following diagram can be seen as two blocks of the blockchain.
