Does blockchain have anything to do with yipao
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
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
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.
Blockchain technology has been popular since its birth. For the general public, it seems to be very close to us, but we don't know what it (blockchain) is; In fact, the blockchain instry, which is still in the early stage of development, is in chaos both from the technical level and from the content level
What is blockchainblockchain is a technical solution to maintain a reliable database collectively through centralization and distrust. In short, blockchain technology is like a nationwide accounting method. There is a database behind all the systems. You can think of the database as a big ledger. When the data changes, everyone in the system can make bookkeeping, and the fastest and best bookkeeping person will be written into the account book and sent to other people to complete the update of the account book. This way, we call it blockchain technology
, for example, in the payment behavior, there should be third parties involved in any transfer before, for example, the third party organizations such as banks or Alipay, and the block chain technology can effectively solve the intermediary credit problem, so that two people who are not acquainted with each other can complete the transfer directly without the third party. p>
2. What are the advantages of such a nationwide bookkeeping blockchain
knowing what a blockchain is, it is not difficult for us to find that although the efficiency of blockchain is sacrificed, the security is greatly guaranteed. First, the system can hardly be destroyed; second, the accounting process is open and transparent, and cheating is impossible; Third, the cost is greatly reced, and the efficiency is relatively higher
Is blockchain software? What program is it written inperhaps through the above introction, some people will ask, is blockchain a specific software? Actually, it's not. Blockchain is like a database. It's a design idea of a specific technology. It can be implemented in most languages, and in many ways
having said so much, you should know what blockchain is. In fact, blockchain has little to do with the ordinary people born in the 90s. We just need to enjoy the convenient services brought by the Internet or cloud services, unless you want to take blockchain as a business. At present, blockchain technology is still developing rapidly, and its design idea is relatively simple, Maybe it will become more complicated in the future
Blockchain technology is a new technology derived from the development of bitcoin economy, blockchain technology can effectively serve the bitcoin economy , they are interrelated. Bitcoin is a kind of virtual currency, which only circulates in a specific network economic environment, blockchain technology can not only be applied to the economy, but also can be used in all walks of life , which is their difference
Blockchain technologybecause blockchain technology is still a new proct at present, it has no accurate or definite definition and concept. In short, blockchain technology is a mode of data encryption management, which can protect data to a great extent. Blockchain technology is characterized by decentralization, openness, independence, security and anonymity. Its characteristics well adapt to the requirements of information protection and information disclosure in all walks of life. On the one hand, it ensures the security of data and avoids the interference of subjective emotions and system failures. On the other hand, data indivials can decide whether to hide their detailed information in the group to the greatest extent, so as to achieve the purpose of privacy protection
At the same time, there is no doubt that the blockchain technology is still in the state of preliminary development. The social understanding of it is not deep enough, and scholars are still in the stage of continuous exploration. Through the correct use, blockchain technology will bring many positive effects to the societybitcoin is regarded as the first generation application of blockchain technology and the most thorough application of its code testing. However, without bitcoin, there might not be so many people who knew about blockchain now. It can be said that bitcoin has greatly improved the "exposure" of blockchain technology
later, people graally found that the application value of blockchain is far more than bitcoin, but can be applied to many instries to solve the pain points of many instries; The idea of blockchain can also provide a lot of reference for the financial field, which is the real reason for the outbreak of blockchain.
blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcBlockchain is a technology used by bitcoin and a database technology
bitcoin is an application of blockchain and a digital currency
blockchain technology was born with the birth of bitcoin, but blockchain technology is not limited to bitcoin, or even digital currency, but has a very wide range of applications
In 2008, Nakamoto published a paper on bitcoin, commonly known as the white paper on bitcoin. Among them, the concept of blockchain was put forward in Nakamoto's white paper. A blockchain is a series of data blocks (called "blocks") generated by using cryptographic correlation. New data blocks can always be linked to the last block, that is, the end of the whole blockchain. Bitcoin's peer-to-peer network stores all transaction history in a "blockchain."since the advent of bitcoin, more and more digital cryptocurrencies using blockchain technology have been introced, and up to now there are nearly 3000 kinds.

but in addition to the field of cryptocurrency, blockchain technology has been widely used in finance, Internet of things, logistics, insurance, digital right and other fields
