Blockchain bitcoin LAN Shao microblog
bitcoin is a virtual currency. blockchain is the node to calculate virtual currency transactions. In short, blockchain technology ensures the normal operation of bitcoin system. How to describe the principle of blockchain. That's what the ledger means. I don't know if it's easy to use. It's said that it's quite encouraging. After all, it takes ten minutes to calculate the database account book in this area
but the bitcoin market is unstable recently. Let's have a look. Maybe I'll see you on the roof
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/btcrelationship between blockchain and bitcoin: bitcoin used to be one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. It can be said that bitcoin is a "killer application" of blockchain idea. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin.
bitcoin:
is an electronic currency proced by open-source P2P software. Digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin."
bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. Since bitcoin was born with an algorithm, it was stipulated from the beginning that all bitcoins in the world would not exceed 21 million bitcoins. Because bitcoin is not regulated by the government, it is not subject to inflation constraints and external control
people use the computing power of CPU and CpG to "mine" to unlock the new bitcoin. To put it figuratively: bitcoin is equivalent to a gold mine created by people using computers. The setting of this gold mine is limited. The upper limit is 21 million bitcoin. People dig out bitcoin one by one just like miners using the principle of CPU computing
the principle of bitcoin, the distributed characteristics of P2P and the design without central management mechanism ensure that no institution can control the value of bitcoin or create inflation. This decentralization makes it a more secure and value preserving "virtual currency"
But in fact, netizens, as well as traders and investors of bitcoin, do not see one of the biggest drawbacks of bitcoin: bitcoin is not uniqueWhat do you mean? We think that bitcoin is the only one with a cap of 21 million, which seems to have the function of preserving value. But the principle of bitcoin algorithm is not only applicable to "bitcoin", a kind of currency from Japan. Every computer engineer can develop the corresponding algorithm, make a man-made gold mine, and control its upper limit. In this way, every country, every region and every person can develop countless algorithms. Then the market will be full of virtual currencies such as "bitcoin a", "bitcoin B", "bitcoin C", "bitcoin D", and so on. By that time, who are you going to invest in? You can create your own currency
this hidden danger is not a dream. In fact, it has already started. You can log on bitcoin's official website in China. You will find that in addition to bitcoin, there is now another kind of thing called "Yuanbao coin". This is an algorithm similar to bitcoin developed by a Chinese development team. It also has the same upper limit. The same people can't control it and dig Yuanbao coin out through "mining"
if they can do this, I believe many computer workers can also write their own "Yuan Bao coin", "gold and silver coin", "China bitcoin" and "Shanghai bitcoin". Bitcoin, as the first code to appear, has no credit support from the Central Bank of any country. It has value only because of the scarcity of 21 million. In fact, this scarcity does not exist, because everyone can develop the virtual currency code, and then people from all over the world can mine it. So what's the price of bitcoin? There are limited kinds of metals on earth, so each metal has different value according to its quantity and scarcity. But the bitcoin like code in the network world is infinite. As long as people are willing, they can create unlimited kinds of bitcoin code. Tell me, is bitcoin still valuable
blockchain Technology:
the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database
the essence of blockchain is to achieve the goal of decentralization and disintermediation through a new generation of data technology, so as to transmit value more transparently and efficiently. This kind of point-to-point verification will proce a new network "basic protocol" which is different from TCP / IP in the Internet era
blockchain shows us a world in which all assets will be digitized. In a valuable Internet, the transfer of assets will be as fast, convenient and cheap as the transmission of information today
the significance of blockchain is not the wealth of digital currency, but the value transmission of its technology itself. Therefore, Ma Yun has repeatedly separated blockchain from digital currency, and stressed that the extent to which blockchain technology will change the world is beyond people's imagination
difference:
blockchain is a technology, based on blockchain technology, there can be many applications
bitcoin: is one of the most popular and well-known applications

It should be noted that the fire of bitcoin has made many counterfeit coins spring up like mushrooms. Without technical knowledge, the stability of counterfeit coins can not be recognized, so we need to be extra careful; More importantly, many pyramid schemes and scams are disguised as "virtual currency". We must be careful to identify them and avoid being cheated
1. Blockchain is the core technology of bitcoin's original creation. Before bitcoin was invented, there was no blockchain in the world
2. After the invention of bitcoin, many people refer to the blockchain implementation in bitcoin and use similar technologies to realize various applications, which are collectively referred to as blockchain technology. Including the birth of all kinds of high-quality coins on the coin easy platform, it is the same reason
now the building owner will see if his questions are immediately clear.

in short, blockchain is composed of numerous small databases. These small databases, like small ledgers, record everyone's information in chronological order. When people's behaviors are related, the information recorded in each person's small ledger can be mutually verified, so that the information in the whole blockchain can not be falsified or tampered with. To sum up, blockchain is a network database technology with the characteristics of decentralization, security and anonymity by "witnessing the whole network" and "truthfully recording" all transaction information. Now the blockchain technology has just begun to develop, but the bitcoin transaction is very mature. If you are interested in learning more about bitcoin, you can go to the okex platform.
