What is the difference between blockchain and mining machinery
bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:
first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed
In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
IPFs was just started in 2018, and it started to be popular in 2019 recently. Because the main network has not been officially launched, it has not been possible to start formal mining. However, many people have started to reserve hard disk mining machines now, because it is cheaper now. For example, the interstellar Aoyun is a more popular one. It is estimated that it will have to go up a lot at that time
IPFs miner is more environmentally friendly than bitcoin miner. It uses hard disk to mine, so the noise and power consumption will be greatly reced. Moreover, hard disk is not easy to depreciate, so the cost of participation will be relatively low.
mining is a proct based on blockchain technology. Mining refers to the virtual currency launched by various companies, which is also called token. If the name is different, the miner is called miner
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 societyblockchain 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/btcto put it simply, blockchain is a new application mode integrating various computer technologies. Just treat it as a new technology. The network constructed by blockchain technology has the characteristics of "decentralization", "information tampering", "openness", "anonymity" and "security and reliability". These technologies can be applied in many fields, in short, it is very powerful ~
miner, a simple understanding is a more advanced computer, miner is to contribute to the blockchain network, you can regard miner as the guardian of blockchain
with mining machines, the blockchain network can operate normally. These mining machines are constantly doing calculations to provide computing power for the blockchain network. When the mining machine makes the correct calculation, the whole blockchain network will reward the mining machine with the corresponding digital currency. This process is called mining
if you also want to make a "contribution" to the blockchain, you need to download the mining system to start. Oh, let's have a look.
