What is blockchain?

What is blockchain?First of all, we’d like to emphasize that blockchain technology is helpful. And the reason why people get nervous when talk about blockchain,is that some people tried to use blockchain technology ,to commit fraud or other illegal activities. And this led to the equating the blockchain with crime.
It is known that blockchain industry consists of cryptocurrency, chains and crypto mining 3 parts. When talking about cryptocurrency, currency speculation is the first thing comes up.Similar to stock speculation,it is a high-risk and high-yield investment.I won’t go into details here.However, transactions of cryptocurrency are very easy to be used by criminals,to engage in money laundering or other illegal activities. Therefore, cryptocurrency transactions are illegal in many countries.If you are interested in investing, please check the laws and policies of your own country.
People preferred to modify chains,to use the applications of blockchain technology to reform or transform their business.The majority of them are enterprises.
People mining cryptocurrency are called miners or mining workers.They buy equipment to “produce” cryptocurrency .Because the cryptocurrency policies become stricter and stricter,many people turn their attention to mining.Compared with currency speculation,mining has lower risks and income is more stable.However, mining is too power-hungry to be environmentally friendly.Many countries put it in the phased-out list or banned crypto mining.
Because of this, many crypto mining equipment producing companies started to pay attention to environmentally friendly mining.For example, Bitmain explores the use of green energy,and JASMINER produced low-power consumption products.They provided their solutions to the contradiction between computing power and energy.
The scope of the blockchain is wide,and MinerV would like to remind people who are interested that we often hear that,many people “get rich overnight” through the blockchain.However, the laws and policies of each country are different.If you want to invest,you need to understand the laws and policies first,and don’t challenge the laws or policies.

A blockchain is a distributed database that is shared among the nodes of computer network. As a database a blockchain stores information electronically in digital format.
