Disadvantages of pow mining

1. There are related POW double digging, but the so-called POW intelligent double digging is a false proposition. For example, some mining machines or mines proce platform currency, and then pay for the currency of digging, which is double digging. It doesn't depend on the amount of digging, but on the overall rate of return

2. There are many consensus mechanisms in the blockchain. The advantage of the pow consensus mechanism behind bitcoin, the most influential one, is that it is secure and can not be tampered with. The disadvantage is that it is too slow to process only seven transactions a second

3. Let me tell you this: POW has almost all the advantages and POCS have none of the disadvantages. Bitcoin's pow consensus mechanism has obvious shortcomings: energy waste, noise, mining centralization. The cost of bitcoin mining is getting higher and higher, and the computing power is concentrated in several large mines, so it is difficult for ordinary users to participate; HDFS adopts POC mechanism for hard disk mining, so that everyone can mine.

4. I have heard a friend who has been mining for three or four years mention that the team members of Bateman information technology company are specialized in the research, development, manufacturing and sales of virtual currency mining equipment. It is said that they initially made traditional POW mining machines, and then graally turned to hard disk mining machines with the development of the instry. They have rich technology and experience, and the procts launched today are also very good.

5. Bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system. It can be circulated all over the world with a fixed total amount and no issuing body< At present, there is no legal electronic currency in China. QQ currency is a kind of game currency with fixed value, which is released by Tencent. Alipay's three party payment system is a means of payment. They all have the subject of operation. Legal tender is issued by the central bank and endorsed by the state as credit

Shanzhai coin is to learn from bitcoin and innovate and expand on the basis of bitcoin. The user community cannot be compared with bitcoin. The consensus of many people in the community is that some well-designed counterfeit coins will become a supplement to bitcoin, and bitcoin will become a supplement to fiat money, with one more choice.

7. First of all, you can register a company in Hong Kong of any nationality. Secondly, most of them are not registered in Hong Kong. For example, the famous Biyuan chain, quantum chain, Ethereum and fire coin network are not registered in Hong Kong, most of them are in Singapore. It's also registered in Switzerland
it's very easy to register a Hong Kong company. You only need to provide your ID card and company name. The registration time is 10 to 15 working days. It's very fast.

8. Science and technology change life, but also to promote the driving force of economic development. In recent years, the wave of mobile Internet and big data technology is higher than one wave, rapidly leading the development trend of the new era. In 2017, when new things and new technologies continue to emerge, the emergence of blockchain undoubtedly set off a new revolution in digital economy. Chongqing jinwowo network technology group, in line with the current national policy of the development of big data instry, deeply explores the research and development of blockchain technology, explores the application of blockchain technology, and is committed to developing into a well-known brand in the field of blockchain in China, leading the new ideas of blockchain development.
