1. POW: full name of proof of work
pos: proof of stake
both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency
the difference is:
1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power
POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the
mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbers
extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
2. Qwertycoin, which has been popular recently, was built by the geek team in Germany for 18 months. It is a secure anonymous coin that focuses on privacy and is used for global
secure payment. Qwc has no pre excavation and ICO, and adopts cryptonight algorithm (supporting mainstream mining machine X3 and A8 +) POW mining.
3. 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
4. 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.
5. 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.
6. 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. Biter trading platform official system event: biter announced on its official Sina Weibo that their NXT central account was hacked and hackers stole 50 million NXT coins
8. 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.
9. 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.
10. Let me help you analyze Citex's main mineral currency. Citex's bull currency is like a tide, which is the victory of the pow mechanism. On the one hand, the issuance mechanism of mineral coins is more fair, and each coin needs to consume a certain mining cost. Mineral coin is different from ICO token. The cost of issuing ICO token is low, and the marginal cost is close to zero. If there is no cost, it is difficult to form price support. ICO token is often reced to a tool for project side and capital side to harvest retail investors. On the one hand, most of the coins are decentralized
