The computing power fluctuates greatly
computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow
computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value
therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world
unit of force
1 KH / S = 1000 hashes per second
1 MH / S = 1000000 hashes per second
1 GH / S = 1000000000 hashes per second
1 th / S = 100000000000 hashes per second
1 pH / S = 100000000000 hashes per second
1 eh / S = 100000000000 hashes per second
in the end, there is a lower electricity price. The ultimate purpose of the trusteeship enterprise to carry out the mineral machinery trusteeship business is to make profits. If the trusteeship enterprise can not get lower than the normal electricity price on the market, it is difficult for the trusteeship enterprise to make profits. Of course, the electricity price given to the investors will also be lower than the normal electricity price on the market. Another important advantage is that some trusteeship enterprises are able to cash the virtual currency g up by investors' mining machines directly, which also relieves some investors from the worry that they can't cash the virtual currency
at first, I thought hosting was expensive, but later I found that it was still so convenient. I always bought mining machines. The mining machine sales platform (honeycomb) would transport them to the mine for you, and there was a special person to manage and maintain them for you. I just looked at how much money I earned every day, which was much easier. New people even suggested hosting.
For example, when many enterprises choose servers, they will consider the difference between blockchain servers and traditional servers? The following is a brief analysis
to be exact, the blockchain is a technical model, and the server is a type of hardware resource. There is no contrast between the two. However, if we insist on the difference, we can also see the difference and connection between the two
to say the difference between the two,
the biggest feature of blockchain is decentralization, such as bitcoin, the most typical application of blockchain. Bitcoin is independent of any third party's decentralized currency. There is no centralized issuer. It is generated by the calculation of network nodes. Anyone can run bitcoin client software on the computer to participate in the proction of bitcoin. No matter where they are, anyone can dig, buy and sell bitcoin
all nodes of the blockchain are distributed in different places, and each node is maintained and managed by itself. It does not need centralized construction, but also needs special management and maintenance, which can make full use of idle resources. Due to the distributed characteristics, the system is difficult to destroy, such as bitcoin. Even the most powerful people or organizations in the world can't destroy the bitcoin system based on blockchain
traditional server is centralization service
traditional centralization server, such as WeChat, Alipay and so on, are all responsible for providing services to all clients by the server behind the company, and the client acquires services from the server. If their servers are attacked and paralyzed, then your WeChat and Alipay will not be able to use them. For example, on May 28, 2015, Ctrip was attacked by unknown server, and its web version and mobile app could not be used normally
does the blockchain still need servers
to be specific, blockchain is also divided into public chain, private chain and alliance chain. The essential difference between the three is that they have different degrees of decentralization
that is, the public chain is completely decentralized. The above mentioned bitcoin belongs to the public chain. The private chain and alliance chain are not completely decentralized, and there is still a shadow of centralization
as mentioned above, blockchain is a technical model, and server is a type of hardware resource. The two will inevitably have a combination of applications
for example, the combination of storage type server and blockchain can use cryptography to ensure the security of data transmission and access, so as to make the storage server data more secure

At the end of 2017, digital currency experienced explosive growth and Waterloo like decline in 2018, and now it tends to be stable. During this period, a large number of investors poured into the currency circle, and all kinds of digital currencies need to be bought and sold through exchanges or digital currency wallets. However, in 2018, there were frequent incidents of exchange digital currency theft, so more and more traders chose to store digital assets in digital currency wallets, Sort out the five most well-known digital currency wallets and let's get to know them
Bitpai (score: 8.5)
bitpai is a comprehensive blockchain asset service proct based on HD wallet. Its main functions include: sending and receiving, buying and selling, accelerating transaction, etc. The user controls the private key, and the coin after the transaction is completed is directly kept by the user. At present, the currencies it supports mainly include BTC, BTC, ETH, some erc2.0 tokens, qtum, HSR, dash, safe, LTC, LCH, Zec, etc and Doge
advantages: the balance of the current digital currency can be displayed at the top of the front page of the wallet, and the upper left corner can be switched to other digital currencies, and the currency balance can also be switched from quantity to legal currency value. There are many functions in the middle, such as issuing currency, receiving currency, one click trading, etc. the broadcast of each transfer transaction is displayed below, and the completed transaction can also be queried in the transaction record. After leaving the bitpai app interface for a period of time, you need to unlock it when you re-enter, which improves the security of the wallet
deficiency: Only Mainstream currencies are supported, other small currencies are not supported, and the number of currencies is 10 +. The page setting is not user-friendly, and various parameters make it difficult for users to use. In addition, the security is worrying: Recently, there is a problem with bitpai IOS version, and the application can't be opened, and the official said: if you unload it carelessly, the assets in your wallet may not be recovered! It's still in Apple communication
