Starting point permanent miner
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law
extended information:
{rrrrrrr}
transaction mode
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
mining machine: it is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server. In the early days of bitcoin, ordinary personal computers could also find bitcoin
Mining: this mining is not mining in the traditional sense. It refers to indivials or organizations using mining machines to obtain bitcoin<
Mining pool: after all, the ability of indivial mining is limited, so some people come up with the idea that everyone can work together to mine, which can not only improve the mining speed, but also save the mining time. The bitcoin g is allocated according to their respective contribution proportion. Generally speaking, it is a mining team with many people, great calculation power and great strength
computing power: 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"
the above is the basic knowledge of digital currency. Next, we will answer the questions about GEC currency. GEC uses cloud computing, so players don't have to buy mining machines to mine
1. How to fill in paypal and BTC wallets when registering
A: Please fill in none of the two, or 1. At the same time, please open the registration link in the browser
2, how to obtain the mining machine
A: users can get a mining machine free of charge if they register and pass the real name authentication. 2.1 GEC coins are proced in 2 months
3, how can we get GEC
A: after the running time of the mining machine is over, log in to my mining machine for settlement, and you can get GEC currency
4. How can GEC be realized through trading
A: in the personal trading center, you can sell GEC, which is matched by the platform. Due to the constant output, the price will continue to rise in the future. If you want to sell GEC, please think twice.
Alibaba cloud declares that it will never provide "mining platform" and virtual currency on January 17, according to recent media reports, Alibaba has launched the virtual currency mining platform "P2P node", pointing out that Alibaba is recruiting mining machines. In this regard, Alibaba cloud refuted the rumor late at night on January 16, saying that the business had nothing to do with "mining platform" and "virtual currency" . Alibaba cloud stressed that it will never issue any virtual currency such as bitcoin or provide any so-called "mining platform". For false reports, legal responsibility will be investigated in accordance with the law {rrrrrrr}
we have noticed that recently there are media reports that Alibaba launched P2P nodes of mining platform. After verification, the service is actually a CDN (content distribution network) service based on P2P technology of Alibaba cloud, and has nothing to do with "mining platform" and "virtual currency"
P2P (peer-to-peer network) node is a common user sharing bandwidth acceleration service in CDN instry. Users can share the idle uplink network bandwidth through personal computers, routers and other devices, and become a micro CDN distribution service node, which enables other customers to get a nearby accelerated experience when downloading, live broadcasting, games and other scenes
for the resources that users are authorized to share, Alibaba cloud CDN gives rewards in the form of points, which can be used to replace gifts in points shopping malls, without monetary function and speculation value
we once again declare that Alibaba cloud will never issue any virtual currency such as bitcoin, nor will it provide any so-called "mining platform"
we will investigate the legal responsibility for the false reports

from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. The go language itself pays more attention to distributed systems, and concurrency processing is relatively good, such as advertising and search, which are high concurrency servers
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.
In order to promote the starting point app, another reason is that the web version has illegal comments from users who have not been authenticated by their real names in the past. Often, such comments have exclusive websites, which can be easily visited by regulators or reported by readers. In order to prevent this adverse risk, they simply move to the mobile end and deprive those users who have not been authenticated by their real names of their right to speak, At the same time, increasing proceral resistance makes supervision more difficult
but to be honest, interests are more important than risks, so the mobile end can easily obtain readers' privacy data. In the future, most web pages will turn to the mobile end, because only the mobile end can mine user data with app, let the company own data gold mine, and increase profit channels. This is the driving factor to close the web comment area. After all, the data business department has been established, You can't cheat people with your salary and project money
updated on June 11: on May 28, the online information office issued the "data security management measures (Draft)", which stipulates that network operators shall not force or mislead personal information subjects to agree to collect personal information by default authorization, function binding and other forms
many companies are going to fail, and the application of big data makes user data a gold mine. Originally, some app operators were in the process of transformation, collecting user information through various means without the consent of users, and then seeking economic benefits. If the starting point app has to collect your address book, geographical location, SMS and telephone authority, it is recommended to report the complaint to the office of information technology in time
updated on July 17: e to the problem of collecting and using personal information, the working group of APP special governance issued the notice on urging 40 app operators with the problem of collecting and using personal information to rectify as soon as possible, in which starting point reading, soul, scallop words and lakara were all named
