Synonyms of mining machinery
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
because the probability of a single miner digging a block is very small, after all, it takes a lot of computing power to dig a block in 10 minutes. Even if there is such a large amount of computing power and the ability to dig, there are many competitors. So it becomes a game of 0 and 1. And the emergence of the mine pool is to break the 0 and 1 play. The computing power of a mine pool is a collection of many miners' computing power, which is far more likely than fighting alone. Every time you dig a block in the mine, you will be rewarded to the indivial according to the percentage of the calculation power of your mining machine in the total calculation power of the mine, and there will be no unfair situation.
when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved
the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin
ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times
GPU miner refers to the miner that uses GPU graphics card as the core of computing power. Cryptocurrencies such as Ethereum, bitcoin and diamond use graphics algorithms, so the speed of computing with graphics card will be the highest. Compared with ASIC miner, GPU miner is more well-known, because it is a computer with enhanced graphics card configurationthe purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption
in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present

No "Zhongtian Shengxiang" and "gaiwang" and "Yijian brother" are different names of the same subject, and they are all pyramid schemes. There is no national supervision and filing, which is deceptive. It obtains high returns by developing offline. Publicity routines are similar, and business models are similar. After o2o, Internet +, sharing economy, blockchain technology these hot words the legal representative of Zhongtian Shengxiang is Kou Nannan. At the beginning of 2019, the company, which has been established for less than a year, promises to realize huge wealth appreciation in the short term relying on the Internet revolution. It's not a legal company. It's specialized in pyramid selling extended data: Zhongtian Shengxiang's bchc is just a fraud pyramid selling prop under the guise of blockchain. Zhongtian Shengxiang, formerly known as one key brother of the Internet, has committed crimes in six regions, and there are dozens of judgments related to the Internet the "covered net" funds and original stocks promoted are not supervised or recorded by relevant state departments, and there is no evidence to prove that the so-called funds or original stocks are recognized and protected by relevant laws and regulations, which is deceptive for the case of Kou Nannan, a legal person of Zhongtian Shengxiang, who was involved in the pyramid selling through Internet, see the criminal judgment (2017) Lu 13 Xing Zhong No. 560. This judgment also defines the stock fund ring the period of Internet coverage as illegal securities and fraud props after the case of one key Godot, it was renamed Zhongtian Shengxiang, which was exposed by the southern weekend and other big media. It changed its face again and used a virtual currency called bchc to defraud pyramid selling

my view of bitcoin is that it is a very risky investment. Some scholars have pointed out that bitcoin is halved every four years, which was originally designed by Nakamoto. Moreover, Nakamoto has also designed the total amount of bitcoin, which has prevented inflation to a certain extent. However, it is precisely because the bitcoin reward of blockchain is halved every four years, so in 2016, after the price of bitcoin plummeted, it quickly recovered and reached its peak. Therefore, it can be said that this design of Nakamoto Tsung actually ensured that the value of bitcoin would not decline too much to a certain extent. Bitcoin has entered a crazy state since 2017. The price of a bitcoin once rose to more than US $20000, which caused many speculators to rush in. Bitcoin, based on blockchain technology, entered an oscillation period of decline at the end of 17. It once dropped to about US $5000 and rose to more than US $10000 after the Spring Festival. It can be seen that every time the price of bitcoin falls, there will always be a lot of money coming in to boost the price rise, and there will always be the shadow of operators behind
why is bitcoin so popular recently! Let's talk about my views:
first, there are a lot of myths about sudden wealth.
for example, the founder of reborn coin has become the richest man in the blockchain. Some people are worth hundreds of millions in a short time relying on bitcoin. In addition, people like baoerye are telling stories everywhere, from beef sellers to Rolls Royce mirage who can buy limited edition, Many people yearn for it
{rrrrrrr}
4. The title of bitcoin blockchain
the blockchain technology behind bitcoin claims to replace all centralized organizations, which is obviously a utopian plot, but utopia is often beautiful, although it can not be realized, but everyone goes for it
I think that bitcoin is actually a data logic in the guise of blockchain, and its existence foundation is very fragile. Once there is a problem, it will lose everything. Therefore, the risk of the currency market is too great, so we must be cautious if we want to enter the currency market
Before the era of blockchain, Nick Saab first proposed the concept of smart contract in 1996: a set of agreements defined in digital form, including agreements on which contract participants can execute these agreements< the basic idea of smart contracts is contracts (special transactions) that can be executed automatically (event driven) and written in code form on the blockchain
since the establishment of Ethereum smart contract, more than 90% of the contracts have been used to issue tokens, and the implementation of relevant business scenarios is still good. What is the future of smart contract? Here you can see the Bytom chain that just released the news and launched the smart contract. As the first public chain project to release AI consensus algorithm in MIT, Bytom, the original chain, released an intelligent contract based on utxo model on the 26th after the main network was successfully launched in April
different from Ethereum smart contract built on account model, Biyuan chain is the first public chain in the whole blockchain instry to build smart contract on utxo model. Biyuan chain also transforms and deepens utxo to support the operation of multiple assets. In addition, compared with the original chain, the smart contract adopts its own equity language, which is a Turing complete and interpretive high-level language. It can easily compare the assets on the original chain for operation, and flexibly integrate into various asset business scenarios
in addition to the release of contract language, more than the original chain has also released multiple contract templates, which are directly attached with clear business meaning. From these contract templates, we can directly see the scene of future commercialization landing, and can extend the imagination in a wider range
currency transaction contract
through this contract, users can trade a variety of assets in Biyuan chain and other people without going through a centralized organization. That is to say, some assets can be locked through the contract. Only when other users enter the specified amount of assets, can they unlock these assets
for example, a decentralized exchange is built on the basis of contract, through which the two parties who want to exchange different assets in different currencies can be matched directly. The transaction speed is fast, and only a very small transaction fee is charged
third party trusteeship contract
under the contract template, users can transfer the specified assets to the third party's account, and the third party decides whether to call the specified account or return to the original account. The third party trust trust trust agreement stipulates that the third party institution can only transfer the assets to the designated account or return to the original account, which prevents the possibility of the third party account from stealing. In the business scenario, it can be expected that an asset custody platform can be built on the basis of the trusteeship contract of the third-party trusteeship institution in the future, which can ensure the custody, transaction and circulation of users' assets through the double trust of the trusted third party and the contract
mortgage contract
that is, the borrower will borrow the assets, and the lender will mortgage the assets into the same contract, and the lender will obtain the borrower's assets. If the lender fails to return the borrower's assets at a certain block height, the borrower will automatically obtain the lender's mortgage assets
call option contract
in this contract, the asset issuer can sell an asset at a certain price, and the buyer can buy the asset at that price. When it exceeds the height of a block, the asset will automatically return to the asset issuer
from the above design of smart contract, we can see some advantages:
firstly, a variety of templates with business meaning provide convenience for the upper layer to build DAPP, and some core business processes can be realized without too much development; Secondly, compared with the original chain, smart contracts issuing assets have templates. Compared with different developers, the security risk under the standard template is much lower. In addition, the contract will be invoked as a sub contract than the original chain when creating the intelligent contract. The contract template changes or errors that will be invoked in the future will not affect all completed intelligent contracts, which is of high security value for the early intelligent contracts. p>
we can understand that using the ratio chain of the extended utxo model butxo to interact with assets as a new form of utxo not only avoids the emergence of data overflow and other vulnerabilities in the Ethereum account model, but also has flexibility, diversity and controllability
for Biyuan chain, the release of smart contract also marks the determination of its core, which will further promote the commercialization of the project
