Bitcoin modifies mining code

1.

bitcoin mining machine is the computer used to earn bitcoin

mining software is the algorithm of bitcoin

the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

unlike all 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 feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

extended data:

bitcoin has the following six characteristics

1. Decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Worldwide circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

2. Sorry
you can't modify this
because this source code records the development process of bitcoin along the way, the problems encountered in the mining process and the mining difficulty
there is open source code to mine, so no one can change it

Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it

mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash

and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on

extended data:

mining risk:

1, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

2, system risk

system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin

special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below

this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high

so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers

5. Let's put it this way. Seven years ago, it was ok, but now it's not. All the old drivers quit. You didn't know until you saw the virus, did you.

6. Graphics card problem, even if you run successfully, you can't dig the mine. You need to use green gold graphics card. Green gold graphics card is a graphics card specially developed for mining. It uses 64 algorithm to decrypt a group of numbers, and you can get 25 bitcoins. Ordinary graphics cards are developed for games and rendering, green and gold graphics cards are developed for computing, not the same level.

7. My friends and I have bought it. It's easy to use. If you are a novice, it's worth recommending. The software is also very good

8. Sorry, you can't change this, because this source code records the development process of bitcoin, the problems encountered in the mining process and the difficulty of mining. Only open source code can mine, so no one can change it

Two way opening in futures means you can buy or sell

< H2 >

futures trading can be two-way trading, futures can buy more or short. When the price rises, you can buy low and sell high; when the price falls, you can sell high and buy low. Long can make money, and short can also make money, so there is no bear market in futures. In a bear market, the stock market will be depressed, but the futures market will still be prosperous and the opportunities will remain

the day of futures settlement can be one week later, one month later, three months later, or even one year later. A contract or agreement to buy or sell futures is called a futures contract. The place where futures are traded is called the futures market. Investors can invest or speculate in futures

{rrrrrrr}

< H2 > extended information:

basic system of futures

1. Position limit system

position limit system refers to the system that futures exchanges limit the number of positions held by members and customers in order to prevent manipulation of market prices and excessive concentration of futures market risks on a small number of investors. If the limit is exceeded, the exchange may close the position or increase the margin ratio

Large account reporting system means that when the speculative position of a certain type of position contract of a member or client reaches more than 80% of the position limit (including the principal) specified by the exchange, the member or client shall report its capital and position to the exchange, and the client shall report through the brokerage member
