Bitcoin split mining
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 />
BCC mining and bitcoin mining are the same, the only difference is the dynamic mining strategy
when BCC was just born, it continued the mining difficulty of BTC. The miners lost money for mining out of belief. At the beginning of bitcoin's birth, they even proced a block within 12 hours. In order to ensure the stable development of BCC network, BCC adopted the strategy of dynamic adjustment of mining difficulty, which can ensure that the block speed of BCC can well adapt to the decline of computing power
BTC is a difficulty adjustment for every 2016 blocks, while BCC adds a rule of "if the MTP interval of the past six blocks is greater than 12 hours, the next difficulty will be reced by 20%". At present, the mining difficulty of BCC has been reced a lot, which is about 13% of that of BTC. BCC's current block speed is close to an average of 10 minutes out of a block
mining principle of BCC:
the previous life of BCC was bitcoin. Before the bifurcation, the data stored in the blockchain and the running software were compatible with all bitcoin nodes. After the moment of bifurcation, it began to execute new code and package large blocks, thus forming a hard bifurcation on the chain. At present, BCC is still a futures, which will be officially split into a new currency on August 1
security problems faced by bitcoin:
the first security threat of users comes from the user activated hard fork or uahf - all BTC holders who control their private key get an equal number of BCCs at the time of fork
that's the problem: there are many domestic trading platforms designed for bitcoin, but it should be noted that many investors use third-party transactions or unsupported software wallets, but the investors themselves do not control their private keys, so it is the third-party trading platform that finally receives the new currency. Some platforms will inform customers, while others will not
many investors have transferred their assets to the supported bitcoin wallet a few hours before the hard fork, while investors without independent wallets have to wait
there are many opportunities for phishing attacks or other malicious attacks, especially considering that most successful malicious attacks against bitcoin are focused on controlling private key or hacker exchange, rather than directly attacking currency. About the security of bitcoin, you can also add your own wechat seciot to communicate
BCC is very similar to BTC in technology, adding greater blocking and transaction replay protection, and the latter is in a new form of signature. Bitcoin cash transactions use a new sight_ Fork ID, which prevents bitcoin cash transactions from being replayed on bitcoin blocks
the new hash signature also brings additional benefits, such as the input value signature improves the security of hardware wallet and eliminates the second hash problem. In short, it is theoretically safer than BTC, and its purpose is to start and use faster and more convenient
However, BCC does face a major threat, that is, most attacks, that is, the security risk of a single entity acquiring more than 51% of the network processing power. At the same time, the common enemy shared by the two blockchains is interrupt attack. Most attackers use network interrupt to split the network to improve the probability of successat the same time, partition network and network delay attack are threats. According to the latest research paper, for the so-called distributed network, it is easier than assumed, and 20% of bitcoin nodes are hosted in less than 100 IP prefixes
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
speaking of bitcoin, it can be hot recently. The Internet is discussing this mysterious currency everywhere, even in the economic journal. Newspapers are discussing the feasibility. Bitcoin is popular among computer geeks. These people are yearning for freedom. It is said that when Nakamoto published his paper, bitcoin has become increasingly popular. Many foreign websites and even shopping have accepted bitcoin payment, but domestic ones are relatively few. The value of bitcoin is relatively high now. It is worth more than 300 US dollars and more than 1000 RMB yuan, which is very attractive. But it is just a stock, which goes up and down. It's more risky than special procts. Please be careful when you enter the trade
today, I'll write down my experience and tools in bitcoin exploration. I'm also a novice. I'd like to share with people who love bitcoin
1. Download your bitcoin e-wallet first. There is bitcoin client on the Internet. It doesn't need to be registered. It is bound to your computer by default. After downloading and installing, it will change your network data block. This is enough. I heard that it is to download all the information of network nodes. It's global. How big should it be? I've updated it for several days and finished downloading the data block
bitcoin client interface:
2. The interface is relatively simple. With this client, you can make bitcoin payment and collection. You can see a string of numbers and letters below by clicking on the circle in the figure below. You can the string and send it to others. If you give the bank card account number to others, they can pay. You can click "send currency" and paste the account number sent by others to pay for bitcoin. There is no third party in this process, So it's safe
3. How to mine is also an important way to proce bitcoin. Mining tool is guiminer, it is a green package, that is, folder, do not need security, download it directly decompression can be used, find the icon below, double-click to run
interface:
4. If you have a tool, you need to find a good place to proce minerals, that is, a mine pool. Now the output of bitcoin is less and less. If you dig bitcoin, you don't know when and when. If you are a Galaxy series supercomputer, let's talk about it separately. Personal computers can be ignored. There are many mines, But it is known as deepbit, the world's largest mining pool of bitcoin. Its website is
https://deepbit.net/ Log in to the website to register an account. Click my account
5, enter my account information, here you can see your miner information, how much bitcoin your account has, C contribution
6, specific settings of my account< br /> 1、< Your bitcoin address to receive payment: & gt; In the box, enter the address where you accept bitcoin. Don't write it wrong, or you'll be digging for nothing. The picture and text above have said that
2. Minimum value of automatic payment: set by yourself. When you have so much money in the mine pool, the website will automatically type the money to your bitcoin account address set above. You see, the above settings are important
3 to set up miners, click create new vorker, Chinese is to create new miners, miners can help your mining workers, you can set up more than one, and then dig in a lot of computers, the effect is more obvious, the income is more rich
just write the name casually, to write in English, foreign things better write in English
write the password by yourself, don't write it too long, it's just simple, it's not important
failure detection threshold (1-3600 minutes): just write 60,
send email notification when the miner doesn't work? *: Choose decisively, refuse spam,
payment method for miners: choose decisively, pull according to proportion, pay more for more work, which is in line with human development
finally, click Sava setting to save your miner, and you can see your miner's information when you return
7. Fill the miner information into the mining tool guiminer,
file - & gt; new opencl miner-> Fill in your favorite name - "sever" select deepbit - "user name to fill in the miner's, remember to connect your registered account with your mailbox and miner's, there is a password on it, you know, device is to choose what hardware you use to work, usually with a graphics card, select the graphics card you want to use, if you can't find it, remember to update the graphics card driver, Then start mining. You can sit and wait for the ore to be collected. The specific speed depends on your computer configuration
note: there are many ore pools and tools, but I won't introce them to you, just because I use what I said above. Whoever uses knows, there will be a place to speak, and I may not understand others. Be careful, the electricity bill is not enough. If you really have it, you can buy and sell bitcoin on China bitcoin network and exchange it for real gold, right.
Bitcoin is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now
so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end
1. Mining can not only proce bitcoin, but also guarantee transaction information
similarly, a mathematical system contains 21 million mathematical problems, so we need to constantly seek the special solution of each mathematical problem through a huge amount of calculation. In addition, the special solution is unique
mining can not only increase the supply of bitcoin money, but also protect the security of bitcoin transactions and prevent fraulent transactions. In terms of process, bitcoin network is a point-to-point payment system, and anyone can trade through the transaction program
in order to ensure that the transaction process is truthfully recorded, the role of "miner" is required to be responsible for recording bitcoin transaction information. The time interval is 10 minutes. The best recorded transaction records among miners will be packaged and stored in a new block, and the corresponding miners will also receive a certain amount of bitcoin rewards
2. The mining process is extremely complex, which is beyond human power
the specific process is as follows. When a miner listens to the transaction, he will first verify the transaction information. The verified transactions will be recorded by miners and stored in their own database. There may be thousands of miners in the world doing the same thing, but every ten minutes, only one miner has the right to create a new block, so that the transaction information recorded by himself can be recognized and stored permanently
next, miners need to fight for the right to keep accounts. This is a competition of computing power. The core of this competition is to use computers to complete a large number of calculation tasks and find a super difficult random number. This random number is the special solution of the equation mentioned in the first paragraph. The miner who calculates the correct random number first wins. According to the rules of the game, the probability of a miner getting the accounting right is directly proportional to the proportion of his computing power in the total computing power of the whole network. In other words, the probability of finding the random number is equivalent to throwing out 100 million dice, and the total number of dice is less than 150 million. Therefore, mining requires a large number of computers, installation of specific algorithm software, repeated operation day and night, not human
3. Bitcoin mining is actually "villagers' bookkeeping"
maybe some netizens still don't understand, let's take an example. In a village, the villagers often borrow money from each other, even if they write a written document, there is a risk of default. Then, every time there is a loan behavior in the village, we will use the village trumpet to inform everyone that all the villagers (miners) will record all the transaction records in their own account books.
Bitcoin is an electronic currency proced by open source P2P software. digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin.". Short for: BTC
bitcoin does not rely on a specific monetary institution. It is generated through a large number of calculations of a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin is a relatively mainstream digital currency, which can be properly invested. There are risks in the transaction. You can invest cautiously. You can search the fire coin, coin security, OK, dobby trading platforms on the Internet, which can trade bitcoin. These are relatively large trading platforms. Invest in mainstream digital currency, do not invest in counterfeit currency or air currency< br />
Bitcoin mining is a process of using computer hardware to do mathematical calculation for bitcoin network to confirm transactions and improve security
