1. Find the code on the bitcoin system, and you can dig bitcoin if you find the code
every other time point, the bitcoin system will generate a random code on the system node, and all computers in the Internet can search for the code. Whoever finds the code will proce a block, and then get a bitcoin. This process is often called mining. Computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin profits more quickly, which is also an important reason for the recent shortage of graphics cards
extended information:
characteristics of bitcoin
The total amount is limited, only 21 million BTC
2. Anyone can issue bitcoin, but it is more and more difficult
3. Compared with the central bank currency, it is safer and almost impossible to be stolen
The transaction process is completely anonymous and cannot be traced
2. In the 1980s, a group of talented programmers explored this problem in the password mail group. In 1982, David Chaum proposed an untraceable cryptography network payment system. Eight years later, he extended this idea to cryptology anonymous cash system, namely ecash.
2 in 1998, Wei Dai's paper elaborated an anonymous and distributed e-cash system: B-money. At the same time, Nick Szabo invented bitgold and put forward the workload proof mechanism. Users solve mathematical problems competitively, and then publish the results in series with encryption algorithm to build a property rights authentication system. Hal Finney improved the mechanism as a "reusable workload proof"
3 on the basis of previous work, in 2008, the little-known "Nakamoto Tsung" published "bitcoin: a peer-to-peer cash payment system" in the cryptography mailing list of metzdowd.com. On January 3, 2009, bitcoin network was born, and Nakamoto himself released the first version of open source bitcoin client
since then, the monetary history of mankind has opened a new page.
3. The transaction direction of bitcoin can be queried. Bitcoin transactions will be recorded on the bitcoin
blockchain to find out the liquidity of bitcoin and from which wallet to which wallet. However, you only know which wallet is transferred to, and you don't know who the wallet belongs to. Bitcoin is both transparent and anonymous. Transactions and flows are public and will be recorded, but the person who trades is anonymous. Some scholars found that through the flow of bitcoin, transaction users can be found. They need to use certain technical means, and it is particularly troublesome. At present, it is only in the theoretical stage.
4. You can see the flow of the transaction, but you can't be sure who the account corresponds to in the real world
a bitcoin account is an address, and an address corresponds to an account. However, there is no need for identity proof to open a bitcoin account. Everyone can open a bitcoin account, and the number of bitcoin accounts can be opened is more than that of sand in the whole world. A person can correspond to multiple accounts, so I don't know which person this address corresponds to, that is, anonymity
5. Yes, if the password is too simple, or the security of your website is not enough, you may be tracked. Some websites have been stolen by hackers, not to mention personal accounts,
6. First of all, bitcoin is not untraceable. Every transaction goes all the way back to coinbase. Just because the address can be generated arbitrarily and infinitely, it has certain anonymity. Because of this anonymity, it creates opportunities for money laundering and extortion. Therefore, trading banks, driven by regulation and risk control, strengthen their identity verification. For example, the okex exchange requires users to upload ID card photos. In fact, this is also for the sake of user safety.
7. March 25 (Xinhua) Zhong, an employee of an Internet technology company in Haidian District of Beijing, took advantage of his position to steal 100 bitcoins from the company by inserting codes with the permission of the administrator to modify the application program in the company's server. Reporters learned from the 24 people's Procuratorate of Haidian District, Beijing, that the procuratorial organ approved the arrest of the suspect according to the law on suspicion of illegally obtaining the data of computer information system. P>
the prosecutor of the case, Ji Jingling, said that according to the criminal law of the People's Republic of China and the relevant laws and regulations, the suspect, Zhong Mou, violated the state regulations and used technical means to acquire data stored in the computer information system. His behavior had violated the criminal law and was suspected of illegally obtaining data from computer information system. The procuratorial organ has approved the arrest of the suspect Zhong Mou according to law. p>
8. Bitcoin BTC 2009 Satoshi Nakamoto is bitcoin / org ~ $24.3 billion is SHA-256; LTC 2011 coblee is litecoin / org ~ $3.6 billion is script infinite; IFC 2012 ifccion is ifccoin / ORG~$ $20 million is a script quark, qrk 2012, qrkcion is cgbcion / org - $10 million is a script zeta, ZET 2012 zetcony is ZET / org - $10 million is a script proof of work / POS
9. Bitcoin is certainly difficult to track back in the future, because this is the asset money lost, it is impossible to recover
