Is it true to crack bitcoin vulnerability

1.

bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. 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 decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals

2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked

4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

2. First of all, let's talk about the background. The basic principle of bitcoin "account" is key public key address. You can roughly understand it as "key box box number". Now is to start from the box number or box to crack the key
there are basically two kinds of attacks, one is dictionary attack, the other is brute force attack
dictionary attack is to use common passwords and their simple variants as keys one by one. As long as your pass phrase is not hard enough, the possibility of successful attack is very high. So if you want to use this, you need to popularize the knowledge of cryptography first, and don't think it's very safe to add a long password
if you don't use the wallet generated by pass phrase, you can only crack it violently, which is equivalent to enumerating all the possible keys. At present, this is impossible, even if the electronic computer is becoming more and more powerful. However, quantum computer can do it theoretically, but don't worry too much. If such a powerful quantum computer comes out, it will not only endanger bitcoin
at the same time, bitcoin has a second layer of protection: if an address only accepts bitcoin but does not output it, its public key is confidential, that is to say, no one else can see the box, only the box number. At present, the process of decing the box from the box number can't even be done by quantum computer. In other words, if there is a quantum computer, bitcoin has a last line of Defense: it's temporarily safe to transfer your money to a new address
finally, some time ago, the wallet generated by the Android client was attacked because of a bug in the underlying random number generator. In fact, this function is not random securerandom, which Google quickly admitted and fixed. It's hard to say whether this kind of thing will happen again, but I don't think we need to worry too much.

3. No, there are several reasons why bitcoin was stolen
1. A stolen bitcoin can't be retrieved, and if it's lost, it's lost.
2. Bitcoin has transaction records, but the address is hidden, and you can't find an indivial.
3. Every bitcoin has a key, and only if you have this key can you be admitted to own bitcoin. However, if bitcoin is stolen or lost, your bitcoin will disappear completely
therefore, the theft of bitcoin does not belong to cracking, it may be e to internal personnel.

Bitcoin is a kind of virtual commodity. In recent years, the price of bitcoin has been soaring. Recently, after more than three months of investigation, the Public Security Bureau of Zhongyuan Oilfield in Henan Province successfully cracked the first case of bitcoin theft in China

on July 27 this year, the Public Security Bureau of Zhongyuan Oilfield in Henan Province received an alarm from Wu, a resident under his jurisdiction, saying that he had lost more than 3.4 million yuan worth of bitcoin in his Internet wallet. Wu is a professional investor and has been investing in bitcoin since 2016. In early 2017, he was drawn into a wechat group of bitcoin investors

the victim Wu: at the end of the day, he said he was also responsible. Although he said that he taught me to lose my coin, he was also kind-hearted. He said that he would compensate me for 10 (bitcoin), saying that he could only bear his part of the responsibility. Later, he used Alipay to transfer money to me. If it had nothing to do with him, how could he casually accompany others for more than 100000, not a small number

after cracking the password stealing software, the police arrested the suspect

after preliminary investigation, the police determined that Dai, the leader of wechat group, was suspected of committing a major crime. On August 9 this year, the police controlled Dai in Shanghai. In Dai's home, the police found 27 bank cards and multiple computers. In one computer, as like as two peas, the police found a net wallet software that was exactly the same as the victim's use. p>

it turns out that Dai is proficient in software programming. After cracking the downloaded genuine wallet software, he adds a program to transmit user name and password to steal bitcoin. Once someone deposits bitcoin in the E-wallet, he will know the other party's account name and password, and transfer bitcoin in the E-wallet. He distributed the stolen bitcoin in hundreds of network wallets, transferred it back and forth, and sold it at a low price on the trading platform after confirming its security. In this way, Dai has committed three crimes involving more than 20 million yuan. At present, the police have found out Dai's account and frozen it, recovering more than 2 million yuan of stolen money

according to the police, bitcoin is a virtual commodity, which is difficult to be recovered once there is a problem in the transaction

Su Haizhou, leader of Criminal Investigation Detachment of Henan Zhongyuan Oilfield Public Security Bureau: bitcoin trading platform our country has closed all three platforms before the end of October 2017. At present, the country only recognizes bitcoin as a virtual commodity, not as a virtual currency. So you need to be careful if you want to invest in bitcoin

5. Caibi tix is good. It can be said that caibi tix is the first potential virtual currency in 2018. Many people buy it, and its appreciation is fast.

6. Theoretically, it can be cracked, but it's just a time-consuming problem. If you think about the cost of mining, you should know the difficulty of cracking. To protect bitcoin by means of encryption must make the cracker pay a much higher price than mining, otherwise everyone can get it by cracking rather than mining

Recently, Haidian police in Beijing cracked a case of destroying computer information system. The suspect Zhong used his administrator's authority to modify the company's computer applications, stealing 100 bitcoins, worth millions of yuan. Before he could sell the stolen goods, Zhong was arrested by the police. At present, Zhong was detained for the crime of destroying computer information system

according to the police, after stealing bitcoin, Zhong originally wanted to go to a foreign website to sell it. Because he didn't know which website could operate, he found an application of "bitcoin wallet" on the Internet and saved the stolen 100 bitcoins. It was said that there was also a "core money package", which could clear the track of stealing, and then moved 10 bitcoins to deposit. After the police work, Zhong returned the remaining 90 bitcoins to the company, but the 10 bitcoins stored in the "core wallet" could not be found

At present, the suspect Zhong has been detained by Haidian police for the crime of destroying computer information system, and the case is under further trial
