Will bitcoin light wallet be traced
stolen
mark kalpler, chief executive of mt.gox, bowed his apology at a news conference held in Tokyo yesterday, saying that "the loss of bitcoin is e to a loophole in the company's system"
a lawyer for Mt. GOx said that almost all the bitcoins traded on the platform were stolen, including about 750000 bitcoins in the user's trading account and about 100000 bitcoins in Mt. GOx's own account. According to the trading on February 28, the loss is estimated to be about $467 million
according to media reports, mt.gox trading platform had more than 1 million accounts at its peak, mainly from customers outside Japan, including many users trading more than US $10000. Some bitcoin investors have rushed to Tokyo from overseas in an attempt to recover trading funds from Mt. GOx
on February 7, e to hacker attacks, mt.gox temporarily stopped the bitcoin extraction business, causing transaction confusion and user dissatisfaction. From the noon of February 25, users cannot log in to mt.gox trading platform. The home page of the website then pasted a "notice to customers" to suspend all transactions
Li, a native of Hefei, spent 140000 yuan to buy 124 bitcoins in October this year. Afterwards, Li joined some chat groups of bitcoin players to pay close attention to the bitcoin market. On October 22, a person named Michael in the group took the initiative to chat with Li and asked him if he was mining“ I won't, and I won't get any money. " Mr. Li replied. Michael repeatedly urged Li to have a try and sent him a "mining tool", claiming that he could use the tool to dig more bitcoin. In the subsequent chat, Michael constantly reminds Li to put bitcoin in his wallet, saying that the trading website is not safe“ From time to time, there are news that trading websites are closing down and running away. What he said is quite reasonable, so I believe him. " Li told Anhui Business Daily
100 bitcoins disappeared
Li received and installed mining tools. On the evening of October 26, he was inced by Michael to put 100 bitcoins in his wallet. However, when the bitcoin in the E-wallet just reached 100, it suddenly disappeared. Li suddenly panic God, and then contact Michael, the convenience of invisible disappeared
Li told reporters that at present, a bitcoin costs about 5000 or 6000 yuan, and 100 bitcoins are worth 500000 or 600000 yuan. Afterwards, Li reported the case to the police. However, to Li's disappointment, because bitcoin is a virtual currency, there is no relevant domestic law to regulate and protect its transactions. The police did not file a case“ Now, this man named Michael is still active on the Internet. He's just taking advantage of the law. " Li told Anhui Business Daily
there is a Trojan horse in "mining tools"
How could Li's bitcoin disappear? 360 security engineer contacted him and tested Michael's "mining tool", and found that this tool is a very popular "bitcoin robber" Trojan horse this year. According to the analysis of 360 security center, most of the "bitcoin thieves" Trojans are disguised as mining tools, simplified wallets and other compressed files. Once a player is recruited, the Trojan will automatically search for bitcoin wallets and steal them through e-mail, hacker remote control and other means.
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
however, it has not been fully and effectively regulated at present (as of March 6, 2019)
if we understand bitcoin as a kind of "currency", then it is equivalent to US dollars leaving the United States. Usually, after the US dollar leaves the United States, banks in other countries will help manage it. However, it is impossible to count the scattered us dollars that are neither in the United States nor in the hands of banks and other financial institutions. For example, in some areas of Africa where there are no banks, the US dollar is used
these scattered us dollars are equivalent to bitcoin
how to regulate these scattered us dollars
generally, in addition to controlling the issuance of US dollars, US dollar regulation also controls the circulation and usage ports. The Federal Reserve controls the number of new currencies issued each year according to the flow and damage of dollars abroad. At the same time, we should supervise the inflow and outflow of US dollars, so as to keep us dollars in an environment that can be roughly traced, so as to facilitate the issuers to count the total amount, so as to avoid excessive inflation or deflation
in fact, these scattered us dollars exist in some deregulated environments. Although they are out of control, they will not affect the overall economic situation
If anyone wants to influence the international economy through these scattered us dollars, then it must enter the existing regulatory system. In this way, these scattered dollars are regulated
for bitcoin, we can also learn from these forms of regulation
first of all, from the point of view of the issuing end, although the total number of bitcoin is now 21 million, it is also "set before" and cannot be changed
recently, it has been mentioned that the 21 million bitcoin limit should be abolished, which means that the issue of bitcoin is not stable. Therefore, it is necessary to control the issuance of bitcoin from the development end
you need to get inside the development side and become a core developer
Second, monitoring from the circulation link. In fact, this is the most difficult monitoring at present, because the blockchain is anonymous, the user is anonymous, and the receiver is anonymous
even though we can trace the circulation path of bitcoin by technical means (for example, we can know that a transaction is sent from a small house in the United States to a commercial building in Germany), it is only a drop in the bucket for tens of millions of users in the whole environment. How to trace and manage the overall transaction data is a huge problem
you can't know from the transaction data whether the user is engaged in illegal transactions
what should we do? Regulators have come up with a way to bind personal identity information to the user's real name, your exchange account number and bitcoin wallet address. But this is also a temporary solution, because it can only monitor the use of bitcoin in specific situations. An indivial can use multiple bitcoin wallet addresses. You don't know when he will apply for a new one
in terms of circulation, there is also a monitoring system to control the exchange channel between bitcoin and local legal currency. Banks in some regions do not provide financial services for users who exchange bitcoin for legal currency, and some countries and regions prohibit financial institutions from providing bitcoin and local legal currency exchange services
if users secretly exchange huge amounts of bitcoin, some clues can be found through the bank transfer records, so as to crack down on illegal acts in time. As for those who make little trouble, let him go
thirdly, restrict the use. This is relatively easy to achieve. For example, relevant laws have been issued to prohibit the use of bitcoin transactions. Although it's impossible to ban it completely, it's better than letting it run wild All over the world, it seems that what is forbidden is not completely forbidden
for example, before using bitcoin in public, you must use your real name, and you have to pay taxes to hold or use bitcoin
of course, it's OK for users not to do so, so it's better to use its assets in the dark
having said so much, now you know that bitcoin can be regulated, but it's not so well managed. Many measures have been taken, and it seems that they are not effectively regulated. Under what circumstances can bitcoin be effectively regulated? Users consciously report their holdings of bitcoin to the regulatory authorities. The regulatory authorities add some development functions to the bitcoin to achieve supervision, or they don't need to use it, so it doesn't matter at all
in fact, it can't be controlled so strictly, as long as it can't be controlled in the range of big waves. After all, there is light and dark, and there may be no gray space at all
new technology will surely have an advantage when it comes to living now.
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
