What evidence do bitcoin cases need

1. Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to the algorithm to "mine" bitcoin. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. By 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

2. It's illegal to steal bitcoin. The public security bureau can arrest you. There are also many cases of fraud using bitcoin. In China, the central bank defines bitcoin as a special Internet commodity, which denies its monetary attribute, but people can buy and sell it freely at their own risk. Zhou Xiaochuan, the governor of the central bank, said that bitcoin is a tradable asset, just like stamps. Now, do you think it's illegal to steal bitcoin?

Bitcoin blackmail refers to an email received in the mailbox. The content of the email generally includes: malicious software on the computer has captured the recipient's indecent photos through the webcam, knows the recipient's real password, etc., which makes the recipient fear and demands to pay the sealing fee in the form of "bitcoin"

if the blackmailer passes the email, he will take the next step, and he does have a lot of important information. In any case, don't transfer bitcoin to blackmailers. It's a bottomless hole. It's a good choice to keep all the evidence and report to the police. The above personal opinions are welcome to be criticized and corrected.

Transaction mode of bitcoin

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

Bitcoin has become the most popular cryptocurrency in the world. Some countries allow the transaction of bitcoin, but some countries prohibit it. China belongs to the latter. Why does China shut down bitcoin trading? Let's analyze this problem today

bitcoin does not have the function of trading medium in China, so it can not be called currency. At the same time, bitcoin has the function of storing value and has certain investment value. However, the rapid rise of the current price has formed speculative anticipation and may form a bubble in the future. Therefore, it is necessary to take measures ahead of time, which can also restrain some illegal acts of laundering money and transferring assets through bitcoin. p>

6. Whether bitcoin is legal or not depends on the attitude of monetary authorities
the further development of bitcoin may threaten the interests of traditional currencies, and currency issuers will not cede their rights to an open-source P2P algorithm. So governments are likely to outlaw bitcoin
once governments declare it illegal, it may cause huge fluctuations in its price in the short term. It could be a crash, it could be a surge. Because people at the bottom of the world are obviously resistant to their governments< At the same time, the ban by the government will lead to the closure of bitcoin trading platform. After the closing of the trading platform, bitcoin can only be cashed in private, which will have a great impact on its cashing ability< However, e to the characteristics of bitcoin itself, it provides an excellent channel for officials of various countries to accept bribes, launder money and transfer assets overseas. Especially in the trend that officials of various countries disclose their property, bitcoin provides a good way for them to hold huge property anonymously
from this perspective, some officials may actively promote the legalization of bitcoin< On May 7, 2013, officials from the US Commodity Futures Trading Commission (CFTC) said that they were considering whether the online virtual currency "bitcoin" could be applied to the agency's regulations. CFTC is the highest regulator of the derivatives instry in the United States. Bitcoin is known as a currency independent of traditional authority, and if it is regulated more, it may bring challenges to its supporters
CFTC mainly supervises derivatives contracts. Its responsibilities have been greatly expanded after the financial crisis in 2007-2009, and it also has full power to supervise retail foreign exchange dealers
Bart Chilton, one of the five members of the CFTC, said on Monday that he had asked the committee to consider regulating bitcoin to determine whether consumers need additional protection when using bitcoin[ 15]
the Hong Kong government has approved GBL electronic currency trading center to operate virtual currency exchange business, which will be an important milestone in the development of bitcoin. GBL virtual electronic currency trading center has completed the equity change and has the business scope of virtual electronic currency exchange business.

7. There must be fraud in digital currency investment. It's better to find formal institutions to invest, and don't trust high returns.

8. 1. Possible scope of infringement
the patent law stipulates that the scope of protection of a patent right for invention or utility model shall be subject to the content of the claim, and the description and drawings can be used to explain the content of the claim
the interpretation of the Supreme People's Court on Several Issues concerning the application of law in the trial of patent infringement disputes stipulates that the people's court shall examine all the technical features recorded in the claims claimed by the obligee when deciding whether the infringed technical solution falls within the scope of patent protection, The people's court shall determine that it falls within the scope of patent protection; If, compared with all the technical features recorded in the claims, the technical features of the sued infringing technical scheme lack more than one of the technical features recorded in the claims, or more than one of the technical features are not the same or the same, the people's court shall determine that it does not fall into the scope of protection of the patent right
it can be seen from the above provisions that if a proct is identified as infringement in the patent document, it must cover all the technical features recorded in the claim. Therefore, in order to obtain a larger scope of protection, the less content in the claim, the better, that is, do not add unnecessary content
the innovation of blockchain is usually associated with multiple executors, which is a systematic scheme that needs the cooperation of all parties. For example, if the data publishing node, blockchain network, authorization node, etc. are combined in a claim, it will be found that when the patentee wants to sue an executor for infringement, the party does not cover all the contents of the claim (at least not other executors), which leads to that although the party uses the innovative idea of the patent, it does not infringe. Therefore, in a claim, it is better to write the scope of protection around an executor< According to the patent law, except as otherwise provided in this law, no entity or indivial may exploit its patent without the permission of the patentee, that is, it may not manufacture, use, promise to sell, sell or import its patented procts, or use its patented methods, or use, sell or import its patented procts for proction and business purposes Promise to sell, sell and import the procts directly obtained according to the patented method
here we should pay attention to "for the purpose of proction and operation", that is to say, not for the purpose of implementation, no infringement. Therefore, when writing the claims, we should also consider who the potential infringement objects are, and the content of the patent right should limit them as far as possible, instead of including unnecessary objects (such as the devices used by the end consumers).

9. Virtual currency does not belong to electronic currency. There's a bit of a similarity. E-money is the electronic circulation of money, that is to say, the fundamental nature of e-money and money is the same. Virtual currency, from the beginning of q-coin game currency to the present bitcoin, bcbot and other digital currencies, belongs to virtual currency, which belongs to the activity of decentralization that has not been recognized, although digital currency also has some attributes of electronic currency.

I think we should pay attention to where the money comes from and through which channels it is hyped. In fact, it is necessary to find out. In fact, bitcoin has a great impact on the society, because the price of bitcoin has been very high and deviated from the actual value, So ordinary people in the process of speculation bitcoin, we must see clearly the current social situation

First, the price of bitcoin is too high

in fact, most people already know that the price of bitcoin is too high, because in about 10 years, the price of bitcoin has increased by tens of thousands of times, which is impossible for any asset, because the investment procts of Putong can only increase by about 10 times in 10 years, You can imagine how overvalued bitcoin is{ RRRRR}

in the society, the speculation of bitcoin has a great impact on the real economy, because a lot of money has flowed into bitcoin, and there are very few pre class resources in the real economy, so it must be a very big blow to the development of the real economy in the future. I think the country must solve this situation well, Only when more funds are channeled into the real economy can more wealth be created. The real economy is the field that our country must pay attention to in the future development and the foundation of our country
