Bitcoin error

1. Any bitcoin transaction is irreversible and can only be returned by the payee. This means that you need to pay attention to dealing with indivials and organizations that you know and trust or have established credibility. On their side, businesses need to control the payment requests that customers see. Bitcoin system can detect typing errors and usually won't let you accidentally pay to an invalid address. In the future, there may be other services that provide consumers with more choices and protection
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.

2. Change a machine to download and install synchronization again, or change the computer system.

At exchange: a few mistakes about bitcoin, do you know

bitcoin, in a way never seen before, has an impact on the field of financial services. Whether in a bear market or a bull market, it has always been an old topic

because the underlying technology of bitcoin has been blockchain for ten years, and the technology content is high, many people do not understand it well, thus forming many misunderstandings

misconception 1: bitcoin is too expensive, a few tens of thousands of yuan, just wait and see, too expensive to buy

in most people's cognition, bitcoin can only be bought whole, which isolates those who want to invest in bitcoin. But in fact, bitcoin is divisible, and the minimum transaction unit is 0.00000001. That is to say, you can buy bitcoin for 100 or 200 yuan

in the future, with the improvement of people's acceptance and recognition of bitcoin, as well as the expansion of application, the price of bitcoin will also rise

misconception 2: the government can not regulate, which is beyond the scope of legal jurisdiction

in the early days, bitcoin was the hard currency of the underground drug market, with a transaction volume of millions of dollars each time, and there was a black market nicknamed "Silk Road"

However, at the beginning of the emergence of new technologies, it is always difficult to have written laws to regulate them, such as the beginning of computer and network applications. But in the end, these new technologies will graally come under the jurisdiction of the law

at present, bitcoin trading has been regulated in the specific legal provisions of New York State and other states in the United States. In 2014, the IRS recognized bitcoin as taxable property, and the securities and Exchange Commission has recently carried out strong supervision on it, so it is absolutely a misunderstanding that bitcoin is not subject to legal constraints. China and Japan have also begun to actively write laws and regulations related to virtual currency

misconception 3: bitcoin mining is too difficult, mining machine is a waste of resources

bitcoin mining is an energy intensive process. Because of its decentralized nature, no one knows the exact amount of electricity consumed by this process, but at any given moment, it could be billions of watts, roughly equivalent to the output of large-scale power stations such as the Hoover Dam

However, if we compare these with the management cost of currency, we can see some problems. Although the current currency does not seem to consume much energy, the cost of protection is not taken into account. For example, the security personnel employed by the bank usually just look at the customers and "waste" a lot of money and manpower, not to mention the towering buildings of the bank and the huge price paid for the safe payment system. However, if there is no security system, theft will damage the entire financial system, so this operation mode is not a waste

misconception 4: users of bitcoin are anonymous, and law enforcement agencies are traceless.

Nakamoto Tsung, the founder of bitcoin, claims that bitcoin can protect users' privacy, because most bitcoin software will create a unique pseudonym for each trader; Because of its anonymity, outsiders can not easily grasp the identity of donors

in fact, most users will leave a written record when they trade bitcoin in exchange for legal currency, and the user's identity is recorded in the transaction service with good reputation. Therefore, if the law enforcement agencies really want to trace, there are traces to follow

to sum up, bitcoin is a digital currency based on blockchain technology. As an emerging technology, it has unlimited application potential. This kind of decentralized application without government credit endorsement may achieve information transparency, security and efficiency. However, hacker attacks occur frequently. It seems that only when technology progress and supervision are in place can blockchain technology be applied globally and truly convenient to all aspects of life

1. Bitcoin's long-term investors are turning into short-term investors

2. The transfer of wealth is behind the soaring price

3. Most of the transactions of bitcoin come from exchanges, and a large number of them are used in the real economy

Banks are not willing to cooperate with cryptocurrency companies and exchanges, and many operations are compliant

extended information:

purchase method:

users can buy bitcoin, at the same time, they can also use the computer to "mine" bitcoin according to the algorithm. When users "mine" bitcoin, they need to search for 64 bit numbers by computer

and then, by repeatedly solving mysteries, compete with other gold miners to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, it will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and 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

5. This problem I have encountered, I 2003 system under the wallet, found that the wallet data file is wrong! Thought it was a problem with the 2003 system! Specially modified 64 bit win7, error still! I don't know what's wrong! I feel that I have been following the upgrade of bitcoin wallet all the time! Up to now, it's 1.49M, but no matter how I make it, it's all a mistake! At first, delete all the block chains, only one wallet data file! After the update is completed, you can see that it is normal for a period of time. If you open the wallet for a long time, you will report an error again. After the error is reported, unless the reconstructed data is displayed normally for a period of time again! But still can't solve the problem! Back to the original just built wallet file, just set the password, just set up the collection address data backup out to use, the result is no problem! And all bitcoin is still there! By contrast, when using the 1.49M wallet data file, the record of the latest received bitcoin can't be written in, and then it's OK to look at the data backup file. Anyway, there are no recent transaction records, but there are so many bitcoins, so the error should be here! But I don't know how to solve this problem, I can only use the original wallet backup, fortunately, there is a 300 K backup at the beginning, otherwise it's finished! Now there is no problem, this problem has to be reported to the official!

6. If you are cheated, you can call the police, if not, you can't find it back. If you transfer to a wrong address, then this bitcoin will disappear. Bitcoin transfer is irreversible

7. I'm sorry to tell you that it did disappear

8. If the software is updated, the network display is slow. You can go to the official website to see if there is an update package. Generally, the app and the network do not support this. In addition, there is a problem with your network itself. A series of problems caused by poor signal will appear, and the software can't be opened. This kind of problem is common in general software, Change your mobile phone and download it to see if it's the same problem, then you'll know it's the same problem.

9. What it calculates at present should be the encryption work of bitcoin itself. In fact, it only encrypts the personal information of bitcoin users! It has no practical value before it has evolved to calculate the remaining computing performance of everyone to other valuable projects It's not obvious, unless you bring people in to make bitcoin appreciate, but first
