[description of private key of bitcoin wallet]:

1. Wallet encryption refers to automatically encrypting and storing the wallet with private key. The official bitcoin client supports wallet encryption since version 0.4.0. The encrypted wallet will prompt you to enter your password every time you pay. If the password is wrong, the client will refuse to pay

2. If you replace it with the earliest backup wallet (wallet. DAT), you can still trade normally. Considering the principle of bitcoin, it can be concluded that as long as there is a private key (wallet), you can prove that you are the legitimate owner of the wallet. No matter whether you encrypt or delete the wallet (the core is the private key corresponding to an address), you can't deny it

3. When backing up the bitcoin wallet, you should also pay attention to the existence of bitcoin payment change mechanism (for example, if you send 50 BTC in a complete 100 BTC to an address, the system will send 50 BTC to the other party's address, and return 50 BTC to a new address of your client, which will not be directly displayed in your address list)

4. After sending bitcoin to other addresses 100 times or using 100 different addresses to receive bitcoin, please back up your wallet again, otherwise the returned and received bitcoin will be lost forever. In addition to encrypting wallets, users can also generate offline paper wallets and brain wallets

1. Cryptocurrency hackers

the hacker behavior of cryptocurrency exchange is the main reason for the loss of bitcoin. Exchanges are a hot target for cyber criminals, accounting for 27% of cyber attacks in 2018. Mt. GOx was the first high-profile cryptocurrency hacker, but since then, many major exchanges have been hacked, including bitfinex, bitstamp and, more recently, cryptopia, the cryptocurrency exchange in New Zealand, which lost 9.4% of its total positions

Malware

the malware on torrent website and Google play store are used to steal passwords from vulnerable categories. For example, there is a malware clipper that uses users' behavior of ing and pasting wallet addresses to steal passwords. For example, if you send BTC to an address, you usually and paste the address, because it is a long string of random characters, clipper malware will exchange wallet addresses, which means that when you paste, you will send encryption to the wrong address

has completed payment in the early days of mobile payment, it has been through the input of payment password or fingerprint. But now Ma Yun's Alipay has opened a quicker and more convenient way, that is, brush face payment. P>

Alipay has already done the payment method of face recognition through camera. We have to wonder that the progress of high technology brings people convenience and quick, which is really very attractive, so that people do not need to take out the mobile phone operation.

there is no need to worry about this. In fact, it's just like using a mobile phone to brush your face and open your mobile phone. You can't and can't unlock your mobile phone just by using people's photos. Of course, people who are curious about this will take photos to do experiments, but this photo is not their own

someone took out a picture of Ma Yun's face and scanned it. They thought that he would brush his face successfully or that some of Ma Yun's eggs would happen. However, no matter how many times he did it, it didn't work. It just showed that he failed to brush his face. In fact, the payment wire has been very stable, and the payment security we are worried about has been taken into consideration by the technical personnel and is now in use, so we can use it safely

6. It can be split, and one becomes 1000W

7. We can't study this thing. It's all done by those digital scientists. We only know how to buy or sell it. If it's stolen by others, it's not caused by ourselves. For example, if you're in the exchange, you can get compensation. If there's a wallet, it's your own business. No one can steal it. Only you know the private key
