once your key is disclosed, others can transfer your bitcoin

The private key of bitcoin wallet cannot be viewed online. Bitcoin exists on the platform. To download core or classic is the real wallet, and then you can view it

[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

4. The private key is your bank card password, and the address is your bank account number, but the private key is more important. With the private key, you can push out the address. If you forget the private key, you will lose everything. The signature is personalization, plus a verification procere. The wallet is a small ATM, which can be sent after the update. If the wallet file is saved, it will be OK. BTC China is OK, and you can buy money.

5. This is the order of importance: BTC private key, wallet security password, BTC address
the private key is everything and must not be told to anyone
as long as there is a private key, you can re import the wallet and reset the wallet security password
a BTC account can have many addresses, so the least important one is the address. No matter how unimportant, you can't just tell others.

6. Public private key is peer-to-peer encryption. You can see RSA encryption

only the private key can decrypt the content encrypted by the private key
only the public key can decrypt the content encrypted by the private key
here, the public key is your bitcoin ID, and the private key is your wallet

when using bitcoin, you should take care of your wallet, and you'd better encrypt it with a password, You can use your bitcoin

there are many bitcoin trading platforms on the Internet, and you can find a lot of them by Google search
generally, you need to mine bitcoin, and there are also mining platforms on the Internet, but now the income is low, and the display card is burned

7. The essence of BTC is a distributed, algorithm-based and public network account book (just as the essence of a bank is a private account book which is not publicly controlled by the central government). The wallet (private key) is actually the right for you to modify the account number (public key or bitcoin address) in the account book. The wallet corresponds to the account number. In fact, the specific wallet file contains more than one private key information, which can be copied to other places for use. As long as you have the private key corresponding to the account, it's like having the password of the bank card. Understand the above, you should also understand the answer to your question - B has 10btc on the address. It's not about the computer. This may be better understood by you: wallet = private key (bank card password) + public key (bank card number) BTC network system = Bank, access to BTC network with wallet = bank card inserted into ATM and certified, payment = transfer to other accounts.

First of all, you should imagine a concept of "wallet" in your brain. Your bitcoin is in your wallet. A wallet can contain many... Many addresses. The form of the address is the form

with the bitcoin address generated in the bitcoin wallet, you can receive bitcoin from others, and you can also transfer the bitcoin in your account to the bitcoin address of others. Bitcoin address, like bank card number, has the functions of payment, transfer and withdrawal. However, when transferring money, you can only transfer money by knowing someone else's bitcoin address

if we simply compare a bitcoin wallet to a bank card account, then the address of the bitcoin wallet can be regarded as a bank card account number. The difference is that bitcoin addresses can not be stored on the network, but also exist independently of your wallet

< H2 > extended data:

bitcoin address is a string of 26 to 34 letters and numbers. It looks like a lot of messy code. To put it bluntly, it's just like your bank card number. All transfer records of each bitcoin address can be checked through blockchain query, which is open and transparent

address generation of bitcoin Wallet: 256 binary digits are randomly selected to form the private key, and then the address is generated by encryption function. This generation direction is unidirectional. That is, you know that the address cannot be decrypted to calculate the private key. At present, the computing power of human computer can't be cracked, so you can publish the address on the Internet with ease

9. Applications that support bitcoin protocol can correctly convert this string into the private key of bitcoin, and then convert the public key to get an address. If there is a corresponding bitcoin on the address, you can use the private key to spend the above bitcoin.
