BTC backup a large number of private keys
{rrrrrrr}
bitcoin (BTC) is a digital currency with a total amount of 21 million. It has the characteristics of decentralization, globalization and anonymity, just like the Internet. It means that transferring bitcoin to the other end of the earth is as simple as sending e-mail, low-cost and unlimited. Bitcoin is also used in cross-border trade, payment, remittance and other fields
the liquidity and limitation of bitcoin determine that bitcoin can act as a monetary function equivalent to general equivalent, or as a measure of money, but this measure is not a physical measure like gold, but a digital proct
related concepts:
1. Address
the address of bitcoin world looks like this. The address itself is just a string of codes, just like your bank account number 321 million 3288372, which is used to mark an account. Everyone can have countless addresses. The address is public
2. The bank records how much money there is in the bank account
the amount of money in the bitcoin address is recorded by the whole bitcoin network. Each complete bitcoin data will record how many bitcoins are stored in this address
each node participating in the bitcoin network can save a complete of bitcoin data, and everyone has a backup on hand to prevent counterfeiting
3. The key (private key)
the key is another string of characters you only know. The key is used to operate the money in the bitcoin address. Key and address are the relationship between a key and a lock. Each address has only one password, and each password also operates a bitcoin address
with the key, you can control the money in the bitcoin address and pay to anyone. The key should be absolutely safe. The lost or deleted key can never be found, and the money in the corresponding bitcoin address can never be used
the key needs to be kept absolutely secret. Anyone who knows the key can steal all your bitcoin
4. Wallet
the transaction process of bitcoin will involve a lot of complex calculations. In order to simplify the operation, we have made wallets. The wallet has client software on the computer, and also has an online web version. The function of the wallet is to pay with a little touch, and the complicated calculation behind it is left to the wallet to complete
5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />
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
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.
the wallet file of the wallet client is the database for storing the private key of bitcoin. Both the private key and the public key are stored in the wallet.dat file of the bitcoin wallet. Keeping wallet files securely in multiple locations prevents bitcoin from being recovered in the event of an accident
wallet file location
Windows XP - C: & # 92; Documents and Settings\{ username}\ Application Data\ Bitcoin\ wallet.dat
Windows 7/8 - C:\ Users\{ username}\ AppData\ Roaming\ Bitcoin\ Wallet. Dat
Mac OS X ~ / library / Application Support / bitcoin / wallet. Dat
linux ~ /. Bitcoin / wallet. Dat
the above is the default wallet directory of bitcoin core client. If the data directory is specially set, you can search the keyword "wallet. Dat" through windows to the wallet. Dat
my address:
There is no limit on the total amount of use, but there is a limit in theory. It depends on the number of public key digits. A simple high school permutation can calculate the number (an astronomical number); A public key is a very good random number generator. Under the restriction of long enough public key, it is impossible to have plicate public key in theory
the following is the calculation comparison of different length keys in intercepted professional books
Analysis of the role of adventure and mining skills, what are the roles of skills in adventure and mining mobile games, and what are the differences of different skills. Today, I'd like to introce the role of adventure and mining skills{ RRRRR}
< critical hit
class A certain probability causes 150% of the attack power & mdash; 400% of the damage. Some skills can't be dodged, some skills can only be triggered when the enemy's combat power or own combat power is lower than what percentage, and some skills can't be launched until a certain round
< percentage
class It has a certain probability to damage the enemy's current combat power percentage. Heroes with this skill are best placed in the front row. The earlier you trigger, the better. Armor can resist the damage of this ability
< recovery class
It has a certain probability to recover the combat power of your damage percentage or the combat power of the enemy. Hit damage will be resisted by armor, but recovered combat power will not count as armor. When you regain your combat power, you will ignore the enemy's armor
< four dimensional
class Increase your four dimensions, attack, defense, dodge and king
