How to retrieve keystore from Ethereum Wallet

1. First, open IE, click Tools, click Internet Options, click Advanced, click restore default settings, click save, exit, re open IE
Second, open IE, refresh more than five times
Third, open IE, click Tools, click Internet Options, click delete file, click Clear history, confirm, save, exit ie, re open ie
all the above three methods have been tried, but they are not enough. Look at the following three possibilities:
1.
network speed problem
2.
virus problem
3.
computer configuration speed problem
the following solutions:
1.
check and kill whether there is a virus in the safe mode,
2.
or re install the browser to see if there is a similar situation
3.
try to replace other browsers
4.
try to link your network cable with other computers. If there is a similar situation, it means that your network speed is a problem
5.
the last move.. Repair the system
if the building owner says that it is not the above problem, it is possible that someone uses P2P terminator to control your network speed. In this case, you can take two solutions:
1.
Download anti-p2p terminator software to fight virus with poison
2.
use 360 antivirus software and browser, open 360 firewall, which can effectively resist the attack of controlling network speed

2. The smallest unit of bitcoin is "cong"
1btc = 1000, 1 = 1000, 1 = 1000 Cong

3. The condition of profit maximization in perfect competition is p = MC
MC = 3Q ^ 2-24q + 40
when p = 100, q = 10 (q = - 2 abandonment)
the profit is r = pq-ltc = 1000-200 = 800
thank you, please accept~~

First of all, remember whether the mnemonic words are at risk of loss. If it is possible to be known by others, please create a new token wallet at the first time and transfer the original wallet assets

if the wallet account in the cornerstone stage cannot be transferred, please contact the project party in time and ask the other party to assist in the transfer of token assets. If you are sure that it belongs to your own deletion or damage and is not known by others, you can choose to note the private key and log in with the private key

mnemonics is another form of plaintext private key, which was first proposed by bip39 proposal. Its purpose is to help users remember complex private key (64 bit hash value)

mnemonic words are generally composed of 12, 15, 18, 21 words, which are all taken from a fixed vocabulary, and their generation order is also based on a certain algorithm, so users don't have to worry about randomly entering 12 words to generate an address

although both mnemonic words and keysore can be used as another form of private key, different from keysore, mnemonic words are unencrypted private keys. Anyone who gets your mnemonic words can easily take control of your assets

So after users backup mnemonics, they must pay attention to three points:

1. Try to use physical media backup as much as possible, such as writing on paper with pen, and try not to take screen shots or photos and put them in networked devices to prevent being stolen by hackers

If one or two words are copied wrong, it will bring great difficulties to retrieve the correct mnemonics

3. Keep the backup mnemonics properly and take anti-theft measures

users can use the backup mnemonics to re import imtoken and generate a new keysore with a new password to modify the wallet password

extended data:

the essence of using imtoken to create wallets is to generate a set of mnemonics randomly. Due to the characteristics of decentralization, imtoken does not keep the privacy information of users' wallets. So after generating mnemonics, users must keep them by themselves. This group of mnemonics can dece the private key, the public key and the address of the wallet

according to the above instructions, if we want to find the mnemonic words, we need to know the generation process of mnemonic words: first, we make a 128 bit random number, and then we check the random number by 4 bits to get a 132 bit number, and then we divide it by 11 bits, so that we have 12 binary numbers, and then we use each number to look up the word list defined by bip39, So you get 12 mnemonics

calculate the number of mnemonics that can be generated, bip39 mnemonics thesaurus contains a total of 2048 words, 12 words in each group. For example, by analogy, the amount of sand on earth is about 1, followed by 18 zeros. If we can generate one million mnemonics per second, we can generate 3.1536 e + 13 mnemonics per year, which takes about 1.6715937e + 26 years to traverse all mnemonics. Therefore, brute force cracking is impossible

if all mnemonics and private keys are lost, they can't be recovered by brute force cracking, because imtoken's decentralization can't be recovered from us. However, if the mnemonic words are lost and the private key is still kept, the use of the wallet will not be affected
