1. Ethereum wallet address is your bank card number. If you forget the address, you can use the private key, mnemonic words and keystore + password to import the wallet and retrieve it. Buying and selling Ethereum is even easier. You can open an account with $100 in the realm Kingdom, and then analyze the price. Buying up or down means buying in the right direction is profitable.
2. The term "difficulty" comes from
bitcoin, the pioneer of
blockchain technology, which is used to measure the average number of operations needed to dig out a block.
mining is essentially solving a puzzle. Different e-coins set different puzzles. For example, bitcoin uses SHA-256, lightcoin uses script, and Ethereum uses ethash. All the possible values of the solution of a puzzle are called the solution space. Mining is to find a solution among these possible values
these puzzles
3. If it's lost, it's better to post the lost advertisement
4. Ethereum wallet password
cannot be modified.
5. This question is very strange. I recommend you to see the introction of professional media
6. In go, the outcome is determined by the number of intersections. The intersection is the result of the intersection of 19 horizontal lines and 19 vertical lines in the chessboard × 19 = 361 points. In technical terms, these points are called "Mu" or "Zi". The last side with more mesh or sub number wins. But generally speaking, the black side should first paste 7.5 mesh to the white side to balance the advantages of the first hand, that is to say, the white side should add 7.5 mesh to compare with the black side. Note that the meanings of "Mu" and "Zi" are different from those mentioned above. Here, "Mu" and "Zi" refer to two different methods of calculating the outcome. Either method can be used, and the meaning is the same
let's first talk about the calculation method of "item": the difference between the number of items on both sides, such as 180.5 items on the black side and 180.5 items on the white side, is that the white side wins 7.5 items, because the black side has to post 7.5 items first
let's talk about the calculation method of "sub": half of the intersection point is 180.5 + 3 + 3 / 4 (half of 7.5 mesh). If one party wins by more than this number, the number of sub winning is the difference between the number of sub winning party and 180.5 + 3 + 3 / 4, which is the same as the above example, that is, white party wins 3 + 3 / 4.
7. No, the entry card is still R7 240, and the entry card will not be used for mining, so there is still a lot of inventory, and there will be no new one for the time being
8. Keysore file is a file format (JSON) in which Ethereum wallet stores private keys. It uses user-defined password encryption to protect the wallet to a certain extent. The degree of protection depends on the password strength of the user encrypting the wallet. If the password is similar to 123456, it is extremely insecure
There are two points to note when using keysore:
1
2. Be sure to remember the password for encrypting keysore. Once you forget the password, you will lose the right to use keysore, and imtoken can't help you find your password, so be sure to keep keysore and password properly
keysore style
PS: keysore's password is unique and unchangeable. If you want to change the wallet password, you need to use mnemonics or plaintext private key to import the wallet again, and use the new password to encrypt to generate a new keysore
9. CA first generates its own private key and public key, and the length of the key is generally 1024 bits.
10. It's not that you can't time out 2048, it's for the sake of safety and less computation. So we all default to 2048
