Ethereum hidden balance

1. Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of tens of thousands of computers around the world.

2. There are two possibilities. One is that the platform didn't give you a coin, so you need to consult customer service. The second kind of wallet problem has not been reflected by you. I mentioned this situation on ZB platform before. The customer service of the platform said there was a problem with the wallet, and then returned it to me. The original account was pulled.

3. This needs to be recharged, but we must pay attention to the risk. This chain is not particularly mainstream. It may be the capital disk or counterfeit currency.

4. 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

5.

in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety

take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:

1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.

firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required

then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers

Second, the bank system verifies the financial level motherboard and encryption chip

uses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area

Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fast

the reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency

Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank you

6. Return the result of ifconfig
eth0 to awk for processing
where - F & # 39;:|< br />+'
this is a separator defined by awk and then matched with "BCAST & quot;, Take the content of the fourth column
since your command is not universal, you can't output the result here, but you should intercept the broadcast address

7. If the recharge amount is less than the minimum amount, it can be added to the account cumulatively. Please note:
1. There is no limit on the recharge time and currency, that is, no matter when the user recharges the currency, it can be entered into the account when the cumulative amount reaches the minimum recharge amount
2. The cumulative entry of the recharge amount is the normal success of the recharge, not our artificial system operation. Both the background and the foreground will display user recharge records. For example, for example, recharge usdt, and the minimum is 100usdt. Now the user has charged 97, our function is online, and the user has charged 10 more. Both the background and the foreground will display 97 and 9.5. Two records
3. Users who have recharged many times before are less than the minimum amount. Now they have reached the minimum amount, which can also be recorded. There is no need for users to recharge again
4. Without recording user information, users can recharge the currency by themselves to reach the minimum amount of recharge, complete the block confirmation, and then display it in their hot currency account
5. If the cumulative amount of user recharge is greater than the minimum amount, you can enter it into the account, that is, if the user previously recharged 20 usdts, and now recharged 200, then 220 will be entered into the account

8. It's good-looking. The plot and special effects are very good. It's the first sink auditorium in China. It's very shocking
