1. Because blockchain technology has natural advantages in realizing smart contracts. bitcoin, Ruitai, Laite, Ethereum and other digital cryptocurrencies all use blockchain technology. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a chain of uses
2. The service charge of different exchanges is different, fire currency and okex are 0.02% 0.03% and Qube are 0.01%.
3. First of all, what ADA does is the concept of smart contract. I think you should be familiar with smart contract, but for some new people, I still want to explain. The so-called smart contract is to write a contract that the computer can understand through the programming language, because there is no need for a third party, and the executor of the contract is a selfless computer, so it solves the problem of trust between people. For details, please refer to GitHub smart contract
Ethereum is a blockchain smart contract. Now Ethereum ranks 2-3 in the market value ranking, with a market value of 25% of bitcoin. However, Ethereum also has some problems, such as slow trading, high fuel costs and the mining mechanism that has been criticized repeatedly. Familiar? All of bitcoin's problems are with Ethereum. Some time ago, the Ethereum cloud cat game developed on Ethereum went online in the first week, directly blocking Ethereum's trading network. I tried to pay a high gas fee of nearly 100 yuan, but I still couldn't transfer it successfully. This can't help but lower my expectation of Ethereum. Ethereum is a great idea of V God, but after all, it is a pioneer, and there is a long way to go from perfection.

4. 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

5. Last time, I cooperated with Shengshi Huacai company in Shenzhen. Shengshi Huacai company knows a lot about the development of blockchain system, and many companies are looking for them to do blockchain system.
6. You can choose by yourself, and the minimum gas quantity is different for different contracts. General minimum 6000gas
7.
Gas is translated as "gasoline cost". Gas was originally implemented on the Ethereum blockchain to measure the computing and storage resources consumed by messages
in other blockchains, node participants specify gasfee in local currency, and then pay priority fees to the proction node participants' blocks according to the natural gas consumed by the message
In fact, gas is similar to gasoline, which is used as the energy of a car to ensure that the car can run normally. Gas on Ethereum network "refuels" the transaction behavior and allows users to perform different operations
{rrrrrrr}
the reason for the existence of gas. Gas fee will be priced from high to low. Messages with low price may not be packaged, while messages with high price will be packaged first, so gas fee is a market behavior
when the news is congested, the cost of gas will rise. If we do not deal with the congested news in time, we will lose the computing power. If the computing power does not recover for two consecutive days, we will be severely punished
if there is no gas, users can execute a program that will never stop. The reason may be that there is a problem with the code, or someone does evil. In order to prevent this situation, Ethereum introces the gas cost associated with each operation, which will prevent the program from running forever, and finally make the whole network stagnate
8. You can choose to buy Ethereum from the common exchanges in the market, such as fire coin, coin an, and okex. The minimum purchase amount of fire coin is 100 yuan, and the first week of spiderdex online is free of service charge, so you only need to pay a small amount of gas fee, about a few cents.
9. In a public chain, anyone can read and write data. Reading data is free, but writing data to the public chain costs a certain amount of money, which helps to prevent junk content and protect its security through payment. Any node on the network (each connected device containing a of the ledger is called a node) can participate in a way called mining to protect the network. As mining requires computing power and electricity charges, miners need to be paid for their services, which is also the origin of miners' fees
miners will give priority to the deals with reasonable gas and high gas price. If the miner's fee paid by the user is very low (out of gas), the transaction may not be packaged by the miner, resulting in the failure of the transaction. The transaction cost of tokenpocket (also the transaction cost of Ethereum) = gas quantity * gas price
gas is the unit used to measure the calculation workload required to perform specific operations on the Ethereum blockchain. The name itself was not chosen by accident. Gas is actually similar to gasoline, which is used as the energy of a car to ensure that the car can run normally. Gas on Ethereum network "refuels" the transaction behavior and allows users to perform different operations
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
