1. Ethereum is a very famous fire coin in virtual currency. It is based on smart contract and covers a wide range. It is a very good investment. The current price is $160, and the best time is about $10000. You can query it on okex and other platforms
2. What does the number of people in the Ethereum contract mean? I know the top speed.
3. 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
4. Gas & gt; ethestimateGas({ from:ethaccounts [1], to: ethaccounts[2], value:50000000000000 }) 21001 > Ethgasprice 2000000000, as shown above, shows this account [1] = & gt; The transaction of account [2] needs 21001 gas, and the current gasprice is 2000000000. How many gas does it take to send transaction / call contract method in Ethereum
5. As long as you can pay the deposit, choose the right direction.
6.
Generally speaking, the steps of deploying smart contract are as follows:
- start an Ethereum node (such as geth or testrpc)
- use Solc to compile smart contracts=& gt; Get the binary code
- deploy the compiled contract to the network This step will consume Ethernet currency, and you need to use the default address or specified address of your node to sign the contract.)=& gt; Get the blockchain address and ABI of the contract (JSON representation of the contract interface, including variables, events and callable methods) The author confused ABI with contract interface here. ABI is the binary representation of the contract interface.)
- use the JavaScript API provided by web3.js to call the contract Depending on the type of call, it may consume Ethernet currency.)
7. 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

8. 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.
9. You can choose by yourself, and the minimum gas quantity is different for different contracts. General minimum 6000gas
10. 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
