Ethereum Web3 auto charging

1. 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.

2. Don't go to ZT. It's dead. The coins on it will be off the shelves in less than a month. The platform allows you to go to the project side. Can only charge money can not reflect, garbage exchange

3.

The smart contract has been written for a long time

if they can add changes, the description is centralized

the contract is written into the Ethereum smart contract, which is a contradiction sentence

the financial customer service doesn't understand, which is very unreliable

4. How to run Ethereum source code go Ethereum
install MIPS based Linux header file
$CD $prjroot / kernel
$tar - xjvf linux-2.6.38. Tar. Bz2
$CD linux-2.6.38

create an include folder under the specified path to store related header files< br />$ mkdir -p $TARGET_ Prefix / include

ensures that the Linux source code is clean
$make mrproper

generates the required header file< br />$ make ARCH=mips headers_ check
$ make ARCH=mips INSTALL_ HDR_ PATH=dest headers_ Install

all the files in dest folder to the specified include folder< br />$ cp -rv dest/include/* $TARGET_ Prefix / include

delete dest folder at last
$RM - RF dest
$LS - L $target_ PREFIX/include

If you want to query the transaction records on the main network, you can use Etherscan. However, if you build your own private chain, how should you query the transaction records

the answer is that you need to listen to the logs on the chain, save them in the database, and then query them in the database. For example:

< pre t = "code" L = "Java" > varaddr = & quot& quot;< br />varfilter=web3.eth.filter({fromB lock:0 ,toBlock:' latest', address:addr });< br />filter.get(function(err,transactions){
transactions.forEach(function(tx){
vartxInfo=web3.eth.getTransaction(tx.transactionHash);
/ / at this time, the transaction information txinfo can be stored in the database
})< br />});

Web3. Eth. Filter() is used to monitor the log on the chain, and Web3. Eth. Gettransaction() is used to extract the information of the specified transaction. Once the transaction information is obtained, it can be stored in the database for query

expansion:

1. Ethereum is not an organization, but an underlying system that can realize intelligent contract and open source on the blockchain. From its birth to may 2017, Ethereum has more than 200 Ethereum applications around the world in just three and a half years. Ethereum is a platform and a programming language, which enables developers to build and release the next generation of distributed applications

Ethereum can be used to program, distribute, guarantee and trade anything: voting, domain names, financial exchanges, crowdfunding, corporate management, contracts and most of the agreements, intellectual property, and smart assets that benefit from hardware integration. On June 12, 2017, the price of Ethernet currency broke through $400, a record high. From $8 in February 2017 to $400 on June 15, 2017, the price of Ethernet currency has increased 50 times. At the same time, the price of bitcoin has eased, 10% lower than the previous peak, and the price of ether coin is much better; Take over & quot; Bitcoin continues to soar

7. This is a routine. Don't believe it can help you come up with it. Don't worry

8. The Internet has just begun, intelligent life coming

9. The best way to solve this problem is to stop charging money. We have stopped charging money. If we charge money, we can't charge money
