precautions:
1. The co founders of Ethereum believe that competition will be positive, and the world absolutely needs to see that indivial freedom is respected, and that they can freely access global IT tools. The data of these tools are not controlled by companies or companies that can use digital transformation to increase data
Unlike paper or pound gold, code lines allow people to transfer value digitally. However, the difference between them and traditional currency lies in the source, maker and owner. These new currencies, designed by computer scientists and based on Mathematics and cryptography, are not forged, controlled or supported by the governmentEthereum is the next generation of cryptography ledger. It intends to support many advanced functions, including user issuing currency, intelligent protocol, decentralized transaction and what we think is the first fully decentralized autonomous organization (Daos) or decentralized autonomous company (DACS) application
Ethereum does not specifically support every single type of function as a feature. On the contrary, Ethereum includes a built-in Turing complete scripting language, which allows you to write code for the feature you want to implement through a mechanism called "contract". A contract is like an automatic agent. Every time a transaction is received, the contract will run a specific code, which can modify the data storage inside the contract or send the transaction. Advanced contracts can even modify their own code
Ethereum was launched on November 1, 2015, and launched on August 22, 2016 on bitcoin trading platform, a well-known domestic trading platform; 30-¥ About 60, current: ¥ 1259.97, the rise is amazing

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 />}); Pre >
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

how many years can the ether coin be g
how many Ethernet coins can be proced each year? At present, five new ether coins are generated for each new block. If you dig out a block every 14 seconds, it will take 31.5 million seconds (365 x 24 x 60 x 60) a year, which means that 2.25 million blocks are g out every year
every miner has considered how long the ether coin can be g, whether I can't dig the ether coin after I buy the miner, or I can't dig the ether coin after I invest in the miner. I can tell you clearly that the ether coin can't be g up, and the official shows the quantity when it comes to the ether coin, but don't go, Ethernet currency is constantly bifurcating. Once the quantity is threatened, it will continue to bifurcate. The miners can continue to dig for new currencies from the bifurcations. For example, etc and ETF are examples. After the bifurcations, the ETH price will go up crazily. Therefore, miners need not worry about the quantity of Ethernet currency.
