How much data does Ethereum have

3.

Ethereum 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

Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")

The token on the

blockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum

the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin

extended data:

Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks

for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound

in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale

5. According to the data of spider mine pool:
BTC full network computing power 153.280eh/s, mining difficulty 21.72t, current block height 672055, theoretical income 0.00000690/t/day
the total network computing power of eth is 418.403th/s, the mining difficulty is 5380.94t, the current block height is 11923460, and the theoretical profit is 0.00709464/100mh/day
BSV network computing power is 0.544eh/s, mining difficulty is 0.08t, current block height is 675889, and theoretical income is 0.0081/t/day
BCH's whole network computing power is 1.596eh/s, mining difficulty is 0.20, the current block height is 676209, and the theoretical profit is 0.00056395/t/day<

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.

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

Compared with bitcoin's prestige, although the rise of the value of ether currency is more terrible than that at the beginning of the year, its reputation and market scale are still inferior to bitcoin. Peter szilagyi, director of bitcoin development team, brought the data of Ethernet network nodes to Google Earth to tell you clearly how Ethernet will dominate the digital currency world in the future

in the two years since its birth, Ethereum has rapidly occupied the rich countries or regions in the world

if we compare the richer regions in the world, such as Europe and North America, with the poorer regions in Asia and South America, & quot; In an email interview with CNBC, szilagyi wrote: & lt; You will find that the density of active nodes is related to the transportation convenience, instrialization and affluence of the region. In my opinion, this correlation is e to the relatively concentrated resources required for the full operation of Ethereum& rdquo;

8. The biggest disadvantage of Ethereum is that its quantity has been increasing. How can an item without an upper limit be used as an investment proct? As we all know, the rise in the price of a commodity is in the final analysis the quantity comparison between the supply and demand sides. The supply exceeds the demand, the price falls, the supply is less than the demand, and the price rises. The amount of bitcoin and lettercoin is fixed. The total amount of bitcoin is 21 million, and now there are more than 10 million. The rest will take another 100 years. Now the amount of Ethereum is more than 90 million, and 18 million will be generated every year. Ethereum has 250 blocks per hour, 5 coins for each block (and some transaction fees and other rewards), 24 hours a day, that is, 30000 + coins will be added every day. So there's no limit to the amount of ether

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.
