Ethereum data trends
just like bitcoin, Ethereum is neither controlled nor owned by anyone - it is an open source project created by many people around the world. Different from bitcoin protocol, Ethereum's design is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform. With the release of homestead, anyone can use the applications on this platform safely
Ethereum is a programmable blockchain. It does not give users a series of preset operations, but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator.
DTV share, Ethereum is an open source public blockchain platform with intelligent contract function. It provides decentralized virtual machines to handle point-to-point contracts through its private cryptocurrency, Ethernet. Key points: open source, smart contract function, public chain platform, Ethernet
however, bitcoin is not the only cryptocurrency with rising value. The value of another cryptocurrency called Ethereum has been increasing since January 2017. From $8.24 to $203. Up 2367%
investors are worried that in the past few years, cryptocurrencies have gained the favor of many investors who are looking for other investment methods than traditional ones. Although most investors still invest their money in traditional financial markets, such as the stock market and foreign exchange market, many of these investors have begun to worry about the economic climate of the world economy
recent events have made us aware of the instability of traditional financial markets such as the stock market and foreign exchange market. Many investors have been looking for other ways to invest their money
with the creation and popularization of cryptocurrency and its rapidly rising value, many investors, especially those from Asia, have joined the trend of bitcoin and cryptocurrency
advantages of Ethereum
although many people are more familiar with it, Ethereum has also gained a fair share of the market with its own value. However, there are key differences between the blockchains used by Ethereum and bitcoin
the difference between the two systems is that Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
although many people may think that Ethereum may be inferior to bitcoin because its value is lower than bitcoin, this is a good thing for investors who are looking for investment channels other than bitcoin. A lower price may attract more investors because it has more room for growth. The only drawback is that Ethereum is not as established as bitcoin. In view of this, bitcoin is more secure than Ethereum<
not as volatile as before
since bitcoin was founded in 2009, cryptocurrencies have made great achievements, and they have continued to grow. In fact, the value of legal cryptocurrency has risen a lot since then
although cryptocurrencies have performed very well this year, analysts expect that when the economic situation is good, investors will leave cryptocurrencies and return to traditional investment media. When this happens, the volatility of cryptocurrency will decrease because of the decrease of demand
of course, we will still see the growth of cryptocurrency in the next few years, which will help the instry remain strong. When that happens, it's a good idea for investors to hold cryptocurrencies for future growth.
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 theblockchain 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
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;
