Ethereum three

1. Ethereum is a new and open blockchain platform, which allows anyone to build and use decentralized applications running through blockchain technology in the platform
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.

2.

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

3. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)

4. Pyramid selling refers to: in the name of selling or promoting goods, the popular point is to attract people to join the association through temptation and collect membership fees as the main way of making profits, that is, pyramid selling (without any physical goods and investment procts in essence)
Direct Selling: a sales system built by a group or enterprise, which develops the first, second, third, provincial, municipal, and local level businesses with indivials or teams County level and other regional agents, physical settlement, according to their agency level to obtain unequal proportion of commission,

5. For indivial investors, the realm kingdom with lower investment threshold is more suitable, because its entry threshold starts from $100, which is very low.

6. At present, it's 4000 RMB / an ether coin. You can check the specific price on celletf

7. After the hard bifurcation of etc, ETH came into being. The relationship between the three currencies is just like that between yen, won and US dollar

8. How many account addresses can an Ethereum node have at most
A: generally, there is only one account address, otherwise there will be an error! Blockchain itself is unique. If there are multiple account addresses on one node, it violates the fundamental principle of blockchain!

9.

The postcode of Hefei city is 230000

the new administrative and cultural zone of Hefei is located in the southwest of the main urban area of Hefei, the provincial capital, with Jinzhai Road Viact in the East, Hefei high tech Instrial Development Zone in the West and Hefei Economic and Technological Development Zone in the south. With a planning area of 12.67 square kilometers, it is an important part of the main urban area in Hefei's "141" urban space development strategy. It is also a new political and economic center and commercial and cultural center of Hefei, the provincial capital, integrating the functions of administrative office, culture, ecation and sports, Finance and trade, tourism and vacation, residence and leisure

The common information of Hefei administrative district is as follows:

1. Area: About 6km southwest of the old city center

2. Area code: (+ 86) 0551

3. Administrative division code: 340100

4. License plate code: Wan a

extended information:

located in the main direction and heart of Hefei urban development sector, the new administrative and cultural zone is the only way to connect the main urban area, economic and Technological Development zone and university town. It is 20 minutes' drive from Hefei railway station, close to Hefei West Railway Station, and adjacent to Hefei Nanjing, Hefei Xuzhou, Hefei Wuhu expressways, It's only 10 minutes' drive from Hefei Luogang airport, and the airport and station are within the "living circle" of 20 minutes. It is not only the throat of the main urban area's westward and southward expansion, but also a beautiful window to reflect the image of modern Hefei City in the demonstration area of Wanjiang city belt's undertaking instrial transfer

China's postal code adopts a four level six digit structure. The first two digits indicate the province (municipality directly under the central government or autonomous region); The first three digits indicate the postal area; The first four digits represent counties (cities); The last two digits indicate the delivery office. Postcode is to realize the implementation of automatic mail sorting scheme, because the computer can not recognize Chinese, but can recognize numbers. Code each area, can quickly use the computer sorting, to write the more detailed the better
