1. 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)
2. If this is only the most basic, it can be done by 100000 yuan. If you need to add other functions, it depends on the difficulty of the functions you add. If you want affordable price and good service, I suggest you consult Shengshi Huacai company. I've used it for two years, and almost no problems have occurred.
3. Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency Ethereum. If you need to, you can contact Shengshi Huacai. They do it very well
4. Yes, Shengshi Huacai has done a good job. Ethereum is an open source public blockchain platform with intelligent contract function. It provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency, Ethereum. Shengshi Huacai has done a good job in this area, which is worth recommending
5. Shengshi Huacai company has done a good job in the development of Ethereum.
6. My computer - & gt; Attribute - & gt; Advanced - & gt; Environment variables - & gt; Add the following environment variables to the system variables:
java_ The home value is: the directory where JDK is installed, and mine is C: &# 92; Program Files\ Java\ jdk1.6.0_ 34
the classpath value is:;% JAVA_ HOME%\ lib\ tools.jar;% JAVA_ HOME%\ lib\ dt.jar;% JAVA_ HOME%\ bin;( Pay attention to the & quot& quot; To add)
Path: append at the beginning.;% JAVA_ HOME%\ bin;% JAVA_ HOME%\ jre\ bin;( Pay attention to the & quot& quot; To add)
after the installation, you can check whether the JDK is installed successfully. Open the CMD window and enter Java – version to view the version information of JDK.

7. Ethereum is a virtual currency. Ethereum and bitcoin have similar properties.
8. Link aggregation. Different types of switches support different numbers. You can enter
interface eth trunk? On the switch? It will prompt you with a numerical range
this numerical range is the number of supports. But are you sure you have so many ports to use
for example, you can use two ports for one aggregation. 24 port switching supports 12 aggregations at most< Moreover, link aggregation is the connection between switches. Generally, one uplink and one downlink are enough. Unless you're a core exchange or something special.
