1. 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
2. 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
3. Shenzhen local words, it is recommended to consult Shengshi Huacai company, but also to the company specifically for your requirements.
4. Ethereum architecture consciousness is the 6-tier architecture of regional block chain. They are: data layer, network layer, consensus layer, incentive layer, contract layer and application layer. I personally feel that the best thing to do in Ethereum development is Shengshi Huacai, which is very professional
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 specifies the JSON RPC API application development interface that each node needs to implement. This interface is transport independent. Applications can use this interface protocol to operate Ethereum nodes through HTTP, websocket or IPC and other communication mechanisms:
8.
The
Ethereum mining
Berlin hard fork will mark the end of the metropolitan era. This is a key stage in Ethereum's history, which is divided into two stages (Byzantine and Constantinople), including several branches, including Atlantis, Istanbul, and finally reached its peak in Berlin
9. 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.
