 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

7. There are people using ethna. What are you going to do??? Do you need to work on projects? error: Class \&# 39; Ethna_ AppManager\&# 39; not found? ? The reason for the problem is that you don't find ethna in your PHP file_ Appmanager class. Your problem can be solved by using the name of the ethna add app object table?? Among the generated files, the file I generated is called LDL_ User. PHP, add this? require_ once(\& quot; ethna.php\& quot;); Can solve, but the premise is your PHP. INI file include_ Ethna & # 92 has been added to path&# 92; The absolute path of class. This path is the path Apache searches when include and require. In addition, I didn't succeed in connecting Oracle with pear:: dB, but I succeeded in connecting mysql. It seems that Oracle can't run because of the SQL statement automatically generated by ehtna. I'm looking for the reason! Good luck

8. The permissions are not enough. You are accessing the web. The web is executed as an Apache user. You need the root user to modify the IP.

9. No permission. PHP uses the user rights of Apache
generally, the permissions are very low, so you can only open and modify the files in the Apache Web folder. You can't call programs anywhere else
you use the login user's permission in Linux, which is also for security.
