摘要： A wall system with a height adjustment unit includes: a support frame which is installed on a floor surface; a lifting and lowering frame which is coupled to the support frame so as to be able to move up and down along the outer surface of the support frame while surrounding the support frame; and a plurality of height adjustment units which are installed between the support frame and the lifting and lowering frame so as to lift or lower the lifting and lowering frame. The height adjustment unit includes a support unit which is coupled to the inside of the support frame; and a height adjustment bolt screwed to the support unit and rotated by a tool to lift or lower the lifting and lowering frame, such that the lifting and lowering frame is horizontally adjustable and thus has increased constructability.

摘要： The present invention relates to a cryptocurrency trading brokerage server and a trading brokerage method in which records of trading digital tokens are encrypted and connected to node servers through a network having a block chain structure. A transaction between a first wallet client requesting to sell digital tokens and a second wallet client requesting to purchase digital tokens is matched to within a certain pre-set range of a basic ratio value to control price fluctuation. Also, a request from a fourth wallet client is received and an ownership certification key value matched to a personal key of the fourth wallet client is stored in a database of the trading brokerage server, thereby preventing a change of ownership due to hacking.
