Abstract: 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.
