Instant messaging method based on block chain

Abstract

The invention provides an instant messaging method based on a block chain, and the method comprises the steps: a user registers at a management node for subsequent communication, a sending user generates communication information, and sends the communication information to the management node, the management node obtains an identifier of a receiving user, judges whether the receiving user is a registered user or not according to the identifier of the receiving user, if the user is not the registered user, stopping the operation, if the user is the registered user, it is judged whether the instant messaging application of the sending user and the instant messaging application of the receiving user are the same or not, if yes, the communication information is encrypted, and the communication information is sent to the receiving user through the domain instant messaging server; and if not, the communication information is sent to the receiving user through the domain instant communication server of the receiving user, and the receiving user decrypts the encrypted communication information. According to the instant messaging method based on the block chain, the problem that personal information of a user is leaked due to a traditional instant messaging method can be solved, and interaction between different instant messaging applications can be achieved.
