An instant messaging system based on blockchain includes: a central node and at least two domain instant messaging servers. The central node includes a management node and a blockchain node. Information about a user is stored in the blockchain node. The at least two domain instant messaging servers correspond to at least two instant messaging applications, respectively. A method for implementing the instant messaging system is implemented at the central node, and includes performing, in response to a request from the domain instant messaging server, a corresponding operation or providing corresponding information about a user to the domain instant messaging server. The central node establishes a communication connection with a plurality of domain instant messaging servers, such that each domain instant messaging server can send respectively data to the central node to realize a data sharing, and an interaction between different domain instant messaging servers.

Embodiments of the present invention provide a method for questioning and answering. For example, the method may comprise: receiving a message input by a user; sending the message to a question-and-answer server such that the question-and-answer server sends the message to one or more answerer clients; in response to users of the answerer clients performing a real time reply operation for the message, entering into a real time session with the users of the answerer clients so as to obtain a reply message from the users of the answerer clients through the real time session. With the present invention, a questioner and an answerer may send and receive messages through clients dedicated for questioning and answering, and both parties may enter into a one-to-one or one-to-many real time session when the answerer replies in real time, therefore better immediacy and better user experience may be achieved. In addition, embodiments of the present invention provide a device for questioning and answering.
