Abstract: An electronic device is provided. The electronic device includes a communication circuit, memory storing one or more computer programs, and one or more processors communicatively coupled to the communication circuit and the memory. The one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the electronic device to transmit a request, through the communication circuit a server configured to relay message transmission between nodes included in a blockchain network, to add a new block to the nodes included in the blockchain network, when the request is not rejected by the server, transmit, through the communication circuit to the server for transmission to the nodes via the server, transaction information to be stored in the new block, generate the new block including the transaction information, receive, through the communication circuit from the server, information about blocks generated by first nodes in an active state among the nodes, based on identifying that a number of blocks identical to the new block among the blocks generated by the first nodes is greater than a designated number, transmit, through the communication circuit to the server, information indicating agreement on adding the new block, and based on the transmitting, to the server, of the information indicating the agreement, add the new block to the memory.
