1. An electronic device comprising:
a communication circuit configured to communicate;
at least one processor operatively connected to the communication circuit; and
a memory operatively connected to the at least one processor,
wherein the memory stores instructions that, when executed, cause the at least one processor to:
request a push server to generate a push key,
transmit, to a management server, a request to encrypt the push key received from the push server, using the communication circuit,
in response to the request, receive the encrypted push key from the management server,
generate at least one transaction based on the encrypted push key, the at least one transaction comprising data associated with requesting a push service registration to a blockchain network,
transmit the at least one transaction to a blockchain network to record the encrypted push key in at least one block of the blockchain network, and
in response to a push event occurrence based on a smart contract, receive a push message associated with the push event from the management server via the push server based on the encrypted push key recorded in the at least one block.
