The site server receives the lottery ticket purchase request from the terminal equipment and then verifies the first signature information in the lottery ticket purchase request according to the first public key. After the first signature information passes the verification, the site server signs the lottery information, the user identity information and the site identification of the site server according to the private key of the site to obtain second signature information, and then transaction information is generated according to the lottery information, the user identity information, the first signature information, the site identification and the second signature information. Transaction information is then written to the blockchain network.
And after the block chain network finishes the writing of the transaction information, returning a processing result to the site server.
And the site server receives the processing result returned by the blockchain network and feeds back a successful purchase message to the terminal equipment.
The user can inquire the related information of the lottery purchased by the user in the block chain network through the terminal equipment. When the lottery purchased by the user wins, the terminal equipment signs the lottery information and the user identity information according to the private key of the user to obtain third signature information. And then generating a lottery ticket exchange request according to the lottery ticket information, the user identity information and the third signature information, and sending the lottery ticket exchange request to the exchange center server.
The exchange center server receives a lottery ticket exchange request from the terminal equipment. And then, after inquiring in the block chain network, finding that the exchange information corresponding to the lottery exchange request does not exist, and finding out the transaction information corresponding to the winning lottery information in the block chain network. Then, the user identity information in the transaction information, namely the identity information of the winner, is obtained by analyzing the transaction information. And searching the public key of the winning user from a database storing the public key of the user according to the identity information of the winning person, thereby obtaining a third public key. And decrypting the third signature information according to the third public key to obtain lottery information and user identity information, and comparing the lottery information and the user identity information obtained by decryption with the lottery information and the user identity information in the lottery exchange request. If the two are consistent, the lottery information of the winning lottery and the identity information of the winner are generated to exchange information, and the exchange information is written into the block chain.
And after the block chain network finishes writing the exchange information, returning a processing result to the exchange center server.
And after receiving the processing result returned by the block chain network, the exchange center server issues the bonus to the account of the bonus exchange user.
