Fig. 1 is a kind of flow diagram for business account register method based on block chain that the embodiment of the present disclosure provides, Include the following steps:
S100: target user's node receives account register instruction.
In the embodiments of the present disclosure, block chain network is generally based on publicly-owned chain framework (such as ether mill) builds.It is any User can be by installing block chain program (such as ether mill wallet program) on the equipment of oneself (such as computer, mobile phone) and opening Lead to the block chain account of oneself, and becomes a user node in block chain network.That is, user node is specifically to use The equipment at family+block chain program+user block chain account, a user node represent a user.
In block chain network, each user node has unique corresponding block chain account, in block chain account Surplus (under the framework of ether mill, the remaining sum in block chain account specifically can be ether coin remaining sum).It needs to illustrate herein It is that the block chain account of user is usually controlled by the private key of user, and the private key of oneself is supplied on user node and installs by user Block chain program, the block chain account of oneself can be just logined, at this point, user just achieves the control to user node.
For each user node, intelligent contract can be deployed on the user node.Intelligent contract is substantially one section For realizing the code of specified logic, user node calls intelligent contract, so that it may realize specified logic.
In business account register method shown in Fig. 1, the intelligent contract disposed on each user node can be used for holding Row account warrant interrelated logic.The account warrant interrelated logic may include the generation logic of account warrant, be account warrant The logic of distribution warrant mark establishes warrant mark and the logic of corresponding relationship of account identification etc..
In the step s 100, target user's node can be any user node in the block chain network.Institute Stating account register instruction can be the sending of target user representated by target user's node.The intention of the account register instruction It is that instruction block chain network generates account warrant, the account warrant of generation is distributed to the block chain account of target user, so as to Service server under chain registers business account according to account warrant, and completes the binding of account warrant Yu business account.
It should be noted that the block chain program that target user usually requires to install on target user's node provides oneself Private key after, the control to target user's node could be obtained, at this point, target user's node could represent target user, mesh Instruction could be sent (for example, the block chain journey that target user installs on target user's node to target user's node by marking user Instruction is inputted in sequence).
That is, after the private key of oneself is supplied to the block chain program installed on target user's node by target user, The target block chain account of oneself is logined.At this point, target user, target user's node, target block chain account are substantial It is integrated.
S102: target user's node constructs account registration message according to the account register instruction, and by described The corresponding target block chain account of target user's node, signs to the account registration message.
It is well known that message is data structure used by communicating in block chain network.In step s 102, the account Registration message may include the account identification of the corresponding target block chain account of target user's node.The destination node is logical The target block chain account is crossed to sign (to show the account registration message by target to the account registration message User's authorization), it specifically can be the destination node using the private key for controlling the target block chain account, the account infused The abstract of volume message is encrypted, and the corresponding signature of the account registration message is obtained.
S104: target user's node broadcasts the account registration message to the block chain network.
In step S104, target user's node can be by the Account Registration message and the account registration message Corresponding signature is broadcasted together to block chain network.
S106: for each user node for obtaining the account registration message, which is determining the account After registration message passes through signature verification, the intelligent contract based on deployment generates account warrant, and establishes the power of the account warrant Corresponding relationship between card mark and the account identification.
