Fig. 3 schematically illustrates a flow chart of a method for funds release based on a blockchain network according to an embodiment of the present disclosure.
As shown in fig. 3, the method for funds release based on the blockchain network according to the embodiment includes operations S301 to S303.
In operation S301, in response to the fund release request, the fund release detailed information corresponding to the fund release request is uploaded to the supervising node, so that the supervising node verifies the fund release detailed information according to the first information and the second information.
According to embodiments of the present disclosure, the funds release request may include, but is not limited to, a funds release request actively issued by the user to request to obtain funds, and may also be an funds release request actively issued by the management system when a preset funds release time is reached.
According to an embodiment of the present disclosure, the funds release detailed information may include the value of funds to be released, funds release information indicating the flow of funds, and funds release time, among other information.
According to the embodiment of the disclosure, the fund value to be issued may be verified first, for example, the fund value to be issued may be compared with a preset threshold interval, if the fund value to be issued belongs to the preset threshold interval, it is determined that the fund value to be issued passes the verification, and if the fund value to be issued does not belong to the preset threshold interval, it is determined that the fund value to be issued does not pass the verification.
According to the embodiment of the present disclosure, the preset threshold interval may be flexibly set by a person skilled in the art according to practical application conditions, for example, the highest value of the historical fund release and the lowest value of the historical fund release may be obtained by obtaining the historical fund release information, and then the highest value of the historical fund release is used as the maximum value of the preset threshold interval, and the lowest value of the historical fund release is used as the lowest value of the preset threshold interval.
According to the embodiment of the disclosure, the fund receiver can be also verified, for example, the first fund receiver information corresponding to the fund release request can be obtained by analyzing the fund release information used for indicating the fund flow direction in the fund release detailed information, since all the nodes in the blockchain store the second information of all the fund receivers, and the second information comprises the first information of the fund issuer corresponding to the fund receiver, thereby acquiring second information of the first money receiver information after acquiring the first money receiver information, thereby determining a first money issuer corresponding to the first money receiver, and then matching the first fund issuer with the fund issuer in the fund issuing information, and if the matching of the first fund issuer and the fund issuer in the fund issuing information is successful, determining that the fund receiver passes the verification.
According to the embodiment of the disclosure, the supervision node may be determined by determining the number of blocks of the block chain, determining the number of common identification nodes included in the block chain system, determining a remainder result obtained by dividing the number of blocks by the number of common identification nodes, and determining a target common identification node number, where the target common identification node number is a common identification node number equal to the remainder result, and determining the common identification node corresponding to the target common identification node number as the supervision node.
According to the embodiment of the disclosure, the supervision node is not fixed and can be reselected according to the actual situation. I.e. if the supervision point fulfils the re-election condition, a re-election operation can be performed. Wherein the re-election condition may include whether the blocking request is terminated within a preset time period. The re-election condition may be declared satisfied if the blocking request is terminated within a preset time period, and may be declared unsatisfied if the blocking request is not terminated within the preset time period. The reason for the blocking request being terminated may be, among other things, a failure of the supervising node itself and/or a disruption of the communication connection between the supervising node and the other cognizant nodes.
In operation S302, after the supervision node verifies the fund issuance detail information, the multiple consensus nodes perform consensus on the fund issuance detail information based on a preset consensus mechanism, and generate a consensus result.
According to the embodiment of the disclosure, if the verification result of the supervision node for verifying the fund release detailed information is failed, the fund release request can be rejected.
According to the embodiment of the disclosure, all the consensus nodes may have the same structure, and the consensus nodes are used for performing validity verification on the transaction, and the validity verification may include, but is not limited to, authority verification, parameter verification and the like.
In operation S303, in case that the result of the consensus satisfies the consensus condition, the fund issuance detail information is recorded in the blockchain.
According to the embodiment of the disclosure, after the consensus result meets the consensus condition, each consensus node may pack the fund release detailed information into a block, and then connect the generated block with the end of the existing block chain.
In the embodiment of the disclosure, the first information of the fund issuer and the second information of the fund receiver are stored on all nodes in the block chain network, and the fund issuance detailed information meeting the consensus condition is recorded on the block chain, so that the disadvantage of distributed storage (data synchronization to other nodes through a central node) in the related art can be eliminated, and the data security is ensured.
According to an embodiment of the present disclosure, the preset consensus mechanism comprises at least one of:
a workload certification mechanism (Proof of Work, PoW), an authorized equity certification mechanism (DPOS), a stock authorization certification mechanism (Proof of Stack, PoS), an Importance certification mechanism (Proof of Importance, POI), and a Practical Byzantine (PBFT).
According to embodiments of the present disclosure, the consensus mechanism may be a PBFT algorithm. The PBFT algorithm includes three stages of pre-preparation (pre-prepare), preparation (prepare), and validation (commit). The three stages are sequentially executed, and in each stage, after each consensus node receives the confirmation messages sent by the preset number of consensus nodes, the next stage can be performed. And each of all the consensus nodes performs consensus processing on the fund release detailed information by utilizing a PBFT algorithm.
