Fig. 3 schematically illustrates a flow chart of a blockchain network-based funds release method in accordance with an embodiment of the present disclosure.
As shown in fig. 3, the blockchain network-based funds release method of this embodiment includes operations S301 to S303.
In operation S301, in response to the funds release request, funds release detailed information corresponding to the funds release request is uploaded to the supervising node so that the supervising node verifies the funds release detailed information according to the first information and the second information.
According to an embodiment of the present disclosure, the funds release request may include a funds release request actively issued by a user in order to request to obtain funds, but is not limited thereto, and may be actively issued by the management system upon reaching a preset funds release time.
According to embodiments of the present disclosure, the funds release detailed information may include a value of funds to be released, funds release information indicating a flow of funds, and funds release time.
According to the embodiment of the disclosure, the value to be issued may be verified first, for example, the value to be issued may be compared with a preset threshold interval, if the value to be issued belongs to the preset threshold interval, the value to be issued is confirmed to pass the verification, and if the value to be issued does not belong to the preset threshold interval, the value to be issued is confirmed to not pass the verification.
According to the embodiment of the disclosure, the preset threshold interval may be flexibly set by a person skilled in the art according to actual application situations, for example, by acquiring the historical funds release information, the highest value of the historical funds release and the lowest value of the historical funds release may be acquired, then the highest value of the historical funds release is taken as the maximum value of the preset threshold interval, and the lowest value of the historical funds release is taken as the lowest value of the preset threshold interval.
According to the embodiment of the disclosure, the funds receiver may be further verified, for example, the first funds receiver information corresponding to the funds release request may be obtained by analyzing the funds release information indicating the flow direction of the funds in the funds release detailed information, and since all nodes in the blockchain store the second information of all funds receivers and the second information includes the first information of the funds dispenser corresponding to the funds receiver, after the first information of the funds receiver is obtained, the second information of the first information of the funds receiver is obtained, so as to determine the first funds dispenser corresponding to the first funds receiver, and then the first funds dispenser is matched with the funds dispenser in the funds release information, if the first funds dispenser is successfully matched with the funds dispenser in the funds release information, it may be determined that the funds receiver passes the verification.
According to an embodiment of the present disclosure, the supervisory node may be determined by determining the number of blocks that have been found in the blockchain, determining the number of consensus nodes included in the blockchain system, determining a remainder result obtained by dividing the number of blocks that have been found by the number of consensus nodes, and determining a target consensus node number, wherein the target consensus node number is a consensus node number equal to the remainder result, and determining a consensus node corresponding to the target consensus node number as the supervisory node.
According to the embodiment of the disclosure, the supervision node is not fixed and can be reelected according to actual conditions. I.e. if the supervision point fulfils the re-election condition, a re-election operation may be performed. Wherein the re-election condition may include whether the blocking request is terminated within a preset period of time. The re-election condition may be indicated as being satisfied if the blocking request is terminated within a preset period of time, and may be indicated as being not being satisfied if the blocking request is not terminated within the preset period of time. Wherein the blocking request may be terminated due to a failure of the supervising node itself and/or a disruption of the communication connection between the supervising node and other consensus nodes.
In operation S302, after the monitoring node verifies the detailed information of funds release, the plurality of consensus nodes perform consensus processing on the detailed information of funds release 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 detailed information of the funds release is not passed, the request for the funds release can be refused.
According to embodiments of the present disclosure, the structures of all consensus nodes may be identical, and the consensus nodes are used to perform validity verification on a transaction, where the validity verification may include, but is not limited to, authority verification, parameter verification, and the like.
In operation S303, in case the consensus result satisfies the consensus condition, funds release detailed information is recorded in the blockchain.
According to embodiments of the present disclosure, after the consensus result satisfies the consensus condition, each consensus node may package the funds release details into blocks and then connect the generated blocks with the end of the existing blockchain.
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 blockchain network, and the detailed fund issuing information meeting the consensus condition is recorded on the blockchain, so that the defect of distributed storage (data is synchronized by backing up nodes to other nodes through a central node) in the related art can be overcome, and the safety of the data is ensured.
According to an embodiment of the present disclosure, the preset consensus mechanism includes at least one of:
a Proof of Work mechanism (PoW), an authorized equity Proof mechanism (Delegated Proof of Stake, DPOS), a equity Proof of authority mechanism (PoS), a importance Proof mechanism (Proof of Importance, POI), a utility barthology mechanism (Practical Byzantine Fault Tolerance, PBFT).
According to embodiments of the present disclosure, the consensus mechanism may be a PBFT algorithm. The PBFT algorithm includes three stages of preparation (pre-preparation), preparation (preparation), and validation (commit). The three phases are sequentially executed, and each consensus node can perform the next phase after receiving the acknowledgement messages sent by the preset number of consensus nodes in each phase. And each consensus node in all the consensus nodes performs consensus processing on the funds release detailed information by using a PBFT algorithm.
