Detailed Description
Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.
Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).
In the related art, the circulation of data processing involving multiple parties is mostly realized based on flow engines such as Activiti, Flowable, camunda and the like. The concrete implementation mode adopted comprises the following steps: and (3) establishing a centralized flow control center by using a flow engine, formulating a flow definition file, and then controlling the flow of data processing steps among a plurality of participants by the flow control center.
A single-point problem exists in the process of adopting a process engine to build a process control center to control the data processing flow among multiple participants. For example, due to technical limitations, hardware devices have a greater possibility of failure in the whole life cycle, and when a failure occurs in the process control center, the whole data processing flow framework is not usable; for another example, because the process definition file is usually stored in the process control center, if a certain service participant issues or modifies the process definition file on one side without notifying other service participants, the normal operation of the service process may be affected; or, all the flow scheduling information is stored in the flow control center, so that the data is not credible; for another example, when a plurality of service participants perform data processing circulation, the service participants need to remotely interact with the process control center, which may cause a large delay and errors that may be caused by network transmission.
In view of this, the embodiments of the present disclosure implement distributed deployment of a framework based on a distributed node mechanism of a blockchain network, and a centralized flow control center node is not needed any more, so as to implement a decentralized purpose. Specifically, embodiments of the present disclosure provide a data processing method, an apparatus, an electronic device, a readable storage medium, and a computer program product implemented based on a blockchain system. The block chain system comprises a plurality of block chain nodes, and the block chain nodes are configured with a first block chain ledger book, a first intelligent contract and a second intelligent contract, and the method comprises the following steps: for each block chain node in the block chain system, responding to a trigger timing task, calling a first intelligent contract to query a first block chain account book to obtain at least one first block associated with the block chain node; under the condition that a first target block exists in at least one first block, analyzing and processing the first target block to obtain target data; and calling the second intelligent contract to perform circulation processing on the target data.

For example, the flow order of the service a may be set to be sequentially performed by the block link points a, b, and c. For another example, the flow sequence of the service B may be set to be executed by the blockchain node a first, and then executed by the blockchain nodes B and c in parallel.

According to an embodiment of the present disclosure, a second chunk may be generated by packaging the target data, and then the second chunk may be written into the child chain in the first blockchain ledger that corresponds to the first target blockchain link point. Alternatively, the identification information associated with the link point of the first target block may be added to the second block, and then the second block to which the identification information is added is written into the first block chain account.
According to an embodiment of the present disclosure, operation S302 may include the operations of:
acquiring at least one third block associated with the service identifier from the second block chain account book; determining a second target block from the at least one third block; and analyzing the second target block to obtain a first flow definition file.

The preset ratio may be 80%, 90%, etc., and may be set according to a specific application scenario, which is not limited herein.
According to the embodiment of the present disclosure, in a case that the first common identification proposal does not achieve common identification, feedback information that the common identification is not achieved may be sent to the initiator of the first common identification proposal, that is, the block link point that receives the second process definition file, so that the service participant to which the block link point belongs may modify the second process definition file.
According to the embodiment of the disclosure, the version control of the flow definition file is realized through a multi-party consensus mechanism of the block chain, so that the release or modification operation of the flow definition file can be performed only after the consensus of all the participants is obtained, the release modification of a certain participant in a single way is avoided, and the normal operation of the whole scheduling process is ensured.
