Detailed Description
In order to make the technical solutions in the present specification better understood, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below with reference to the accompanying drawings in one or more embodiments of the present specification, and it is obvious that the one or more embodiments described are only a part of the embodiments of the present specification, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from one or more of the embodiments in the present specification without inventive step, shall fall within the scope of protection of this document.
Example one
Referring to fig. 1, a schematic step diagram of a block chain consensus processing method provided in an embodiment of the present disclosure is shown, it should be understood that the method is applied in a block chain network, where the block chain network encapsulates multiple consensus interfaces, each of the consensus interfaces encapsulates a type of consensus algorithm, and an execution main body of the consensus processing method may be a block chain consensus processing device, and the block chain consensus processing device may specifically be a block chain link point.
The consensus processing method may include the steps of:
step 102: and calling a consensus interface matched with the identifier by the consensus module based on the identifier of the selected consensus algorithm.
It should be understood that in the block chain network, a plurality of consensus interfaces may be abstracted in advance, and each consensus interface is encapsulated with a class of consensus algorithms and corresponding functions thereof. Meanwhile, the number of delay blocks of the corresponding consensus algorithm is encapsulated in the consensus interface, so that the certainty of the consensus result is finally determined.
Different consensus algorithms have large differences in flow and attribute, and therefore, in a blockchain network, for consensus of a proposal, it should be ensured that the types of consensus interfaces called by all blockchain nodes are the same, that is, the consensus algorithms used by all blockchain nodes are the same.
Taking the practical Byzantine fault-tolerant algorithm PBFT and the workload proof POW as examples, the most important difference is certainty. As long as the PBFT agrees, the result is confirmed and will not be changed. However, the consensus such as POW is not very deterministic, and after a block is known, the probability of being knocked over is smaller and smaller.
The solution to this problem is that each consensus algorithm specifies a DELAY BLOCK NUMBER, which can be written as BLOCK _ DELAY _ NUMBER; for example, in the PBFT-like consensus algorithm, the number of delay blocks is 0, i.e., once the consensus result is obtained, the final result is obtained. In the POW-based consensus algorithm, the number of delay blocks may be 6, that is, after a result is known in a consensus, 6 blocks are delayed and then the result is considered as a final result. It should be understood that the value 6 is taken as an example, and the number of the delay blocks may also be set according to the actual delay situation, and the number of the delay blocks corresponding to other consensus algorithms is not short of other values, which is not described in detail herein.
Correspondingly, in order to accurately use the consensus algorithm packaged in the consensus interfaces, the number of delay blocks matched with the consensus algorithm is packaged in each consensus interface; after the consensus module calls the consensus interface matched with the identifier based on the identifier of the selected consensus algorithm, the control module obtains the NUMBER of DELAY BLOCKs from the consensus module in an initialization stage so as to finally determine the consensus result, and the control module maintains a latest BLOCK DELAY NUMBER chain.
In this embodiment of the present specification, assuming that the selection of the consensus algorithm can be implemented at the initialization of the consensus module, then, in the block-out phase, the control module can assemble the packaged transactions into a proposal; the proposal is then broadcast by the network module to other nodes within the blockchain.
In an implementation scheme, the network module may provide a registration interface, and the consensus module and other modules may all register interfaces during an initialization phase, and may provide necessary matching information, such as module identification, during registration, so that the consensus module or other modules may dynamically call the corresponding transmission interface to process when data needs to be transmitted through the network module. Therefore, the dependence coupling caused by static configuration can be avoided, especially the decoupling of the consensus module and the network module can be realized, and the consensus module can update the consensus algorithm conveniently.
Specifically, when the network module transmits data with other nodes in the block chain, the network module may perform parameter comparison based on transmission data of other modules having transmission requirements, and call a transmission interface registered by the other modules after matching, and transmit data using the transmission interface.
Step 104: and the consensus module adopts a consensus algorithm corresponding to the consensus interface to perform consensus processing on a proposal, wherein the consensus module is functionally decoupled from other modules.
In the stage of consensus, the network module receives the proposal broadcast by the block-out party and forwards the proposal to the control module; the control module checks the proposal, and takes the proposal as a new block uplink after the check is passed, wherein the new block carries a mark representing that the proposal is not subjected to consensus processing; and the control module sends the information required by the consensus of the proposal to the consensus module so that the consensus module can conveniently adopt a consensus algorithm corresponding to the consensus interface to carry out consensus processing on the proposal. Therefore, the functions of proposal verification and transaction validity verification are transferred to the control module, and the dependence of the consensus module on the control module is relieved.
After the consensus module sends the consensus result to the control module, the control module adds the consensus result to a corresponding position of a branch chain for high maintenance based on the number of delay blocks.
It should be appreciated that after the consensus module agrees to vote, the control module is notified of the consensus result; if the consensus succeeds, the control module converts the new block into a formal block and informs the consensus module to agree on a block with the next height; otherwise, the consensus module is informed to perform consensus on other blocks with the same height as the new block.
In fact, some system configuration information, such as a consensus node address list, may be used in the consensus module consensus processing process on the proposal, and the update of the system configuration information without business logic may be implemented by being placed in a transaction without depending on an intelligent contract, thereby decoupling the dependency of the consensus module on the intelligent contract and the execution module.
The common processing scheme according to the embodiments of the present disclosure is described in detail below by way of a specific example.
Referring to fig. 2, the consensus processing scheme may include the following flows:
step 202: the blockchain system is initialized.
In the initialization process, a proper consensus interface can be called through a selected consensus algorithm; meanwhile, each module can register a transmission interface in the network module so as to facilitate subsequent dynamic calling.
It should be understood that not every consensus process requires initialization, but here only the case when a consensus algorithm needs to be reselected. If the consensus algorithm does not need to be changed, the consensus process may begin based on step 204.
Step 204: and the control module of the block output node directly assembles the packaged transaction into the proxy.
Step 206: the network module of the out-of-block node broadcasts the proseal to other consensus nodes.
When the network module broadcasts the proxy, the transmission interface can be dynamically called based on the transmission data of the control module to realize the transmission of the data.
Step 208: and the network modules of other consensus nodes forward the received proposal to the control module of the node.
Step 210: and the control modules of other consensus nodes complete the verification of the proposal and add the proposal to the current block chain, and mark that the block is not yet known in a consensus manner.
Step 212: and the control modules of other consensus nodes send the hash of the propofol and other necessary information to the consensus module of the node for subsequent consensus voting.
Step 214: and after the consensus is completed, informing the control module of the consensus result.
If the consensus is successful, step 216 is performed, otherwise, step 218 is performed.
Step 216: the control modules of all consensus nodes convert the proseal into a formal block and inform the consensus module to continue to agree on the next height.
After the consensus module sends the consensus result of a certain promosal to the control plane, the control plane will add the consensus result to the appropriate position with the branched chain. If the maximum height increases, the block before the delay block number block is confirmed, the processing flow after this block can be continued, and the bifurcation before the delay block number block is cut off.
Step 218: the control module may notify the consensus module to change to another proxy retry of the same altitude.
By the technical scheme, the consensus module calls a consensus interface matched with the identification based on the identification of the selected consensus algorithm; and the consensus module adopts a consensus algorithm corresponding to the consensus interface to perform consensus processing on a proposal. Therefore, the consensus algorithm is decoupled from other parts of the block chain, and the corresponding consensus interface is called according to requirements to perform consensus processing, so that the method is flexible and convenient to realize, and can support the switching of multiple classes of consensus algorithms in the block chain system.
Example two
Referring to fig. 3, a consensus processing apparatus for a block chain provided in this specification is applied to a block chain node of a block chain network, where the block chain network is encapsulated with multiple consensus interfaces, and each of the consensus interfaces is encapsulated with a class of consensus algorithm; the apparatus 300 may include: a consensus module 302 and other modules, such as a control module 304, a network module 306, an execution module 308; wherein, the first and the second end of the pipe are connected with each other,
the consensus module 302 calls a consensus interface matched with the identifier based on the identifier of the selected consensus algorithm;
the consensus module 302 performs consensus processing on the proposal by adopting a consensus algorithm corresponding to the consensus interface, wherein the consensus module is functionally decoupled from other modules.
Optionally, as an embodiment, the number of delay blocks adapted to the consensus algorithm is further encapsulated in each of the consensus interfaces;
after the consensus module calls a consensus interface matched with the identifier based on the identifier of the selected consensus algorithm and before the consensus module performs consensus processing on a proposal by adopting the consensus algorithm corresponding to the consensus interface, the control module acquires the number of delay blocks from the consensus module in an initialization stage;
and after the consensus module sends the consensus result to the control module, the control module further adds the consensus result to a corresponding position of a highly maintained branch chain based on the number of delay blocks.
In a specific implementation manner of the embodiment of the present specification, in the block output stage, the control module assembles the packaged transactions into a proposal;
and the network module broadcasts the proposal to other nodes in the block chain.
In another specific implementation manner of the embodiment of the present specification, in the consensus phase, the network module receives a proposal broadcasted by a block-sending party, and forwards the proposal to the control module;
the control module checks the proposal, and takes the proposal as a new block uplink after the check is passed, wherein the new block carries a mark representing that the proposal is not subjected to consensus processing;
and the control module is used for sending the information required by the consensus of the proposal to the consensus module.
In a further specific implementation manner of the embodiment of the present specification, after the consensus module consensus votes, the control module is further notified of the consensus result,
if the consensus succeeds, the control module converts the new block into a formal block and informs the consensus module to agree on a block with the next height;
otherwise, the consensus module is informed to perform consensus on other blocks with the same height as the new block.
In another specific implementation manner of the embodiment of this specification, when the network module transmits data with other nodes in the block chain, the network module further performs parameter comparison based on transmission data of other modules with transmission requirements, and calls a dynamic transmission interface registered by the other modules after matching, and transmits data using the dynamic transmission interface.
In another specific implementation manner of the embodiment of the present specification, the system configuration information required by the consensus module in the consensus process does not depend on the intelligent contract of the block chain. That is, the system configuration information involved in the consensus process by the consensus module 302 does not require the execution module 308 to perform configuration updates by executing intelligent contracts. Specifically, the system configuration information can be put in the transaction by a transaction sending mode, so that the update management of the system configuration is realized. In this way, the management of system configuration information is decoupled from the intelligent contracts and execution modules 308, facilitating individual switching of consensus algorithms without affecting the maintenance of other modules.
By the technical scheme, the consensus module calls a consensus interface matched with the identification based on the identification of the selected consensus algorithm; and the consensus module adopts a consensus algorithm corresponding to the consensus interface to perform consensus processing on a proposal. Therefore, by decoupling the consensus algorithm from other parts of the block chain, corresponding consensus interfaces are called according to requirements to perform consensus processing, so that the method is flexible and convenient to implement, and can support the switching of multiple types of consensus algorithms in the block chain system.

and after the consensus module sends the consensus result to the control module, the control module further adds the consensus result to a corresponding position of a highly maintained branch chain based on the number of delay blocks.
14. A computer readable storage medium storing one or more programs that, when executed by an electronic device that includes a plurality of application programs, cause the electronic device to perform:
calling a consensus interface matched with the identifier based on the identifier of the selected consensus algorithm;
adopting a consensus algorithm corresponding to the consensus interface to perform consensus processing on a proposal, wherein the consensus module in the block chain link point of the block chain network is functionally decoupled from other modules;
the number of delay blocks adapted to the consensus algorithm is packaged in each consensus interface; the other modules include: a control module;
after the consensus module calls a consensus interface matched with the identifier based on the identifier of the selected consensus algorithm and before the consensus module performs consensus processing on a proposal by adopting the consensus algorithm corresponding to the consensus interface, the control module acquires the number of delay blocks from the consensus module in an initialization stage;
and after the consensus module sends the consensus result to the control module, the control module further adds the consensus result to a corresponding position of a highly maintained branch chain based on the number of delay blocks.
