Description

Decentralized dynamic optimization method, system, device and medium for permissioned blockchain Technical Field

[0001] The present invention relates to the field of blockchain optimization technology, and in particular to a decentralized dynamic optimization method, system, device and medium for permissioned blockchain. Background Art

[0002] Currently, the number of methods for dynamic blockchain optimization is increasing year by year. Blockchains are complex dynamic systems whose performance characteristics are affected by the underlying system state. Therefore, these methods aim to dynamically adjust the configuration of blockchain systems to maximize performance under various system states.

[0003] However, the fundamental principle of blockchain is that no single entity can control the state of a blockchain system. System participants must collectively agree on any actions that affect the system state. Therefore, dynamic blockchain optimization cannot be handled by a single authority. This is because, with a single point of control, a malicious or compromised centralized optimization service could enforce vulnerable configurations, attempt to control the blockchain system, or add malicious transactions to the blockchain. Therefore, a decentralized approach to dynamic blockchain optimization is urgently needed.

[0004] Summary of the Invention

[0005] The present invention aims to address at least one of the technical problems existing in the prior art. To this end, the present invention proposes a decentralized dynamic optimization method, system, device, and medium for permissioned blockchains. These methods, through the construction of optimization nodes, an optimization framework, and an optimization chain, enable decentralized dynamic optimization of permissioned blockchains, improving both throughput and security.

[0006] In a first aspect, an embodiment of the present invention provides a decentralized dynamic optimization method for a permissioned blockchain, comprising:

[0024] The optimization result and the optimization block of the proposer node are compared. If the optimization result and the optimization block are consistent, the optimization block is valid for the blockchain optimization; otherwise, the optimization block is invalid for the blockchain optimization.

[0055] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0056] In the description of the present invention, if there is a description of first, second, etc., it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0057] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0058] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0059] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0060] Before further describing the embodiments of the present application in detail, the scenarios involved in the embodiments of the present application are described. The application scenarios of the embodiments of the present application are illustrated with some actual examples below.

[0061] Referring to Figure 1, it depicts the general architecture of a permissioned blockchain system, including a centralized optimization service 100, nodes 101, a blockchain 102, a transaction processing pool 103, a consensus protocol (data) 104, block producer nodes 105, and a peer-to-peer network 106. This general architecture relies on the centralized optimization service to achieve dynamic reconfiguration. In this permissioned blockchain system, node 101 generates and broadcasts transactions to the blockchain system. These broadcast transactions are captured by block producer nodes 105, granting node 101 the right to participate in the consensus process and obtain consensus protocol 104. Before being included in a data block, transactions are considered unconfirmed and stored in the node's transaction processing pool 103, awaiting inclusion. To achieve reconfiguration, the system relies on the centralized optimization service 100, which regularly observes the system state, calculates optimization decisions based on the latest state, and provides them to the centralized optimization service 100. A permissioned blockchain is a blockchain system that operates through a permissioned network. Compared to permissionless blockchain systems, where anyone can participate anonymously, permissioned blockchain systems require that nodes' identities be verified by an authentication service before they can participate. The decentralized dynamic optimization method for permissioned blockchains of the present invention is applicable to permissioned blockchain systems. Therefore, in the embodiments of this application, the blockchains are all assumed to be permissioned blockchains.

[0062] 2 , which describes how the decentralized dynamic optimization method for a permissioned blockchain of the present invention is applied to a permissioned blockchain system. Compared to the general architecture of a permissioned blockchain system, an optimization chain 200, a consensus protocol (optimization) 201, an optimization framework 202, and an optimization node 203 are added. The embodiments of the present application may all be applied to the scenario described in FIG. 2 .

[0063] 3 , in some embodiments of the present invention, a decentralized dynamic optimization method for a permissioned blockchain is provided, comprising:

[0064] Step S100: Obtain the system status of the permission blockchain.

[0065] Step S200: construct an optimization node, an optimization framework, and an optimization chain; wherein the optimization framework includes a blockchain configuration optimization algorithm; and each optimization node includes an instance provided by the optimization framework.

[0066] It's important to note that the optimization framework is a black box, capable of being a complete blockchain optimization solution. The core of this blockchain optimization solution lies in the blockchain configuration optimization algorithm. For example, an optimization algorithm based on Deep Q Learning (DQL) can optimize block producers, consensus algorithms, block sizes, and block intervals through this protocol. Dynamic adjustments improve the scalability of the underlying blockchain without compromising decentralization, latency, or security. When integrated, each optimization node will contain an instance of the blockchain configuration optimization algorithm. There is no restriction on whether each optimization node uses the same blockchain configuration optimization algorithm. Referring to Figure 9, blockchain configuration optimization algorithms can also include those described in "Performance Optimization for Blockchain-Enabled Industrial Internet of Things (IIoT) Systems: A Deep Reinforcement Learning Approach," "Digital twin for dynamic management of blockchain systems," and "PBRL-TChain: A performance-enhanced permissioned blockchain for time-critical applications based on reinforcement learning." Different blockchain configuration optimization algorithms may have different input and output data types, resulting in different block structures for the corresponding optimization blocks. The block structure of the optimization block here will be adjusted accordingly, but no restrictions are imposed on the block structure. "Performance Optimization for Blockchain-Enabled Industrial Internet of Things (IIoT) Systems: A Deep Reinforcement Learning Approach," published in the IEEE Transactions on Industrial Informatics, proposes a deep Q-learning-based optimization protocol that optimizes block producers, consensus algorithms, block size, and block intervals. Dynamic adjustments improve the scalability of the underlying blockchain while maintaining system decentralization, latency, and security. "Digital twin for dynamic management of blockchain systems" refers to a dynamic management system for blockchain systems based on digital twins, and related algorithms are included in arXiv."PBRL-TChain: A performance-enhanced permissioned blockchain for time-critical applications based on reinforcement learning" describes a performance-enhanced permissioned blockchain for time-critical applications based on reinforcement learning. It is commonly used in underlying public blockchain protocols like TChain. Since the example algorithms are all published in English journals, the inputs and outputs are also expressed using the variables described in the English journals.

[0067] Step S300: Input the system state into the instance to generate a corresponding optimization block; the optimization block includes the optimized system configuration information obtained through the blockchain configuration optimization algorithm.

[0068] Step S400: Consensus verification is performed on the optimization block by each optimization node to obtain a consensus proof result of the optimization block.

[0069] Step S500: Store the optimized block in the optimized chain according to the consensus proof result.

[0070] Step S600: Optimize the configuration of the permissioned blockchain according to the optimized chain of the stored optimized blocks.

[0071] This method first constructs optimization nodes, an optimization framework, and an optimization chain based on the system state of a permissioned blockchain, achieving a well-designed dynamic adjustment architecture that can adjust in real time based on the permissioned blockchain's system state. This architecture is also applicable to a wider range of task scenarios and easily migrated. Secondly, corresponding optimization blocks are generated through instances. Since instances are provided by the optimization framework, they can also be adjusted through the optimization framework. Through instances, different permissioned blockchain configuration optimization algorithms can be implemented to generate optimization blocks, improving the robustness of optimization block generation. Each optimization node then performs consensus verification on the optimization block, making each optimization node's optimization block decision-making decentralized. The optimization block is then stored through the optimization chain, making it easy for the permissioned blockchain to retrieve the configuration information in the optimization block. The optimization chain also allows for encryption and optimization traceability. Finally, the permissioned blockchain is configured and optimized based on the optimization chain of the stored optimization block, combining the advantages of achieving dynamic permissioned blockchain optimization capabilities while maintaining the key property of decentralization.

[0072] 4 , in some embodiments of the present invention, generating a corresponding optimization block from a system state input instance includes the following steps:

[0073] Step S310: A proposer node is selected from all optimized nodes using a preset proposer selection algorithm.

[0074] It should be noted that the proposer node is selected from all optimization nodes. Polling of each optimization node may be required, and a threshold limit may be set for the number of times the optimization node has been selected. No specific restrictions are set here.

[0075] Step S320: Input the system state into the instance corresponding to the proposer node, and calculate to obtain the optimized block.

[0076] It should be noted that by calculating the blockchain configuration optimization algorithm through an example, the optimized configuration information will be obtained and stored in the optimized block.

[0077] The proposer selection algorithm selects the proposer node, achieving a decentralized effect. At the same time, different proposer selection algorithms can adapt to more blockchain task scenarios and different precision requirements, improving the security and efficiency of optimized block generation.

[0078] 5 , in some embodiments of the present invention, each optimization node performs consensus verification on the optimization block to obtain a consensus proof result of the optimization block, including the following steps:

[0079] Step S410: Initiate a consensus process through the proposer node; the consensus process uses a preset consensus protocol.

[0080] It should be noted that the consensus protocol in this embodiment is a consensus protocol for optimized blocks, namely, consensus protocol (optimization) 201.

[0081] Step S420: Use other optimized nodes except the proposer node as validator nodes of the consensus process.

[0082] Step S430: If the validator node receives the optimization block and verifies that the optimization block is valid for the permission blockchain optimization, the consensus proof result is modified to pass the consensus verification; if the validator node does not receive the optimization block within the time threshold or the validator node verifies that the optimization block is invalid for the permission blockchain optimization, the consensus proof result is modified to fail the consensus verification.

[0083] Through the preset consensus protocol, the proposer node and other optimization nodes are all consensus-driven to ensure the implementation of decentralization. At the same time, the effectiveness of the optimization block on the permissioned blockchain is simulated and verified by the validator node to further ensure the optimization effect of the optimization block.

[0084] 6 , in some embodiments of the present invention, verifying by a validator node whether an optimization block is valid or invalid for a permissioned blockchain optimization includes the following steps:

[0085] Step S431: Verify the signature of the proposer node based on the system state of the permissioned blockchain and verify the block structure of the optimized block. If the signature of the proposer node matches and the block structure of the optimized block is correct, the optimization result is obtained by performing configuration optimization using the optimized block through the validator node.

[0086] It should be noted that before becoming a proposer node, as an optimization node, it already has its own signature. After becoming a proposer node, only some timestamp information changes, while the hash data of the signature does not change. Therefore, the identity verification result of the proposer node can be obtained by verifying whether the signature of the proposer node matches. At the same time, the optimization block is calculated by the blockchain configuration optimization algorithm through an instance. Therefore, the information of the optimization block is determined by the configuration owned by the permissioned blockchain. Therefore, the block structure of the optimization block is also related to the configuration owned by the permissioned blockchain. Therefore, the identity verification result of the optimization block can be obtained by optimizing the block structure of the optimization block. Finally, after the identity verification results of the proposer node and the optimization block are both passed, the optimization result is obtained by the verifier node using the optimization block to perform configuration optimization. The configuration optimization of the verifier node using the optimization block can be achieved by simulating the verifier, and no specific restrictions are made here.

[0087] Step S432: Compare the optimization result and the optimization block of the proposer node. If the optimization result and the optimization block are consistent, the optimization block is valid for the blockchain optimization; otherwise, the optimization block is invalid for the blockchain optimization.

[0088] It should be noted that the optimization result is equivalent to the simulation result, and the optimization block stores the optimization configuration information obtained through the optimization block theory. If the optimization result and the optimization configuration information of the optimization block are inconsistent, it is very likely that the optimization block has been maliciously tampered with during transmission. Therefore, in this step, the optimization result and the optimization block need to be compared.

[0089] The security and validity of the optimization block are further guaranteed through multiple verifications of the proposer node’s authentication results, the optimization block’s authentication results, and the optimization results.

[0090] 7 , in some embodiments of the present invention, storing the optimized block in the optimized chain according to the consensus proof result includes the following steps:

[0091] Step S510: Detect the consensus proof result.

[0092] Step S520: If the consensus proof result passes the consensus verification, the optimization block corresponding to the consensus proof result is stored in the optimization chain.

[0093] Judging whether to store the optimized block based on the consensus proof results can save a certain amount of computing power resources, while also avoiding the optimization of invalid optimized blocks in the permissioned blockchain, which wastes a lot of computing power resources.

[0094] 8 , in some embodiments of the present invention, performing configuration optimization on a permissioned blockchain according to an optimized chain of stored optimized blocks includes the following steps:

[0095] Step S610: Obtain the latest optimized block in the optimization chain of stored optimized blocks.

[0096] Step S620: Compare the latest optimized block with the current configuration of the permission blockchain. If the latest optimized block and the current configuration of the permission blockchain are different, update the permission blockchain using the latest optimized block.

[0097] It should be noted that the latest optimized block in the optimized chain can be obtained before each transaction on the permissioned blockchain or after each transaction on the permissioned blockchain, and a time period can also be set, which is not specifically limited here.

[0098] By real-time monitoring of the latest optimized block of the optimization chain and the current configuration of the permissioned blockchain, the current configuration of the permissioned blockchain is guaranteed to be the latest optimized block, thereby improving the throughput of the permissioned blockchain.

[0099] In some embodiments of the present invention, the proposer selection algorithm includes a round-robin algorithm and a sticky-proposer algorithm.

[0100] It should be noted that when the proposer selection algorithm is round-robin, the proposer node is updated after each optimization block is generated, so that every optimization node will traverse and become the proposer node. When the proposer selection algorithm is sticky-proposer, a single proposer node generates all optimization blocks, unless the remaining optimization nodes detect an error or malicious node, in which case a proposer node change vote is initiated, and the optimization node designated by the voting result is used as the new proposer node.

[0101] According to the round-robin algorithm and the sticky-proposer algorithm, a variety of proposer selection methods can be realized. At the same time, the round-robin algorithm and the sticky-proposer algorithm are mainstream selection algorithms, which can provide a stable and fair election method.

[0102] 10 , an embodiment of the present invention further provides a decentralized dynamic optimization system for a permissioned blockchain, including a blockchain system module 1001, a decentralized dynamic optimization module 1002, an optimized block generation module 1003, a consensus verification module 1004, an optimized chain storage module 1005, and a blockchain configuration optimization module 1006, wherein:

[0103] The blockchain system module 1001 is used to obtain the system status of the permissioned blockchain.

[0104] The decentralized dynamic optimization module 1002 is used to construct an optimization node, an optimization framework, and an optimization chain; wherein the optimization framework includes a blockchain configuration optimization algorithm; and each optimization node includes an instance provided by the optimization framework.

[0105] The optimization block generation module 1003 is used to input the system state into the instance to generate the corresponding optimization block; the optimization block includes the optimized system configuration information obtained by the blockchain configuration optimization algorithm.

[0106] The consensus verification module 1004 is used to perform consensus verification on the optimization block through each optimization node to obtain a consensus proof result of the optimization block.

[0107] The optimization chain storage module 1005 is used to store the optimization block into the optimization chain according to the consensus proof result.

[0108] The blockchain configuration optimization module 1006 is configured to optimize the configuration of the permissioned blockchain according to the optimization chain of the stored optimization blocks.
