Description
Technical Field
The invention relates to the technical field of block chains, in particular to a self-adaptive configuration transaction packing method based on a block chain platform.
Background
The block chain technology is a distributed book technology and is also a point-to-point cooperative network. The cooperative nodes maintain data together, each cooperative node has a complete data, and the data of all the cooperative nodes are kept consistent. All of this requires a consensus mechanism that relies on blockchains.
The consensus mechanism comprises the following steps: the cooperative node distributes the block (each packaged transaction is called a block) to other cooperative nodes for consensus verification, and after the block is verified to be correct (namely all cooperative nodes achieve consensus), the other cooperative nodes synchronize the block.
The consensus algorithm currently used by most blockchain platforms is PBFT (practical byzantine fault-tolerant algorithm). Under an ideal environment (namely, the conditions such as network delay and the like are not considered), the processing capacity of the consensus algorithm can only reach five-six hundred tps (the number of messages processed per second), and the consensus algorithm cannot adapt to the service requirements under different scenes. For example, in the case of batch data registration, a large number of blocks are generated, which results in a large reduction in the efficiency of consensus and a reduction in the efficiency of data uplink.
Disclosure of Invention
The invention aims to provide a self-adaptive configuration transaction packing method based on a block chain platform aiming at the defects of the prior art, so as to solve the problems that the prior block chain technology has poor processing efficiency in a packing consensus stage and can not meet the application requirements of different scenes.
In order to achieve the purpose, the invention has the following technical scheme: a self-adaptive configuration transaction packaging method based on a block chain platform comprises the following steps:
the block chain platform processes a plurality of transaction requests simultaneously, when the transaction reaches a packing time threshold or a transaction number threshold, the platform packs all or part of the transaction requests according to the sequence of the transaction requests, and performs consensus processing on the packed transaction information on the block chain nodes;
two parameters that pack blockchain platform control transactions: the packaging time t, the transaction number n, the packaging time initial value P and the transaction number initial value q are configured in a configuration file, and a parameter strategy is configured in the configuration file;
the block chain platform adaptively reads a parameter strategy in the configuration file according to the transaction request number per second in the previous time period i to obtain an optimal packaging parameter, and refreshes the packaging time and the transaction pen value;
the block chain platform carries out transaction packaging and node consensus according to the refreshed packaging parameters;
the design principle of the parameter strategy is as follows:
when the transaction request number per second in the previous time period i is smaller than the initial transaction number value q, the block chain platform adopts a real-time registration strategy, the block chain platform is divided into a plurality of grade intervals according to the transaction request number per second in the previous time period i, the packaging time of the grade corresponding to the transaction request number is synchronously increased along with the increase of the transaction request number, and the transaction request number in the highest grade packaging time is smaller than the initial transaction number value q;
the transaction request number per second in the current time period i is larger than or equal to the initial value q of the transaction number, the block chain platform adopts a batch registration strategy, the transaction request number per second in the previous time period i is divided into a plurality of grade intervals, the transaction number of the grade corresponding to the transaction request number is synchronously increased along with the increase of the transaction request number, the transaction request number received in the packaging time t is larger than the transaction number n, and the transaction number of the highest grade does not exceed the upper limit of the block chain platform for processing transactions.
Further, the blockchain platform can read the configuration file at any time and refresh the values of the packing parameters.
Furthermore, the adaptive block chain platform has universality, can adapt to any scene application, and has higher processing efficiency.
Further, the packaging parameters are changed according to the current transaction request number; the transaction request number in a certain time period is less, the transaction information is required to be registered in real time, and the packaging time is set to be a smaller value; along with the increase of the number of transaction requests, the corresponding proportion of the packaging time can be increased so as to improve the efficiency; when a large number of transaction requests exist in a short time, the transaction number is increased, batch packaging is carried out, the number of blocks generated by the block chain platform is reduced, and the batch transaction registration efficiency is improved.
The invention has the following beneficial effects:
1. the block chain platform configures two parameters for controlling transaction packaging, configures different parameter strategies according to different scenes, and aims to improve the data chaining efficiency under different scenes. Compared with the prior fixed parameters, the method is more flexible and efficient.
For example, using the past fixed parameter, the packing time in the packing parameter is set to a small value, and it is found that when the number of transaction requests is small, data can be quickly registered on the block chain. But as the number of transaction requests increases, the data chaining efficiency does not increase or decrease inversely. The reason for this is that as the number of transaction requests increases, the number of blocks also increases rapidly, exceeding the upper limit of the block chain platform consensus algorithm. In such a scenario, it is necessary to reduce the generation of blocks, set the packing time to a larger value, and let the blockchain platform trigger the transaction packing operation according to the threshold of the transaction number.
2. The blockchain platform is adaptive according to different scene adjustment parameters. The parameter policy is configurable and extensible. The setting of the optimization parameter strategy can be increased according to the application scenes with rich blocks.
3. The block chain platform adaptive configuration transaction packing method can improve the efficiency of data chaining on the whole.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1, the present application provides an adaptive configuration transaction packing method based on a blockchain platform, which includes:
the block chain platform processes a plurality of transaction requests simultaneously, when the transaction reaches a packing time threshold or a transaction number threshold, the platform packs all or part of the transaction requests according to the sequence of the transaction requests, and performs consensus processing on the packed transaction information on the block chain nodes;
two parameters that pack blockchain platform control transactions: the packaging time t, the transaction number n, the packaging time initial value P and the transaction number initial value q are configured in a configuration file, and a parameter strategy is configured in the configuration file;
the block chain platform adaptively reads a parameter strategy in the configuration file according to the transaction request number per second in the previous time period i to obtain an optimal packaging parameter, and refreshes the packaging time and the transaction pen value; the adaptive block chain platform has universality, can adapt to any scene application, and has higher processing efficiency;
the block chain platform carries out transaction packaging and node consensus according to the refreshed packaging parameters;
the design principle of the parameter strategy is as follows:
when the transaction request number per second in the previous time period i is smaller than the initial transaction number value q, the block chain platform adopts a real-time registration strategy, the block chain platform is divided into a plurality of grade intervals according to the transaction request number per second in the previous time period i, the packaging time of the grade corresponding to the transaction request number is synchronously increased along with the increase of the transaction request number, and the transaction request number in the highest grade packaging time is smaller than the initial transaction number value q;
the transaction request number per second in the current time period i is larger than or equal to the initial value q of the transaction number, the block chain platform adopts a batch registration strategy, the transaction request number per second in the previous time period i is divided into a plurality of grade intervals, the transaction number of the grade corresponding to the transaction request number is synchronously increased along with the increase of the transaction request number, the transaction request number received in the packaging time t is larger than the transaction number n, and the transaction number of the highest grade does not exceed the upper limit of the block chain platform for processing transactions.
The invention changes the packaging parameters according to the current transaction request number; the transaction request number in a certain time period is less, the transaction information is required to be registered in real time, and the packaging time is set to be a smaller value; along with the increase of the number of transaction requests, the corresponding proportion of the packaging time can be increased so as to improve the efficiency; when a large number of transaction requests exist in a short time, the transaction number is increased, batch packaging is carried out, the number of blocks generated by the block chain platform is reduced, and the batch transaction registration efficiency is improved.
In one specific application, the packed parameter policy is as follows:
setting a packing time initial value P to be 0.05 and setting a transaction number initial value q to be 100;
when the transaction request number a received in each second in the previous time period i of the blockchain platform is less than or equal to b (b is a self-defined threshold value, b is less than q, for example, 10 is taken), the blockchain platform adopts a real-time registration strategy, the packing time t is set as a packing time initial value P (for example, 0.05s), and data packing and node consensus are immediately carried out when the transaction request is received. As the number of transaction requests per second received by the blockchain platform in i seconds increases, for example, when the number of transaction requests per second a is greater than b and less than or equal to c (c is a self-defined threshold, and c is less than q, for example, 20), the blockchain platform may read the corresponding configuration parameter value according to the magnitude of the increased number. The strategy for real-time registration may be sequentially set with 10 level intervals (e.g., within i seconds, a < 10, t equal to 0.05, 10< a <20, t equal to 0.1, 20< a < > 30, t equal to 0.15, 30< a < > 40, t equal to 0.2, 40< a < > 50, t equal to 0.25, 50< a < > 60, t equal to 0.3 …, and so on, the number of transaction requests in the highest level packing time, a, is less than 100).
When the number of transaction requests per second is too large, a threshold number of transactions is triggered. In this case, the blockchain platform adopts a batch registration strategy to increase the transaction pen value n. When the transaction request number a per second in i seconds is greater than or equal to the transaction number initial value q and less than w, the packing time t is set to a larger value (for example, 5 seconds). And when the transaction request number a per second in i seconds is more than or equal to w and less than f, updating the transaction number n to w. Similarly, 10 level intervals may be set in sequence (for example, within i seconds, 100< ═ a <200, n is equal to 100, 200< ═ a <300, n is equal to 200, 300< ═ a <400, n is equal to 300, 400< ═ a <500, n is equal to 400, 500< ═ a <600, n is equal to 500 …, and so on, the highest level transaction number does not exceed the upper limit of the block chain platform for processing transactions).
The real-time registration strategy and the batch registration strategy both increase the value adjustment range of 10 gradients, so that the parameter selection is more reasonable. Therefore, the block chain platform adaptively selects the optimal configuration according to different transaction request quantity scenes, improves the processing efficiency of the block chain platform as a whole and has universality.
The foregoing is only a preferred embodiment of the present invention, and although the present invention has been disclosed in the preferred embodiments, it is not intended to limit the present invention. Those skilled in the art can make numerous possible variations and modifications to the present teachings, or modify equivalent embodiments to equivalent variations, without departing from the scope of the present teachings, using the methods and techniques disclosed above. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
