Embodiment Construction

[0046] The cross-chain consensus delay optimization method based on dynamic programming algorithm is characterized in that: the steps are:

[0047] Step 1) In view of the similarities and differences of the consensus mechanisms selected by the two chains during cross-blockchain transactions, the consensus mechanisms of both parties across the chains are preprocessed based on the pattern recognition method.

[0048] The specific method is as follows:

[0049] 1.1) Information acquisition: use corresponding equipment or sensors to collect information on nodes of cross-chain transactions;

[0050] 1.2) Preprocessing: standardize the collected information, that is, convert the information into digital input into the computer;

[0051] 1.3) Feature extraction and selection: Construct the respective features of the cross-chain parties to be processed into a description quantity that is convenient for comparison and analysis, that is, a feature vector, and use the feature vector to ...

Abstract

The cross-chain consensus delay optimization method based on the dynamic programming algorithm, the steps are: 1) According to the similarities and differences of the consensus mechanisms selected by the two chains during cross-blockchain transactions, preprocess the consensus mechanisms of both parties across the chain; 2) Preprocess The different consensus mechanism introduced by the mechanism will intelligently simulate the consensus process, and calculate the average delay difference t of the consensus mechanisms of the two chains; 3) The different consensus mechanism that does not meet the longest delay difference σ that the system can tolerate Input the decision controller for processing. Under the premise of not changing the consensus mechanism of the two chains themselves, the decision controller selects a consensus mechanism M suitable for different consensus mechanisms based on the dynamic programming algorithm; 4) Select some trusted nodes of the two chains, and adopt the steps The consensus mechanism M obtained in 3) reaches a consensus on the verification of cross-chain transactions. Through the above method, the present invention provides a cross-chain consensus delay optimization method with simple steps and good processing effect.

Description

technical field [0001] The invention proposes a cross-chain consensus delay optimization method based on a dynamic programming algorithm, aiming at the influence of excessive delay difference of the cross-chain consensus mechanism on the system. Background technique [0002] With the rapid development of blockchain applications, the demand for blockchain in different business scenarios has further increased. The number of global blockchains is increasing, and the isolation of different blockchain networks makes it impossible to effectively transfer digital assets, cross-chain communication and other operations between chains. With the continuous enrichment and complexity of blockchain application scenarios , More and more blockchain projects propose cross-blockchain transaction requirements and solutions. The cross-blockchain transaction mechanism breaks the isolation of the blockchain and enables the interconnection and interaction between different blockchains. It greatly...
