Weekly Report - May 13, 2024

1. Optimized the mechanism for repeated validation of data permissions in the contract

Frequently validating data permissions during contract execution has always been a performance bottleneck. This week, we focused on optimizing this issue and introduced a permission validation mechanism based on caching, avoiding a large number of redundant checks. After comprehensive testing, the optimized contract execution efficiency has improved by 20%-30%.

2. Optimized data operations in the underlying storage layer

As the core infrastructure of the system, the performance of the storage layer directly determines the overall performance ceiling. We approached it from multiple angles and thoroughly optimized the storage layer, including reducing data copying, optimizing index structures, and eliminating redundant object creation. After this round of optimization, the read and write performance of the storage layer has improved by 25% and 18% respectively.

3. Fixed the issue of virtual machine abnormally loading code block objects

Last week, we discovered that the virtual machine would cause exceptions when loading code block objects in certain special scenarios, affecting the normal operation of the execution engine. We highly prioritized this issue and immediately formed an emergency team. After unremitting efforts, we finally thoroughly analyzed and solved the root cause, ensuring that the virtual machine can stably load all code blocks.

4. Optimized the environment variable processing logic in the execution engine

The logic for processing environment variables in the execution engine was too complex, posing a significant challenge for subsequent code maintenance. This week, we thoroughly refactored the code for this module, streamlined the logic implementation, improved readability and maintainability, and fixed a data race defect, comprehensively enhancing the robustness of the execution engine.
