# Klaytn Improvement Reserve: Progress 3 & Algorithm Report

## Parallel-structured Blockchain for Scalability and Stability

Date : 2022.08.29

Progress Technical Report 2: [Progress 3 & Algorithm Report](https://drive.google.com/file/d/1KQxl0vPqg-93wsSQ6-ZjApJ5sw1Tz06i/view?usp=sharing)

## Summary

Progress 3 & Algorithm Report covers in-depth algorithm analysis of parallel blockchain’s consensus algorithm. You can find out pseudo code of consensus algorithm.

For in-dept algorithm analysis and validation, we did some tests like ‘block commit time measurement’ and ‘PIBFT Max TPS test’, etc. Based on test results, we re-designed,analyzed and validated consensus algorithm in better way. As a result, we re-defined this project’s goal. **Parallel-structured blockchain is a trilemma technology that fast blockchains can improve stability and decentralization without loss of scalability.**

## Project Milestones and Schedule
