Weekly Summary – May 5, 2025
This week, the team focused on simulation analysis, security improvements, and protocol documentation, making significant progress across multiple areas.
Simulation analysis and performance
The team executed the first high-throughput simulations of Leios using the Rust simulator, with transaction rates reaching up to 1,000 TPS. They introduced two key efficiency metrics to quantify system performance:
- Temporal efficiency, which measures the fraction of submitted transactions that make it into the ledger, with nearly 100% indicating optimal transaction inclusion
- Spatial efficiency, which represents the ratio of transaction size to total ledger size (including IBs, EBs, and RBs), with higher values indicating better storage optimization.
Recent revisions to Full Short Leios have shown promising improvements in both efficiency metrics. The simulations revealed an average transaction lifecycle of approximately 100 seconds from submission to ledger inclusion.
The analysis produced several key visualizations that demonstrate the system's performance:

Protocol documentation and analysis
The team conducted an extensive analysis of transaction throughput and block characteristics, producing several key visualizations:

Figure 6: Comparative transaction lifecycle between Praos and Leios
The team also completed a comprehensive profitability analysis for Leios SPOs, considering various deployment scenarios:
- Evaluated infrastructure costs across premium and value cloud providers
- Demonstrated profitability without reserve contributions at 50+ TPS
- Documented the impact of diminishing future rewards due to reserve depletion
- Analyzed comparative economics between Praos and Leios SPOs.

Security and infrastructure improvements
The team addressed several security vulnerabilities in web applications through a series of patches:
Protocol enhancements
Recent protocol improvements include:
- Implementation of revisions to Full Short Leios design to enhance both temporal and spatial efficiency
- Optimization of protocol parameters for improved transaction processing
- Development of a new sharding strategy in Rust simulation
- Enhanced logging system for tracking spatial efficiency metrics.
