Weekly Summary – April 28, 2025

This week, the Leios team made significant progress in protocol documentation, simulation improvements, and transaction lifecycle analysis. The team completed a draft of the Leios CIP, enhanced simulation visualization capabilities, and conducted detailed analysis of transaction processing times in Full Leios.

Simulation and analysis

• Completed simulation of 270 Full Leios scenarios at tag leios-2025w17
• Resolved all outstanding discrepancies between Rust and Haskell simulation results
• Conducted detailed transaction lifecycle analysis:
  • Average IB inclusion time: 2.4 seconds
  • Average EB referencing time: 27.6 seconds
  • Average RB referencing time: 67.2 seconds
  • Identified issues with transaction referencing and duplication in current Full Leios implementation.

Protocol documentation

• Drafted major sections of the Leios CIP using standard CIP template
• Documented evidence-based arguments for Leios necessity and viability
• Pending completion of Full Leios protocol sections due to ongoing discussions.

Rust implementation

• Publicly hosted visualization as part of the Leios documentation
• Added new "transactions" view showing transaction state graphs over time
• Fixed stability issues in long-running simulations
• Implemented leios-late-ib-inclusion extension for referencing older pipeline IBs.

Plutus benchmarking

• Documented workflow for benchmarking Plutus
• Prepared methodology for potential experiments with increased Plutus execution budgets
• Established framework for relating Plutus execution units to CPU time measurements.

Next steps

• Address transaction referencing and duplication issues in Full Leios
• Complete remaining Full Leios protocol sections in CIP
• Investigate higher transaction rates after resolution of #305
• Continue monitoring and optimizing transaction lifecycle performance.
