## Pseudo-mainnet topology simulation

- Designed and initiated comprehensive simulations for 1 through 300 TPS using the new [pseudo-mainnet topology](https://github.com/input-output-hk/ouroboros-leios/blob/main/data/simulation/pseudo-mainnet/)
- Designed and initiated comprehensive simulations from 1 to 300 TPS using the new [pseudo-mainnet topology](https://github.com/input-output-hk/ouroboros-leios/blob/main/data/simulation/pseudo-mainnet/)
- Created a realistic 10,000-node network with:
- 2,657 block producers and 7,343 relay nodes
- Realistic stake distribution and geographic distribution
- Two relays per block producer with realistic latencies
- 298,756 total connections with 6-hop network diameter
- Observed significant performance challenges with large-scale simulation:
- Rust simulation: 6 minutes of network time in 10 hours at 1 TPS
- Performance degradation at higher TPS rates (1 minute network time in 10 hours at 300 TPS)
- Observed significant performance challenges within the large-scale simulation:
- Rust simulation: six minutes of network time in 10 hours at one TPS
- Performance degradation at higher TPS rates (one minute network time in 10 hours at 300 TPS)
- Haskell simulation requires optimization for practical large-network analysis.

## Rust simulation enhancements

- Implemented random sampling of transactions from the Leios memory pool to ensure different IBs contain different transactions when possible
- Added simulation support for Leios variant where IBs contain transaction references rather than full transaction bodies
- Added simulation support for the Leios variant, where IBs contain transaction references rather than full transaction bodies
- Enhanced transaction handling for high-traffic scenarios.
