### System-dynamics simulation of throughput techno-economics

A first draft system-dynamics simulation models the techno-economics of changes in throughtput on Cardano:

- Features
- Movement of funds from the Reserve to the Treasury and to the rewards.
- Collection of fees from transactions into the rewards pot.
- Dispersement of the rewards pot to pools and users.
- Ledger size
- Pool costs and profitability

### Rust Simulation

Bug fixes and performance improvements. The sim was slow, because of
- Not batching filesystem operations
- Not yielding in the main thread when too many items were in play
- Not correctly handling when the simulation ends early
