# Leios logbook

## 2025-02-06

### Enhancements to online cost calculator

In response to queries and suggestions, the [online Leios cost calculator]() has been enhanced:

- Users can select costs for either hyperscale providers (like AWS, Azure, and GCP) or discount providers (Hetzner, OVH Cloud, etc.).
- Costs default to that of a discount provider.
- Users can optionally amortize ledger storage costs perpetually vs compute a first-month snapshot of storage costs.
- Deployments default to a single relay instead of two.
- The disk compression default was reduced to a conservative 50%.

## 2025-01-31

## Formal Methods
### Formal Methods

- Finalizing executable specifications for Simplified and Short Leios
- Short Leios spec extracted to Haskell for conformance testing
