This treasury withdrawal requests **₳18,263,496.00** (USD $4,565,874.00) to fund Tweag by Modus Create's delivery of 3 work packages across core infrastructure areas for the Cardano ecosystem over 2026–2027. The primary focus is the **mainnet deployment of Peras** (faster finality: ~2 min vs. ~12 min today), alongside improvements to resilience, scalability, developer tooling, and network observability. Work packages include: - **Peras v1** – production cryptography, KillSwitch, mainnet readiness and further support and maintenance - **History Expiry** – partial-history nodes to reduce SPO storage costs - **Conformance Testing** – CTC framework extended for Peras and Leios Intersect is requested to serve as proposal and contract administrator. All deliverables are open-source and publicly tracked.

## Problem Statement Cardano's next growth phase depends on two critical protocol upgrades: **Peras** (faster finality) and **Leios** (higher throughput). Together they unlock significantly higher transaction volume, staking rewards, and TVL. However, these upgrades do not deliver value on their own — they require: 1. **Production-grade mainnet delivery** — Peras v1 remains undeployed on mainnet. Real cryptography, operational tooling, and Hard Fork readiness must be completed. 2. **Resilience and correctness scaffolding** — Protocol changes of this complexity require conformance testing, mutation testing, adversarial fork simulation, and audit infrastructure to de-risk deployment. 3. **Sustainable node economics** — Increased throughput from Leios will cause SPO disk usage to surge (~1 GB/hour at 100–1000 TPS). Without History Expiry, full-history requirements will become economically prohibitive, threatening decentralization. Tweag has been engaged on Cardano's core infrastructure since January 2018, leading the consensus and ledger teams, implementing Ouroboros Genesis, and contributing to Peras design. This proposal represents the natural continuation of that work, focused on ensuring prior investments reach mainnet and are adopted by the community.
