**Proposal as pdf: [https://ipnso-com.ipns.dweb.link/?cid=QmPdBp8QjKaPdYdvwLxzDiCxX85hGx8H6rxbSvTTuLkcx2](https://ipnso-com.ipns.dweb.link/?cid=QmPdBp8QjKaPdYdvwLxzDiCxX85hGx8H6rxbSvTTuLkcx2)**
Cardano needs a step change in throughput to meet its 2030 ambitions, and Leios is how it gets there. This proposal funds the path from public testnet to a mainnet-ready release candidate — delivering a 10–65x increase in transaction capacity.
Why this scale matters: Cardano's 2030 strategy targets growth from roughly 800,000 monthly transactions to over 27 million. At sustainable utilization levels, that requires at least 6x current capacity. Leios delivers 10x or more — giving significant room to grow. It works by enhancing Cardano's existing Ouroboros Praos consensus with Endorser Blocks and committee-based validation, increasing throughput without compromising decentralization or making stake pool operations unviable.
The current budget cycle (ending June 2026\) delivers an early public testnet. This proposal picks up from there and focuses on three objectives. First, a release candidate: maturing the implementation through substantial engineering, conformance testing against formal specifications, and integration into the primary node. Second, high confidence: systematic validation through parameter exploration, load testing, and adversarial red-teaming on the public testnet. Third, hard-fork enabling: everything within IO's control to make the Leios hard fork possible, including stable interfaces for ecosystem tools (DB-Sync, Mithril, Blockfrost), SPO and developer workshops, governance artifact preparation, and contingency procedures. The proposal explicitly excludes external dependencies like the community hard-fork vote from its acceptance criteria — those are captured as risks, not promises. Intersect administers all funds through milestone-based smart contracts with independent oversight. Unspent funds return to the Treasury.
