IO: Consensus – Leios (Ship It): $1.05M paid of $4.64M from Cardano's treasury, through Intersect Treasury Contracts 2, in 9 payments. The next payment unlocks 30 Nov 2026.

Approved by IO: Consensus Initiative.

About the project

IO will deliver Leios, a consensus extension designed to dramatically increase Cardano’s throughput capacity. The programme validates technical feasibility on real infrastructure, addresses all identified security threats, integrates Leios into the Dijkstra ledger era, produces a mainnet-ready release candidate, prepares all governance artifacts for the hard fork, and activates Leios on public testnets on the path to mainnet. Success is defined by at least a 3x increase in throughput capacity from baseline, with Leios activated on preview testnet.
