As Cardano evolves under full community governance in 2025, scalability remains one of the top priorities.

Ouroboros Leios is a major redesign of Cardano’s Ouroboros consensus, designed to achieve significant scalability and throughput – pushing Cardano well beyond its current limits. As Cardano’s long-term scaling engine, Leios is a transformative upgrade that paves the way for…

Stake pool operations lie at the heart of Cardano decentralization, enabling servers to reach a consensus agreement across the network. Our groundbreaking Ouroboros proof-of-stake consensus protocol allows pool operators to reach agreement on the validity of transactions and sign a block, which is then immutably recorded on the Cardano blockchain.

On the Shelley path to…

Taking a decentralized approach to governance and decision-making is proving to be more efficient in many spheres than the centralized, authority-based model that became the norm in so many areas in the last century. At IOHK, we believe that blockchain technology offers a way to encourage participation in collective action. And we are building just such a system, so Cardano can…
