Cardano’s Ouroboros Leios Goes Live for Community Feedback
Cardano is advancing its long-planned upgrade aimed at increasing network throughput and is inviting the community to weigh in.The “Ouroboros Leios” Cardano Improvement Proposal (CIP) is now publicly available in the Cardano Foundation’s repository.On August 27, Input Output’s Director of Software Architecture, Nicolas “BeRewt” Biri, announced the public release of the Leios CIP. Although too early to celebrate the upgrade, he notes that this submission is a significant milestone, and the team wants to ensure the community agrees with it first. So, here it is, we know have a public and submitted CIP for Leios. More than ever, it's now time for feedback.It may be too early to celebrate, as we want to be sure that the community agrees on it first, but it's a huge milestone.Reviewing Design and Trade-OffsBiri said that the team is reviewing the design choices and trade-offs. The coverage areas include the detailed Leios variant, implementation materials (formal specifications and mini-protocols), trade-offs, potential positive effects on script budgets, and resistance to attacks.He added that the team had planned to submit the PR by the end of August. The draft now includes feedback on failed transactions and aims to have minimal impact on dApps.Community Debates Security, Speed, and DecentralizationNot all community members are convinced that Cardano can achieve higher throughput without compromise. One user questioned whether the network would need to make the same trade-offs as Solana to achieve speed. Biri responded that Cardano deliberately avoided that path, opting for a balance that does not sacrifice decentralization or security. Compromising anything how it would be different from Solana? All these days finger was pointed on them now we also saying we need to compromise. Is Solana understood and solve this problem best way possible much ahead of time?He added that Cardano’s security model limits certain speed optimizations, meaning that matching Solana’s speed would require reducing decentralization, reliability, or cost efficiency. So far, the Cardano community has not been willing to take that approach.Community Approves $71M Funding For UpgradesEarlier this month, the Cardano community approved 96 million ADA (around $71 million) to fund a year-long series of core upgrades. The proposal passed with 74% approval, marking the first time treasury funds have been directly allocated to core development.With these moves, Cardano is taking a major step toward high-throughput, scalable, and community-driven development.FAQsWhat is Cardano’s Ouroboros Leios upgrade? It’s a Cardano Improvement Proposal (CIP) designed to significantly increase network throughput while maintaining decentralization and security, now open for community review. How will Leios improve Cardano’s performance? The upgrade aims to boost transaction throughput and scalability while minimizing impact on dApps and maintaining the network’s security model and decentralization. What areas does the Leios proposal cover? It includes formal specifications, implementation details, script budget improvements, attack resistance measures, and handling of failed transactions.
