- Leios is exclusive to Cardano to tackle scalability, security, and decentralization.
- Hoskinson revealed that resources were reallocated to Leios, with 6.8 FTEs working on its rapid development.
- Leios builds on Ouroboros Peras, which introduced a voting layer for faster transaction settlement.
Cardano founder Charles Hoskinson has reaffirmed that Leios – a significant protocol upgrade developed over six years specifically for Cardano – represents the network’s current answer to the blockchain trilemma: balancing scalability, security, and decentralization.
Responding to questions on X (formerly Twitter) about potential adoption by other chains, Hoskinson clarified that while Leios is open-source, it remains uniquely implemented on Cardano for now.
Cardano’s Strategic Focus on Leios Development
This confirmation aligns with an earlier announcement from October 2024, when Hoskinson revealed Cardano had shifted resources specifically toward Ouroboros Leios.
At that time, the project had nearly seven full-time employees dedicated to its development, underscoring its strategic importance.
Leios Builds on the Momentum of Ouroboros Peras
The shift to Leios came after substantial progress on Ouroboros Peras, an enhancement to Cardano’s consensus protocol. Peras introduced a voting layer that enables faster transaction finality, reducing the risk of block rollbacks.
This feature is particularly beneficial for use cases requiring quick confirmation, such as partner chains and centralized exchanges.

Peras addressed inefficiencies found in the earlier Ouroboros Praos protocol related to how long transactions took to be considered final, thereby boosting security and efficiency within Cardano’s decentralized framework.
Leios Upgrade Targets Scalability and Network Efficiency
While building on Peras, Leios pivots its focus heavily toward improving scalability and computational efficiency. Earlier Cardano protocols, including Praos, encountered throughput limitations due to specific data and communication dependencies between blocks. Leios is architected to eliminate these bottlenecks, which enables faster transaction processing and greater overall network capacity.

Key advancements introduced by Leios include tiered transaction fees, allowing users choice regarding priority, and enhanced chain synchronization methods that reduce the need to execute every smart contract during the node syncing process.
Although the Leios protocol code is open-source, Hoskinson’s recent statements underscore that no other blockchain currently utilizes this specific implementation. For the present, Cardano remains the exclusive home for this significant protocol advancement as the network continues to evolve its core technology.
