Cardano Founder Confirms Leios as Solution to Blockchain Trilemma

Cardano founder Charles Hoskinson recently reaffirmed the strategic importance of Leios, a protocol upgrade built over six years to solve the blockchain trilemma of scalability, security, and decentralisation.

In his social media platform X (formerly Twitter) remarks, he noted that Leios remains open source, and its implementation is distinct only to Cardano.

Hoskinson’s confirmation comes on the heels of Cardano’s announcement in October 2024 that the crypto platform squarely aimed its focus to Ouroboros Leios, a highly concentrated directional commitment to network perfection.

Enhancing Security and Finality With Ouroboros Peras

It should be noted that a team of seven was working full time on its development at that time when one could consider such a protocol to be significant for the ecosystem growth. This is based on improvements seen with Ouroboros Peras, a progress on Cardano’s consensus mechanism.

To mitigate this, Peras introduced a voting layer for blocks across the EVM, which drastically reduced the chance of clients successfully rolling back on the subsequently mined block, and this is quite valuable for any partner chain or CEX that needs fast confirmation speeds.

Peras addresses inefficiencies of the older Ouroboros Praos protocol, especially with regard to transaction finality, while Leios takes a more aggressive aim at finding ways to scale up Ouroboros, all the while optimizing for computational efficiency.

Why Leios Stands Apart From Other Blockchain Protocols

Cardano achieved slow performance because its consensus system had to process data between separate blocks. Leios will get rid of these bottlenecks to allow for quicker transaction processing while improving the overall network capacity.

Other key innovations included by Leios are tiered transaction fees that grant users the ability to trade off their transactions versus a risk of spam, and advanced synchronization techniques allowing users to sync nodes with reduced requirement of running every smart contract on the way.

This will make Cardano”s future outlook more optimistic. Still, Hoskinson has affirmed that no other blockchain is using this version of the protocol in an open-source manner.

However, as Leios continues to refine its core infrastructure and test the boundaries of blockchain technology, Cardano remains the only blockchain network using Leios.
