Cardano developers merge key Leios code for 15x scaling breakthrough
Current overview (not historical)
Cardano developers merged key Leios code and integrated Praos2 into the main branch, combining the existing consensus protocol with the Leios scaling system to pursue a 15x transaction capacity increase. The merged components include LeiosNotify and LeiosFetch, which facilitate node communication for processing additional transaction batches. The initial rollout targets 13.5 to 22.5 kilobytes per second, with potential later increases to 45–67.5 kilobytes per second. However, the hard fork requires separate approval from delegated representatives controlling 60% of stake, stake-pool operators representing 51%, and two-thirds of the committee.

Report first recorded Oct 26, 19:09
Cardano developers have merged key Leios code into the main development branch, combining the Praos2 consensus protocol with the Leios scaling system to pursue a planned 15-fold increase in transaction capacity. The integration includes LeiosNotify and LeiosFetch components to help nodes process additional transaction batches. IOG estimates the current Ouroboros Praos system handles approximately 4.5 kilobytes of transaction data per second, while the initial Leios rollout targets 13.5 to 22.5 kilobytes per second, with potential to reach 45 to 67.5 kilobytes. Full scaling depends on performance testing and governance approvals.
