Cardano Sets Two-Phase Dijkstra Scaling Roadmap For Leios Era

Trusted Editorial content, reviewed by leading industry experts and seasoned editors. Ad Disclosure Cardano’s development roadmap for its Dijkstra-era scaling work has been structured around a two-phase rollout, with Ouroboros Leios and related throughput improvements central to the plan. The first phase, involving Linear Leios and nested transactions, targets code completion in the fourth quarter of 2026. A second phase, involving Ouroboros Peras, is planned for the second quarter of 2027. This is a roadmap story, not an adoption victory lap. Cardano has long talked about scaling toward much larger user numbers, but those goals remain future ambitions. The important news here is the technical path being mapped, not proof that one billion users have arrived. TL;DR Cardano’s Dijkstra-era roadmap includes a two-phase scaling plan. Phase 1 targets Linear Leios and nested transactions in Q4 2026. Phase 2, involving Ouroboros Peras, is planned for Q2 2027. Why The Dijkstra Era Matters Cardano’s development style is different from many other chains. The network often moves through research-heavy phases with formal naming, peer-reviewed design, and staged implementation. That can make pro...
