Cardano advances with van Rossem hard fork, eyes Dijkstra era

Cardano has submitted the van Rossem hard fork governance action, introducing new features and preparing for the Dijkstra era and Leios scalability. This follows extensive testing and a Plutus Cost Model update.

Cardano has achieved a major milestone with the submission of the van Rossem hard fork initiation governance action on its mainnet. This intra-era hard fork introduces new features and sets the stage for the upcoming Dijkstra era, which is expected to deliver the Leios scalability solution to the network. The van Rossem upgrade follows thorough testing and governance activities on the Preview and Preprod test networks during May and June 2026. Notably, the process included an update to the Plutus Cost Model parameters, ratified on June 13 and scheduled for enactment on June 18, 2026. The proposal for the van Rossem hard fork activation carries a final expiration deadline of July 18, 2026. These advancements represent a pivotal step in Cardano's technical roadmap, aiming to boost scalability and operational capabilities while minimizing disruption. The upgrade is designed to maintain Cardano’s innovative edge and prepare the network for future growth and advanced feature integration.
