Cardano completes van Rossem upgrade and outlines Dijkstra hard fork roadmap with Ouroboros Leios, Nested Transactions, and Linear Leios targeting end of 2026.
Regulation & Gov ·
Cardano activated its van Rossem hard fork, upgrading the mainnet to Protocol Version 11 to lower smart contract execution costs and prepare for the Dijkstra hard fork targeting late 2026. The Dijkstra upgrade will introduce Ouroboros Leios, a scaling proposal designed to increase transaction throughput without weakening Cardano's proof-of-stake security. The van Rossem hard fork marks the first governance-driven upgrade in Cardano's history, with voting on committee elections currently underway.
