Cardano Targets End-2026 Rollout for Dijkstra Phase 1 Mainnet

Cardano developers are gearing up for the Dijkstra Phase 1 mainnet rollout by the end of 2026. This phase will introduce Linear Leios, a key scaling component, and Nested Transactions to the network's next ledger era.

The roadmap treats Q4 as a code-completion window, while keeping year-end mainnet delivery as the working objective. However, testing, ecosystem readiness, and governance votes could still change the final activation date.

Dijkstra Phase 1 also prepares Cardano for Ouroboros Peras without switching it on immediately. A separate intra-era hard fork is planned for Q2 2027 to add a voting layer for faster chain settlement.
