What happened.

Crypto.News reported that Cardano’s Dijkstra roadmap targets Linear Leios in Phase 1 around Q4 2026. The same report places Peras in a separate hard fork in Q2 2027.

The new information is the reported quarterly framing and the separation of Peras into its own hard-fork step. The record characterizes Leios as throughput work and Peras as work related to faster settlement or finality.

Why it matters.

If these targets hold, they offer a provisional planning anchor for SPOs, builders, and holders. The reported sequence would also imply two node-upgrade windows within roughly nine months.

That framing may help distinguish the two reported protocol tracks: Linear Leios first, followed by Peras through a separate hard fork. It does not establish that either rollout is scheduled.

What to watch next.

The most useful receipt would be an official IOG or Intersect statement confirming the roadmap timing, or an on-chain governance action tied to these changes. A fixed hard-fork date, a CIP, or a governance-action ID is not established in the supplied record.

Until such evidence appears, the reported quarters should be treated as discovery-only targets rather than release commitments. Roadmap dates can slip.

What to watch

Watch for an official IOG or Intersect statement, or an on-chain governance action, that confirms or revises the reported Q4 2026 and Q2 2027 targets.
