Cardano has activated the Van Rossem hard fork, enabling protocol version 11 and moving the network into its next configuration through an intra-era upgrade that took effect without splitting the chain.

What Changed With Cardano’s Van Rossem Hard Fork
The Van Rossem hard fork is now live on Cardano, advancing the network to protocol version 11. On Cardano, a hard fork of this type is an intra-era upgrade, meaning the network transitions to new protocol rules while remaining a single continuous chain rather than dividing into two.

The change was carried out through the network’s coordinated upgrade process rather than left as a proposal, as detailed in Cardano’s Van Rossem hard fork announcement. The upgrade had earlier been outlined as a proposed intra-era hard fork before reaching activation.
Why Protocol Version 11 Matters for the Cardano Network
Protocol versioning is how Cardano signals network-level updates. Each increment marks a set of consensus and ledger rules that all nodes must adopt, so a move to protocol version 11 represents an agreed upgrade milestone rather than an optional client change.

Because the fork was ratified through Cardano’s on-chain governance framework, the activation reflects the outcome of the community’s decision process tracked among governance action outcomes. That governance layer is the same system that has shaped recent decisions across the ecosystem, including questions raised when Charles Hoskinson addressed Cardano’s treasury and Bitcoin holdings.
What ADA Holders and Market Watchers Should Watch Next
The immediate item to monitor is node operator adoption, since stake pool operators and other node runners need to run software that supports protocol version 11 for the upgraded network to function smoothly.

Ongoing rollout details are being tracked in Intersect’s operational reporting, including the Intersect weekly update for July 17, 2026. Readers should treat the activation itself as confirmed while any downstream functionality or ecosystem effects remain to be observed as tooling and applications adjust.
Security remains a practical watch item for ADA users during any transition period, following incidents such as the Ctrl Wallet shutdown after a Cardano security exploit. For market watchers, the upgrade is a network milestone, not a signal about ADA’s price, which the available research does not address.
