#cardano将于7月18日硬分叉升级 Cardano will activate the van Rossem intra-era hard fork (protocol upgraded to v11) on July 18, 2026 (or near the epoch boundary). This is a technical optimization upgrade within the Conway era, not a switch to a new epoch. The governance action was submitted on June 16. As of now, the DRep support rate is above 75% (threshold 60%), SPOs are above 52% (threshold 51%), and the Constitutional Committee (CC) has confirmed constitutionality with 4 votes—only 1 vote away from formal approval. If ratification passes on July 13, enactment can occur on July 18.
Core improvements
Plutus smart contract optimizations: Adds multiple CIP primitives (e.g., CIP-0109, 0132, etc.), unifies built-in function availability across V1/V2/V3, and supports “case” expressions for Bool/Integer/Data types—greatly improving script performance and code conciseness.
Ledger and node enhancements: Enforces stronger VRF key-hash uniqueness, revises reference input rules, applies governance voting limits on-chain, and enables better error reporting, improving stability and scalability. No interruption compatibility: Keeps the Conway era. The node 9.x series is widely deployed; 90%+ of blocks are produced by v11-ready nodes. Exchanges, wallets, and DApps are all more than 80–90% ready.
Meaning and impact: This is a routine upgrade after Cardano governance has matured. The focus is to strengthen developer experience and contract efficiency, paving the way for future initiatives such as Leios (parallel scaling). It does not involve major changes to inflation, staking, or governance mechanisms. There is no direct dilution or forced action for ADA holders. Historical hard-fork experiences suggest such upgrades usually boost sentiment in the short term, but potential small fluctuations after activation should be watched. Risk points: If the CC’s final vote is delayed, it could be pushed to July 23. Also, it may block other funding proposals on the same day. Overall preparation is strong: the community and the Intersect working group are highly coordinated, with a very high success rate.
Summary: Van Rossem is a pragmatic step for Cardano toward a more efficient, scalable Layer 1, strengthening Plutus competitiveness. In the short term, the rollout may boost market confidence; in the long term, it benefits ecosystem development and adoption. Recommendation: follow official Intersect announcements and keep your nodes/wallets updated before and after the upgrade. Cardano’s governance model is gradually maturing, and events like this will become the norm. Invest carefully—DYOR.
