II. What Actually Changes With Van Rossem

Cardano is entering a new stage in its development, and the Van Rossem hard fork is one of the clearest signs of that. For the first time in Cardano’s history, a protocol upgrade is being activated completely through onchain governance.

That means the network is no longer relying on a single body to schedule and execute major upgrades. Instead, the process now involves stake pool operators, delegated representatives known as DReps, and the Constitution Committee working together through Cardano’s governance system.

The hard fork is named after Max van Rossem, a respected Dutch member of the Cardano community who contributed heavily to governance development before his passing.

Naming protocol upgrades after important contributors has become part of Cardano’s tradition. Earlier examples include Vasil, Chang, and Plomin. The Van Rossem hard fork ensures that developers and infrastructure providers do not need to completely rebuild their applications or integrations.

Wallets, exchanges, indexers, and decentralized applications can continue operating without major architectural changes. The upgrade improves performance, efficiency, and network reliability, while also lowering smart contract execution costs by around 10 percent on average.

III. Ecosystem Readiness

Beyond the immediate improvements, Van Rossem also helps prepare Cardano for much larger developments expected later in 2026. One of those developments is Ouroboros Leios, Cardano’s major scaling upgrade.

Leios is designed to dramatically increase throughput by separating transaction processing into multipleparallel layers. While Van Rossem itself does not deliver major throughput gains, it helps prepare the infrastructure and tooling needed for future scaling.

Leios is expected to target throughput levels far beyond Cardano’s current capacity, potentially reaching thousands of transactions per second under certain conditions. However, these improvements are tied to future protocol upgrades, not directly to Protocol Version 11.

Cardano’s broader ecosystem is also evolving around artificial intelligence, decentralized storage, and oracle infrastructure. Integrations with Filecoin, Pyth, and AI-focused payment systems show that the network is increasingly positioning itself as infrastructure for more than just payments or decentralized finance.

Cardano also maintains one of the strongest reliability records among major blockchains. Since launch, the blockchain has never experienced a complete mainnet outage. For the first time, Cardano is showing that a public blockchain can coordinate a major protocol upgrade through constitutional rules, public voting, and decentralized participation rather than through a central authority making the final decision alone.

If the late June 2026 rollout succeeds smoothly, Cardano will have demonstrated the ability to evolve at scale while letting governance happen directly on-chain.

IV. The Road Ahead

Beyond preparing the network for Protocol Version 11, the Daedalus 11.0.0 release also reflects a broader shift in how the wallet evolves alongside Cardano itself. The update is not focused on redesigning the user experience or introducing flashy new wallet features.

Instead, it focuses on ensuring long-term compatibility, stability, and infrastructure readiness as Cardano enters a new governance era. The release bundles Cardano Node 11.0.1 directly into the wallet, aligning Daedalus more closely with the network’s protocol evolution and future upgrade cycle.

This approach reinforces Daedalus’ role as more than just a desktop wallet. As a full node wallet, it continues to prioritize security, self-custody, and direct participation in the network rather than prioritizing lightweight convenience.

The update also signals that future versions of Daedalus will likely evolve in parallel with major protocol upgrades, making the wallet an increasingly important gateway for users who want to interact directly with Cardano’s decentralized infrastructure and governance systems.
