Cardano's network moved to version 11 on Saturday through the Van Rossem hard fork. For the first time, the upgrade was approved by a vote of the community, not by the company that built it.
Why the community vote matters
Previous upgrades to Cardano were decided by Input Output Global, the development firm behind the blockchain. This time, holders of the network's native token, ADA, cast votes on whether to adopt the Van Rossem hard fork. The change shifts power from a single company to a decentralized group of users and stakeholders.
The vote itself was conducted on-chain, meaning every ballot was recorded on the blockchain. That makes the process transparent and verifiable. It also means the community now has a direct hand in shaping the network's future.
What the Van Rossem hard fork does
A hard fork is a major software update that requires all nodes to upgrade. The Van Rossem hard fork brings Cardano to version 11. While the specific technical changes weren't detailed in the announcement, the upgrade is part of Cardano's ongoing development roadmap.
The fork is named after Guido van Rossem, the creator of the Python programming language. That's a nod to the network's roots in academic and open-source principles.
How the vote worked
ADA holders could delegate their voting power or vote directly. The proposal needed a certain threshold of support to pass. Once the community approved it, the upgrade was scheduled and executed on Saturday.
This model of governance is often called "on-chain governance." It's a way to let token holders decide on protocol changes without relying on a central authority. Cardano's implementation is one of the first large-scale examples of a blockchain using this approach for a hard fork.
The vote wasn't just symbolic. It had real consequences: the network split from the old version, and all nodes had to update to stay on the correct chain. Those that didn't would be left on a dead fork.
The upgrade went live on Saturday, and the community now holds a direct say in the network's evolution.
