Intersect’s Hard Fork Working Group has proposed to name the next Cardano hard fork to Protocol Version 11, the “van Rossem” hard fork, after DRep Max van Rossem. The community has a tradition of naming hard forks in memory of impactful DReps in the blockchain ecosystem, starting with Byron.
Cardano said naming the 2026 hard fork after van Rossem will continue to uphold a long-standing tradition that has been passed down from Shelley, Allegra, Mary, Alonzo, Vasil, Valentine, Chang, and Plomin. The Vasil, Chang, and <a href="https://www.cryptopolitan.com/cardano-ada-advances-with-plomin-hard-fork/" rel="noopener noreferrer nofollow">Plomin</a> hard forks were named after the recently deceased Dreps, in recognition of their families and the Cardano community as a whole.&nbsp;
Meanwhile, the Hard Fork Working Group said the Cardano community remembers Max as a sharp-minded and deeply committed DRep, as those who worked with him attest. He was heavily involved in the development of Cardano’s constitution and contributed to many governance discussions that have helped shape and optimize the network.&nbsp;

DRep van Rossen <a href="https://gov.tools/governance_actions/8845bfc37bb2f69e8f200fe28148b3dea3c4399b0c49ee0ed2bb4e349cab9eb7#0" rel="noopener noreferrer nofollow" target="_blank">served</a> as both a member and a co-lead of the Constitutional Committee Election Working Group, which oversaw the first fully elected Constitutional Committee (CC). He was also integral in the network’s founding governance documents as a delegate representing the Dutch Cardano community at the Constitutional Convention in Buenos Aires, Brazil. Max is one of the major driving forces behind the inclusion of Article VIII in the Cardano constitution.&nbsp;
Additionally, Max founded AdaMoments, a project that allowed Ada holders to preserve their personal histories by storing images, videos, and text as permanent moments on the Cardano ecosystem. He also facilitated meetups and connected people across the Cardano blockchain as a member of the Dutch community.&nbsp;
Meanwhile, Intersect announced the proposed hard fork to Protocol Version 11 late last year. The upgrade is expected to introduce improvements to node security, ledger consistency, and Plutus’s performance without requiring a transition to a new ledger era. These updates will include enhancements to reference input rules, the uniqueness of the VRF key, and Plutus primitives. The changes represent the next tranche of treasury-funded development for the Cardano ecosystem.

The Hard Fork Working Group has <a href="https://cardanoscan.io/govAction/gov_action13pzmlsmmktmfareqpl3gzj9nm63ugwvmp3y7urkjhd8rf89tn6msq95mp3f?tab=votes" rel="noopener noreferrer nofollow" target="_blank">launched</a> a poll where Cardano community members will vote on the proposed name for the hard fork. The poll will run from January 13 to February 14, 2026. Participating DReps are required to deposit a minimum of 100,000 ADA to vote, and so far, eight DReps have voted YES, representing 1.57% (91.24M ADA) of the total stake (14.16B ADA). The last vote was cast over 20 minutes ago as of publication.
Meanwhile, the final vote will be forwarded to the Technical Steering Committee (TSC) for review and ratification. The hard fork working group will also form a think tank and meet fortnightly to discuss and coordinate matters related to the hard fork. The upcoming hard fork requires network-wide coordination, but with a much lower integration burden than during era transitions.
All other hard fork-related information will be communicated later through the Intersect Knowledge Base. An open Intersect working group will also be formed to include community members who want to participate in the current and future mainnet hard forks.&nbsp;
The latest proposed upgrade will introduce improvements without transitioning into a new ledger era, keeping Cardano within the same ledger era, currently Conway. The intra-era hard fork introduces fixes, refinements, optimizations, and other new features that do not require an era transition.&nbsp;&nbsp;
These new changes will collectively enhance script performance, reduce execution costs, and expand the capabilities of builders within the Cardano network. They will also improve governance correctness and transparency.
