On July 18, 2026, at 21:44:51 UTC, the Cardano network reached a historic milestone by officially transitioning to version 11 of its protocol through the activation of the Van Rossem hard fork. This event is not just another technical upgrade; it marks the first time in blockchain history that a hard fork was proposed, debated, and 100% ratified through on-chain governance—without requiring intervention or guardianship from Cardano’s founding entities. This massive step for ADA redefines community sovereignty in crypto.
The Voting Figures: The Community Spoke Loud and Clear
To achieve this milestone at network slot 192,844,800, participation numbers reflected overwhelming consensus within the ecosystem:
DReps (Delegated Representatives): Voted in favor with 77.63%, comfortably surpassing the required 60% threshold.
SPOs (Stake Pool Operators): Reached 52.7% support, clearing the 51% bar.
Constitutional Committee: Six of its seven members backed the measure for its final ratification on July 13.
Prior technical preparation matched the challenge. Before activation, over 93% of blocks were produced on the new protocol version, and 84% of exchanges (by liquidity) had fully integrated. Additionally, the dApp/DeFi ecosystem showed 88.3% readiness, ensuring a smooth transition without user disruptions.
Cheaper and Faster Cryptography: The Prelude to Ouroboros Leios
Beyond the political and governance achievement, the Van Rossem hard fork delivers key cryptographic integrity improvements (CIPs) executed on the Plutus smart contract engine:
Contract Optimization: Native array types, support for case expressions, and better multi-asset handling.
Cryptographic Performance: Multi-scalar multiplication over BLS12-381, directly lowering smart contract execution costs.
These optimizations not only make operating on Cardano cheaper and more efficient today, but they also lay the cryptographic groundwork for the upcoming Dijkstra upgrade and the highly anticipated Ouroboros Leios era, which aims to drive network scalability to massive levels.
An Eternal On-Chain Tribute
The upgrade pays an emotional tribute to Max van Rossem, a key pillar in Cardano’s constitutional development who passed away in October 2025. By naming this historic transition in his honor, the ecosystem immortalized Max’s legacy directly into the blockchain’s ledger.
Market Impact: What to Expect in the Short Term?
The successful activation of the Van Rossem hard fork eliminates one of the biggest fears among investors: governance paralysis. Cardano demonstrated that its on-chain voting mechanisms work at scale without breaking the network. In the short to medium term, lower costs on Plutus could attract a new wave of DeFi developers, strengthening ADA’s fundamental market value.
