Cardano successfully activated the Van Rossem hard fork on July 18, 2026, marking a historic shift in how the network operates. For the first time in Cardano's history, the upgrade was proposed, debated and ratified entirely through the network's onchain governance system, rather than being coordinated by founding developer Input Output. This represents a fundamental change in Cardano's governance structure, with the upgrade moving the mainnet to Protocol Version 11 after governance approval moved the upgrade forward. The Cardanoscan governance record shows that the proposal called for Protocol Version 11, with 77.63% DRep support and 52.7% SPO support when required thresholds were met. The upgrade went live around 21:45 UTC and caused only a brief ten-minute block gap with no disruption to users or holdings.
The ratification process demonstrated the network's new decentralized governance capabilities, with delegated representatives voting 78.97% in favor against a 60% threshold requirement. The constitutional committee, comprising seven elected members, found the hard fork compliant with all seven members agreeing where five were required. Interestingly, stake pool operators approved the community's first self-directed hard fork by the narrowest of its three margins, with 53.02% of operators voting to approve the upgrade. Under Cardano's constitution, the upgrade required at least 85% of stake pools by active stake to run compatible node software before ratification, but network telemetry showed adoption well ahead of that requirement, with roughly 93% of block production already on version 11 heading into activation. The upgrade also required sign-off from three separate bodies, demonstrating the network's commitment to democratic governance.
Version 11 introduces significant technical improvements while maintaining user experience continuity. The upgrade is an intra-era hard fork, so Cardano remains within the Conway era while updating parts of its protocol. It adds new capabilities to Plutus, the platform developers use to write Cardano's smart contracts, unifying the built-in functions available across the platform's three versions so older applications gain newer features. The upgrade also tightens several of the ledger's validation rules, including one guaranteeing that no two stake pools can reuse the same cryptographic identity key. For users, there are no visible changes for casual ADA holders - transactions work the same way, wallets don't need updating, and fee structures remain unchanged. However, the Plutus changes lower the costs of running smart contracts from DeFi protocols to NFT marketplaces, with cheaper execution enabling developers to charge less per transaction, though savings are not automatic as developers must rebuild their contracts to capture the benefits.
Cardano has demonstrated strong momentum following the Van Rossem upgrade, with the token surging 9.3% to an intraday high of $0.176 after clearing the $0.166 resistance that had capped several recovery attempts during July. According to crypto.news data, ADA traded near $0.1745 at press time on July 21, with the token forming a 4-hour rounding bottom structure from the July 13 low near $0.155. The structure places the neckline at $0.20, where ADA reached a local high in early July, with a sustained break above $0.18 putting $0.20 within reach for a potential 14.6% gain. Technical indicators show buying pressure strengthening on the 4-hour timeframe, with the MACD line at 0.0022 above its signal line and Chaikin Money Flow remaining above zero at 0.11, confirming net capital entry during the recovery. However, the Stochastic RSI at 81.38 has entered overbought territory, while ADX sits at only 15.24 indicating ADA has not yet established a powerful directional trend despite the sharp intraday gains.
The Van Rossem upgrade establishes procedural groundwork for Cardano's future scaling initiatives. As Input Output confirmed, the upgrade lays the foundation for the next upgrade, the Dijkstra era hard fork, which will introduce Ouroboros Leios to Cardano. Ouroboros Leios is a scaling proposal for Cardano's proof-of-stake consensus model, expected later in 2026 and aimed at sharply increasing transactions per second without weakening the protocol's security guarantees. The upgrade represents the first major upgrade fully approved through Cardano's Voltaire governance system, with the same system also producing different outcomes for funding proposals. This procedural shift means that Cardano can now upgrade itself by vote, fundamentally changing who controls protocol changes and moving away from the founding company's top-down approach. The biggest difference between the models lies in their approach - DeepSeek places far more emphasis on upcoming catalysts and ecosystem developments, while Grok looks for confirmation first through existing price trends and resistance levels.
