Cardano van Rossem Hard Fork Advances as DRep Vote Clears Threshold and Exchange Readiness Hits 77%

Meta Description: Cardano’s van Rossem hard fork advanced as DRep approval reached 62.76%, node v11 block production hit 87%, and exchange readiness rose to 77.37%.

Cardano’s next protocol upgrade moved closer after governance support for the van Rossem hard fork crossed a key threshold and ecosystem readiness improved. According to Intersect, a member-based organization for the Cardano ecosystem, DRep approval for the initiation action reached 62.76%, multiple major exchanges indicated readiness that lifted liquidity coverage to 77.37%, and block production on node version 11 climbed to 87% in epoch 639. These developments put critical ratification and enactment dates squarely in focus for traders tracking the upgrade timeline.

What Happened

The van Rossem hard fork initiation governance action was submitted on Cardano Mainnet on June 16 during epoch 637, beginning the on-chain governance process for an intra-era upgrade. Intersect reported that ecosystem readiness “made significant progress this week.” For stake pool operators (SPOs), block production on node version 11 remained stable and ticked up to 87% for epoch 639. On the market infrastructure side, multiple major exchanges signaled readiness, pushing readiness by liquidity to 77.37%.

On governance, current voting stands at 62.76% DRep approval, 31.59% SPO approval, and 1 constitutional vote from the Constitutional Committee (CC), with 6 members yet to vote. The DRep threshold of 60% has been surpassed. The SPO vote has not yet met the 51% threshold. The CC requires 5 out of 7 votes; with one recorded, four additional CC votes remain to reach that mark.

Based on the governance timeline shared in the update, current progress points to potential ratification within the next two epochs. The next possible ratification dates are June 28 or July 3. If ratified on those dates, corresponding potential enactment dates would be July 3 or July 8, respectively.

Market Reaction

The update focuses on governance and technical readiness metrics and does not include immediate market price or volume data. Traders and market makers following Cardano’s upgrade schedule are likely to focus on the posted thresholds, exchange readiness by liquidity at 77.37%, and the forthcoming ratification and enactment windows as practical markers for near-term positioning.

In the absence of price figures in the update, the near-term calendar—possible ratification on June 28 or July 3 and potential enactment on July 3 or July 8—serves as the primary catalyst map for participants tracking timing risk around the van Rossem hard fork.

Trading and On-Chain Activity

The most immediate on-chain signal in the update is the share of block production on node version 11, which remained stable and increased slightly to 87% for epoch 639. That figure, alongside the 77.37% readiness by liquidity, underscores steady alignment across core infrastructure and venues as the governance process moves forward.

Voting remains the gating variable. DRep approval at 62.76% has cleared the stated 60% threshold, while SPO approval at 31.59% is below the required 51%. The CC has registered one vote, with six members yet to vote as the committee works toward a 5-of-7 requirement. Together, these datapoints map the remaining steps needed to ratify and enact the upgrade on the dates noted in the timeline.

Why This Matters Now

Intersect’s update places concrete numbers and dates around the van Rossem hard fork, giving a clearer sense of how close Cardano is to its next intra-era upgrade. The DRep threshold being met removes one major hurdle. The SPO and CC votes, along with sustained infrastructure readiness—highlighted by 87% block production on node v11 and exchanges covering 77.37% of liquidity—frame what needs to happen next and when it could happen.

For traders and validators, the combination of governance progress and operational readiness translates into a more defined timeline. Possible ratification on June 28 or July 3 and potential enactment on July 3 or July 8 channel attention to specific windows where execution risk and network changes could intersect with market positioning and operational planning.

Broader Market Context

The governance momentum arrives alongside several ecosystem initiatives. The public testnet for Ouroboros Leios, known as Musashi Dojo, launched this week. Leios is described as a scaling solution for Cardano; a year ago it existed as a research paper from Input Output (IO) Research, and its next phase has now been unveiled as a live prototype on a public testnet. In parallel, Mithril is moving into its next phase as Teragone takes over the workstream, bringing deep cryptography expertise and continuity coordinated through Intersect. The RealFi Phase 1 Testnet is expected to go live on July 6, marking the first public step toward next-generation stablecoin infrastructure on Cardano.

Taken together, the hard fork’s governance progress, the Leios testnet, the transition in Mithril’s workstream, and the approaching RealFi testnet date suggest an active build cadence across scaling, governance, and stablecoin primitives, with concrete milestones and dates set out in the latest update.

Implications for Investors and Traders

The datapoints in the update outline a straightforward checklist:

• Governance thresholds: DRep approval at 62.76% has cleared the required 60%; SPO approval at 31.59% remains below the 51% threshold; the CC has one vote recorded with six members yet to vote toward a 5-of-7 requirement.
• Operational readiness: Block production on node version 11 at 87% in epoch 639 signals broad validator alignment; exchange readiness by liquidity at 77.37% indicates deeper venue coverage for the upgrade window.
• Calendar catalysts: Possible ratification on June 28 or July 3; potential enactment on July 3 or July 8; RealFi Phase 1 Testnet expected July 6.

Positioning strategies around these dates will likely hinge on how quickly SPO approval approaches the 51% threshold and how the CC vote count progresses. Infrastructure indicators—node v11 block production and exchange readiness—are already trending in the right direction in this update, giving traders clearer operational context as governance advances.

What’s Next

Based on the governance timeline included in the update, current voting progress indicates a potential ratification within the next two epochs. The next possible ratification dates are June 28 or July 3, with the corresponding potential enactment dates being July 3 or July 8. In the interim, the focus will remain on whether SPO approval rises toward the 51% threshold and how quickly the CC moves toward its 5-of-7 requirement.

On the development front, Musashi Dojo—the public testnet for Ouroboros Leios—has gone live, while Mithril advances under Teragone’s stewardship via Intersect. The RealFi Phase 1 Testnet is expected to begin on July 6, billed as the first public step toward next-generation stablecoin infrastructure on Cardano. These milestones, together with the van Rossem hard fork’s governance path, frame a busy near-term roadmap for the network.
