The van Rossem hard fork upgrade for the Cardano Mainnet has officially commenced. The process coordinates two distinct governance actions: a Plutus Cost Model parameter update (enacted on June 18) and the hard fork initiation action (submitted on June 16). Following successful testing on the Preview and Preprod testnets, the final decision to ratify and execute the upgrade now rests entirely with the on-chain governance bodies (DReps, SPOs, and the Constitutional Committee).

The High Assurance team launched a smart contract testing beta tool, while the Mithril team completed its SNARK-friendly genesis certificate and optimized recursive scaling primitives. Under Voltaire, a critical call for candidates was issued for the upcoming Constitutional Committee election to ensure a competitive process. Finally, the Research team had its Cardano Vision 2026 proposal officially ratified by the community with 74.96% DRep approval.

The Cardano Foundation, EMURGO, and Rare Network shared results from their year-long Unified Global Events Marketing Strategy. Funded by the Treasury, this joint initiative boosted Cardano's brand awareness at 20 global tech conferences using a single, cohesive message. The campaign provided a promotional platform for 76 ecosystem projects, engaged over 7,500 participants (including a strong developer turnout), and initiated high-level institutional discussions with entities like the London Stock Exchange Group (LSEG).

The Cardano Budget Process has commenced voting on the Hydra platform to fund core usability and security infrastructure. Meanwhile, the Van Rossem hard fork (Protocol Version 11) successfully launched on the PreProd testnet, marking the final checkpoint before mainnet deployment. New CIP updates introduced variable deposits for stake pool pledges and Hydra-powered L2 voting, while the Cardano Foundation announced a three-year partnership with the Brazilian Olympic Committee and published an agricultural tracking case study in India.

The CCI V2 Roundtable Talk gathers Pentad representatives to review a joint proposal focused strictly on maintaining critical core infrastructure and establishing an upgrade framework. The session covers the role of the new Steering Committee, treasury oversight, and how operational choices were prioritized. Notably, the proposal excludes funding for DApps, liquidity, or marketing, and serves as an objective, auto-dubbed review rather than a promotional event.

The LayerZero integration connects Cardano to the wider crypto economy, enabling over 800 tokens to move natively onto the network. These assets will benefit from Cardano's built-in ledger security and deterministic smart contracts. The rollout will proceed in phases through 2026 launching endpoints, the Stargate liquidity layer, and developer tools with the goal of supporting any asset by year-end.

The Cardano Accelerator Program (CAP) is inviting subject matter experts to join its mentor network for the Fall 2026 cohort, themed Real-World Trust. Mentors will provide flexible, one-on-one guidance to startups focused on identity, traceability, and digital passports. This non-commercial engagement offers industry experts ecosystem-wide visibility in exchange for mentoring in strategy, compliance, or fundraising. Applications opened on June 5, 2026, for a one-month window.

The consensus team advanced the Leios prototype toward the Dijkstra era and finalized the certificate size reduction to 200 bytes. In wallets, Lace 2.0.6 went live, fixing DRep ID message signing for mnemonic wallets and adopting the CIP-129 format. For scaling, Hydra merged its partial fanout feature to eliminate the UTXO limit per head, while Mithril completed circuit key caching for its SNARK library.

The Ouroboros Leios architecture solves the blockchain trilemma by decoupling transaction diffusion from sequencing. This setup integrates advanced cryptography, including SNARKs for sublinear correctness verification, Data Availability Sampling (DAS) to verify blocks without full downloads, and Bloom filters to check data relevance. Finally, UTXO sharding distributes state maintenance across the network, enabling true horizontal scalability so that consumer-grade hardware nodes can participate securely without processing the entire blockchain.

Intersect is facilitating the election process for Cardano’s Constitutional Committee to fulfill a critical "unowned function" required by Section 3.2 of the Cardano Constitution. Because a fair election requires a structurally neutral administrator, Intersect has stepped in as a non-partisan steward rather than a participant, leveraging its established institutional knowledge in managing member-driven governance. This independent, non-commercial coordination ensures that the committee can be updated efficiently without stalling Cardano's overall governance framework.
