The consensus team stabilized the Leios testnet with two prototype builds and a voting dashboard for endorser block observability. The High Assurance team shipped the Plinth Static Analyzer on the Visual Studio Marketplace and a JSON-RPC backend for property-based testing. Mithril completed the SNARK recursive circuit modularity work and upgraded the midnight-zk library. Under Voltaire, the van Rossem hard fork passed ratification and will enact at the next epoch boundary, advancing Plutus ahead of the Dijkstra era that introduces Ouroboros Leios. The research team published the Cardano Vision 2026 Mid-Year Progress and Transparency Report draft for community feedback.

Cardano's Plutus Core ships first-class built-in primitives for the pairing-friendly BLS12-381 elliptic curve, exposing scalar multiplication, point addition, hash-to-curve, and pairing checks that any Plutus or Aiken script can run natively without external services or trusted oracles. The article walks through the curve and the Aiken API, then builds four concrete protocols on top of those primitives: BLS signature aggregation and multi-sig, key derivation from passwords and seeds, verifiable random functions for privacy and leader selection, and BBS+ signatures for anonymous credentials with selective disclosure. A follow-up will compose the same primitives into zk-SNARKs and polynomial commitment schemes.

Input Output's Cyclic Atomic N-party Swap (CANS) protocol arranges participants in a ring where each sends assets once and receives once, with the entire swap enforced as atomic: either everyone gets what they agreed to, or nobody loses anything. The design removes the need for bridges, wrapped tokens, or trusted intermediaries by making signatures conditionally valid behind a shared secret revealed only once every party has locked funds. A reference implementation in Rust, formally verified with up to 20 concurrent parties, shows the approach works in practice today, and any chain with native or verifiable Schnorr signatures can join a swap session.

A Cardano Community roundtable hosted three Constitutional Committee candidates to discuss what serving on the Committee involves as the 2026 election gets underway. Moderated by the Cardano Foundation governance lead, the session moved past a traditional candidate introduction to examine the practical realities of the role, including workload, transparency, constitutional interpretation, collaboration, and Committee fatigue. Candidates also addressed whether the current incentive model is sufficient to sustain long-term participation, giving DReps and observers a fuller view of the responsibilities and challenges ahead of the vote.

Learn Cardano's latest episode covers AlphaGrowth's on-chain Cardano PRIME proposal, a 120 million ada DeFi growth request, governance debate around the net change limit, Ethereum research into native UTXOs, RealFi's testnet launch, SecondFi recovery guidance, and EMURGO stepping down from the Pentad while recovery work continues.

The performance and tracing team removed the legacy iohk-monitoring tracing backend (roughly 11,000 lines) and RTView from cardano-tracer, while the ledger team extended StAnnTx memoization to Alonzo and merged the first Leios-related changes. In wallets, Lace released browser extension 2.1, headlined by a wallet security check feature. Under Voltaire, DRep voting is underway in the Constitutional Committee election ahead of the July 23 deadline, and the Research team advanced its Cardano Vision 2026 workstreams with the first zero-knowledge technical workshop.

Applications are open for Draper University's Genesis Hacker House, a four week Silicon Valley residency for early stage teams building on Cardano, while Arouet Holdings is seeking candidates for its voluntary Community Director board role. The State of Cardano Governance 2026 report examines DRep participation, voting power concentration, and SPO engagement, with six recommendations to strengthen governance. RealFi launched its Phase 1 testnet, opening swap, stake, and unstake actions for its stablecoin based credit protocol, and several Cardano Improvement Proposals advanced through active review, including Proof of Existence metadata and DRep voting power concentration.

Learn Cardano examines the SecondFi asset recovery checker and its 16 million ada recovery fund, the precautionary pause on Midnight Glacier Drop redemptions, and how the Open USD stablecoin standard connects to Cardano through Brale. The episode also explores the proposed 500 million ada net change limit and what treasury funding means for DeFi and infrastructure growth.

The Cardano Foundation has partnered with SENAI São Paulo to drive blockchain adoption across Brazilian industry. This collaboration introduces specialized training, educator certification programs, and executive education. It also launches practical, real-world industrial pilots, including Digital Product Passports, after an initial technical immersion successfully onboarded 130 research and education specialists.

The latest ecosystem updates highlight the launch of the Ouroboros Leios testnet (Musashi Dojo), introducing parallel "endorser blocks" to potentially scale network throughput from 4.5 KB/s up to 200 KB/s. Additionally, applications open next week for the $80M Draper Dragon Orion Fund startup cohort and a voluntary Community Director seat on the Arouet Holdings board. Other major highlights include Pyth Network oracles going live on Cardano and the Cardano Foundation's inclusion in Fortune's Crypto Innovators 2026 list.
