MusashiNet ran for 41 days with 63 pools producing over 127,000 blocks and 30,000 endorser blocks. Leios peaked at 26.8 TxkB/s, six times Cardano's current mainnet ceiling, and carried 54% of chain traffic in stable operation, moving 18x the transaction count of real mainnet traffic. A red team attacked the network without threatening the Praos layer, and the Water phase with a rewards program is live now.

The Leios team completed the Earth phase of MusashiNet, the public testnet, after 41 days that produced over 127,000 blocks and grew participation from three pools to 63. Under synthetic load the network peaked at roughly six times the throughput Praos reaches on mainnet today. The ledger team extended pool distribution with BLS keys, and the Water phase is now open on a fresh chain.

The consensus team released prototype-2026w32, with the node now announcing endorser blocks to peers as a first step toward announcement-based diffusion. Ouroboros-consensus 4.0.0.0 and 4.1 enabled the node to hard fork into the Dijkstra era. The Plutus team opened CIP-0194, CIP-0195 and a new problem statement for community review, and Hydra began rejecting deposits too large to ever be claimed.

The performance and tracing team completed Van Rossem hard fork benchmarks, while the ledger team advanced Dijkstra nested transactions and implemented CIP-50 pledge-leverage-based staking rewards. Hydra released 2.3.0 with a significant snapshot-processing speedup, YAML node configuration, and native HD wallet key support. The developer experience team completed its Community Alignment deliverable with a live ecosystem map, and IO research opened the Cardano Vision '26 Mid-Year report for community feedback.

The consensus team released prototype-2026w29, enabling endorser block certification inside the forging loop to raise throughput, and extended the LeiosNotify mini-protocol toward the full block-announcement flow. Lace 2.2 introduced Bitcoin support for Ledger and Trezor hardware wallets, added SeedSigner air-gapped signing, and published the results of an independent security audit. Plutus implemented the multiIndexArray and policies built-ins from CIP-0156 and CIP-0168, gated behind the Dijkstra era, while Mithril completed IVC SNARK benchmarks and prepared the 2630 distribution.

The ledger team continued Leios integration and implemented CIP-181, removing the DRep-delegation requirement for reward withdrawals. The Lace wallet update introduced in-app swaps, CardanoCube integration, and Ledger and Trezor hardware wallet support. The Mithril team completed its non-recursive SNARK proof refactoring and upgraded the midnight-zk library. An Intersect treasury withdrawal of ₳25.4M was ratified to fund technical stewardship and governance coordination.

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.

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.
