The Hydra team moved its specification to Typst, formalized it in Agda, and published native Linux ARM64 node images alongside AMD64, with faster Blockfrost query caching. The research team held its second Cardano Vision 26 workshop, covering data availability requirements and specifications.

Records stay on a permissioned network and only their cryptographic proof reaches Cardano, so auditors can confirm a record is genuine without seeing the underlying data. Engineering work cut the cost per record by 92 percent, and contracts cover 6.5 million records through 2030.

The Plutus team published release 1.68.0.0 with Plutus V4 ledger API types, cardano-init reached its first tagged releases, and Hydra moved persisted event payloads to CBOR, shrinking a three-node benchmark database by more than half. Plinth also gained a one-command install script.

Adding a dependency, writing a test and calling a REST endpoint cover most of what is needed, while the extended UTXO model and validator scripts can be learned gradually alongside. The post also previews three experimental Java projects now in development.

The three-month student project produced an analysis of global sustainability regulation, a scorecard for assessing networks against reporting requirements, and a scoped pilot business case showing measurable return on investment. The team also mapped how much regulatory pressure companies face in each region.

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.

Two on-chain votes needed action from DReps and stake pool operators before September 1, among them the 2026 Constitutional Committee update. A new Project Catalyst pilot awards grants of up to 200,000 ada based on real-world usage.

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.

Users can highlight a precise passage of the Constitution, submit a Constitutional Amendment Proposal or raise an issue, and follow each proposal through its lifecycle. Wallet connection uses a stake address as identity, with no account, email, or password required.

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.

Ratification requires support from both DReps and stake pool operators. The lower fixed fee gives small pools breathing room as block rewards decline, while the completed memory increase eases contract deployment for developers.

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 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.

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.
