Cardano Foundation (CF) has announced the release of Cardano Rosetta Java v2.0.0, a backend infrastructure upgrade for the Cardano (ADA) network. The update is designed to standardize blockchain data access to the Rosetta API and was shared with the broader community via the Cardano Foundation’s X page.
The upgrade aims to enable seamless integrations for exchanges and wallets without custom coding. Cardano Rosetta Java v2.0.0 is also intended to deliver faster synchronization times for exchanges, which reportedly fell from approximately 52 hours to 37 hours.
That change corresponds to about 30% faster syncing, which the foundation says should reduce downtime and support quicker recovery.
Faster synchronization is particularly relevant when an exchange needs to onboard Cardano or when a service must resync from scratch. The foundation also highlighted that faster recovery becomes critical when infrastructure goes down.
Cardano Rosetta Java v2.0.0 is described as providing more reliable and future-proof infrastructure. Key upgrades include newer Cardano nodes (v10.5.x), with Ouroboros Genesis support intended to improve security and long-term scalability.
The Mithril upgrade is also cited as part of the update, with the goal of enabling faster and safer blockchain data verification and reducing the risk of edge-case failures on the blockchain.
The release is now live and introduces major upgrades to Cardano’s exchange integration stack.
The foundation said the update also supports a cleaner, more modular system that is easier to extend, which it described as important for future Cardano features and scaling plans.
Developers are also reminded to adjust their setup to meet the upgrade requirements. A significant change noted in the announcement is that anyone upgrading must resync from “genesis.” While described as painful in the short term, the foundation said it should help ensure clean and consistent data.
In addition, operators are required to use Docker Compose or Kubernetes/Helm charts, rather than relying on “one-click” Docker containers.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
