Cardano 1.8.0 delivers new implementations of the core Cardano software components that will enable the Byron reboot. Major improvements have been made to reliability, robustness, and performance while maintaining feature parity with the previous Cardano node and explorer.
Cardano Node 1.8.0
The Cardano node has been completely rewritten using IOHK’s new formal development methodology and rigorously tested using state-of-the-art property-based testing technology. The new network implementation provides enhanced scalability and robustness combined with significantly improved performance which will enable clients to deliver an enhanced user experience. A new command-line interface also makes it easier to operate and control the node directly. The new Cardano Node replaces Cardano SL.
Deployed on mainnet and released March 23, 2020. See the Cardano Node 1.8.0 GitHub release note
Cardano Byron Proxy 1.0.5
The Cardano Byron proxy is a new component that provides chain sync client and server capabilities. It can be used either as a library or as an executable. The executable enables a chain to be downloaded from either a Byron peer or from a new chain sync peer, and also enables a chain to be served using the new chain sync server. The library provides types and definitions that enable this functionality to be embedded within other software.
Deployed and released March 23, 2020. See the Cardano Byron Proxy 1.0.5 Release Notes.
Cardano DB Sync 1.4.0
Cardano DB Sync provides libraries and an executable that allow a PostGreSQL database of blockchain information to be maintained and accessed. Together with Cardano ReST, Cardano DB Sync replaces the Cardano SL Explorer.
Deployed and released March 23, 2020. See the Cardano DB Sync 1.4.0 Release Notes.
Cardano ReST 2.0.0
The Cardano ReST API allows information about the chain that has been stored in the PostGreSQL database to be obtained via a ReST interface. In addition to the Cardano Explorer API end points it includes a new transaction submission API. Together with Cardano DB Sync, Cardano ReST replaces the Cardano SL Explorer.
Released March 24, 2020. See the Cardano ReST 2.0.0 Release Notes
