Cardano DB Sync 1.4.0

on GitHub

The Cardano DB Sync component (cardano-db-sync) synchronises chain data into a relational database.

Previously this component was released as part of the Cardano Explorer backend. In this release it has been renamed and moved into its own source repository, separate from the Explorer API.

It consists of the following components:

• cardano-db library (renamed from cardano-explorer-db)
• cardano-db-sync service (renamed from cardano-explorer-node)
• cardano-db-sync-extended service (a variation of cardano-db-sync used by cardano-graphql)

This release with updated library dependencies follows the release of Cardano Explorer 1.3.0.

Compatible with Cardano node 1.8.0.

Deployed on 23th March 2020.
