RSK Fingerroot 5.2.0 is Here

Published on: 5 September, 2023

We are excited to unveil the latest version of the RSKj Fingerroot client, now available in the RSKj GitHub repository. This update establishes RocksDB as the default storage library, delivering relevant performance enhancements for database operations.

Although this upgrade is not mandatory, we always recommend that users upgrade their nodes to the latest version available.

What changes are included in RSK Fingerroot 5.2.0?

A non-comprehensive list of changes included in this version is:

  • Make `RocksDb` the default database library in #2063.
  • Change default `networkCidr` config value in #2070.

You can find a complete list of the changes introduced in the corresponding GitHub milestone.

It’s important to emphasize that nodes currently utilizing LevelDB will remain unaffected by this update. To switch to RocksDB as the default database, users must take the following steps: delete their existing database files and restart the node to perform a complete blockchain synchronization.

How do I upgrade to version 5.2.0?

There are no special considerations for upgrading to this version. Users need to download and update their RSKj node; no other task is required.

RSKj Fingerroot 5.2.0’s sha256 sum is 70ae5209720ad6477c1c32d8a8d94e29ebb0db25d57e9903546519d614eddf9f rskj-core-5.2.0-FINGERROOT-all.jar. See the reproducible builds guide for further details.
