Conflux Hydra Network v2.2.4 Upgrade Announcement

This upgrade is mainly to solve the problems below:

RPC Changes

  • Implement trace_epoch in the core space RPC endpoint to return traces of two spaces in an epoch.
  • Update the Log data format returned by cfx filter RPCs.


  • Add keep_snapshot_before_stable_checkpoint to decide whether to keep the snapshot before the era checkpoint. Setting it to false would reduce the disk space usage (it’s still default to true for further testing).


  • Avoid having multiple broadcast tasks for the same peer.

I am a node operator/miner, what do I need to do?

If you have a running node, you need to

  • Suspend the running operation of the node
  • Replace the executable file named “conflux” in the run directory of the original node program with the Conflux executable file of the Conflux v2.2.4 node program.
  • Restart the operation of the node

If you start a new node, you can download the latest version of Conflux v2.2.4 and run it.

What will happen if I do not upgrade the nodes or refuse to upgrade?

This upgrade aims to improve node stability, it’ll be fine if you do not upgrade.
