Conflux Hydra Network v2.3.1 Upgrade Announcement

This upgrade is mainly to solve the problems below:

Performance Improvements

  • Extract the MPT database from the key-value database for snapshot storage. It avoids the MPT database copies in most cases. This change will reduce the disk space usage and improve the storage performance.

RPC Improvements

  • Return storagePointProp in cfx_getParamsFromVote.

Bug Fixes

  • Fix wrong gas estimation in RPCs after CIP-107.
  • Fix a race condition in light node connections that may stop the node from syncing.
  • Update the default parameters for SingleMpt storage to provide enough cache entries for execution.

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 v2.3.1 node program.
  • Restart the operation of the node

If you start a new node, you can download the latest version of Conflux v2.3.1 and run it.

What will happen if I do not upgrade the nodes?

We strongly suggest you upgrade to the latest version, otherwise, the transaction packaging process might be affected.
