Conflux v2.2.3-testnet Testnet Upgrade Announcement

This upgrade is mainly to solve the problems below:

Bug Fixes

  • Fix an issue that makes peers disconnected periodically.

RPC Changes

  • Add debug RPCs cfx_getTransactionsByEpoch and cfx_getTransactionsByBlock to get the original transactions in both spaces atomically. This is only available in the local RPC port and phantom transactions will not be returned.

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 v2.2.3-testnet node program.
  • Restart the operation of the node
    If you start a new node, you can download the latest version of Conflux v2.2.3-testnet 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’s recommended to upgrade to this version.
