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

  • If you upgrade your node before the epoch number reaches 229140000 (estimated on Aug 18), you need to replace conflux.exe with the new one in Conflux v3.0.1-testnet-fix under the run directory, then restart the node. You are advised to upgrade a running node within 2 days.
  • If you upgrade your node after the epoch number reaches 229140000 (estimated on Aug 18), you need to delete all data and restart the node.
  • If you start a new node, you can download the latest version of Conflux v3.0.1-testnet-fix and run it.

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

If the Conflux node is not upgraded to the latest version, the node will be incompatible with the upgraded Conflux protocol and cannot interact with the latest Conflux Testnet as expected (functions like synchronizing blocks, mining, etc might be disabled).
