Conflux v2.0.3-testnet Testnet Upgrade Announcement

This upgrade is mainly to solve the problems below:

Incompatible RPC Changes

  • cfx_getLogs and eth_getLogs will no longer support the parameters limit and offset. They are not efficient and can be replaced by setting the block/epoch range instead.
  • cfx_clientVersion will have include more information like web3_clientVersion in eSpace.
  • fromEpoch will default to “latest_state” in cfx_getLogs.
  • fromBlock will default to “latest” in eth_getLogs.


Storage Improvements

  • Avoid re-executing blocks if possible. This will accelerate the recovery process and reduce the disk usage if the node is restarted fast.

Configuration Improvements

  • eSpace will be enabled for dev mode with a default configuration.
  • Enable persit_tx_index for Archive nodes automatically.

Bug Fixes

  • Fix a possible panic caused by inaccurate local timestamps.

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 v2.0.3-testnet node program.
  • Restart the operation of the node
    If you start a new node, you can download the latest version of v2.0.3-testnet and run it.

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

It is strongly recommended to upgrade your node, this upgrade aims to improve node stability.
