Conflux (CFX) announces a critical hardfork upgrade for its testnet, urging all node operators to update before August 18, 2025, to ensure compatibility and uninterrupted operations.
Conflux (CFX), a notable player in the blockchain space, has unveiled its latest upgrade, the v3.0.1-testnet-fix, as it prepares for a significant hardfork on its testnet. The upgrade is set to occur before the epoch number reaches 229140000, estimated to be around August 18, 2025. According to the Conflux Forum, all node operators are encouraged to implement this upgrade to maintain network compatibility and functionality.
Key Improvements and Bug Fixes
The v3.0.1-testnet-fix introduces several enhancements, including a detailed version return for the command conflux --version. Among the critical bug fixes are corrections to the CIP145 implementation and the resolution of an issue involving incorrect ws_address usage for opening RPC endpoints. Additionally, it addresses a mismatch error between the definition and access of RPC arguments.
RPC Changes
Among the notable changes, the RPC method eth_getBlockByNumber has been updated to return null if the parameter exceeds the latest block number. This adjustment aims to enhance the reliability of the network interactions.
Node Operator Instructions
Node operators are advised to upgrade their systems before the specified epoch number. For those upgrading after the epoch threshold, a complete data reset is required. New node setups should utilize the latest version of Conflux v3.0.1-testnet-fix for optimal performance. The upgrade involves replacing the existing conflux.exe file within the ‘run’ directory and restarting the node. It is recommended to perform these updates within two days to avoid disruptions.
Consequences of Non-Compliance
Failure to upgrade nodes to the latest version will result in incompatibility with the updated Conflux protocol. This could lead to disabled functionalities such as block synchronization and mining, severely impacting network operations.
Conflux extends gratitude to its community for their ongoing support and contributions towards the ecosystem’s development. The collaboration of developers and community members continues to drive Conflux’s mission forward.
