Conflux (CFX) Network rolls out v3.0.2 node upgrade fixing critical RPC bugs and adding new developer endpoints. Optional upgrade improves stability.
Conflux (CFX) Network has released version 3.0.2 of its Coral node software, addressing several RPC bugs and introducing performance optimizations for node operators. The upgrade, announced January 12, is optional but recommended for improved stability.
CFX trades at $0.077 with a market cap of $398 million, essentially flat over the past 24 hours as the technical update drew little immediate price reaction.
What’s Actually Fixed
The most notable bug fix addresses the eth_call coinbase opcode, which was incorrectly returning a random address instead of the proper one. For developers building on Conflux’s Ethereum-compatible eSpace, this was causing headaches with transaction verification.
A second fix targets PoS reward reexecution, resolving an issue where proof-of-stake rewards in the database weren’t properly checked against the pivot chain. Both fixes affect node reliability rather than user-facing features.
New Tools for Developers
The release adds debug_blockProperties, a custom eSpace RPC endpoint that returns extra block property information for all transactions within a block. Why does this matter? Transactions in a single Conflux eSpace block can have different execution contexts—different coinbase addresses, timestamps, and difficulty values. Services needing to verify transaction execution now have a proper tool for the job.
Other RPC improvements include a new blockTimestamp field in log objects and better error handling for block retrieval methods.
Under the Hood
Performance tweaks focus on storage reads and fee history calculations. The node now only reads from storage when entries aren’t already occupied, and eth_feeHistory pulls just block headers instead of full blocks when calculating base prices. Small optimizations, but they add up for high-traffic nodes.
Memory management gets an upgrade too, with a switch to tikv-jemallocator and new profiling support for memory and CPU analysis.
Should Node Operators Upgrade?
Conflux explicitly states this upgrade is optional. Existing nodes will continue functioning without it. That said, anyone running infrastructure that relies on accurate eth_call responses or PoS reward tracking should prioritize the update.
The upgrade process is straightforward: stop the node, replace the conflux executable with the v3.0.2 version, restart. New node operators can simply download the latest release from GitHub.
This maintenance release comes as Conflux prepares for its more substantial 3.1 protocol upgrade, reportedly focused on enhanced scalability and AI-agent interoperability. The network continues positioning itself as a bridge between Eastern and Western crypto markets, leveraging its unique regulatory standing in China.
