Deep Dive
1. v3.1.0 Hardfork (25 August 2026)
Overview: This is a mandatory network upgrade that introduces seven Conflux Improvement Proposals (CIPs). It focuses on making Conflux work more smoothly with Ethereum-based tools and fixing existing network issues, requiring all node operators to update their software.
The upgrade enhances Ethereum Virtual Machine (EVM) compatibility through three key CIPs: CIP-166 adds a new counting operation, CIP-167 enables direct support for passkey-based logins (like WebAuthn), and CIP-174 adjusts fees for resource-heavy calculations. Four other CIPs fix flaws: CIP-172 standardizes transaction formats, CIP-173 improves validator dispute resolution, CIP-175 corrects permission errors between Conflux's Core and eSpace, and CIP-176 ensures access lists are fully processed. A private security patch is also included, with details to be released after the fork to prevent exploitation.
What this means: This is bullish for $CFX because it makes the network more secure, reliable, and easier for developers familiar with Ethereum to build on. Users can expect a more stable experience and potentially wider adoption of Conflux-based applications.

2. v3.0.3 Node Upgrade (9 April 2026)
Overview: This was a maintenance release that rolled out critical fixes without requiring a network-wide hardfork. It ensured node stability and added a specific Ethereum-compatible feature.
The update activated the CIP-166 opcode, which helps smart contracts perform certain calculations more efficiently, aligning Conflux with latest Ethereum standards. It also resolved seven bugs that could cause nodes to crash or behave unexpectedly, improving overall network resilience.
What this means: This is neutral to bullish for $CFX as it represents proactive maintenance. It results in a more robust and developer-friendly network, reducing downtime and technical issues for everyone using it.

3. v2.4 Hardfork (August 2024)
Overview: This was a foundational protocol upgrade that introduced incompatible changes, requiring a coordinated network hardfork. It significantly modernized Conflux's core economics and scalability.
Key changes included implementing a new fee model similar to Ethereum's EIP-1559, which introduces a base fee that is partially burned. The block gas limit was doubled from 30 million to 60 million, and the network began supporting newer transaction types (Type-1 and Type-2). Several bug fixes and EVM opcode updates were also part of this major version jump.
What this means: This was fundamentally bullish for $CFX as it laid the groundwork for higher network capacity, more predictable transaction fees, and better long-term economic sustainability.

Conclusion
Conflux's development trajectory shows a clear pattern of major foundational upgrades followed by incremental optimizations and compatibility enhancements, with the upcoming v3.1.0 hardfork representing the next step in refining network security and Ethereum alignment. How will the successful execution of this hardfork influence developer migration and on-chain activity in the coming quarter?
