f2pool Founder Chun: Bitcoin Core v31.0.0 Upgraded on Ubuntu Node
Chun, the founder of mining pool f2pool, stated on social media that Bitcoin Core v31.0.0 has been officially running on the Ubuntu 26.04 LTS system. This means that one of the leading Bitcoin mining participants has begun deploying the latest core client in a production environment. According to the official release from Bitcoin Core, this version is the latest major release, featuring underlying performance optimizations, memory management adjustments, and updates to transaction pool logic to enhance full node synchronization and transaction processing efficiency.
The Bitcoin Core development team previously announced that versions 28.x and earlier have entered a "lifecycle termination" state and will no longer receive security updates. The new version increases the default database cache limit and updates the GUI framework and compilation toolchain to accommodate higher performance and updated system environments.

Chun's demonstration of running Bitcoin Core v31.0.0 on the latest Ubuntu LTS essentially sends a signal to miners and node operators: leading power and infrastructure operators are quickly following up on the new version, which will accelerate the overall network's version migration pace. For the Bitcoin network, who upgrades first and who upgrades later is not just a matter of "software updates"; it directly impacts transaction relaying, block propagation, and potential consensus parameter adjustments in the network layer structure.
From a technical structure perspective, the updates in v31 regarding memory and Mempool logic improve how nodes manage unconfirmed transactions, allowing for more accurate assessment of transaction priority and fee signals under high load conditions, which is particularly critical for mining pools: more efficient transaction selection can increase fee income per block and reduce the risk of nodes stalling or running out of memory during peak times. When large mining pools upgrade first, it effectively pushes the new "transaction packaging rules" economically across the network.
On a deeper level, each major version iteration of Bitcoin Core represents a compromise between "decentralized consensus + highly centralized development": a few core developers and reviewers decide the code path, while thousands of distributed nodes and miners express their opinions through whether or not to upgrade, effectively "voting with their feet." When leading mining pools like f2pool publicly demonstrate their upgrade actions, they are essentially helping the new version achieve a form of "social signal endorsement," increasing the expected benefits for other node operators to upgrade, thereby promoting synchronized progress in the network's technical stack.
