Bitcoin Network Advocates for Conservative Node Software to Enhance Decentralization

The Bitcoin network is urged to adopt a conservative approach to its client node software implementation to maintain its monetary properties and bolster network decentralization. According to Cointelegraph, Jimmy Song, co-founder of ProductionReady, a non-profit organization dedicated to funding open-source Bitcoin node software development and education, emphasizes the importance of cautious code changes. Song notes that the organization is biased against significant code modifications unless there is overwhelming community support. Song articulates a guiding principle: if a change does not clearly improve the monetary aspect of Bitcoin, it should not be implemented. ProductionReady aims to restore the 83-byte OP_Return data limit for non-monetary information in Bitcoin transactions, highlighting the necessity of keeping node storage costs low to ensure decentralization. Song explains that the more self-sovereign Bitcoin users become, the more decentralized and resilient the network is. This requires maintaining low costs for running a node, allowing ordinary individuals to participate. The Bitcoin network's decentralization is strengthened by maximizing nodes and making them accessible to average users, thereby reducing the risk of false transactions or network centralization through collusion. Bitcoin Core remains the preferred software for node operators, with 77.8% of the network running some version of the Core software, while 21.8% run Bitcoin Knots. In 2025, node storage and on-chain spam became contentious issues after Bitcoin Core developers altered the 83-byte data limit in Bitcoin Core version 30, the latest major upgrade to the reference implementation for Bitcoin node software. Despite significant community opposition, the limit was increased to 100,000 bytes. The proposal to change the limit received four times as many downvotes as upvotes on its GitHub pull request page. The release of Bitcoin Core 30 in October 2025 led to a historic surge in the number of Bitcoin nodes running Bitcoin Knots, an alternative node client software. The number of Bitcoin Knots nodes reached record highs, representing over 21.7% of nodes on the network, according to Coin Dance. Prior to the decision to remove the OP_Return function, only about 1% of the network was running the Knots software in 2024.
