Conservative Bitcoin Client: Jimmy Song Backs ProductionReady Funding

Jimmy Song argues for a “conservative bitcoin client” focused on protecting Bitcoin’s core monetary properties: fixed supply, anti-censorship, permissionless access, and neutrality. Changes to the protocol should be rejected by default and only accepted with overwhelming support. Song says the proposed client will be built on Bitcoin Core because it has faced the longest and most hostile real-world testing cycle (16 years) without being successfully “broken.” The goal is not to rewrite consensus code, but to diverge on the development process, default node policies, and governance—while keeping the underlying consensus compatible so operators can switch with low risk. A key motivation is the need for a third implementation. With only one dominant client, developers can effectively steer network-wide decisions, creating an implicit “centralization risk.” Song points to adoption dynamics after Bitcoin Core v30 removed a data-size limit for single-transaction OP_RETURN payloads: many nodes moved to Bitcoin Knots, whose adoption reportedly rose from about 2% to 15% in weeks. Long term, Song frames the aim as avoiding undesirable ossification-by-chaos while still proving stability can be achieved through strict standards for necessary changes. The initiative is supported by the independent, transparent nonprofit ProductionReady fund, launched to finance a long-lived client without strings attached. Overall, the article centers on strengthening decentralization at the code level via a conservative bitcoin client and a third implementation path backed by ProductionReady.
