The Bitcoin network needs a “conservative” Bitcoin client node software implementation to preserve its monetary properties and strengthen network decentralization, according to Jimmy Song, co-founder of ProductionReady, a non-profit organization that funds open source Bitcoin node software development and education.
Song said ProductionReady has a “bias” against significant code changes unless there is “overwhelming” community support. “The general principle is: if you're not sure a change makes the money better, don't make it,” he told Cointelegraph.
ProductionReady expects to restore the 83-byte OP_Return data limit for arbitrary, non-monetary information in Bitcoin transactions, Song said. He added that limiting arbitrary data helps keep node storage costs down, which he described as essential for network decentralization.
Song argued that keeping the cost of running a node low enough for ordinary users supports a more decentralized and resilient network. He said that when storage and bandwidth requirements grow, fewer people verify for themselves and the network centralizes “by default.”
Song said maximizing the number of nodes and making them accessible to average users hardens the Bitcoin network and reduces the chances of cheating through false transactions or collusion by a small number of actors to centralize the network.
Bitcoin Core remains the software of choice for node runners, with 77.8% of the network running some version of the Core software and 21.8% running Bitcoin Knots, according to Coin Dance.
Coin Dance data also shows there are 4,746 Bitcoin Knots nodes, representing over 21.7% of nodes on the network.
Only about 1% of the network was running the Knots software in 2024 before the decision to remove the OP_Return function was announced.
