Bitcoin Core Developers Spark Debate on Non-Monetary Uses

On June 6, 2025, 31 Bitcoin Core developers released a joint statement outlining their position on the handling of non-monetary uses within the Bitcoin network. The developers emphasized that their role is not to support or block data inscriptions and other non-financial activities, but rather to ensure the network remains resistant to censorship. This stance has sparked intense debate within the community, with discussions revolving around freedom, fees, and the fundamental purpose of Bitcoin.

The Core team clarified that they will not intervene to stop "harmless" data from being added to the blockchain. They highlighted that Bitcoin's strength lies in its resistance to censorship, and thus, any user-driven software choices must be respected. This approach aims to maintain the network's freedom, even if it means accommodating additional data. The developers also stated that it is up to node operators to decide what they accept, further emphasizing the decentralized nature of the network.

Following the statement, reactions from the community were mixed. Samson Mow, CEO of JAN3, criticized the developers' tone as hollow and argued that recent changes have opened the floodgates for spam. He believed that removing technical barriers encourages unwanted data and that the developers' statement was disingenuous. On the other hand, Jameson Lopp of Casa praised the clear explanation of relay rules, noting that a unified voice from developers helps to reduce past confusion over policy.

On May 8, 2025, Core developers removed a long-standing limit on transaction data size, allowing anyone to include larger chunks of information in transactions. Critics expressed concerns that this change could lead to increased blockchain bloat and higher fees. Supporters, however, argued that predicting what miners will include and passing that information along is crucial for the smooth operation of Bitcoin. They claimed that this neutral relay policy benefits both miners and users, despite not being universally accepted.

Looking ahead, some in the community anticipate a new fork that could create a "pure money" chain, blocking data inscriptions. Others envision layer-2 networks or sidechains taking on the burden of art, messaging, and other uses. Regardless of the outcome, most agree that wallets and node software will soon offer options: one for clean, finance-only transactions and another for those who do not mind extra data. This choice will allow users to vote with their settings, rather than relying on developers to make the call.
