A new Bitcoin client called DOG Mode, created by developer Leonidas, proposes to relax default relay policies for Ordinals and Runes transactions without altering Bitcoin’s consensus rules. The change could affect how transactions are propagated across the network and reignite discussions about Bitcoin’s governance.

The proposal emerges amid a broader debate over Bitcoin’s protocol rules. BIP‑110, a previous proposal, sought to tighten network rules to limit data‑heavy transactions, drawing criticism that it amounted to censorship. DOG Mode takes the opposite approach, arguing that block space should remain neutral and that any transaction paying the prevailing fee is equally valid.

DOG Mode does not require a protocol upgrade; instead it modifies the default settings in Bitcoin Core and other node software that determine which transactions are relayed to peers before miners select them for inclusion in blocks. If many nodes adopt different policy configurations, the network’s mempool could become more fragmented, leading to divergent fee estimates and potentially slower confirmation for some transactions. The fragmentation already exists to a limited extent, but broader acceptance of non‑standard transactions could increase its impact. The proposal also aims to lower the reliance on specialized relay services and direct links to mining pools, potentially reducing the influence of institutional transaction brokers.

Adoption of DOG Mode is not yet clear, and it remains unclear whether the approach will gain traction beyond the Ordinals community. The situation underscores the ongoing uncertainty surrounding Bitcoin’s governance structure.
