Bitcoin Ordinals advocate launches DOG Mode to challenge relay limits

DOG Mode increases the maximum individual transaction size to 3.9 million weight units, a tenfold jump from the 400,000-unit limit enforced by Bitcoin Core. The client also lowers the dust threshold to a single satoshi. Because the software operates entirely within existing consensus rules, it does not require a network fork; instead, it relies on individual node operators choosing to relay non-standard transactions that other clients might ignore.

This launch intensifies the ongoing dispute over block space usage by protocols like Ordinals and Runes. Leonidas argues that current relay policies impose arbitrary restrictions on valid, fee-paying transactions, favoring a market-driven approach where users compete for space based on transaction fees. This stance stands in direct opposition to BIP 110, a proposal championed by developer Luke Dashjr that seeks to implement temporary consensus-level restrictions on data-heavy transactions. While BIP 110 proponents cite rising storage costs as a primary concern, critics fear the move sets a dangerous precedent for censorship. The ultimate impact of DOG Mode rests on adoption; its success depends on whether miners and node operators decide that current software policies have become unnecessarily restrictive.
