Bitcoin's DOG Mode client sidesteps BIP 110 without miner consensus
In brief
- DOG Mode raises Bitcoin's max standard transaction from 400k to 3.9M weight units and cuts dust limit to 1 satoshi.
- The client modifies relay policy at individual nodes, bypassing miner approval and consensus requirements.
- BIP 110, the competing anti-spam proposal, has zero miner support and never exceeded 1% signaling.
The relay-policy workaround
Bitcoin Core sets a limit on the largest transaction a node will pass along to its peers and sets the smallest amount of bitcoin an output can hold. Relay policy is separate and softer—it governs what an individual node chooses to forward to its neighbours, distinct from the consensus rules that validate blocks themselves.
DOG Mode changes what one node forwards and does not require network permission or a signaling threshold. If enough nodes run it and any miner takes the fees, transactions confirm. No deadline. No vote. DOG Mode does not have code as of Friday; Leonidas announced an initiative and asked developers to contribute to an initial release.
BIP 110's stalled consensus bid
The contrast with BIP 110 is sharp. BIP 110 is a user-activated soft fork needing 55% of miners to signal support. It's designed to cap arbitrary data on-chain and has drawn virtually no backing. BIP 110 has drawn zero miner support in the current period and has never cleared roughly 1% in any period.
Why the dust limit matters
Ordinals embed images and text directly into transactions, and Runes issue tradeable tokens on Bitcoin. Both have drawn criticism for bloating the chain. Raising transaction limits and cutting the dust floor would ease constraints on these ecosystems.
Leonidas claims removing the dust limit would release about $25 million in padding back to Ordinals and Runes ecosystems. A Bitcoin block holds four million weight units, so Core currently relays nothing larger than a tenth of a block. DOG Mode would allow transactions up to 97.5% of block capacity on a relay basis.
DOG prices were down 1.2% in the past 24 hours after the Friday announcement.
