BIP-110 supporters see Bitcoin as a public utility whose scarce block space should be reserved primarily for monetary settlement. Registrations and other data-intensive applications represent the consumption of a limited resource that should be protected for financial transactions, even if doing so requires introducing new consensus rules.
DOG mode starts from the opposite premise.
Leonidas argued that Bitcoin should remain a neutral market for the block space, where any valid transaction is equally legitimate as long as the sender pays the prevailing fee. From that perspective, there is no objective distinction between a bitcoin payment and an Ordinal inscription.
Rather than seeking permission through a protocol upgrade, the intention of DOG mode is to remove political restrictions that its supporters claim Bitcoin itself never required.
The proposal also raises a more subtle question about Bitcoin’s infrastructure.
If enough nodes start running different policy software, the network’s mempool (the collection of uncommitted transactions waiting to be mined) could become increasingly fragmented. The consensus would remain intact, but different parts of the network could broadcast different transactions, which would affect fee estimation and how quickly some transactions reach miners.
That fragmentation already exists to some extent, but DOG mode could widen those differences by encouraging broader acceptance of transactions that many default nodes currently refuse to broadcast.
