Another technological showdown is brewing in the world of bitcoin. The co-founder of the Runestone project, known under the pseudonym Leonidas, has announced the launch of an alternative client for the first cryptocurrency — Bitcoin DOG Mode. This is a direct counter to the controversial BIP-110 proposal, and most importantly, it does not require consensus from the majority of miners to operate.
Two key changes that change everything
DOG Mode adjusts only two parameters, but their effect is colossal. First, the maximum transaction size in weight units (WU) increases from 400,000 to 3.9 million. To put this in perspective: an entire bitcoin block holds 4 million WU. In effect, the new rule allows transactions that take up almost an entire block. Second, the "dust limit" — the minimum output size — is reduced from 294–546 satoshis to 1 satoshi.
These changes directly simplify the sending of Ordinals inscriptions and Runes tokens — bitcoin analogs of NFTs and fungible assets. Critics have long called these technologies "spam," but Leonidas thinks otherwise: "Bitcoin Core and Bitcoin Knots have imposed rules for years that the consensus itself does not require. The DOG army is no longer waiting for permission — it's time to remove excessive restrictions."
Technical background: relay policy vs. consensus
The key point is that DOG Mode does not affect network consensus. It changes relay policy, i.e., the rules by which a node decides whether to forward a transaction further or not. Today, Core rejects "non-standard" transactions, even though they are technically completely valid. This is why large transfers, such as files or entire collections, must be conducted through direct channels with miners — such as MARA's Slipstream service.
The second change — reducing the "dust limit" — solves the problem of excess satoshis in each output of Ordinals and Runes. According to the developer's estimate, this will free up about $25 million in "extra" satoshis that are currently locked in transactions due to outdated restrictions.
Why this matters right now
Activating BIP-110 requires support from 55% of the network's hashrate. On July 13, this figure was estimated at around 1%, and by the time of writing, it had dropped even lower. DOG Mode, on the other hand, does not require a support threshold — any node operator can launch it. This makes it a much more flexible and faster solution for those tired of waiting for consensus.
Recall that in February, Blockstream CEO Adam Back called BIP-110 an "attack on bitcoin's reputation" and a "lynch mob." Now the community has an alternative that bypasses these disputes without violating the network's basic principles.
My analysis: DOG Mode is not a hard fork or an attempt to change bitcoin. It is a tool for those who want to use the network to its fullest without waiting for the conservative majority of miners to change their minds. Given that the volume of transactions with Ordinals and Runes continues to grow, and BIP-110 is losing support, it is precisely such "grassroots" solutions that could become the driver of the next wave of bitcoin scaling.
