An Ordinals developer has unveiled a Bitcoin client as a counter to BIP-110 — ForkLog

# Ordinals developer presents a Bitcoin client in opposition to BIP-110

Co-founder of the Runestone project, under the pseudonym Leonidas, announced the launch of a DOG Mode client for the network of the first cryptocurrency. Unlike BIP-110, the solution needs only one miner—no majority vote is required.

I am very excited to announce the launch of a new open source Bitcoin client called Bitcoin $DOG Mode.

Bitcoin Core and Bitcoin Knots have spent years enforcing rules that Bitcoin itself does not have.

The client proposed by the specialist changes two parameters:

• the maximum transaction size in weight units (WU): from 400,000 to 3.9 million. For comparison, the entire Bitcoin block fits 4 million WU. The new rule covers almost all of that volume;
• the “dust limit,” the minimum output size: from 294-546 satoshis to 1 satoshi.

This will make it easier to send Ordinals inscriptions and Runes—Bitcoin equivalents of NFTs and interchangeable tokens. Both technologies remain a contentious topic in the community: critics call them “spam.”

“Bitcoin Core and Bitcoin Knots have spent years imposing rules that consensus itself does not provide for. The DOG army no longer waits for permission—it's time to remove excessive restrictions,” Leonidas wrote.

A higher ceiling for operations will make it possible to send files and entire collections that are nearly the size of a full block. Today, Core rejects such transfers as “non-standard,” even though they are technically valid. That’s why they are carried out through direct channels with miners—for example, the Slipstream service from MARA.

The second change—the “dust limit”—will do away with unnecessary satoshis for Ordinals and Runes in every output. According to the developer’s estimate, this will free up about $25 million in “excess” satoshis.

Leonidas’s proposal concerns not network consensus, but relay policy—the rules by which a node decides whether to forward a transaction further or not. DOG Mode will override them at the level of individual nodes, so no miner-support threshold is needed to activate it.

Implementing the controversial BIP-110 requires 55% of the network’s hashrate. On July 13, support was estimated at about 1%, but by the time of writing it has fallen below that mark.

Recall that in February, Blockstream CEO Adam Back called the upgrade an attack on Bitcoin’s reputation and a “Lynch court.”
