Leonidas, co-founder of the Runestone project, announced the launch of the DOG Mode client for the first cryptocurrency network. Unlike BIP-110, this solution only requires one miner—no majority vote is needed.

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 proposed client modifies two parameters:

  • maximum transaction weight (WU): increased from 400,000 to 3.9 million. For comparison, a full Bitcoin block can hold 4 million WU. This new rule covers almost the entire capacity;
  • the "dust limit," or minimum output size: reduced from 294-546 satoshis to just 1 satoshi.

This will simplify the sending of Ordinals inscriptions and Runes—Bitcoin's equivalents of NFTs and fungible tokens. Both technologies remain contentious within the community, with critics labeling them as "spam."

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

A higher transaction ceiling will allow the transfer of files and entire collections nearly the size of a full block. Currently, Core rejects such transfers as "non-standard," even though they are technically valid. As a result, these transactions are routed through direct channels with miners, such as the Slipstream service from MARA.

The second change—the "dust limit"—will free Ordinals and Runes from excess satoshis in each output. According to the developer, this will release around $25 million in "excess" satoshis.

Leonidas's proposal does not concern network consensus but rather the relay policy—the rules by which a node decides whether to forward a transaction. DOG Mode will eliminate these rules at the level of individual nodes, meaning no threshold of miner support is needed for activation.

Implementing the controversial BIP-110 requires 55% of the network's hash rate. On July 13, support was estimated at around 1%, but by the time of writing, it had dropped below that mark.

As a reminder, in February, Blockstream CEO Adam Back called the update an attack on Bitcoin's reputation and a "Lynch trial."
