In a significant move for the Bitcoin community, Leonidas, a proponent of Bitcoin Ordinals, unveiled his proposal for a new open-source Bitcoin client named Bitcoin $DOG Mode. This initiative aims to raise transaction size limits and lower the dust limit, effectively removing certain policy restrictions imposed by established clients like Bitcoin Core and Bitcoin Knots.
On July 17, 2026, Leonidas shared his vision on X, criticizing existing clients for enforcing rules that he claims are not aligned with the true nature of Bitcoin’s consensus. The proposed Bitcoin $DOG Mode is designed to liberate users from these limitations, providing them with more flexibility in how they conduct transactions.
The new client proposes increasing the maximum individual transaction size to 3.9 million weight units (WU), a significant jump from the 400,000 WU currently permitted by Bitcoin Core. Additionally, the dust limit would be reduced to just 1 satoshi, compared to the existing threshold of 294 to 546 satoshis. This change would facilitate the creation of smaller transaction outputs, allowing users to send minuscule amounts without the need to raise their output values.
If implemented, the Bitcoin $DOG Mode would enable Ordinals users to perform much larger transactions, potentially including extensive collections in a single Bitcoin transaction. This capability could make a marked difference in how digital assets are utilized on the network, especially as Bitcoin-native versions of non-fungible and fungible tokens continue to gain traction.
Leonidas emphasized the long-term objective of his proposal: to amass enough support to compel Bitcoin Core to reconsider its restrictive policies. Supporters of the Ordinals and Runes see them as vital innovations in the Bitcoin ecosystem, while critics argue they occupy precious block space.
The launch of Bitcoin $DOG Mode follows the closure of Ord.io, further underscoring Leonidas's commitment to advocating for broader acceptance of Bitcoin's native digital assets.
