Bitcoin Ordinals advocate Leonidas has unveiled Bitcoin DOG Mode, a proposed open-source Bitcoin client designed to bypass transaction relay restrictions enforced by Bitcoin Core and Bitcoin Knots. Announced on July 17, 2026, the initiative modifies relay policies without altering Bitcoin’s consensus rules or requiring a hard fork, directly benefiting users of Ordinals and Runes protocols.
The proposed client would increase the maximum standard transaction size from 400,000 weight units to 3.9 million weight units, enabling transactions that fill nearly an entire block without private miner arrangements. It also lowers the default dust limit from 294–546 satoshis to just 1 satoshi, eliminating the need for output padding and unlocking an estimated $25 million worth of satoshis currently tied to relay requirements.
Leonidas argued that many valid transactions are blocked as “non‑standard” under current relay policies, forcing users to send large transactions directly to miners. He noted that the $DOG community previously executed the largest Bitcoin transaction and airdrop by bypassing Core’s relay limits. The announcement comes amid ongoing debates over non‑financial data on Bitcoin, with recent Core updates like v30 relaxing some policies, while proposals like BIP‑110 seek to restrict such data through consensus changes. Bitcoin DOG Mode instead focuses solely on relay policy, remaining fully compatible with existing consensus and inviting developer contributions and miner support.
