Bitcoin Ordinals advocate Leonidas proposes a new open source client to increase transaction size limits and lower dust thresholds
Bitcoin Ordinals advocate Leonidas has proposed a new open source Bitcoin client that will increase transaction size limits and lower dust thresholds, aiming to eliminate policy restrictions that affect Ordinals and Runes transactions.
Summary
Leonidas proposed a new Bitcoin client that aims to increase transaction size limits and lower dust thresholds for Ordinals and Runes. Bitcoin $DOG Mode is designed to remove policy restrictions enforced by Bitcoin Core and Bitcoin Knots rather than imposed by Bitcoin Consensus Rules. The proposal came months after Ord.io closed, and Leonidas continues to push for broader support for Bitcoin's native digital assets.
In a post on Platform X (formerly Twitter) on Friday, Bitcoin Ordinals advocate Leonidas introduced a proposal to replace the Bitcoin client called Bitcoin $DOG Mode. He described it as a piece of software designed to remove restrictions imposed by existing Bitcoin clients that do not come from the Bitcoin protocol itself.
Leonidas said: "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 been enforcing rules that do not exist in Bitcoin itself for years. A deal is fully effective at the consensus level, but may still be prevented from spreading..."
The client in the proposal would increase the maximum single transaction size of 400,000 weight units (WUs) allowed by Bitcoin Core under the default policy to 3.9 million weight units. At the same time, it also lowered the dust threshold to 1 Satoshi, while Bitcoin Core currently requires 294 to 546 Satoshi for standard transactions.
According to Leonidas, Bitcoin Core and Bitcoin Knots have implemented trading strategies that do not fall under the Bitcoin consensus rules for many years. He said the new client is designed to remove restrictions he considers unnecessary, adding that the long-term goal is to attract enough users for Bitcoin Core to eventually rethink these strategies.
Larger transactions and smaller outputs
If the proposal is adopted, higher transaction limits will allow Ordinals users to include larger inscriptions and even entire collections in individual Bitcoin transactions, including those that occupy most of the space in a block. Lower dust thresholds will also make it easier to create extremely small trading outputs. Under the default rules currently used by Bitcoin Core nodes, users typically need to increase the output value above a minimum threshold for transactions to spread across the network. Bitcoin $DOG Mode allows outputs as small as 1 Cong.
Bitcoin $DOG Mode is positioned as an alternative to Bitcoin Core and Bitcoin Knots, the latter two currently most widely used Bitcoin clients.
Ordinals and Runes have been controversial since their launch. Proponents regard them as bitcoin's native non-homogeneous tokens and homogeneous tokens, while critics believe that they occupy valuable block space and are equivalent to online spam.
Proposal follows the closure of Ord.io
The proposal was released just a few months after Leonidas announced the closure of Ord.io, one of the earliest Ordinals browsers. In May this year, he said the project would cease operations after the team ran out of funds and no longer saw a sustainable development path. Ord.io will launch in 2023 and had served more than 1 million users before announcing its offline plan. Its related consumer application Zap also stopped operating because it failed to achieve enough user growth. At the same time, the team said it would keep Ord.io's public data on GitHub and remained open to other teams taking over the project.
Activity related to Bitcoin inscriptions has cooled down after strong demand in 2023 and early 2024. Runes incurred $135 million in fees in the first week after Bitcoin's 2024 halving, but trading activity has declined since then.
