Blockstream's Adam Back Voices Strong Opposition to Failed BIP-110 Bitcoin Fork Proposal

Adam Back's Stance on BIP-110

In a recent post on social media platform X, Adam Back, the CEO of Blockstream, reiterated his stance against Bitcoin Improvement Proposal 110 (BIP-110). He claimed that the proposal to implement significant changes to Bitcoin's network has not gained traction in the marketplace. Back’s comments on November 3 included references to remarks made by Bitcoin advocate Francis Pouliot, who warned against trying to force particular changes through Bitcoin's established consensus processes.

Market Rejection of New Ideas

Back emphasized that attempts to impose new ideas onto Bitcoin often meet with rejection from the market, reflecting past disputes over the cryptocurrency's operational rules. He described Pouliot's insights as a significant lesson in understanding the principles of Bitcoin, particularly the concept of immutability that governs its history and functionality. Back remarked,

"Efforts to impose your views on bitcoin get market rejected."

This statement supports his argument with historical context surrounding disagreements over Bitcoin’s rules.

The Technical Aspects of BIP-110

The ongoing discourse surrounding BIP-110 involves a proposed soft fork, which aims to limit specific forms of non-financial data storage on the Bitcoin network for an experimental duration. However, Back stressed that this conflict transcends mere technicalities related to data payloads, indicating that overriding consensus is likely to encounter resistance from the market, even if backers of such proposals believe they offer improvements.

Back further contended that BIP-110 had significant technical flaws and failed to pass initial assessments, reiterating his concerns about the potential for the proposal to split the Bitcoin community. His earlier warnings about the proposal, reiterated in reports from July, included skepticism from other prominent figures such as Michael Saylor, who also questioned the validity of altering Bitcoin's consensus for transaction restrictions.

Details of the Proposal

The proposal, authored by developer Dathon Ohm and formally titled the Reduced Data Temporary Softfork, aims to impose stricter criteria on the data included in Bitcoin transactions. It suggests limiting standard outputs to 34 bytes, except for OP_RETURN outputs, which could be as large as 83 bytes. Proponents argue that such restrictions would ease the storage burden on Bitcoin nodes and assist in maintaining Bitcoin's efficacy as a payment medium.

Criticism and Current Status

However, critics caution that modifying consensus rules could compromise Bitcoin’s neutrality and integrity. As of now, the status of BIP-110 is listed as Closed. The divided factions escalated the debate after BIP-110 supporters attempted to validate their rules, which necessitated 55% approval from miners. Yet, during the signaling period, only 2.53% of blocks supported the proposal, leading to its rapid decline.

In early August, a faction validating BIP-110 rejected a block that was accepted by the primary Bitcoin network, resulting in the creation of a minority chain that ultimately failed to sustain itself in the competitive mining environment. Suggestions to alter the mining algorithm to BLAKE2b for this minority network were floated, moving away from Bitcoin’s SHA-256 mining method.

Participation and Adoption Rates

Recent statistics show disappointing participation for BIP-110; only about eight nodes out of nearly 19,000 observed nodes currently enforce it, representing a mere 0.04% adoption rate. This is a stark contrast to previous counts where hundreds of nodes were reported as compatible. Bitcoin Core remains the dominant software, comprising around 90% of the observed nodes, while Bitcoin Knots, which might support BIP-110, accounted for roughly 10%.

Conclusion

Back's latest criticism is a continuation of his viewpoint on the difficulties surrounding contentious Bitcoin forks and how they challenge the immutability principle that is fundamental to the Bitcoin network. He concluded with a thought-provoking reflection on time, stating,

"Time is a flat circle."
