BTC MicroStrategy Chairman Michael Siler strengthens his opposition to Bitcoin Improvement Proposal 110
MicroStrategy Chairman Michael Siler has stepped up his opposition to Bitcoin Improvement Proposal 110 (BIP 110), arguing that this temporary soft fork could weaken Bitcoin's neutral fundamentals.
Summary
Thaler said that BIP110 restricts transactions through new consensus layer protocol rules, which may endanger Bitcoin's neutrality.
BIP 110 will temporarily restrict data-intensive transactions, but will not affect output created before activation at all.
Miner support remains close to zero, while Siler and Adam Buck warn that controversial rules could lead to a split in Bitcoin.
Thaler: Consensus changes should not determine transaction legitimacy
In an article titled "110 reasons why BIP110 is a bad idea," Thaler said networks should not use consensus changes to determine which valid transactions are entitled to block space. Thaler pointed out in the article that Bitcoin cannot reliably determine the purpose for which transaction data exists. He concluded: "Bitcoin does not need a pure guardian, it needs a neutral guardian."
Thaler challenges consensus limits on transactional data
BIP110, officially known as "Reducing Data Temporary Soft Forks," will implement consensus rules in about a year. The proposal's official specifications will limit large data fields, limit OP_RETURN output to 83 bytes, and set a data payload cap to 256 bytes. Output created before activation is not affected.
Proponents believe that the proposal will reduce arbitrary data storage and reduce the burden on node operators. Thaler acknowledged that certain inscriptions, tokens and documents may have value and may be associated with malicious activity. But he questioned whether those concerns were enough to justify modifying the Bitcoin consensus rules to prevent the current transaction structure accepted by the network.
Neutrality becomes the core of the BIP110 debate
Thaler's argument focuses on the difference between transaction intention and transaction structure. He said the agreement could not know whether the data represented images, certificates, certification records, contracts or other future uses. In his view, miners, node operators and fee markets should deal with controversial activities rather than impose new basic-level restrictions.
This position is consistent with previous conflicts surrounding the proposal. Siler and Blockstream co-founder Adam Barker have opposed BIP 110 and warned that enforcing controversial rules without widespread support could pose the risk of bifurcation. Siler has previously called the proposal's consensus precedent "extremely dangerous."
Miner support remains a key test for BIP110
BIP110 adopts a modified activation process and requires support from 1109 (or 55%) of the 2016 mined blocks. According to a report on July 12, miners 'signal rates are still close to zero, well below the threshold needed to lock in the proposed rules.
Bitcoin developer Luke Dashgill continues to support the proposal. As the debate over ordinals, runes and other data-intensive uses heats up, Dashgill reportedly rejected calls to withdraw BIP 110. Proponents believe that such activities increase storage requirements and divert Bitcoin from its original purpose as a point-to-point currency.
Siler calls for slow change in Bitcoin's fundamentals
Siler's latest comments are in line with his broader view that Bitcoin should change cautiously. He once argued that the value of the network comes from predictable rules rather than frequent functional updates. Criticizing BIP 110, he pointed out that policy tools, pruning, fee pricing and secondary development provide alternatives to managing resource use without changing consensus.
The controversy also tests how Bitcoin can reach consensus when developers, miners, node operators and users disagree. According to reports, Thaler described Bitcoin as a network with balanced capital, node activity and computing power. As BIP 110 nears its activation window, he has placed neutrality at the heart of the debate.
