- BIP-110 has failed to gain significant support from miners and the broader Bitcoin community.
A Bitcoin Improvement Proposal, BIP-110, designed to temporarily restrict non-financial data on the blockchain, has ignited a contentious governance debate within the cryptocurrency community. The proposal aimed to make transactions involving images, text, and other data, which have become more prevalent following the Taproot upgrade and the rise of Ordinals and Runes, more difficult.
Supporters of BIP-110 argued it was an effort to restore Bitcoin's original function as peer-to-peer digital cash and to prevent the blockchain from becoming unnecessarily bloated by non-financial data, which could hinder decentralization by favoring large mining operations. The proposal intended a temporary tightening of consensus rules, lasting about a year, to allow for the development of long-term solutions.
However, the proposal faced significant opposition. Critics contended that it represented an attempt to censor specific uses of Bitcoin and that Bitcoin's consensus rules should treat all valid transactions equally, regardless of their purpose. Concerns were raised that creating rules to discourage one type of transaction could set a dangerous precedent for future restrictions on others. The method of approval, which revived discussion around a user-led activation approach rather than broad consensus, also proved contentious, with fears of creating incompatible versions of Bitcoin, similar to the 2017 block-size wars.
Prominent figures like Michael Saylor, founder of MicroStrategy, criticized the proposal, stating it turned a "spam dispute into a consensus change" and warned against setting such a precedent. Veteran developer Adam Back also voiced opposition. Ultimately, BIP-110 failed to garner substantial support from mining pools and the broader Bitcoin community, with minimal miner backing. This outcome highlights the complexities of Bitcoin governance, where lasting changes require alignment across developers, miners, businesses, and users.
