Discussions surrounding the BIP-110 upgrade proposal are intensifying within the Bitcoin community, drawing sharp criticism from Blockstream CEO Adam Back. The proposal aims to limit the storage of non-financial data, such as images and videos, on the blockchain. However, concerns persist regarding the potential impact of this upgrade on users and the network.
Adam Back highlighted that the BIP-110 proposal only requires 50% miner support for activation. In contrast, Bitcoin's traditional upgrade mechanisms typically require around 95% consensus to avoid network splits. Such a low activation threshold significantly increases the risk of a chain split. If a split occurs, it could result in multiple competing Bitcoin networks, confusing users and severely damaging community trust in the network.
Furthermore, Adam Back mentioned that some proponents of the proposal seem willing to accept "collateral damage" to address the issue of spam. He considers this approach highly dangerous, especially when it affects ordinary users. He further emphasized that spam is currently more of an inconvenience than a direct security threat.
Chain Splits and Concerns Over Fund Accessibility
The controversy around BIP-110 also touches upon technical and reputational risks. Adam Back stressed that a mechanism to freeze certain transaction outputs could effectively prevent users from accessing their funds. This would represent a severe breach of user expectations for the Bitcoin ecosystem.
Currently, BIP-110 has low support. It is estimated that only 2.4% to 4.5% of nodes support the proposal, with the majority running the Bitcoin Knots client. Meanwhile, major mining pools have not shown interest in adopting this upgrade.
Adam Back concluded that under the current circumstances, BIP-110 is unlikely to gain widespread support and, given its limited backing, is effectively unfeasible. However, the debate surrounding BIP-110 itself reveals deeper divisions within the Bitcoin ecosystem.
