Bitcoin’s BIP-110 soft fork effort failed to secure the 55% miner signaling required during its deployment window, leaving the proposal without meaningful network support. The push briefly created a minority chain that mined just two blocks before stalling at block height 961,633. The proposal was designed to temporarily restrict several forms of arbitrary data on Bitcoin, but the result highlighted the difficulty of advancing protocol changes without broad miner participation. The article also says the initiative has resurfaced with supporters seeking to replace miners and change PoW (proof-of-work, the system miners use to secure the network).
