Bitcoin reached block height 961,632 late on Saturday, triggering the mandatory signaling period for the highly controversial BIP-110 soft fork. As reported in detail by CoinDesk, the upgrade aims to temporarily restrict the embedding of non‑financial data on the blockchain, but it entered this phase with miner support rarely topping 2.5% – far short of the 55% acceptance threshold required under normal miner‑activated soft fork rules.
What BIP-110 Proposes and Why It’s Divisive
BIP-110 is designed to limit what its proponents call “spam” – arbitrary data attachments that can bloat the UTXO set. Critics, including Strategy chairman Michael Saylor and Blockstream CEO Adam Back, argue the proposal goes against Bitcoin’s permissionless nature and could fracture the network. The debate echoes earlier struggles over block size and fungibility, and as Bitcoin Sizing Backtest: How You Hold BTC Matters as Much as How Much illustrates, even protocol-level changes can have outsized impacts on long‑term holder strategies.
UASF Dynamics and What Comes Next
With miner signaling effectively dead on arrival, BIP-110’s backers are framing it as a user‑activated soft fork (UASF). That would require node operators to enforce the new rules, rejecting blocks from miners that do not comply. The last high‑profile UASF attempt, SegWit, succeeded after a prolonged standoff, but the current environment is different – a recent Another Bitcoin Infra Exploit Hits BTCPay Server, Draining Merchant Lightning Nodes incident has left the community cautious about non‑consensus changes.
Observers warn that a UASF push could lead to a chain split, putting novice users at risk. The core developer community remains largely opposed, and as Bitcoin Holders Risk Losing Real BTC if They Sell Coins from BIP-110 Fork, Developer Warns notes, selling coins from a minority fork could result in loss of the real Bitcoin. For now, the signaling period will run for several weeks, but without a dramatic shift in miner sentiment, BIP-110 appears headed for the same fate as many contentious proposals before it.
