The Short Version
BIP-110 is a proposed soft fork of Bitcoin that would limit arbitrary data in transactions —
ostensibly to reduce "spam" and keep the network focused on monetary transfers. If it activates at
block 961,632, nodes running it will reject blocks that don't comply, potentially causing a
chain split: two competing versions of Bitcoin.
What Happens at Block 961,632?
BIP-110 mandates activation via a User-Activated Soft Fork (UASF) at block 961,632. Any block not
signaling bit 4 gets rejected by BIP-110 nodes. If miners don't comply — and currently zero miners
signal support — the network could fracture into two chains. This countdown tracks how close that
moment is.
Why Is It Controversial?
Critics argue BIP-110 restricts legitimate Taproot features, could freeze funds in edge cases, and
introduces subjective censorship into what should be a neutral protocol. The low 55% miner-signaling
threshold is considered reckless — previous contentious forks required near-supermajority miner
support to avoid chaos.
Proponents believe arbitrary data (Ordinals, inscriptions, etc.) is harmful "spam" that burdens node
operators and dilutes Bitcoin's identity as money. They see BIP-110 as a necessary cleanup.
Will It Actually Succeed?
Unlikely in the near term. No mining pools currently signal support, and miners have little incentive
to voluntarily reduce their fee revenue. Without miner buy-in a UASF-only activation risks a messy
split rather than a clean upgrade.
