Live trackers monitor BIP-110 as block 961,632 nears

Mandatory miner signaling for BIP-110 begins at block 961,632. At the time of reporting miner signaling in the current difficulty period measured about 2.6%. Observers are using real-time dashboards to monitor whether nodes enforcing BIP-110 will remain on the same chain as nodes running existing software when the window becomes mandatory.

BIP-110 is a proposed soft fork that would limit how much non-financial data, such as images or arbitrary files, users can embed in transactions. Backers say the rule would reduce what they call block spam and preserve space for payments. Most miners have not shown widespread support for the change. The mandatory signaling window opens when block 961,632 is mined, marking the transition from optional to required miner signaling for the proposal.

A chain split could occur if miners keep producing blocks that nodes enforcing BIP-110 refuse to accept after signaling becomes mandatory. One direct way to observe the test is to run a standard Bitcoin Core client alongside a build that enforces BIP-110 and watch whether their chain tips diverge at block 961,632. Because most users do not run full nodes or those specific builds, several public monitoring tools provide live views of miner signaling and chain state.

One monitoring portal connects to more than 50 nodes running different implementations and plots the main chain alongside any side branches, indicating which mining pools are mining on each chain. The official BIP-110 monitor shows version-bit signaling in real time, the current difficulty period, the signaling percentage and how many blocks remain before signaling becomes mandatory. Other dashboards highlight blocks and branches that would be rejected under BIP-110, display a countdown to the mandatory window and show the current signaling percentage.

A tailored mempool interface flags transactions or blocks that would violate the proposal’s data limits by identifying oversized outputs and large data pushes. A network monitor reports chain tips and sync status across many nodes, including builds that enforce BIP-110. A mining-pool comparison tool shows high-fee block templates created by a reference node alongside the actual blocks miners produce, revealing which transactions pools include or omit. A signaling dashboard tracks percentage changes across each 2,016-block difficulty period, lists miner signaling by pool and offers a side-by-side “Legacy vs BIP-110” chain comparison.

If a split develops, these tools will show when and where miners and nodes diverge and which blocks are accepted or rejected by different clients. Nodes enforcing BIP-110 could follow a shorter chain or stall until they resynchronize with the larger network if miners continue producing blocks those nodes reject. If miners do not include the prohibited data or if signaling and block production align, the network will continue on a single chain.

Michael Saylor, founder of Strategy, wrote: “With only 2.6% miner signaling, BIP-110 has failed to earn broad miner support. At block 961,632, its nodes will reject non-signaling blocks. BIP-110 will then stall or fork into irrelevance while Bitcoin continues normally. Bitcoin is working as designed.”
