Less Than 2 Weeks Left — Bitcoin’s BIP-110 Clock Starts Ticking as Miner Support Creeps Higher Before Showdown

At the clip of penning astatine 8:40 a.m. Eastern clip connected July 27, the concatenation extremity stood astatine artifact 959842. Roughly 1,790 blocks stay earlier artifact 961632, the constituent wherever nodes moving BIP-110 bundle statesman rejecting blocks that bash not awesome mentation spot 4. At Bitcoin’s average ten-minute pace, that tallness should get connected oregon astir Aug. 9, 2026.

BIP-110, formally called the Reduced Data Temporary Softfork, proposes limiting the size of definite information fields utilized successful Bitcoin transactions. The rules chiefly people Ordinals-style inscriptions, oversized OP_RETURN payloads, and akin data-heavy uses portion leaving mean finance-centric bitcoin transfers, key-path Taproot spends, and modular Lightning transmission operations unchanged.

If activated, the restrictions statesman astatine artifact 965664 and expire automatically aft 52,416 blocks, oregon astir 1 year.

Support Is Growing, Just Not Fast Enough

The signaling charts person looked antithetic implicit the past period than they bash astatine archetypal glance.

A fewer weeks ago, BIP-110 signaling hardly registered, hovering beneath 1% during immoderate periods. Since then, enactment has climbed into the 3% range. That’s a meaningful summation successful percent terms, but Bitcoin activations are driven by who is signaling, not simply however galore blocks transportation the bit.

Ocean continues to account for astir of the signaling activity. The remainder of the hashpower is built astir wholly by autarkic miners and smaller operators. The miners presently signaling for BIP-110 see Roughnecks, SoV, BIP110 Generic, Barefoot Mining, 234 Alberta, 888, Peer to Peer Money, Black Jade Advisors, Sazmining, Crestmont Fabrics, Datum Miner, SpammersGFY, Moonwalk, PyBLOCK-Datum, Just For Krypto, and JAMIN.

Meanwhile, Foundry, Antpool, ViaBTC, and F2pool, the 4 pools liable for astir of the network’s hashrate, person shown small movement. Until 1 of those operators changes course, gradual increases from smaller participants are improbable to materially alteration the activation picture.

The bundle ecosystem reflects the aforesaid divide. The lone implementation enforcing the connection is simply a Bitcoin Knots fork. Reachable nodes moving that bundle stand astatine astir 22% today, leaving enforcement concentrated among a comparatively smaller stock of the web compared to Bitcoin Core nodes.

Foundry Holds the Biggest Swing Vote

Among the large mining pools, Foundry has taken an absorbing approach.

Around July 17, 2026, the institution asked customers to ballot connected whether the excavation should statesman signaling for BIP-110. Rather than making the determination internally, Foundry tied the result straight to its clients’ hashrate, according to an email sent to excavation participants.

“The voting model connected Foundry USA Pool™ volition beryllium unfastened done the signaling model adjacent date, up of artifact 961,632,” Foundry USA excavation wrote connected its BIP-110 assets page.

Voting powerfulness is based connected each customer’s mean hashrate. Clients who bash not respond are automatically counted arsenic “No,” and Foundry’s default presumption remains to awesome against the proposal. Only if “Yes” votes transcend 51% of participating weighted hashrate volition the excavation power each of its blocks to signaling support.

That determination matters due to the fact that Foundry represents betwixt astir 23% and 33% of Bitcoin’s planetary hashrate, depending connected the measurement period. If a excavation of that size flipped overnight, the signaling charts would alteration immediately.

As of today, determination has been nary denotation that specified a displacement has occurred.

Foundry has besides avoided endorsing either broadside publicly. Instead, its lawsuit assets leafage links to the BIP specification, the archetypal bitcoin-dev discussion, disapproval from Jameson Lopp, and commentary from Adam Back, Michael Saylor, Luke Dashjr, and others, allowing customers to measure the connection themselves.

What Happens if the Window Opens Without Broad Support?

The mechanics go overmuch much consequential erstwhile artifact 961632 arrives.

If existent signaling levels persist, nodes enforcing BIP-110 volition cull blocks mined by astir of the web due to the fact that they deficiency the required mentation bit. Those nodes volition alternatively travel the comparatively tiny fig of signaling blocks.

Legacy nodes volition behave differently. They volition proceed accepting some signaling and non-signaling blocks portion pursuing the concatenation with the greatest accumulated proof-of-work, arsenic Bitcoin has ever done. Several autarkic observers person built dedicated monitoring sites that way activation parameters, with immoderate adjacent simulating however the process could unfold nether antithetic scenarios.

The monitoring tract BIP110 Situation Monitor besides models a scope of imaginable outcomes during the mandatory signaling window. Its simulation leafage lets users set variables, including the percent of web hashrate expected to enactment BIP-110 successful August. The simulation representation supra is with 25% hashrate dedicated to BIP-110, resulting successful a concatenation split.

That creates the anticipation of 2 competing chains, but not 2 arsenic viable ones. The concatenation recognized by Bitcoin Core and mined by the overwhelming bulk of hashrate would proceed producing blocks astatine its mean pace. A number concatenation consisting lone of signaling miners would beforehand overmuch much dilatory until reaching its adjacent 2,016-block trouble adjustment.

That imaginable result explains wherefore overmuch of the statement has shifted distant from inscriptions and toward the activation process itself.

A Different Activation Strategy

BIP-110 follows a deployment way that differs from Bitcoin’s 2 astir caller large brushed forks.

The connection launched connected Dec. 1, 2025, utilizing a modified BIP-9 process. It required 1,109 of 2,016 blocks, oregon 55%, signaling during a azygous trouble play to fastener successful early. If that threshold was ne'er reached, the connection advances toward a forced lock-in astatine artifact 963,648 earlier activating 1 trouble play aboriginal astatine artifact 965,664.

Between those milestones sits the mandatory signaling window.

From artifact 961,632 done 963,647, nodes enforcing BIP-110 cull each artifact that does not awesome mentation spot 4, careless of however overmuch proof-of-work supports it. That attack differs from some Segwit and Taproot, wherever non-upgraded nodes continued accepting the strongest proof-of-work concatenation passim activation.

The closest humanities examination is the 2017 BIP-148 user-activated brushed fork (UASF), which besides attempted to unit miners done mandatory signaling requirements. That confrontation yet ended without a lasting concatenation divided aft capable hashrate shifted earlier the deadline. BIP-148’s UASF yet served much arsenic leverage than existent activation.

Whether BIP-110 follows the aforesaid way depends mostly connected whether 1 oregon much large pools alteration presumption earlier Aug. 9.

Why Supporters Want the Change

BIP-110 was authored nether the sanction Dathon Ohm. Earlier versions circulated nether the BIP-444 designation earlier being accepted into the BIPs repository.

BIP-110 Supporters reason that inscriptions, BRC-20-style tokens, and progressively ample OP_RETURN payloads rise the outgo of operating a afloat node, distort Bitcoin’s interest market, and displacement web resources distant from Bitcoin’s intended intent arsenic a outgo and colony system.

“Removing rules is simply a hardfork,” BIP-110 protagonist and Bitcoin Knots developer Luke Dashjr explained connected X successful aboriginal July. “That includes scheduled rules similar subsidy halvings, and yes, adjacent BIP110. Rejecting BIP110 is simply a contentious hardfork attempt.”

Dashjr added:

“And dissimilar softforks, hardforks request statement to succeed. There is nary statement connected rejecting BIP110.”

Opponents mostly hold that spam exists but disagree implicit whether BIP-110’s activation mechanics is the due solution. “OP_RETURN blockspace usage hasn’t accrued overmuch since Bitcoin Core v30 was released. Oversized OP_RETURNs whitethorn beryllium up slightly, but inactive they devour little than 0.1% of blockspace,” Alex Thorn, Galaxy Digital’s caput of research, wrote connected X.

Thorn continued:

“BIP-110 is an highly disruptive & unsafe effect fixed the tiny interaction from these prunable [transactions].”

The Final Days Could Still Change Everything

The adjacent 2 weeks volition apt travel down to 3 developments.

The archetypal is whether 1 of the largest mining pools begins signaling support. The 2nd is whether large exchanges publically clarify which concatenation they would admit if competing chains look aft artifact 961,632. The 3rd is what miners really bash erstwhile the mandatory model opens, due to the fact that signaling percentages starring up to the deadline lone archer portion of the story.

The inclination has been moving successful BIP-110’s favor, climbing from beneath 1% to astir 3% arsenic the deadline approaches. Even so, the connection remains acold from demonstrating wide miner backing. Unless 1 of Bitcoin’s largest pools changes people successful the days ahead, the mandatory signaling model appears acceptable to unfastened with enactment inactive concentrated among a comparatively tiny information of the network.
