It'll only serve as a check on the direction of development if people use it.
So my question is, what exactly will be the product differentiation that will get people to use it?
If the answer is different policy defaults that seems a bit underwhelming since, well, they're defaults and can already be changed...

No offense taken, I think this is exactly right. And both the Iranian and the UAE governments probably know this as well.
To be fair, I have seen some “we’re not fucking leaving” sentiment among expats. But as mentioned daily life is also still pretty normal; I doubt it will persist for very long if things keep getting tougher from here.

It’s a jihadist regime that killed thousands, perhaps tens of thousands, of its own citizens earlier this year.

There is a US airbase in Abu Dhabi, but the UAE government is explicitly not letting the Americans use it to attack Iran. Nevertheless this is the excuse the IRGC is giving: they say they’re “just” attacking US bases and assets. (If true they would appear to have very bad aim.)
It seems more like the Jihadist regime is basically taking the entire region hostage to gain leverage in this war.

So I’ve been living in Dubai since last summer. Not because I like the city — I don't — but because my girlfriend lived there when we met and she wasn't quite ready to leave yet. Admittedly the tax benefit is nice too.
Earlier this week we decided to get out however, at least for a couple of weeks, to see how the situation develops without being in the middle of it. The uncertainty of it all and potential for escalation is just not a comfortable situation to be in.
With that said, daily life in Dubai was in fact quite normal still when we left— just a bit more quiet. The Starbucks is open, the sports bar serves cold Guinness, and Domino’s is delivering to your doorstep.
There were missile alerts on our phones maybe once a day, and we could sometimes hear the sound of an explosion, mostly from interceptions I believe. But other than that, if you wouldn't watch the news, you may not even know something was going on.
I’ve seen reports on reputable international news media suggesting that influencers are required to convey a positive image of Dubai in these times— and are being barred from posting anything negative about what’s going on. I don’t know to what extent that’s true — I wouldn’t put it past the local authorities — but I do know that I am myself not some Dubai propagandist or Emir simp, yet I also got the impression that the UAE government is dealing with the attacks quite well, so far at least.
Also on the topic of influencers, I have seen a good amount of schadenfreude on social media etc. with people mocking the "influencer class" that now finds itself in the middle of rocket fire. I get it and part of me even feels the same way. But you know, most people in Dubai aren't influencers.
In fact, most people in Dubai are actually guest workers from places like South and Southeast Asia that work in the UAE to send money back to their family. And if shit really would hit the fan, guess who'll actually be most likely to get stuck there without an easy way home? Yeah probably not the influencer class.
If things in Dubai do take a turn for the worse from here and we don't return, I won't miss the city personally— but I will feel bad for these millions of people that were just living their lives peacefully until the jihadist regime across the sea decided to drag them into a war none of them had anything to do with, and no one wanted to be part of.

URSF stands for User Rejected Soft Fork.
If miners were to activate BIP110, URSF nodes would reject this so the chain splits between BIP110 nodes that enforce the new soft fork rules and URSF nodes that don't.
It's a way for users and miners to say: we're not going along with your soft fork, and we'll keep using the Bitcoin protocol as it was.

2026-02-27 10:23:11 UTC

For anyone interested, there’s now a Telegram channel to discuss BIP110 URSF specifics: https://t.me/+svDDMRJtO8UzMzNk

Yes I agree with your premise.
I would also encourage the development of a URSF for that reason, if you (or anyone else) don't consider it a waste of your time and effort.

2026-02-17 17:34:42 UTC

- reply

I doubt it would represent a significant loss, and in fact I suspect that adopting BIP110 would harm the value of bitcoin more than losing these people would. But without fork futures markets --which I'm very much in favour of!-- it's anyone's guess unless and until there actually is a split.
(That's another argument for a URSF btw, it would enable a very well defined fork futures market.)

2026-02-17 17:28:22 UTC

- reply

(To be precise I think the 1109th signaling block within a difficulty window should be rejected, as that would bring it over the 55%-threshold, and makes for a relatively clean split between the BIP110 chain and the original chain.)

2026-02-17 17:22:11 UTC

- reply

Last I checked BIP110 will have a mandatory signaling window in August, so if miners don’t signal, BIP110 nodes will in fact fork themselves off the network.
Your scenario could still happen if miners do signal (which non-BIP110 won’t care about one way or the other). That’s why IMO it’s still good to pay attention to signaling, and if there is any it’s probably time to start considering a URSF.
The worst case scenario is if miners don’t signal until very shortly before the mandatory signaling period starts. (Or even when it’s already started.) In that case I suppose the rejectblock command can still offer a solution, but it’d be a bit of a last-minute scramble…

2026-02-17 17:00:26 UTC

- reply

No miners are currently signaling support for BIP110, so investing time and effort in developing a URSF client seems like a waste of time and effort at this time (to me, anyways).
Much easier to just use the rejectblock command post-fork if a BIP110 block that forks the chain is ever mined.

2026-02-17 15:22:21 UTC

Devs can't do that.
They can only release free and open source software that users can then voluntarily decide to run-- or not.

Yes most OG Bitcoiners are against arbitrary data storage on Bitcoin. That’s why we fought to keep blocks small. F(r)ee market economics should do the rest in an open, permissionless and censorship resistant system.

No, they’re mostly newer Bitcoiners— but my experience with them is very reminiscent of what I dealt with when engaging with big blockers back in the day. (The simplistic talking points, the misattribution of authority to Bitcoin Core, the conspiracy-fueled outrage…)

Not unless you mean it in a “voting with your feet” kind of way.
Everyone can just use whatever software they want. Including software that is incompatible with the Bitcoin protocol.

2026-02-13 08:12:01 UTC

I was tagged in an X post by @npub1r8l…x5dk correctly dismantling the false narrative that BIP110 is today largely supported by the small block faction of the block size war era.
There’s been a bunch of stolen valor post-block size wars: maxis that associated themselves with the small block movement, but actually weren’t around at all during the 2015-2017 years, or at least weren’t well-known at the time.
Out of the prominent small blockers of these days, I believe *only* @npub1lh2…a9nk @npub1lh2…a9nk is now in favour of BIP110. Everyone else that I can think of is either against it, or maybe in a few cases still kind of neutral/undecided.

Right, this OP basically confirms my point.

Even in the post itself he leaves himself an explicit out, showing an obvious lack of conviction.

I received a few requests to write an article or record a podcast on BIP110, but frankly I don’t see the point right now.
Until someone is willing to put their money (no one has taken on @npub1emd…c9aw’s fork futures offer) or hash power (not even Ocean is signaling support) where their mouth is, it’s little more than a DOS-attack on our attention and time.

The same is true for BIP110 so by your own logic that would be a hard fork too.

It's not essentially a hard fork-- it's a soft fork. And it doesn't necessarily have to be done by Core. (Nor do I think their reputation is deteriorated in the eyes of serious people.)

Little incentive to invest time and effort in creating a URSF client when there’s ~no support for a UASF in the first place.

There probably won’t be a re-org either because BIP110 never gets a majority of hash power, or because a re-org is simply prevented with a URSF/checkpoint/whatever. (Or both.)

The Knots crowd has become toxic enough that I do in fact hope they fork off. I’ll happily sell my BIP110 coins back to them—assuming there will be enough blocks on this chain for these transactions to confirm—and they can go their Bcash way.

I visited “Bitcoin Jungle” (Uvita, CR) a few days this week.
Normally when I go to circular economy projects (Arnhem, Rovereto, El Zonte…) I link up with the organizer(s) and seek out the locations where I can pay with bitcoin, but this time I decided to run the experiment a bit differently: I just went to wherever I felt like going and then asked if they accepted BTC.
Out of about a dozen places I visited…
1 accepted bitcoin. (S/O to The Fistcuff Pub!)
1 had a Bitcoin Jungle sticker but didn’t actually take bitcoin payments. (Whale Tail Brewery)
1 did not accept bitcoin but seemed genuinely interested and would look into it. (Coffee Bear)
Out of the other ~10, about half just said no, and the other half clearly didn’t even know what bitcoin was.
So is this a bad result? Frankly, it’s roughly what I would have expected. I’ve long believed that spurring bitcoin adoption by convincing merchants is an uphill battle. You might get a few boutique shops and bars to participate, and then they find it’s kind of a pain to teach all their personnel how to use wallets just for maybe a handful of bitcoiners that show up once in a while.
I do like these projects, and if you _do_ seek out the bitcoin accepting spots you can probably go a long way without touching fiat for a few days— yet we also shouldn’t overstate the success or impact of such local initiatives.
I suspect it might just be a bit too early for this still… but if we do want to create hotspots with truly widespread adoption, what would that require?
I’d say:
- Instant fiat conversion is probably a must.
- Printable QR codes (BOLT12/Silent Payments) to make it easier for merchants to keep accepting BTC even if sparsely used.
- Ideally there’d be a source of “fresh” BTC that’s brought into the economy, whether that’s from local miners, or expats that get paid in bitcoin, or Bitcoin tourists, or…
- Ability to pay tax in BTC would be great but probably a long-shot in most places.
- What else?..
