For anyone still interested in this clown show...
tried to push through a soft fork on Bitcoin-jr with ~one day notice, to freeze newly generated block rewards.
The rules just went into effect, and now that blockchain has split between upgraded and non-upgraded nodes.
Whether the split is temporary or permanent (Bitcoin-jr v. Bitcoin-jr Classic) remains to be seen.

Successfully sold my first chunk of bitcoin-jr (BJR AKA BTCB2).
First split it from BTC using
’ splitting tool: https://github.com/hsjoberg/bcashjr-wallet/releases/tag/v0.0.1
Then sold for BTC on NeoxEX: https://neoxa.exchange/trade/BTCB2_BTC
Use both the wallet and exchange at your own risk (I only did fairly small amounts), but it does work.

The testnet forkwar to determine PoW algo for Bitcoin-jr is more exciting than the BIP110 fork war itself was tbh.

Bdashers decided to use a testnet block header to randomly determine the proof-of-work algorithm for their forkcoin, but now testnet has been forked and they don’t know what to pick. (lol)

Just in case the Bdashers’ wipeout argument does stick around: Bitcoin nodes can always reject the BIP110 chain even in the extremely unlikely scenario that it would overtake the Bitcoin chain at some point, by running bitcoin-cli invalidateblock 0000000000000000000169eb6f811ddbd0daf343af7b62180cdb13e7c78dbc16.

BIP110 can as of now no longer be activated through hash power signaling.
The "mandatory signaling" window starts next week, which practically speaking means Bitcoin Knots nodes will stall and/or fork off-- unless basically all miners suddenly decide to adopt this nonsense after all.

The failure of BIP110 will reveal that social media drama is just noise and I think that's wonderful.

In a new episode of What Bitcoin Did with
,
talks about the game theory behind BIP110, which he believes makes it virtually guaranteed to succeed.
There was a lot of discussion about these dynamics in anticipation of the Segwit UASF (BIP148) in 2017; I for example wrote this article about it at the time: https://bitcoinmagazine.com/technical/op-ed-heres-why-all-rational-miners-will-activate-segwit-though-bip148
Note however that I at the start of that article laid out the assumptions for this game theory to play out. Arguably none of these assumptions hold up for BIP110.
The hash power support for BIP110 is incredibly low (significantly lower than for Segwit), and I don’t believe these miners will continue to mine a minority chain long enough for the difficulty to return to normal.
IMO BIP110 is a harmful upgrade, therefore I expect the market to value “110BTC” less than “LegacyBTC”. (This is the important one btw.)
BIP110 is more niche than BIP148 was, so a smaller percentage of users and miners will be aware of any game theory to act on even if that was rational.
In the unlikely event that a wipe-out of the legacy chain becomes a realistic possibility I would expect users and/or miners who oppose BIP110 to deploy some kind of checkpoint in order to prevent this.
TL;DR: BIP110 nodes will probably fork themselves off the network when mandatory signaling starts, and either end up on a dead chain or become a forkcoin (that would likely require further protocol changes to then stay alive).

In August 2017, users proved that miners can’t block a valuable upgrade.
In August 2026, miners will prove that users can’t push through a harmful upgrade.

What's the Plan For a Post-Quantum Soft-Fork: Bitcoin 2026 panel featuring Jonathan Bier, Mike Casey, Christian Papathanasiou and Ian Smith, and moderated by myself.

Preserving the Historical Record of Bitcoin Knowledge: Bitcoin 2026 panel featuring Jonathan Bier, Michael Goldstein and myself, and moderated by Paul Rosenberg.

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.
