I think I found an unexpected problem with the most liquid BIP110 prediction market.
It defines the "Yes" condition based on a mix of timestamp ("11:59:59 PM") and blockheight ("the BIP-110 activation point"). But since those are not always in sync on bitcoin, there's a chance that we simply haven't reached that blockheight yet when we reach the timestamp when the measurement is supposed to happen.
In that case, the Yes condition would obtain unexpectedly: if we are only at block 965660 at the timestamp, instead of 965664, then -- at the time of measurement -- there won't be any "blocks that violate BIP-110 constraints" from BIP-110's activation height forward...but only because we haven't reached that blockheight yet.
So a person who thinks BIP110 won't activate might find it reasonable to bet Yes anyway, because even if BIP110 never gets enforced, you can still win if blocks just get slower than we currently expect them to.

Will BIP-110 activate and be enforced on Bitcoin by Sept 1 - 7, 2026?
Definition of ActivationAmendment due to logic:Check for violations after 64 blocks after the activation block, which is 965664. That block is curr...
My latest invention is Forkalicious: a contentious fork visualizer.
The website creates three characters, Alice, Bob, and Carol. Alice runs a "standard" bitcoin node that ignores the BIP110 soft fork. Bob runs a node that enforces the BIP110 soft fork. Carol runs a node that rejects the BIP110 soft fork. Then you pick how many miners enforce the rules of BIP110, from 0% to 100%. Then you generate blocks based on that assumption, and see how the blockchain looks on Alice's node, Bob's node, and Carol's node.

Today I learned BIP91 was a temporary soft fork. I didn't know bitcoin ever did one before. Some people say the expiration of a temporary soft fork counts as a hard fork; I disagree, and it's nice to have something to point to as a counterexample 
Here's a thing I wanna *use* but don't wanna build myself. These stores let you pay with L1 bitcoin if you use one of their partner apps to generate something called a Flexa Payment Code:
- Chipotle
- Home Depot
- Gamestop
- Barnes & Noble
The user needs a wallet with btc or another cryptocurrency in it, you use that money to fund what is essentially a gift card that works at any Flexa-supporting merchant, the merchant scans it, and you enjoy your product.
But there is no "web" interface for doing this. You can't just pay a lightning invoice and get a Flexa payment code out of it to present at Chipotle, etc. And Flexa's API is also permissioned, which is a turn-off for me.
But there's a potential workaround: at least three of their partner apps ARE permissionless. Nexus Wallet, Nighthawk Wallet, Zashi Wallet, and Coinbase Wallet are self-custodial wallets, and *can* generate Flexa payment codes.
So I'd love it if someone used an emulator, a scraper, and lightning to make a website where anyone can generate a Flexa code and pay with LN at Chipotle et. al.

The existence of a UASF for bip110 and a URSF against it has an interesting consequence for the spam war 
Wow, that flew under the radar. F2pool apparently launched lightning withdrawals some time before February 10 of last year. So five mining companies support it:
- F2pool
- Nicehash
- Braiins Pool
- Ocean Mining
- Lincoin Pool
And people said LN would take fees away from miners!
My latest invention is URSF-110, which does a User Rejected Soft Fork against BIP110. It run on regtest or mainnet, though I recommend not running it on mainnet til someone smarter than me takes a look. Learn more on my github:
