It's interesting that Adam Back opposes BIP-110, because his own work helped shape one of Bitcoin's core ideas.
Long before Bitcoin existed, Adam Back invented Hashcash, a proof-of-work system designed to combat email spam. The concept was simple but elegant: don't ban spam, make it economically expensive. Legitimate users barely notice the cost, while mass spammers suddenly face a significant financial burden.
Satoshi Nakamoto considered Hashcash so important that it became one of the foundational building blocks referenced in the Bitcoin whitepaper. In fact, Adam Back was the first person Satoshi contacted before publishing Bitcoin, specifically to verify the Hashcash citation.
This is why Adam Back's opposition to BIP-110 is philosophically consistent.
Hashcash never tried to decide which emails were "good" or "bad." It didn't censor content. It simply used economic incentives to make abuse expensive.
Likewise, Bitcoin's blockspace is already protected by a market. If someone wants to fill blocks with arbitrary data, they must compete by paying transaction fees. Those fees are earned by miners and ultimately strengthen Bitcoin's security budget. The market, not protocol-level content filtering, determines what gets included.
Adam Back has argued that BIP-110 attempts to solve a problem by introducing consensus restrictions where fee economics already provide an incentive-based mechanism. He has also warned that making protocol changes without broad consensus risks harming Bitcoin's credibility and setting an undesirable precedent.

🚨 BUKELE JUST SCHOOLING THE ENTIRE WORLD
El Salvador President Nayib Bukele dropped an EPIC video showing his country’s total transformation.
LOCKING UP CRIMINALS ACTUALLY WORKS.
I’m seeing a lot of good people posting about this story, but it needs to be trending.
If Ridglan Farms is shut down, that will be a MASSIVE win for the internet.
These are eight of the brave animal rescuers who were arrested today for rescuing dogs from animal experimentation. Multiple others are still awaiting booking.
Our jail support team has spoken with some of them, including Wayne. They say the rescuers are in good spirits but concerned about the safety of the animals.
TAKE ACTION: Call the Dane County Sheriff’s Office and ask them to return the 8 rescued beagles taken from the arms of activists who were carrying them to safety.

Imagine you're trying to escape any of the places recently bombed
You have the choice of taking heavy gold with you making your journey much harder and much more dangerous
Or simply remember a bunch of words/have a note with your seed phrase
One of these is infinitely better
While on vacation, this man took the time to help guide this confused swan back to the water below.
The bird's reaction when he is back on the water is pure joy. 🥹
